Insulation in Florence-Graham, CA
Spray foam insulation in Florence-Graham solves a problem most of these pre-1950s bungalows share: bare attics and hollow stud walls that let late-afternoon heat pour straight through the roof. We apply open-cell and closed-cell foam to seal and insulate in one pass, cutting cooling loads in a community that sits far enough inland to miss the marine layer and never gets the coastal breeze. Call (213) 782-8141 to talk to a live person 24/7 about getting your Florence-Graham home comfortable.
Why Florence-Graham Homes Are Different
Florence-Graham is an unincorporated LA County community packed with 1920s through 1950s wood-frame bungalows and converted multi-family rentals, most built before California had meaningful insulation requirements. When we open attics here, we routinely find original construction with no insulation at all, just exposed rafters and dusty plaster. Many homes are absentee-owned rentals where insulation work has been deferred for decades because no one wanted to spend the money, and tenants just live with the drafts and the heat.
The climate makes it worse. Florence-Graham sits inland enough that the Pacific marine layer rarely reaches it, and the concentration of asphalt and concrete across the South LA basin creates a pronounced urban heat island. Summer highs run well above what nearby beach cities experience, and most of these homes only got central AC recently, if at all. That means radiant heat through the roof is the single biggest comfort problem, and it makes attic insulation and radiant barriers the highest-priority upgrades here.
There’s another practical wrinkle: Florence-Graham falls under LA County jurisdiction, not City of LA. Contractors have to pull permits through LA County Building and Safety rather than LADBS, which means a different fee schedule and inspection workflow. Firms that mostly work a few blocks north inside city limits trip over this. We’re familiar with the County process and handle it from permit to final inspection.
Our Main Florence-Graham Services
Most Florence-Graham homeowners call us first about two things: attics that bake the bedrooms below them, and crawl spaces that leak musty air up through the floor. Here’s how each works in this community.
Attic Insulation in Florence-Graham
In Florence-Graham, attic insulation is where we start because the roof is the biggest heat source in these old bungalows. We assess the bare attic, seal the air leaks, then install the right R-value for a South LA basin summer. Most jobs are completed in a single visit, and the 90-Day Done Right Promise means if it’s not right, we make it right. Full details: Attic Insulation in Florence-Graham.
Crawl Space Encapsulation & Vapor Barrier in Florence-Graham
Older Florence-Graham homes often have vented crawl spaces leaking damp ground air into the living space. We seal the ground with a vapor barrier, close the vents, and condition the space so your floors stop feeling damp and your indoor air improves. It’s a one-contractor job with no juggling trades. See the full scope: Crawl Space Encapsulation & Vapor Barrier in Florence-Graham.

Spray Foam Insulation in Florence-Graham
Spray foam insulation in Florence-Graham is the most direct fix for the bare attics and hollow walls in these pre-1950s bungalows. Closed-cell foam adds structural strength and a full air seal, while open-cell foam delivers high R-value per inch at a lower cost, and both stop the heat that keeps these South LA basin homes uncomfortable from May through October. Because the foam expands into every void, it fills the gaps that batt insulation never touches in older construction. For a deeper look at how spray foam works in homes like these, see our Spray Foam Insulation guide. Neil Ashford’s crews handle every foam job in Florence-Graham with the same up-front pricing and single-visit closeout.
Open-Cell Spray Foam
Signs you need it
You feel heat radiate down from the attic even after dark, and the AC runs for hours without fully cooling the house.
What it costs in Florence-Graham
Open-cell spray foam in Florence-Graham typically runs $1.20 to $2.20 per board foot installed, totaling about $1,800 to $3,600 for a typical 1,500-square-foot attic.
How we do it
We prep the attic, spray the foam to the target depth, let it cure, and verify the R-value with a depth check before we leave.
Closed-Cell Spray Foam
Signs you need it
Your walls are hollow, you feel drafts at the baseboards, and you want the added structural reinforcement closed-cell foam provides in older wood framing.
What it costs in Florence-Graham
Closed-cell spray foam in Florence-Graham runs $2.50 to $4.00 per board foot, typically $3,000 to $6,000 for a full attic application.
How we do it
We spray the foam in lifts against the roof deck or wall cavities, trim any excess after cure, and confirm the full depth was achieved.
What Spray Foam Insulation Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Open-cell spray foam (per board foot) | $1.20 - $2.20 |
| Closed-cell spray foam (per board foot) | $2.50 - $4.00 |
| Typical attic spray foam job | $1,800 - $6,000 |
Is spray foam safe for older Florence-Graham homes?
Yes, when applied by a trained crew. Spray foam must be mixed and sprayed correctly, and the space must be ventilated during cure. We’re licensed and insured, and we monitor all applications. Call (213) 782-8141 to talk through your setup.
Can you spray foam a Florence-Graham attic in one day?
Most open-cell attic applications are done same-day. Closed-cell takes longer because it’s applied in lifts. We’ll give you an exact schedule with your free estimate. Call (213) 782-8141; a live person answers 24/7.
Blown-In Insulation in Florence-Graham
Blown-in insulation in Florence-Graham gives these old wood-frame homes a fast, affordable way to get real attic R-value without disturbing original plaster ceilings. We blow cellulose or fiberglass over bare attics or existing thin layers, bringing the home up to current efficiency in an afternoon. For a full breakdown of how the material behaves in a South LA climate, see our Blown-In Insulation hub page. Neil Ashford’s techs do blown-in work here as a single-visit job with upfront pricing.
Blown-In Cellulose
Signs you need it
Your attic has thin, patchy, or no insulation, and your ceiling feels warm to the touch on hot afternoons.
What it costs in Florence-Graham
Blown-in cellulose in Florence-Graham runs $1.10 to $1.80 per square foot, or about $1,200 to $2,700 for a typical 1,000-square-foot attic.
How we do it
We air-seal the attic floor, mark target depth, and blow the cellulose to the required R-value with a calibrated machine.
Blown-In Fiberglass
Signs you need it
You want a moisture-resistant material with consistent R-value, and your attic is accessible enough for a fast install.
What it costs in Florence-Graham
Blown-in fiberglass in Florence-Graham runs $1.40 to $2.60 per square foot, typically $1,400 to $3,000 for a standard attic.
How we do it
We prep the access, run the hose to the attic, and distribute the fiberglass evenly to the marked depth, then verify R-value.
What Blown-In Insulation Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Blown-in cellulose (per sq ft) | $1.10 - $1.80 |
| Blown-in fiberglass (per sq ft) | $1.40 - $2.60 |
| Typical attic blow-in job | $1,200 - $3,000 |
Does blown-in insulation work in a Florence-Graham summer?
Yes. A properly air-sealed attic with full-depth blown-in insulation cuts attic temps substantially and lightens the cooling load. It’s the best cost-to-comfort ratio for these older homes. Call (213) 782-8141 for an exact quote, free.
Can you top up old insulation instead of replacing it?
Usually, yes, if the existing material is dry and not rodent-damaged. We inspect first and tell you honestly whether removal is needed. Call (213) 782-8141 to schedule that check.
Radiant Barrier Installation in Florence-Graham
Radiant barrier installation in Florence-Graham targets the one thing these dense, inland neighborhoods can’t avoid: direct sun on the roof. A radiant barrier blocks most of that radiant heat before it ever reaches your insulation and living space, which is why it’s such a high-impact upgrade here. For the full technical explanation, see our Radiant Barrier Installation hub. Neil Ashford’s crews pair it with attic ventilation so it actually does the job.
Attic Radiant Barrier
Signs you need it
Your attic is unbearably hot by 10 a.m., and the AC runs almost constantly from early afternoon into the evening.
What it costs in Florence-Graham
Attic radiant barrier in Florence-Graham runs $0.80 to $1.50 per square foot, or about $800 to $1,800 for a typical attic with a 1,200-square-foot footprint.
How we do it
We staple a perforated foil barrier to the underside of the rafters, keeping the air gap that lets it reflect heat rather than absorb it.
Radiant Barrier Foil
Signs you need it
Your roof deck faces full sun all afternoon, and the upstairs rooms are consistently 8 to 12 degrees hotter than other rooms.
What it costs in Florence-Graham
Radiant barrier foil in Florence-Graham runs $0.50 to $0.90 per square foot for the material, with installation labor adding $1.20 to $2.50 per square foot.
How we do it
We roll the foil across the attic floor or rafter faces, tape the seams, and confirm the installation reflects heat where it matters.
What Radiant Barrier Installation Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Foil material (per sq ft) | $0.50 - $0.90 |
| Installation (per sq ft) | $1.20 - $2.50 |
| Typical attic radiant barrier job | $800 - $1,800 |
Will a radiant barrier lower my AC bill in Florence-Graham?
Yes, often by 10 to 15 percent on peak summer days when combined with adequate attic insulation. It reduces the heat entering the attic, so your AC works less. Call (213) 782-8141 for a realistic expectation based on your home’s orientation.
Does a radiant barrier work on shingle roofs?
Yes. It’s installed inside the attic, applied to rafters or the floor, so it works with any roof type. The air gap is what matters, not the shingle material. Call (213) 782-8141 for a free attic assessment.
Insulation Removal & Replacement in Florence-Graham
Insulation removal and replacement in Florence-Graham is usually driven by rodent damage, old vermiculite, or water-damaged batt insulation that’s lost its R-value. These older attics often carry decades of dust, pest waste, and compaction that no top-up can fix. For the full scope of this work, see our Insulation Removal & Replacement hub. Neil Ashford’s team does removal and re-insulation as a single cleanly sequenced job.
Attic Insulation Removal
Signs you need it
Your attic insulation is compressed, rodent-soiled, or water-stained, and you can smell mustiness in the rooms below.
What it costs in Florence-Graham
Attic insulation removal in Florence-Graham runs $1.50 to $2.50 per square foot, typically $1,500 to $3,000 for a standard attic.
How we do it
We use a contained vacuum system to pull out the old material, bag it, and clean the attic floor before the new insulation goes in.
Contaminated Insulation Removal
Signs you need it
You see droppings or nesting material in the attic, or a home inspector flagged contaminated insulation before a sale.
What it costs in Florence-Graham
Contaminated insulation removal in Florence-Graham adds $0.50 to $1.00 per square foot over standard removal, so about $2.00 to $3.50 per square foot total.
How we do it
We remove the contaminated material in sealed bags, sanitize the surfaces, and confirm the space is clean before insulating.
What Insulation Removal & Replacement Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Removal only (per sq ft) | $1.50 - $2.50 |
| Contaminated removal (per sq ft) | $2.00 - $3.50 |
| Removal plus new blown-in insulation | $2,500 - $5,500 |
Is it cheaper to just add new insulation on top?
Sometimes, but only if the existing material is clean and dry. In Florence-Graham attics with rodent activity, leaving contaminated material in place just seals the problem in. Call (213) 782-8141 and we’ll tell you straight which route makes sense.
How long does removal and replacement take?
Most Florence-Graham attic jobs finish in one day: removal in the morning, new insulation in the afternoon. Larger or heavily contaminated attics may take two. Call (213) 782-8141 for your exact schedule with a free estimate.
Attic Air Sealing in Florence-Graham
Attic air sealing in Florence-Graham fixes the silent problem behind many high energy bills in these old bungalows: conditioned air leaking out through gaps, cracks, and unsealed penetrations at the attic floor. Sealing these leaks before adding insulation doubles the value of every dollar you spend on the insulation itself. For the technical process, see our Attic Air Sealing hub. Neil Ashford’s crew handles sealing and insulation as one coordinated job.
Attic Floor Air Sealing
Signs you need it
Your rooms feel drafty despite closed windows, and the AC runs long cycles while upstairs stays warm.
What it costs in Florence-Graham
Attic floor air sealing in Florence-Graham runs $1.00 to $2.00 per square foot, typically $1,000 to $2,500 for a 1,200-square-foot attic floor.
How we do it
We move insulation aside, seal every crack and seam at the attic floor with foam and caulk, then restore or add insulation over it.
Top Plate & Penetration Sealing
Signs you need it
You see daylight around wiring, plumbing vents, or the top plates in the attic, and you feel drafts near interior walls.
What it costs in Florence-Graham
Top plate and penetration sealing in Florence-Graham runs $1.50 to $2.50 per linear foot of sealed joint, with most jobs falling between $600 and $1,800.
How we do it
We foam every penetration, caulk the top plates, and seal around chimneys and flues with fire-rated materials.
What Attic Air Sealing Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Full attic floor sealing (per sq ft) | $1.00 - $2.00 |
| Top plate and penetration sealing | $600 - $1,800 |
| Sealing plus new blown-in insulation | $2,200 - $5,000 |
Should I air seal before or after adding insulation?
Before. Sealing first locks in the benefit of the new insulation, and doing both in one visit is cheaper than two visits. Call (213) 782-8141 to sequence it right.
Does air sealing really make a noticeable difference in Florence-Graham?
Yes, in these drafty older homes, sealing typically cuts air leakage by 20 to 40 percent, and you feel it immediately: fewer drafts, steadier temps, less dust. Call (213) 782-8141 for a blower door test to measure your current leakage.
Wall Insulation in Florence-Graham
Wall insulation in Florence-Graham addresses the hollow stud walls that are standard in these 1920s to 1950s wood-frame homes. Most were built with zero wall insulation, so heat moves straight through the plaster and lath. We can insulate existing walls without tearing them open. For a full walkthrough, see our Wall Insulation hub. Neil Ashford’s background-checked technicians do wall work here with minimal disruption.
Injection Foam Wall Insulation
Signs you need it
Your walls feel warm in summer and cold in winter, and knocking on them gives a hollow, echoey sound.
What it costs in Florence-Graham
Injection foam wall insulation in Florence-Graham runs $2.50 to $4.50 per square foot of wall area, typically $3,000 to $7,500 for a full exterior wall retrofit.
How we do it
We drill small access holes in each stud bay, inject foam to fill the cavity, then patch and touch up the holes.
Drill & Fill Wall Insulation
Signs you need it
Your home has enclosed wall cavities you want insulated, and you don’t want to remove interior plaster or exterior siding.
What it costs in Florence-Graham
Drill and fill wall insulation in Florence-Graham runs $1.80 to $3.00 per square foot, typically $2,400 to $5,000 for a bungalow’s exterior walls.
How we do it
We drill from inside or outside, blow cellulose or fiberglass into each cavity to full density, then patch to match the surrounding finish.
What Wall Insulation Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Injection foam (per sq ft wall) | $2.50 - $4.50 |
| Drill & fill (per sq ft wall) | $1.80 - $3.00 |
| Typical whole-wall retrofit | $2,400 - $7,500 |
Will wall insulation make my Florence-Graham home too hot?
No. Insulation slows heat movement in both directions, so it helps keep heat out in summer and inside in winter. It doesn’t generate heat. Call (213) 782-8141 to discuss your specific wall assembly.
Can you insulate the walls without damaging my plaster?
Yes, drill-and-fill and injection methods access the cavities through small holes, with careful patching afterward. For older plaster, we use techniques that minimize vibration. Call (213) 782-8141 for an assessment.
Attic Cleaning & Rodent Proofing in Florence-Graham
Attic cleaning and rodent proofing in Florence-Graham matters because these older wood-frame homes with easy soffit access are prime nesting ground for roof rats and squirrels. Rodents destroy insulation, chew wiring, and leave waste that affects indoor air. We clean the whole space and close every entry point. For the full scope, see our Attic Cleaning & Rodent Proofing hub. Neil Ashford’s uniformed techs handle the dirty work so you don’t have to.
Attic Cleanout
Signs you need it
You hear scratching at dawn, see droppings in the attic, or notice the insulation has been flattened into paths and nesting areas.
What it costs in Florence-Graham
Attic cleanout in Florence-Graham runs $800 to $2,000 depending on the attic size and depth of contamination.
How we do it
We remove all loose insulation, vacuum the deck, bag the waste, and prepare the space for new insulation.
Rodent Proofing & Exclusion
Signs you need it
Rodents keep returning even after you seal one entry; you find gnawed wood, torn ductwork, or droppings near the eaves.
What it costs in Florence-Graham
Rodent proofing and exclusion in Florence-Graham typically runs $1,000 to $2,500, covering every roof, soffit, and vent entry point.
How we do it
We inspect the full perimeter, seal every gap with steel mesh and foam, and confirm no entry point remains open.
What Attic Cleaning & Rodent Proofing Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Attic cleanout | $800 - $2,000 |
| Rodent proofing & exclusion | $1,000 - $2,500 |
| Cleanout plus proofing plus new insulation | $3,000 - $8,000 |
Do you handle the rodents or just the insulation?
We do exclusion: sealing every entry point so rodents can’t get back in. If live animals are present, we coordinate with a licensed pest-control partner, then we clean and re-insulate. Call (213) 782-8141 to map out the right sequence.
How do I know if my Florence-Graham attic has rodent damage?
Look for droppings, flattened insulation paths, chewed wires, or a musty urine smell. Even without seeing animals, these signs mean the attic needs cleaning and proofing. Call (213) 782-8141 for an inspection.
Home Energy Audit in Florence-Graham
A home energy audit in Florence-Graham is the diagnostic starting point that tells us exactly where your home is leaking air and heat. For these older bungalows with decades of deferred work, it prevents spending money on insulation that misses the real problem. For the full audit breakdown, see our Home Energy Audit hub. Neil Ashford’s team uses the audit to make every other service more targeted and cost-effective.
Blower Door Test
Signs you need it
You feel drafts in specific rooms, your energy bills spike each summer, and you want to know exactly how leaky your house is.
What it costs in Florence-Graham
A blower door test in Florence-Graham typically runs $200 to $400 as part of a full energy audit.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure the air leakage rate in CFM.
Thermal Imaging Inspection
Signs you need it
Rooms feel different wall-to-wall, some walls are hot to the touch in summer, and you suspect missing or settled insulation.
What it costs in Florence-Graham
Thermal imaging inspection in Florence-Graham runs $150 to $400 depending on home size, often bundled with the blower door test.
How we do it
We scan every wall, ceiling, and floor with an infrared camera to map hot and cold spots, revealing exactly where insulation is missing or failing.
What Home Energy Audit Costs in Florence-Graham
| Item | Typical range in Florence-Graham |
|---|---|
| Blower door test | $200 - $400 |
| Thermal imaging inspection | $150 - $400 |
| Full audit package (blower door, thermal, inspection) | $350 - $800 |
Is a home energy audit worth it before insulating?
Yes, especially in Florence-Graham, where houses vary wildly. The audit tells you which upgrade will actually cut your bills, so you don’t pay for the wrong fix. Call (213) 782-8141; free estimates are part of how we work.
Can the audit qualify me for utility rebates?
Often, yes. Many Florence-Graham residents are income-qualified for free retrofits through SCE’s Energy Savings Assistance Program and SoCalGas’s weatherization program. We help you check eligibility. Call (213) 782-8141 to start that conversation.

What Florence-Graham Customers Say
"The estimate had every line itemized - removal, sealing, baffles, the blown-in by the bag - and the final invoice matched it exactly. Two other companies quoted a single number and could not tell me what R-value they were installing."
- Priya Raman"They did the energy audit first - blower door and thermal camera - and showed me exactly where the house was leaking before selling me anything. The fix ended up being air sealing plus a modest attic top-up, not the full replacement another company pushed."
- Grace Nakamura"Solid work on the spray foam in the rim joists and the garage ceiling. Scheduling slipped a day because of rain, which they called about ahead of time. Would use them again."
- Tom Reinholt
