Legacy Insulation

Legacy Insulation handles insulation projects across Los Angeles. The company focuses on attic upgrades, wall cavities, crawl spaces, and garage builds using spray foam, blown cellulose, and dense-pack methods. They also run energy audits that check air leaks, ventilation, and existing coverage levels. Estimators like Arthur and Damon visit sites first, while project leads such as Taylor and Russell coordinate crews that include Joe, Manuel, and Emmanuel. Reviewers note the firm keeps its own installers rather than subcontracting, and the same names appear across multiple jobs for consistency in attic cleaning, rodent sealing, and duct work.

Customers call for help with older homes that lack wall insulation or have uneven attic coverage, which makes rooms hard to keep comfortable in warm weather. One project involved removing wet insulation after rain damage, treating the area, and adding fresh material to restore proper R-value. Another addressed rodent entry points by sanitizing the attic, installing mesh barriers, and replacing damaged ducts alongside new insulation. Garage builds with second-story space often need spray foam for air sealing and coverage in tight spots, while full-home jobs combine attic and crawl-space work to cut energy loss. Reviewers mention the crews finish on schedule, protect floors and trim, and leave the house clean.

The company responds fast to calls, with Arthur often answering directly and sending detailed estimates the same day. Pricing comes in lower than other bids without hidden fees, and crews arrive on time even for special scheduling requests. They explain options in plain terms during inspections that cover attics to crawl spaces, then handle the full scope from removal to final install in one or two days. Service stays within the Los Angeles area, and reviewers highlight steady communication by phone or text plus careful attention to existing structures during wall and attic work.

“We were planning to insulate a new garage with a second-story area, so I spent a lot of time learning about spray foam insulation and comparing estimates from several insulation contractors. Arthur was the first person to come out, and he explained the insulation system clearly and in simple terms. He was very knowledgeable about spray foam, energy efficiency, coverage levels, and what would work best for the garage. I also appreciated how quickly the estimate was sent over compared with other contractors I contacted. After reviewing several bids, I chose this insulation contractor because of the strong reviews, fair pricing, and the overall insulation value offered. Some of the other estimates came in much higher, while this company offered spray foam insulation that went beyond basic code requirements and provided better thermal performance. We ran into a few scheduling delays because of other work being done in the garage beforehand, but Arthur was patient and flexible throughout the process. He helped get the insulation job scheduled quickly once the space was ready, which made everything much easier. Taylor and the crew did an excellent job on installation day. They made s”

“I’m very glad I was referred to Legacy Insulation for insulation and home energy improvement work. I first reached out for a full home energy inspection, and the team was very helpful in explaining the process, possible rebate options, and how the upgrade plan would work from start to finish. Their staff was professional, easy to talk to, and quick to answer questions. The inspection team arrived on time and checked the house carefully from attic to crawlspace, looking at insulation levels, air leaks, ventilation, and overall energy performance. They took time to explain what they found and helped me understand which insulation contractor services would make the biggest difference for comfort and efficiency in my home in Commerce. They worked with me to build a clear plan for better attic insulation, air sealing, and ventilation improvements. I received a detailed, itemized proposal with each part of the job explained in simple terms, and they were flexible about letting me choose which upgrades to do now and which ones to wait on. That made the whole process feel honest, practical, and pressure free. Once the work started, the crew was professional, friendly, and very thorough. Ru”

“We got three bids for insulation work on our older home, and this insulation contractor came in at less than half the price of the other two. We wondered if there was a catch, so we checked references, and they were excellent. That gave us confidence to move ahead. They started with a detailed home energy audit to find where our insulation and air sealing needed the most attention. The inspection was much more thorough than a past audit we had done, and it clearly showed the problem areas in the walls and attic. The crew arrived on time for the wall insulation work, and joe, emmanuel, and manuel were professional, friendly, and easy to work with. They worked steadily for two days, handled the re-insulation carefully, and cleaned up everything when the job was done. During the project, a wire was accidentally loosened, but they came back right away and took care of it quickly, which showed real accountability and good service. We are now moving into the next phase to upgrade the attic insulation, improve energy efficiency, and help the house stay more comfortable during hot Commerce weather. They also helped explain available rebates and recommended the most cost-effective insulatio”

“Arthur, Taylor, and Damon did a great job with our insulation project. We needed more attic insulation and air sealing to help improve comfort and energy efficiency, and the crew handled everything smoothly from start to finish. They were kind enough to schedule a special appointment on a day that worked best for me, which I really appreciated. The whole team arrived on time, explained the insulation process clearly, and made the job easy to understand. Arthur even went up into the attic and carefully worked through the tight spaces to make sure the blown-in cellulose insulation was installed evenly and that all the problem areas were properly covered. Their attention to detail really stood out, and the work looks clean and professional. I was also happy they recommended the drill and fill approach because it made the insulation upgrade less disruptive for us and left a much cleaner finish. Overall, the service was efficient, helpful, and high quality, and I would gladly use this insulation contractor again.”

“I got four estimates for adding insulation in my attic and first-floor crawl space, including one from a big home improvement store. This insulation contractor offered the best price by far, and it was also clearly the best overall service. Arthur answered the phone when I called, and every time I reached out, he replied quickly and politely. He sent a detailed estimate that clearly explained the insulation work, materials, and scope of the job. The crew arrived as scheduled, completed the attic and crawl space insulation work efficiently, and cleaned everything up before leaving. The whole process went smoothly from start to finish. After a few days, I noticed some recessed lights flickering and wondered if my whole house fan was not moving as much air. I contacted Arthur, and he immediately arranged a follow-up visit to check everything. The technician showed up right on time, fixed the light issue, and carefully inspected the attic installation. He even climbed into the attic and took photos to explain that the whole house fan was actually working properly. It turned out the home just sounded much quieter after the new insulation was installed, which made me think the fan was pu”

“I recently had my attic insulation upgraded by Legacy Insulation, and the whole experience was excellent from beginning to end. russell was very thorough and responsive throughout the process, answering questions and explaining the insulation work clearly. The installers, joe and manuel, were professional, careful, and efficient the entire time. They protected the work areas well, kept dust and debris under control, and cleaned up everything before leaving. I’ve had other contractors in my home before who left a mess or were rough around walls and trim, but this crew was respectful and did quality work. The attic now feels properly sealed and insulated, and the house is more comfortable during hot weather. joe and manuel really went above and beyond, and i appreciated how smooth and well-organized the whole job was.”

“Legacy Insulation did an excellent job cleaning out our old attic blown insulation, rodent proofing, air sealing, sanitizing, and installing new R-38 cellulose. damon the estimator was easy to talk to, gave helpful attic insulation advice, and sent the proposal very quickly after the inspection. taylor, the project manager, made scheduling simple and kept everything moving smoothly. The 4 person crew arrived ready to work, stayed organized, explained the insulation scope clearly, and handled the attic restoration with real care. They completed the full attic insulation removal and install in just one day, which was impressive for the size of the space. Cleanup was thorough, the house was left neat, and everything felt back to normal by the end of the day. manuel also made sure we received detailed before and after photos with the invoice, which helped us see the quality of the air sealing and cellulose insulation work. i really appreciated how efficient, professional, and straightforward the whole process was, and we could already notice the home felt more comfortable in the warmer weather.”

“We recently had insulation work done on our 2-story home, and we are very happy with the results. Our older house had little to no insulation in the wall cavities, which was making the home less energy efficient and harder to keep comfortable during warm California weather. During the free consultation, Emmanuel clearly explained where our home was losing energy and went over the best insulation contractor options for improving overall efficiency. He gave us a detailed proposal the same day, which made the process easy to understand and move forward with. Emmanuel was responsive, thorough, and helpful from the beginning. We chose dense-pack insulation for the exterior walls along with duct sealing using the Aeroseal process. Russell, Damon, and Emmanuel handled the installation with professionalism and care. They arrived on time, worked efficiently, kept everything organized, and answered our questions in a simple and respectful way. It was clear they knew their insulation and air sealing work well. The whole experience was smooth from start to finish. The team improved our home's comfort, helped reduce wasted air through the ducts, and made the house feel better insulated overall.”

“We highly recommend this insulation contractor. They installed insulation in our attic and crawl space, and the whole project turned out great. The first day of the two-day job was delayed because of our own scheduling issue, but they came back the next day and worked hard to finish everything efficiently in one visit. Taylor and the crew were excellent—polite, helpful, and patient with all my questions. They were also very considerate around our goofy dog and treated our home with care. They cleaned up well when the insulation work was done, and the house was left neat and tidy. We would gladly use this insulation team again and would be happy to request the same crew for future attic insulation or energy-efficiency work.”

“The insulation contractor did a solid job overall and helped us understand what was affecting the temperature difference near our baby’s room. After looking over the attic insulation and airflow, they explained that the issue could also be tied to wall insulation and how the new build was put together, not just the blown-in insulation area. Taylor was polite, listened to our concerns, and made sure the insulation work met code. In a warm climate like California, keeping rooms comfortable and improving energy efficiency really matters, and their team took time to discuss insulation coverage, attic performance, and ways to help the home stay more even in temperature. They were professional, helpful, and clearly cared about getting the insulation situation checked the right way. I would recommend them to anyone needing insulation contractor services.”

“Exceptional attic insulation service. I recently worked with Legacy Insulation and had a great experience. From the first visit to the final cleanup, the crew showed real professionalism, strong insulation knowledge, and a clear focus on improving my home’s energy efficiency and indoor comfort. The team arrived on time, fully prepared, and ready to inspect the attic carefully. Russell and Taylor explained the insulation process in simple terms, reviewed the condition of the existing attic space, and went over the best insulation options for my home’s needs. They answered questions clearly and helped me understand how proper attic insulation, air sealing, and coverage can help the house stay more comfortable during the hot Commerce weather while also helping reduce energy loss. What stood out most was their attention to detail and their commitment to doing the job right. They did a thorough attic assessment, recommended a tailored insulation solution, and made the whole service feel smooth and dependable. Their workmanship and customer care left a strong impression, and I would highly recommend them for attic insulation work.”

“We had a very good experience with this insulation contractor. They upgraded our attic insulation and sealed a large crawl space, which has already helped the house feel more comfortable in the warmer California weather. Joe, the insulation specialist, was very knowledgeable, easy to work with, and helpful through the entire process. The crew clearly knew their insulation work, explained each step, and made sure we understood what was being done and why it mattered for energy efficiency and indoor comfort. They were careful, professional, and focused on doing the job the right way. There was one small issue during the project, but it was handled quickly and with full attention from management, which showed they really stand behind their work. I would definitely recommend this insulation company and the whole team.”

“Legacy Insulation came out fast after rain got into my vents and caused water in the attic. They removed the wet insulation, treated the area with a microbial spray, and blew in fresh attic insulation to restore proper coverage. i feel much better now knowing the attic is dry, sealed up, and better protected from mold issues. The price was fair, and arthur explained they were not charging inflated emergency rates. manuel and the crew were friendly, professional, and kept the work area clean. A few days later, the insurance adjuster looked over the job and said they did great work and even added extra insulation for better energy efficiency. joe also took time to explain the insulation process, and i appreciated how thorough and honest the whole team was.”

“I built a new RV coach house and decided to hire an insulation contractor instead of dealing with extra prep work on the space. I am very glad I did. Manuel and the crew were skilled, professional, and clearly understood spray foam insulation and air sealing. The insulation product is high quality, and the whole job was completed the right way and on schedule. Emmanuel also came out to check the work and make sure everything was done properly. I highly recommend this insulation company if you want top quality insulation for an RV building, garage, or similar structure. After the install, the coach house held a steady indoor temperature overnight, which really showed how well the insulation was working. I am going to love the added comfort and energy efficiency.”

“we have relied on this insulation contractor for all of our insulation needs for many years, including sound deadening foam for interior walls. if you're looking for high-quality work at a fair price, this is the team to call. they specialize in spray foam, sound control, batt insulation, and energy-efficiency upgrades that help homes and buildings stay cooler and more comfortable in warm weather. Unlike many insulation companies that subcontract the labor, this company uses its own dedicated crew to handle the job from start to finish. joe and the team showed strong attention to detail, clean workmanship, and a real focus on doing the install right without cutting corners. they took time to explain the insulation options, helped us choose the best fit for our space, and delivered a top-notch result with better comfort and noise reduction throughout the property.”

“A friend of mine had attic cleaning, new insulation, and duct repair done and kept talking about how great the insulation crew was, so I asked for the number because I wanted to have my older home checked out too. I called Joe, and he got back to me very fast and set up a time for an attic inspection and estimate. When he arrived, we walked through the house and talked about the attic, insulation levels, duct condition, ventilation, and even some homeowner insurance basics. He gave very helpful advice and had a calm, honest way about him that made me feel comfortable having him in my home. He climbed up to inspect the attic, looked over everything carefully, checked what was there and what was missing, and took photos so he could explain it clearly. After the inspection, he told me I did not need any insulation or duct work done right now because my attic insulation and ducting were still in solid shape. I really appreciated that honesty. Instead of trying to sell me something I did not need, he explained what signs to watch for over time, how attic insulation can affect comfort and energy efficiency in a Commerce home, and when it might make sense to plan for future work. He also ”

“I heard about this insulation contractor through my brother-in-law, who works in construction. When we built our new home, their crew handled the insulation install, and the whole experience was excellent. They did a very thorough job with the spray foam insulation, and when they finished, the house was even cleaner than when they arrived. After seeing the quality of their insulation work at our home, I also hired them for a project at my business, and the results were just as impressive. The team was professional, efficient, and easy to work with from start to finish. The spray foam really helped improve energy efficiency and made it easier for the HVAC system to keep the space comfortable during the warm Commerce weather. I would definitely recommend this insulation contractor to anyone wanting better comfort, cleaner work, and dependable results.”

“I recently used spray foam for a home insulation upgrade, and I’m very impressed with the results. The application was simple, and the foam was easy to direct into small gaps, wall cavities, and other hard-to-reach areas. It expanded fast and created a solid, continuous insulation barrier that helped seal air leaks around the home. The insulation performance has been excellent. It has made the house feel more comfortable during hot Commerce days and cooler evenings, and I noticed better indoor temperature control almost right away. The foam also seems durable and well-suited for long-term use, with good resistance to moisture and conditions that can affect insulation over time. I used it in walls, ceilings, and floors, and each area turned out very well. The cleanup was minimal, the overall process was smooth, and the finished work looked professional. Since having this insulation work done, I’ve noticed improved comfort and better energy efficiency. If you need an insulation contractor or a reliable spray foam insulation solution, this was a great choice and well worth the cost.”

“Taylor completed a full inspection of our attic and arranged for the insulation crew to handle the work. We had a serious rodent problem in the attic, and the team did an excellent job from start to finish. Manuel and Russell cleaned, sanitized, and deodorized the entire attic space, sealed entry points with mesh, and set traps that worked well. They also removed the old insulation and worn-out ductwork, then installed new insulation and durable aluminum flex ducts to help protect the system from future rodent damage. The crew was friendly, professional, and clearly skilled in attic cleanup, insulation replacement, and duct work. They worked efficiently, paid attention to detail, and left the attic cleaner, safer, and in much better condition than before. We are very grateful for the quality service and strong teamwork.”
