Insulation Contractor · Fayetteville, AR

Insulation contractor in Fayetteville, AR

WeatherGuard serves Fayetteville with spray foam, blown-in fiberglass, and crawl space encapsulation. Fayetteville has some of the oldest housing stock in Northwest Arkansas, which makes it one of the places where an insulation upgrade shows up fastest on a utility bill. We have been doing this work as a family-owned insulation company since 1996. Estimates are free, in person, and in writing.

Insulating Fayetteville homes

Fayetteville has a high concentration of genuinely old homes, including entire historic districts where houses predate insulation code altogether. Many were insulated retroactively, often decades ago and often only in the attic, and a fair number sit over vented crawl spaces on bare ground. The combination of an under-insulated attic plane and a damp crawl space is the single most common condition we find in the older parts of this city, and it is also the pair that responds most dramatically to being fixed. Newer construction south and east of town presents the more typical bonus room and vaulted ceiling issues instead.

Fayetteville insulation questions

What homeowners ask before we start.

Do older Fayetteville homes need different insulation?
Often yes. Many Fayetteville homes predate insulation code, so we frequently find a thin attic plane over a vented crawl space. That pairing needs both addressed to actually work. The free inspection tells you which parts of your house are the priority and which can wait.
How much does insulation cost in Fayetteville?
The honest answer is that it depends on square footage, material, and access, which vary more in Fayetteville than anywhere else we work because the housing stock spans a century. An older home near downtown and a new build south of town are different jobs. Every quote is free, in person, and in writing.
Will new insulation actually lower my energy bill?
In most under-insulated NWA homes, yes, and noticeably. The Department of Energy estimates air sealing plus insulation saves an average of 15 percent on heating and cooling. Homes built before modern code often save more. We will tell you honestly if your insulation is already adequate.
How long does installation take?
Most blown-in attic jobs are done in one day. Spray foam projects typically run one to two days. Crawl space encapsulation is usually two to three days depending on size and moisture conditions. You get a firm timeline with your written estimate.

Your house is leaking money. We have been fixing that since 1996.
