After a home energy audit, we realized the condition of our insulation. The contractor recommended spray foam in our crawl space and did a fantastic job. The team was professional and did not attempt to sell us anything. All the gaps were closed well, and our house now feels warmer and quieter.

We hired them to insulate our attic, and the difference in indoor temperature was noticeable right away. The crew was quick, polite, and cleaned up after themselves. Our energy bill has already gone down this month—worth every penny.

Miranda Roger★★★★★2 weeks ago

I am thoroughly impressed with the quality of work and customer care. San Diego Thermal Insulation provided a customized solution for our complex attic with multiple roof levels. Their crew was skilled, patient, and ensured every cavity and eave was properly insulated and sealed. The before-and-after difference is night and day. Our home retains warmth on cool nights and resists heat during the day far more effectively. A trustworthy and highly skilled company.

Whitney Alexandra★★★★★2 weeks ago

Outstanding service from a company that truly understands San Diego's unique temperature swings. From the initial consultation, their knowledge of both coastal and inland microclimates was evident. They provided a clear, fair plan and executed it flawlessly. The installation team was punctual, respectful, and their workmanship is top-notch. Our home is now consistently comfortable day and night, and we've already noticed a decrease in our cooling costs. Highly recommend this knowledgeable local team.

Chaim Dustin★★★★★2 weeks ago

We contacted San Diego Thermal Insulation to address the intense heat gain in our east-facing rooms, and the results have been phenomenal. Their team provided a tailored solution that combined radiant barrier installation in the attic with upgraded ventilation. The crew was professional, efficient, and left the worksite impeccably clean. The difference is immediate and dramatic; our home now stays cool much longer into the afternoon, and our air conditioner finally gets a rest. Perfectly suited for our local climate.

For a long time, we paid little attention to our crawl space, but the accumulation of moisture began to impact our house. Leo and his crew performed an excellent task of clearing it out, sealing it properly, and adding insulation. They guided us through each phase and highlighted spots we hadn’t thought about. The air quality in our home has improved, and I feel assured that we have prevented potential issues. The dedication and professionalism of the team were remarkable. It’s a tremendous comfort to realize our crawl space is now well-maintained!

Naty Hernandez★★★★★a year ago

I was dealing with moisture and damaged insulation in my crawl space, and this company did an amazing job. Leo installed a vapor barrier, replaced the insulation, and ensured everything was dry and clean. The team explained every step and worked quickly but thoroughly. Now, my crawl space is well-protected, and I couldn’t be happier with their service!

Rosy Escobar★★★★★a year ago

Leo from Crawl Space And Attic Pro was fantastic! He and his team tackled the crawl space cleaning with such precision and care. After clearing out all the dirt and debris, they installed a new vapor barrier that has completely eliminated our moisture issues. Leo explained every step clearly, and I felt confident we were in great hands. Now the air in our home feels cleaner, and we don’t have to worry about mold anymore.

Frequently Asked Questions — Spray Foam Insulation in Poway

How much can spray foam insulation save on heating and cooling bills in Poway?▼
Homeowners in mixed climates like Poway, CA typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Poway?▼
For most homes in Poway, CA, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost?▼
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic costs $2,000–$6,000. Most homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor?▼
Look for contractors who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
