Jimothy shared some great information and explained our options with the pros/cons of each option along with the costs. No high pressure sales at all. Cristian and Kenneth were professional, communicated well about their timing, showed up on time, and truly seemed glad to be here doing a job I was not willing to do myself!! They were very helpful connecting some exhaust fan vents to the roof vents and worked quickly blowing in the insulation. They also cleaned up the minimal mess they made. Good job guys. I can’t wait for this next year to compare my electric bill. Give Attic Insulation DFW a call. You’ll be glad you did!!

Ron Matthews★★★★★a month ago

Excellent company I used for spray foam on my walls and blown in insulation in the attic. As the owner of a golf construction company I routinely deal with sub contractors on a daily basis. From my first call to shaking hands with the employees who completed the working they were extremely professional & polite. The work was done better than expected and they cleaned up when finished. Highly recommend!

Morgan★★★★★2 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!!

Great service and the techs were very punctual. Prior to using them they gave me options that worked best for my needs, not just selling the most expensive option. Never had the feeling of buyer remorse. Definitely recommend.

Kevin was especially helpful and friendly throughout-it was clear he genuinely cared about providing the best service possible. The quality of their spray foam work is outstanding, and it's clear they take pride in what they do.

Rick Scott★★★★★a year ago

Job was done very professionally and in a timely manner. Attention to detail is what separates a great installer from and average one and that is what makes Pristine Energy Solutions a great installer. The small details make all of the difference to me. Would definitely use again.

I have known Chris Roberts and Paul Davis for several years. They have completed jobs on five different houses I own (rentals) as well as my place of business. Their work is flawless. They are very willing to work with my schedule and were excellent at communicating with me about how best to serve my specific needs. Their work crews were on time and left the job sites in tip-top condition. In fact, I will most definitely use them again and I highly recommend Assured for any and all insulating needs you have. I am a very satisfied repeat customer! Glenn Ballard Flint, TX

Joseph Lucas★★★★★a year ago

We had our attic spray foamed a few months ago with this company. Edgar and his crew put in open cell. We wanted to wait to do a review so that we could see how it went after the work was done. I must say those guys did an amazing job. It took them a while for clean out, since we had a lot of old insulation covered by another layer of newer insulation, so it was quite a job just for that. This was in the summer heat, mind you, but they got the cleanout and the spray foam done in about a day and a half, which was faster than I thought. Their communication wasn't the best, since I don't think they spoke much English, but it didn't bother us too much. My wife was about to give them a tip, but they left in such a hurry after it was done, she didn't get a chance to. I guess they must be pretty busy. I would recommend them to anyone, and I have done so since ours was done. Assured Insulation has certainly served us well and helped us to lower our electric bill. Keep up the good work.

Caroline Guinan★★★★★2 years ago

I had a great experience working with Assured Insulating. I appreciate how well they communicated with me, and they always showed up when they said they would. They got the job done quickly and on time. There was never any confusion on pricing, I always got an invoice in a timely manner. Richard made the whole process a breeze from start to finish.

Frequently Asked Questions — Spray Foam Insulation in Rockwall

These are the questions Rockwall 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 7 verified Rockwall contractors above for exact quotes.

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