I feel very fortunate to have found Ideal Attic Insulation to work on the attic and crawlspace of our newly purchased home. From the start, Jorge came to provide a free inspection, and he was extremely professional and thorough. He personally went into the attic and crawled into the crawlspace to check every detail. After his inspection, he gave us a very fair estimate with a clearly written and complete scope of work. We also requested quotes from other companies, but it became clear that Ideal Attic Insulation—and especially Jorge—was the most professional, responsible, and knowledgeable. Jorge even helped us connect with other reliable handymen for additional repairs we needed around the house, which we truly appreciated. Once our plumbing repairs were completed, we scheduled the attic and crawlspace work. Jorge’s team handled the attic cleaning, sealing, rodent-proofing and new insulation installation. In the crawlspace, they performed a full cleaning, rodent-proofing, and installed a new vapor barrier. The scheduling was quick, and everything was completed within three days. The workmanship was excellent—clean, organized, and very professional. We really trust Jorge and appreciate his honesty, experience, and dedication. I highly recommend Ideal Attic Insulation to anyone looking for attic or crawlspace services. We will definitely continue using this company in the future. Highly recommended!

Jorge is the best. My wife and I had contacted 4 companies, and by far Ideal Attic Insulation was the winner. With us it wasn't all about price, but quality, knowledge of the trade and experience. We had our old insulation removed when we replaced our roof. Yes, like lot of us when your roof is compromised you have issues with rodents. Once our roof was completed, we set our appointment with Jorge. He came out the following afternoon, and boy was it hot. He inspected our entire attic and came up with a game plan to vacuum and sanitizing our entire attic space. He took a lot of pictures and shared areas of concern with us. We had the roofer's comeback out and tighten up area that may have been able to be compromised. once these areas were tightened up Jorge sent out his crew to install mess wire and stray foam around vent pipes, etc. Jorges recommended we wait a few weeks to install the insulation to see if there were any signs of rodents. After a few weeks and weekly inspections by Jorge and his crew, there were no signs of pests. They installed the insulation, and we could not be happier. We highly recommend Ideal Attic Insulation. Don't waste your time looking for other insulation companies call ideal Attic Insulation and know you made the right decision.

After reaching out to several insulation companies and getting quotes from 4 of them, we picked Ideal Attic to clean, rodent proof, and insulate our attic and floors as well as cleaning the ducts on our house that lies deep in the Santa Cruz mountains. Jorge got me an extremely competitive quote, and even after pressing the rest of the companies, Jorge’s original quote was still way below the other companies’. He sent out two teams the following Saturday and got everything done in one day. Everyone worked extremely hard and everything got done as promised. The attic team ran into a problem with a recessed light that went out while vacuuming in the area. They weren’t able to fix it on the spot, but Jorge and his dad came out a few days later and fixed it. Overall I’m very pleased with the price, quality, and the company’s dedication to making the customer happy, and I would therefore recommend Ideal Attic.

Idan does not disappoint! This is our second time using his services, and this time I went straight to him without even shopping around. His team is responsive, efficient, and highly professional. A major bonus is their expertise with home insurance systems, which made that part of the process effortless for us. Later, despite a dispute over the scope of work (which was due to a miscommunication, not his fault), he stood by his word and honored his promises, even when it resulted in a significant financial loss for him. His integrity, particularly in that situation, is truly commendable!

After experiencing a roof leak that led to multiple issues, I interviewed several companies before ultimately choosing Leader Restoration, and I’m so glad I did. From start to finish, the process was smooth and professional. I worked closely with project manager Idan, who was knowledgeable, responsive, and easy to work with. Leader Restoration handled everything seamlessly—including coordinating with my hygienist for the final mold inspection, which we passed on the first try. Their expertise in mold remediation and dedication to quality restoration services truly stood out. I couldn’t be happier with the results and highly recommend them to anyone facing water or mold issues.

Tyler Barros★★★★★4 months ago

We discovered mold during our home remodel and contacted Leader Restoration. Idan, the project manager, was incredibly professional, and Julio, the lead technician, did excellent work. The mold remediation process was smooth, the price was competitive, and we got clearance in less than a week. Highly recommend them for reliable mold removal and restoration services!

As a general contractor, I would highly recommend The Bay Area Insulation. Miguel and his team are reliable, respectful and work well with my team. I would highly recommend them.

Steve Johnson★★★★★7 months ago

I had an insulation company all lined up to reinstall new insulation in my attic. I even paid them in full, and in advance. Four days before the job, I got a text saying they were going to bail out, and they did. Enter The Bay Area Insulation, and Miguel Vilchez. I contacted Miguel on a Saturday morning around 8:30 am "out of the blue", and explained my situation. He was at my place in Redwood Shores within 90 minutes to talk and do a site inspection. A few hours later, I received a quote, competitive, and immediately gave them the job. Monday morning, the original day of the aborted install, Miguel was picking up the special insulation I wanted, and by 1:30 pm he had a crew onsite and began the project. At 7:00 pm they finished, and the job was even better than I had asked for -- and I'm an anal engineer! The bottom line is that I wholeheartedly recommend Bay Area Insulation and Miguel Vilchez for an insulation project. I even immediately gave his business card to my favorite "big-time" contractor, and said, "You've got to use this guy."

We discovered a bad rodent infestation in the crawl space and attic area of our new home. As a result, all insulation required removal and replacement. SDI held our hand thru the entire process. They provided 3 bid options, took care to ensure we understood each package/scope, and came out to meet with us for accuracy. Once the project commenced, SDI was professional, punctual and incredibly efficient. The team would provide regular updates. We felt very well cared for and important as their client. It can be hard and stressful finding reliable and trustworthy vendors that aren’t over charging and/or cutting corners. Do your project right the first time with SDI. We had an amazing experience. Highly recommend!

Mark Howser★★★★★2 years ago

I've used SDI Insulation on 3 of my projects throughout the years... they never disappoint! They're always on time, their work is superb and have never failed an inspection for their insulation work. I'm in the custom home building industry and it's hard to find a reliable and professional insulation company in the Bay Area. You get what you pay for and SDI is my go to company for quality insulation work. I definitely recommend these guys!

Kathleen Willis★★★★★9 years ago

Excellent job from start to finish. Our project manager, Dennis, did an excellent job addressing our concerns relative to noise and draft. We followed his advice and are completely satisfied with the results. The installation team consisted of 3 very capable and delightful young men who did a terrific job. The guys worked together very well, and they were polite and professional. The supervisor arrived to put the finishing touches on the job and the fellows cleaned up beautifully. I highly recommend SDI!

Isaac from Atticali was very professional and worked with us until the end of an infestation problem. We are grateful for his committment through the process.

Eric Tam★★★★★2 years ago

Overall we had a great experience! Thorough inspection, friendly personality, good price and effective at catching the mouse at our house. We recently had a mouse gotten into the house and were extremely concerned with a little one at home! Once I reached out, David and Francisco came in next day, thoroughly inspected for any openings, and set up traps that caught the mouse in the same day! They then came in next day to help fill in any gaps from the outside with wire meshes + concrete for holding the mesh in place. They also filled in gaps from the inside at the attic and in the kitchen to prevent any more rodents from coming in! So far we haven’t seen more! But if we do, we got a multi year warranty that gave us a peace of mind!

Frequently Asked Questions — Spray Foam Insulation in Burlingame

These are the questions Burlingame homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 6 verified Burlingame contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Burlingame?▼
Homeowners in mixed climates like Burlingame, 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 Burlingame?▼
For most homes in Burlingame, 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 in Burlingame, CA?▼
In Burlingame, CA and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. 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 in Burlingame costs $2,000–$6,000. Most Burlingame 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 in Burlingame, CA?▼
When searching for a spray foam contractor in Burlingame, CA, look for ones 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 Burlingame 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 in Burlingame 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.
