Donovan Ellis★★★★★a month ago

We turned our attic into usable storage space, so improving the insulation while at it made sense. The radiant barrier first covered the entire roof underside, followed by a layer of blown-in fiberglass. The process was neat and fast, and they ensured ventilation channels were not blocked. The attic now stays cool enough to walk in, even during hot days, and the energy savings showed up within a month.

Emmett Carrington★★★★★2 months ago

The attic insulation in our home had been in place for decades and was no longer effective. Attic Wizard came in, removed the old material, and replaced it with high R-value spray foam. The difference in temperature throughout the upper rooms is noticeable. Their crew finished the project in just a few days and made sure the entire roofline was properly sealed.

Ellie Howard★★★★★2 months ago

We needed a full attic cleanup and insulation replacement before putting in new ductwork. Attic Wizard handled the job, and Mark led the crew onsite. First, they vacuumed out all the old insulation, then checked for leaks or damage in the attic floor. After that, they made sure every opening was sealed before fresh cellulose was blown in. They also boxed around the hatch and kept soffit vents clear with baffles, which the inspector noted was done correctly. The entire process was easy to follow since they explained what they were doing as they went. Within days, the attic was completely transformed, and the upstairs feels balanced now. It’s clear they pay attention to detail, and we were glad to have them on the project.

I’m really impressed with the job ELM did in my attic. From start to finish, the process was smooth and stress-free. They showed up on time, explained everything clearly, and made sure I was comfortable with the plan before starting. The crew was professional, efficient, and extremely tidy — they cleaned the attic thoroughly before putting in the new insulation, and they made sure the rest of the house stayed spotless. The new insulation looks great and I can already feel the difference in the temperature of the house. Highly recommend them if you’re looking for reliable and detail-oriented work.

Dale Alan Parks★★★★★7 months ago

If you are looking for a company to install insulation you won’t find anyone better than ELM. After the fire, the smoke remediation company removed all the insulation but didn’t install any new insulation. I got the number from a neighbor’s recommendation and called. They came out the next day, on time, and ready to get to work. Alex and his crew did an amazing job in the attic and crawl space. They finished sooner than expected and did a great job cleaning up. Eli, the owner, gave me o great price with no upcharges and was easy to work with. It was really a great experience!

Lei Liew★★★★★3 weeks ago

Eli with ELM Insulation is incredible. He is a trustworthy professional, honest and does a great job. We had him replace all of our attic insulation. His team was great, worked hard, and got the job done efficiently. Eli was a great communicator and even followed up afterwards to make sure everything worked out well and we were satisfied with the work. Five stars all around - I wish all contractors were as great as Eli!

I couldn’t be happier with my experience working with Hunter’s Insulation! From start to finish, Luke Hunter and his team were absolutely fantastic. The estimate I received was incredibly detailed and thorough, outlining the full scope of work so I knew exactly what to expect. Luke even included photos of the products being used, which really helped me understand what I was purchasing, a level of transparency I truly appreciated. Every step of the process was seamless. All communication and approvals were handled through my own personalized online portal, which made it so easy to stay updated and keep track of progress remotely. The crews were courteous, clean, and professional — they treated my home like it was their own. By the time they finished, everything was spotless and the work was done perfectly. Overall, I’m extremely impressed and thankful for such a smooth, professional, and friendly experience. I highly recommend Hunter’s Insulation to anyone looking for top-quality insulation work and great customer service!

Vardan Oganisyan★★★★★a year ago

I am a general contractor and I have used Hunter’s Insulation to on several jobs, including on my own personal property. Luke is very knowledgeable and he and his team can do all different types of insulation. I constructed a larger 2 story ADU in my backyard. We went with spray foam and batt insulation on the ceilings and high density batt insulation for the walls. Even in the hottest months of summer, our electric bill was only $50! If you are looking for a reliable, honest, and knowledgeable insulation contractor, Luke is your guy.

I contacted 911 Attic Insulation after reading great reviews about them, and this company exceeded my expectations in every way. The reviews I read were all true, and the service provided was outstanding from start to finish. I called the company and thoroughly discussed the attic inspection with Nick, who arrived the next day to conduct it. Nick patiently answered all my questions and provided me with a detailed quote before the end of the business day. My attic was in dire need of attention, with old insulation that needed to be replaced, debris scattered all over the attic, and rat droppings. It was also located under the lowest attic imaginable. Due to unforeseen roofing and electrical work that suddenly became a priority, the one-day job for 911 insulation turned into a two-day job, which I requested. I paid the extra fee to return at a later date so that I could have other services being worked on. Overall, I am extremely satisfied with the service provided by 911 Insulation, and I would highly recommend this company to my family and friends. Now, let's talk about Nick. Nick was my point of contact throughout the entire process, and he kept me informed every step of the way. I didn't have to contact him for anything, as he always reached out to me. I even joked around, saying that if all my home services needs had Nick as the point of contact, renovating the house would be a breeze. Thank you, Nick and team, for the excellent service!

Chip C★★★★★2 years ago

I had an attic with insulation in desperate need of repair/replacement. On top of that, we also had a rodent problem that we needed cleared up. In hindsight, we probably had the insulation and duct issues *because* of the rodent problem. After calling around for a few quotes, I found the team at 911 Attic. When they came out to give a quote, they were prompt, polite, took time to put shoe covers on, and never once tried to upsell things we didn’t need. They did mention a couple things we could add if we wanted to, but I never felt pressured. Even the way they provided the quote was more professional than I expected (itemized quote that allowed me to electronically review/approve). Then came the day of the job. It was scheduled to begin between 8 and 9, and being used to other types of companies being late (cable companies, I’m looking at you), I was expecting them closer to 9 or 10. I was happily surprised when a crew of four guys arrived at 8:15. They started putting down drop cloths and taped the job so that it reminded me of a professional house painters. They worked all the way through, with only a couple minutes off to grab some water, until the job was done. I checked out the job when everything was wrapped up and I couldn’t have been happier with the results. Not only do I have new ducts, new insulation, and fewer rodents (no rodents), I now have a place that I can use as storage that I wasn’t able to before. I would highly recommend the professionals at 911 Attic.

Quincy Janessa★★★★★a month ago

We were impressed from the very first call. Next Level Insulation provided a detailed, no-pressure consultation and clearly explained how their process differed from others. The focus on a comprehensive air seal before adding new insulation was key. The crew was professional, worked with impressive efficiency, and left the worksite immaculate. The results speak for themselves—our home is now consistently comfortable, noticeably quieter, and our AC barely runs during the day. This was a next-level service that delivered on every promise.

We brought in Tip Top Insulation after noticing our heating system was overworking. Ben came to inspect the attic and recommended a full removal and re-installation. On installation day, Ben and the crew started early, cleared out the old insulation, and sealed every gap they found. They took the time to walk me through each step, even showing where warm air had escaped. New insulation was blown in evenly, and they ensured the soffit vents stayed open for airflow. The attic was left spotless, and I appreciated how the team respected the rest of the home by protecting the floors. Within a week, we noticed the home stayed cooler much better in the evenings, and the system doesn’t cycle nearly as often.!!

John Considine★★★★★5 months ago

We asked Tip Top Insulation to update the insulation across our main home and detached garage. They used batt rolls in the walls and spray foam in the attics, and the garage now feels like part of the home. What impressed me most was how they cleaned up after themselves and gave us a full report when done. They even pointed out a small roof leak we didn’t know about. You can tell they’ve done this a hundred times.

A great group of insulation experts to work with for my attic reinsulation. They did the job perfectly, covering large areas with the right amount of insulation. They didn't cut corners. The service was also excellent, and Andrew was very easy to talk to throughout the entire project. I am glad I used them. Thank you.

I highly recommend Phoenix Insulation! I got my attic cleaned, rodent proofed, and insulated with Phoenix Insulation. Raphael provided me with a competitive quote and kindly walked me through the process, answering all my questions. On the day of, the crew arrived on time. The crew leader Jorge was very professional, friendly and accommodating. There was an accidental crack in the drywall during the process, but Raphael and Jorge made sure to get it addressed and fixed as if it never happened. When they were done, Jorge made sure to double check all the electric outlets. They did a great job with the attic insulation and I appreciated their communication.

Phoenix Insulation removed the old insulation from my attic and replaced it with new, energy-efficient material. Their pricing was very reasonable compared to other quotes I received, and the estimate they gave was exactly what I paid—no hidden costs. The team arrived on time, worked quickly, and left everything spotless. They made sure the attic was properly sealed, and I immediately noticed how much cooler and more comfortable my house felt. I’m confident my energy bills will improve as well. What I really appreciated was that the project stayed affordable without cutting corners on quality. They gave me peace of mind, a cleaner attic, and a more comfortable home. I’d definitely call them again.

I work in construction and have tried multiple insulation companies, but Phoenix Insulation truly stands out. They show up prepared, finish on schedule, and never cut corners. My clients have noticed the energy savings, which makes me look good too. Definitely a long-term partnership for my projects.

Miguel and his team were referred to us by our HVAC vendor. We had them remove and replace the insulation in our home. Miguel, Adolfo and the crew were punctual and professional throughout the project. The entire project took 3 days and they did a great job of prepping our home, covering areas to protect and keep clean, removing the old insulation, and cleaning out any remaining debris before installing the new material. Adolfo took the time to explain what would happen during each part of the process including what things I can expect from having the work done. They were also good about the cleanup work when they finished. I already notice the difference in how much the new insulation is helping block out the heat inside my home. Hard working and dedicated crew. Would highly recommend using RAM for your home insulation needs.

Miguel’s team, Hector and Alfonso did an outstanding job of insulating our attic. They came bright and early and blew in insulation as well as laid rolls of insulation throughout our space. They were professional and courteous. They even had to deal with sharing space with a painting crew that was at our house to finish up a project. Super good folks and the insulation project was priced very competitively. Give Miguel a chance to bid for your business. You won’t regret it.

Buying an older Santa Ana home meant we had a list of necessary upgrades. Insulation was a priority, but funds were tight. Smart Budget Insulation worked with us, providing a phased approach we could afford. We did the main attic first, and the improvement was so dramatic we saved up to do the garage conversion six months later. Their consistent quality and fair pricing made it all possible. They understand the real-world budgets of local homeowners.

In November 2024, we hired Top Energy to install ductless mini-splits in two studio spaces and the garage on our property. Leor was very responsive and knowledgeable, and helped us determine the location and size of the systems. Installation was one day; pricing was fair. The crew even returned to do several other handyman projects, which went well. Adding climate systems to these rooms has been a game-changer in how we use the space. Highly recommend Top Energy!

Kevin Krupitzer★★★★★2 months ago

When both of our AC units unexpectedly stopped blowing cold air Top Energy Solutions was able to get a tech out quickly to diagnose the problem. It was discovered our system had a leak in the lines running under a patio. Leor came up with a solution for us and the next day removed the old systems and installed 2 new systems. The crew was efficient, professional, and did quality work. Because of that we had Leor and his crew come back the next day and insulate the attic and install an attic fan. I couldn't be happier with the communication, efficiency, and professionalism of Leor and his crews!

Top Energy Solutions is the best contractor I have hired. Leor is responsive and professional. I acquired three quotes to have my HVAC system replaced. I accepted Leor’s quote, and the installation started, and was finished by the end of the next day - amazing. A crane was required to remove and replace the AC unit on a three story house. His installation crew was very friendly and very good natured. He beat the other quotes by more than two thousand dollars for the same equipment. Leor is a general contractor and has crews for most home repairs. I will be hiring Top Energy Solution again soon.

Frequently Asked Questions — Spray Foam Insulation in Los Angeles

These are the questions Los Angeles homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 27% typical energy savings. Compare the 46 verified Los Angeles contractors above for exact quotes.

Does spray foam insulation work well in hot dry climates like Los Angeles?▼
Yes — spray foam is highly effective in hot dry climates like Los Angeles, CA. While moisture control is less of a concern than in humid climates, the air sealing properties are critical for keeping hot desert air out and cooled air in. In extreme heat climates, an unsealed attic can reach 150°F+, dramatically increasing AC load. Spray foam in the attic can reduce attic temperatures by 30–40°F.
What is the best area of my home to insulate in Los Angeles?▼
In hot dry climates like Los Angeles, CA, the attic is typically the highest-impact area to spray foam insulate. Desert sun heats roofs to extreme temperatures, and an uninsulated attic transfers that heat directly into your living space. After the attic, crawl spaces and rim joists are the next highest-impact areas. A local contractor can perform an energy audit to identify where your home loses the most conditioned air.
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 Los Angeles, CA?▼
In Los Angeles, 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 Los Angeles costs $2,000–$6,000. Most Los Angeles 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 Los Angeles, CA?▼
When searching for a spray foam contractor in Los Angeles, 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 Los Angeles 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 Los Angeles 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.
