Nestled between Plano and McKinney in the heart of Collin County, Allen has grown into one of North Texas’s most sought-after communities — with excellent schools, beautiful neighborhoods, and a rapidly expanding housing market. As a leading insulation company in Allen, TX, Excellence Home Insulation is proud to serve the homeowners and businesses that make this city thrive.
Our BPI-certified team brings more than 15 years of North Texas insulation expertise to every Allen project. We already serve Allen’s neighboring cities of Plano and McKinney, which means we know Collin County’s building styles, climate challenges, and energy efficiency demands inside and out.
From newer construction in Watters Crossing and Twin Creeks to established homes in Cottonwood Bend, every Allen home we work on gets a personalized approach — because every home is different, and the right insulation solution depends on your property’s specific needs.
Allen, TX sits in Climate Zone 3 — one of the most thermally demanding classifications in the country. Summer temperatures regularly exceed 100°F, and the humidity amplifies the heat significantly. Meanwhile, North Texas winter cold snaps can drop overnight temperatures near freezing with very little warning.
Without proper insulation, your HVAC system works far harder than it needs to. The result: higher energy bills month after month, uneven temperatures between floors and rooms, and an HVAC system that wears out years earlier than it should.
The good news? A properly insulated Allen home typically sees 20–30% reductions in heating and cooling costs — saving $600–$1,200 per year for an average-sized home. Most Allen insulation projects pay for themselves within 3–5 years through energy savings alone.
EHI serves all of Allen, TX including Watters Crossing, Twin Creeks, Cottonwood Bend, Bethany Lakes, Reed Park area, Stacy Ridge, and surrounding communities. We cover Allen zip codes: 75002 and 75013.

Your attic is where most Allen homes lose the most energy. During Allen’s long, hot summers, inadequate attic insulation allows solar heat to radiates downward into your living space, forcing your AC to work overtime. We upgrade attic insulation to the R-38 to R-60 range recommended for Collin County — keeping your home cooler and your bills lower.
Spray foam creates a seamless air and thermal barrier — the gold standard for new construction in Allen and for existing homes with significant air leakage. We apply both open-cell and closed-cell spray foam depending on your home’s specific needs and budget.
The most popular upgrade for Allen’s established neighborhoods. Blown-in insulation is fast to install, highly effective, and doesn’t require any demolition. Our crews can complete most Allen attic insulation projects in a single visit with minimal disruption.
For new construction or renovation projects in Allen where walls or floors need insulation, we install premium fiberglass batts from trusted brands like Johns Manville and CertainTeed — ensuring consistent, long-lasting performance.
Allen’s suburban layout means most homes have large attic spaces that absorb intense summer heat. A reflective radiant barrier installed in your attic can reduce attic temperatures by up to 30°F and cut cooling costs significantly — one of the best investments for any Allen homeowner.
Common signs include high energy bills, rooms that are hotter or cooler than the rest of the house, drafts near windows and doors in winter, or an HVAC system that runs almost constantly. Our free assessment will give you a clear picture of your home’s current insulation performance.
For Allen’s climate zone, the Department of Energy recommends R-38 to R-60 in attics. Many Allen homes — especially those built before 2000 — fall significantly below this range. We’ll measure exactly what you have and recommend the most effective upgrade.
Absolutely. We work throughout Allen in both newer developments and established neighborhoods. Even newer homes can benefit from insulation upgrades if air sealing was not thoroughly completed during construction.
It depends on your home’s current situation. Blown-in is ideal when adding insulation on top of existing coverage in good condition. Spray foam is best when air sealing is the primary issue or when starting fresh in a new construction project. Our assessment will clarify which approach is right for your home.
Most residential insulation projects are completed in one day. Your home stays livable throughout — we protect your belongings, clean up after ourselves, and minimize disruption to your routine.

I will be using them for a solar powered attic fan install in the near future! Pat WPosted on Martin BateTrustindex verifies that the original source of the review is Google. Great service, had them out to evaluate my attic’s insulation. The team was able to clear the old decayed insulation one day and then installed new insulation the next. Left the house nice and clean which is appreciated, I know this sort of thing can get messy. Also went the extra mile and sealed the conduit for the A/C line going into the attic. Fair price for the work, definitely recommend.Posted on Julio VaunswaTrustindex verifies that the original source of the review is Google. Manuel and his team recently sprayed the attic in my 2 story house. His team is very professional and detailed. They were very careful to not damage anything as this can be a very messy job. I had my garage insulated by another company 2 years ago. I wish I knew of Excellence back then. My garage stunk of the off gassing smell for months. In hindsight, it was probably some kind of cheap possibly chinese product the "other" company used. Now the night and day difference with Excellence Home Insulation is it was never overbearing and on day 2 was barely noticeable. Day 3 I turned on the furnace and the house did not have any weird smells. I also found out after the sale that the chemical they use has a lifetime warranty and to register it which shows the quality product Manuel uses. He also stands out that he instructs his team to go slow and do the job right the first time. My neighbor had foam installed last year and he needed them to come back days later to touch up areas that were missed. Job well done. Now it has been a week and wow the house maintains its temperature I cant even imagine how much energy savings we will have this year. Normally the second floor unit runs nonstop all summer, this will definitely save some wear and tear on this old unit. Lastly, he gives the fair price up front and does not add the "Southlake/Grapevine Tax" that most companies do thinking we all are affluent... Oh and if you are spraying a garage there is an option to add some color to the foam so you wont have to drywall over the foam and save some money. Great job and my only regret is not doing this 4 years ago as it probably would have paid for itself by now and my house would have felt consistent. Also our second floor bathroom no longer feels like a freezer when we wake up.Posted on Natalie ScottTrustindex verifies that the original source of the review is Google. It was an amazing experience to work with Manuel and his team. From start to finish, their team was professional, efficient, and detail-oriented. They didn’t just remove the old insulation flawlessly—they went above and beyond to ensure everything was done to the highest standard. The new insulation was installed perfectly, and they even took care of additional details we hadn’t expected, making the entire process seamless. Top-quality insulation services! Highly recommended!Posted on Anne OgunsonaTrustindex verifies that the original source of the review is Google. The team worked efficiently and work was done well.Posted on Chris RuizTrustindex verifies that the original source of the review is Google. I had my attic spray foamed and everything went as planned. His crew was on time and completed the job the same day. They did a great job. I had some questions and he came by a week later to go everything with me.Posted on J STrustindex verifies that the original source of the review is Google. Manuel is very responsive and professional. I was impressed with his thoroughness in completing the job and his commitment to good customer service. Thanks again for taking care of the blown in garage insulation.Posted on Juan VallesTrustindex verifies that the original source of the review is Google. Excellent service. They came by this morning to insulate the attic and walls in our garage. They're clean, efficient, and quick. Done in less time than I expected. Great work!Posted on Paul MorrisTrustindex verifies that the original source of the review is Google. Manuel’s team did a fantastic job with my attic insulation both removing the old drop insulation and adding the spray foam to the roof. I added new pipe penetrations through the roof later on and Manuel came out and added insulation around those pipes at no charge.Posted on Chris MetzgerTrustindex verifies that the original source of the review is Google. Excellent work and very professional. 2nd house we have used Excellence Home Insulation and have been 5 star experiences both times! Thank you!
