Allen has grown into one of Collin County’s most sought-after addresses along the US-75 corridor — and with that growth comes a mix of established 1990s-2000s neighborhoods and a steady wave of new construction.

From established properties near Twin Creeks and Montgomery Farm to newer builds off US-75, our BPI-certified team understands that a home built in 1998 needs a different spray foam approach than one built last year. We don’t believe in cookie-cutter solutions — every Allen home gets a free, thorough assessment before we recommend a single product.

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!
