Our home needed the attic insulation replaced, so I reached out to Insulation Commandos. Martha and her team were incredibly professional, honest and considerate. They are people with high integrity !! I highly recommend using this company for all your attic insulation needs. Many homes are under insulated and you need to give them a call.

Hesam Movahed★★★★★a month ago

Had a great experience working with them doing attic insulation! They did a great job, from showing up for a quote all the way to getting the job done with great quality at an exceptionally great price! The best part is that they offer something nobody else does: blown rockwool. My suggestion to everyone: ask ChatGPT (or other AIs) for a comparison table along with pros and cons for rockwool vs. fiberglass vs. cellulose. Looking for quality great price longevity durability performance, insulation commandos is the way to go

Karl Jay★★★★★2 weeks ago

The insulation commandos showed up on time, had well maintained equipment, put down protective barriers on woodwork, and installed 1 ft of insulation in the Attic. They also helped remove some boxes that needed to come down from the attic and when they were done they cleaned up everything including the garage. The crew all had uniforms and were extremely courteous. He was a great experience!

Beni Raz★★★★★2 weeks ago

Insulation First is amazing! They took out the old insulation, sealed up all the leaks, and sprayed new insulation! all without me even having to be there. They made the whole process super easy and stress-free, and they documented everything so I could see exactly what was done. When I came home, the job was finished perfectly. Couldn’t ask for better service they’re truly #1!

Matan Nigreker★★★★★3 months ago

Jimothy is a very nice, clearly honest, and knowledgable guy when it comes to insulation and ventilation. He came out to get a good look and take measurements of our existing insulation and didn’t charge. His team is easy to work with and they get a good job done very quickly! Highly recommend!!

Penguin was great to work with! Alex jumped on a FaceTime call with me so I could show him my project. He gave me an accurate and fair quote over the phone. Johnny showed up to the job on time and quickly started working on my project. He took time to answer my questions and made sure he understood everything that needed to be done. The work was high quality and finished on time the same day. They even hung around and chatted with me for a while and offered to help me take down my Halloween decorations. Overall my experience was excellent and I definitely recommend Penguin for your insulation needs.

John Graves★★★★★5 months ago

Was very very pleased with the service that they did. Alex came out inspected the house told me what we needed. We had a very good price compared to others. His crew worked very hard and did an excellent job. I would highly recommend him. Our house is a lot cooler now that he re-insulated it for us.

Aaron Ausherman★★★★★4 months ago

Top notch. Out of any business deal, I want three things: hard work, integrity, care. Alex is amazing and a deserved business owner in DFW. He did fast work, quality work, and all for a great price. Alex immediately came back to fix the powered fan they installed 3 months ago. Immediately got back to me after doing the work 3 months ago!! Find that somewhere else. If you don’t go with Alex and Penguin Insulation for your next cost savings project, you’ll miss a great experience and outcome.

From start to finish, the project went well. Jody came out to give a quote and was thorough and gave recommendations without being pushy. Once the quote was confirmed, it was scheduled within two days. The crew arrived and handled the job quickly and with no issues. They were kind and handled business. We opted for the additional solar fans with the project. The roofing crew arrived promptly at the provided time, they worked well alongside the insulation crew and were also wrapped up quickly. Great, smooth experience on a project we’ve needed done.

I used this company to add some blown in insulation in my attic. Their team that came out were friendly, focused, and did a great job getting me to R-38. I look forward to lower utility bills.

Tony★★★★★5 months ago

Kevin and his team were great to work with. We have a 75 year old house - One unexpected benefit is that they completely vacuum out the old insulation and go back to the studs - and then seal with foam and then blow in the new. Maybe it's in my head but it was 95 out yesterday and the house was noticeably cooler. Great job.

Had this company spray foam my attic and it made a huge difference in my homes heating & cooling, I only wish have done it sooner. Wonderful and professional company.

Ebony Arnold★★★★★3 years ago

One of the duct work pipes in our attic was uninsulated and we fixed it by getting insulation sprayed on it. The technician who came out to do the job, Joshua, is seriously the best. He really took his time to make sure that delicate and difficult areas were handled with agility and care. I can't recommend this company enough. I'm planning on using A+ Spray Foam Insulation Inc for my future spraying foam projects and will recommend them to anyone who's in need of the same.

Latasha Ray★★★★★3 years ago

It was a pleasure to work with A+ Spray Foam Insulation Inc. I really like how dedicated they are, from giving me an estimate to installing it. They got there earlier than expected and finished when they said they would. This is a very reliable company that does a great job and has great service.

Called for an estimate. Was told he would call on the weekend and come by. No call. No show. No response to message left after. Apparently Amarillo insulation companies do not need any business as this guy is not the only one to do this. Ugh.

Frequently Asked Questions — Spray Foam Insulation in Lewisville

These are the questions Lewisville 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 10 verified Lewisville contractors above for exact quotes.

Does spray foam insulation work well in hot dry climates like Lewisville?▼
Yes — spray foam is highly effective in hot dry climates like Lewisville, TX. 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 Lewisville?▼
In hot dry climates like Lewisville, TX, 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 Lewisville, TX?▼
In Lewisville, TX 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 Lewisville costs $2,000–$6,000. Most Lewisville 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 Lewisville, TX?▼
When searching for a spray foam contractor in Lewisville, TX, 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 Lewisville 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 Lewisville 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.
