Blown-in fiberglass insulation in Waco

Drafty doors, cracked windows and thin attic insulation let your conditioned air escape. Blown-in fiberglass is the most cost-effective fix for most Central Texas homes, and the average install takes 3 hours or less.

Please note: we do not provide spray foam insulation.

Why blown-in fiberglass?

Blown-in fiberglass fills the attic floor evenly, works its way around wiring, ducts and framing, and doesn't settle or break down the way paper-based products can. It's non-combustible, resists moisture and pests, and can be blown right over clean existing insulation.

Economic benefits

A well-insulated attic holds your indoor temperature steady, so your heating and cooling systems cycle less often. Customers regularly tell us they notice the difference on their next electric bill.

Stop wasting energy

Heating and cooling a home without enough insulation means paying to condition air that leaks out through the ceiling. Bringing your attic up to R-38 stops most of that loss. We use proven Knauf Insulation products.

In and out in 3 hours or less

Our average blow-in install takes 3 hours or less from setup to cleanup, so most homeowners have their attic finished before lunch or by mid-afternoon. You don't have to clear out the house or plan around a multi-day project.

What to expect on install day

  • We protect the area around your attic access
  • Insulation is blown in from a hose run from our truck, so there's little mess inside
  • Depth rulers are placed so you can see the final depth
  • Most attics are done in 3 hours or less

Common questions

How long does blown-in insulation take?

Our average blow-in install takes 3 hours or less, including setup and cleanup. Larger or harder-to-reach attics can take a little longer, and we'll tell you upfront.

Do you offer spray foam?

No. We don't provide spray foam insulation. Blown-in fiberglass delivers excellent results for most attics at a much lower cost, with a faster payback.

What R-value do you recommend?

R-38 (about 13 inches) is the code level for new homes in our area. We can go higher if you want extra protection.

Can you blow over my existing insulation?

Yes, if it's clean and dry. If not, we remove it first.

He provided a fair and reasonable quote, clearly explained the work that needed to be done, and delivered exactly what he promised. The installation was fast, clean, and precise. The crew was professional, paid attention to the details, and left everything clean when they were finished. It’s refreshing to work with a company that provides quality workmanship, fair pricing, and great customer service without trying to oversell you.

He arrived on time, was very professional and explained everything to us in detail. … There were no surprises and I’ll add they were meticulous in cleaning up once finished. We’re also seeing less electrical usage this summer than last which is what we were hoping we’d see. He also did my dad’s house and my cousin’s house based on our experience.

When the owner came to my house he provided me with text message updates for his arrival time. Very nice. I was also given a written estimate and the price did not change. The day of the install this company was on time, all employees clean cut, very friendly and never stopped once during the 3.5 hours they were on property. All trash was picked up clean before they departed. … Think Home Insulation provided me with a number of pictures and videos showing the overall attic and the thickness of the insulation with depth rulers that are still in place for the next owner down the road.
