They removed all the old insulation and rodent waste thoroughly, then installed spray foam insulation that has completely transformed the space. Afterward, I sealed the attic, which will help lower our energy bills and keep the temperature stable. What impressed me most was how clean and non-toxic the process was, they left the air fresh and the entire area spotless.

I want to thank Wayne and Angel for their quick response in helping us out. We were doing a construction project on our student center in San Marcos Tx. and found out that we needed to have a dumpster on site before we could proceed. I made a call to Wayne with dumpstersaurus dumpsters and explained my situation. He was quick to respond and had me a dumpster at the construction site the same day saving us from having the project shut down. Not only did he get it there the same day but the price was very fair and service was very friendly. In today’s business world it was very refreshing to have a company that was trustworthy, quick to respond with same day friendly service, and a very fair price, If you are needing a dumpster I highly recommend dumptersarus dumpsters.

Transforming Energy Efficiency Through Building Science
True home comfort requires more than just adding material; it requires a comprehensive understanding of building science and air infiltration. Many homes in the Killeen area suffer from “stack effect,” where conditioned air escapes through the attic while drawing in dust, allergens, and humidity from crawl spaces or wall cavities. By addressing the root cause of energy loss, air leakage, we create a sealed, conditioned environment that protects your family from outdoor pollutants and stabilizes interior temperatures year-round. Our team evaluates your entire structure to prescribe the most effective thermal barrier solution.

Frequently Asked Questions (Killeen & Central TX)
How does spray foam insulation handle the extreme humidity in Killeen?
Spray foam is excellent for humidity control because it acts as an air barrier. Sealing air leaks prevents moist outdoor air from entering your home and condensing within wall cavities or attics. Closed-cell foam, in particular, acts as a vapor retarder, providing an extra layer of protection against the humid Central Texas climate.
Will spray foam help reduce noise from Fort Cavazos activities?
Yes, insulation significantly improves acoustic dampening. Open-cell spray foam is particularly effective at absorbing sound waves. Many Killeen residents find that spray foam insulation helps muffle the noise of helicopters, artillery training, and general street traffic, creating a quieter interior environment.
Is it necessary to remove my old insulation before adding spray foam?
In most cases, yes. To apply spray foam effectively, it needs to adhere directly to the substrate (wood studs or roof deck). Removing old, dusty, or pest-ridden fiberglass allows us to inspect the structure for damage, seal all air leaks properly, and ensure the foam cures correctly without interference from debris.
How long does spray foam insulation last compared to fiberglass?
Spray foam is a durable, long-term solution that does not settle, sag, or degrade over time like traditional fiberglass or cellulose. Once cured, it remains in place indefinitely. While conventional materials may need topping up or replacement every 15-20 years, spray foam is generally considered a lifetime product for the building.
Does spray foam insulation really lower HVAC usage?
Absolutely. By sealing the “building envelope,” spray foam prevents conditioned air from leaking out and hot air from leaking in. This means your HVAC system doesn’t have to work as hard or run as long to maintain your desired temperature. This reduced runtime extends the life of your equipment and lowers energy consumption.
