Current Offers
Free Estimate with Written Price Before Any Work Starts
Every San Diego homeowner gets a free, no-obligation inspection and a written price before anything gets installed. That price is guaranteed before work begins – no door-step surprises, no add-ons after the fact. This is our standing offer, not a seasonal gimmick.
Valid through March 31, 2027. Mention this offer when you call (619) 344-8538.
Attic Insulation Tune-Up and Visual Inspection
For homes in Chula Vista, El Cajon, and the broader San Diego metro that haven’t had their attic checked in five-plus years, we offer a pull-down ladder inspection and thermal review of your existing insulation. We’ll tell you honestly whether your material is still doing its job or whether the coastal humidity has compressed it into something closer to a blanket than a thermal barrier. No charge for the inspection itself.
Valid through March 31, 2027. Mention this offer when you call (619) 344-8538.
Senior and Military Courtesy Discount
San Diego is a Navy town, and a lot of our neighbors in Clairemont and Mira Mesa have served. We extend a standing courtesy on insulation work for active-duty military, veterans, and homeowners 65 and over. Ask us about the current amount when you call – it varies by project scope, and we’ll apply it automatically before we hand you the written price.
Valid through March 31, 2027. Mention this offer when you call (619) 344-8538.
Spray Foam Insulation Upgrade Credit
If you’re already planning an attic insulation project and you’re considering spray foam insulation – a two-part liquid that expands on contact and seals gaps airtight – ask about applying the cost of your initial inspection toward the foam application itself. This helps San Diego homeowners who want the air-sealing performance of closed-cell or open-cell products but want to test the waters first. Works with Icynene, Demilec, and the other brands we carry.

If it’s not done right, we come back and make it right at no charge – 365 days, in writing, included on every job. When you’re comparing insulation companies, compare the follow-through, not just the first visit.

How Much Does Insulation Cost in San Diego?
Most attic insulation jobs in San Diego run between $1,800 and $4,200 for standard homes, with spray foam running higher because of the material and application method. The final number depends on attic square footage, current insulation depth, access, and whether you want fiberglass batts, blown-in, or foam.
Here’s what pricing generally looks like in the San Diego market:
- Blown-in fiberglass or cellulose attic insulation: $1,800 to $3,400 typical for a 1,200 to 1,800 square foot home
- Fiberglass batt installation: $1,400 to $2,800 depending on depth needed
- Open-cell spray foam on the attic floor: $2,800 to $5,200
- Closed-cell spray foam on the roofline: $6,000 to $12,000+ depending on roof geometry
We give you the exact written number before any work starts. Every single time. That’s the Kingswell Way: say the price, show up in the window, leave it cleaner than you found it, put the guarantee in writing, and come back if it fails.
Which Insulation Brands Do You Install in San Diego?
We work with eight leading insulation manufacturers: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That’s deliberate. We don’t want to be married to one brand and force it onto every house. We walk your attic, look at what you’ve got, and recommend the material that fits your home’s condition and San Diego’s climate – not whatever happens to be sitting on the truck that morning.
Our techs are trained across all eight brands, so the recommendation is genuinely about fit. Wool was the first insulation. Woolsey keeps the idea in the name – and in the way we approach choices.
Is Your Attic Insulation Affected by San Diego’s Coastal Humidity?
It is, and this is one of the most common things we see in homes from Ocean Beach to La Jolla. Fiberglass batts can absorb moisture from the marine layer, compress under their own weight, and lose R-value over time. Cellulose settles. Spray foam, applied correctly, doesn’t have that problem – the air-sealing property is what makes it appealing for coastal homes where the humidity works against traditional materials year-round.
In 23 years of working in San Diego attics, we’ve learned to plan material selection around the microclimate of your specific neighborhood. A house in Pacific Beach has different attic conditions than a house in Santee. That’s not a throwaway line – it changes the recommendation.
Frequently Asked Questions About Insulation Specials in San Diego
For most San Diego homes, adding new insulation on top of existing material is cheaper than a full removal and replacement. If the current material is dry and intact, topping it off with blown-in fiberglass or cellulose costs between $1,800 and $3,400 depending on attic size. If you’ve had a roof leak, animal intrusion, or the insulation is compressed and useless, replacement is the better long-term value. Call (619) 344-8538 and we’ll give you an honest recommendation and written price.
We run simple offers year-round: free estimates, a senior and military courtesy, and our 365-Day Done Right Promise included on every job. San Diego’s climate doesn’t have a dramatic “insulation season” the way colder cities do, but we do see a spike in attic calls during summer heat waves and January cold snaps. The best time to insulate is before either one hits.
In most cases, yes. We schedule attic insulation projects in San Diego within 5 to 10 days depending on material availability and your neighborhood. Call (619) 344-8538 and we’ll give you a real answer for your area, not a vague window. Estimates are always free and always come with a written price.
We cover the full San Diego metro: from Chula Vista and National City in the south, up through Downtown, North Park, Clairemont, Mira Mesa, Poway, Escondido, and out toward El Cajon and La Mesa. If you’re unsure whether we service your zip code, just ask when you call.
The promise is straightforward: if a repair or installation isn’t right within 365 days, we come back and fix it at no charge. It’s included in writing on every job, every time, with no fine print about materials or labor. That’s what makes it different from the warranty language you’ll see from some other San Diego insulation contractors.
