Lower bills, steadier temperatures
Poor attic insulation raises heating and cooling costs all year. In a Central Texas summer, heat from a sun-baked roof radiates down through a thin attic floor into your living space, and your A/C runs longer to keep up. Proper insulation slows that heat, keeps rooms more even and helps your HVAC system last longer.
Residential and commercial
We insulate homes under construction, older homes that need more, and commercial buildings such as offices, shops and rentals. For older homes we can also add insulation through existing walls, without tearing them open, to cut drafts and noise.
What's included
- A free attic check: we measure current depth across the attic and check ventilation
- A clear recommendation and fixed quote for the R-value you choose
- Knauf Insulation fiberglass products
- Depth rulers left in the attic so you can verify the result
- Full cleanup before we leave
How much insulation do you need?
About 13 inches of blown fiberglass reaches R-38, the level required for new construction in our area. If your ceiling joists are visible on the attic floor, you almost certainly need more. See blown-in fiberglass for how we install it.
Common questions
Do you blow new insulation over the old?
Usually, yes. If the existing insulation is clean and dry, we top it up. If it's dirty, smelly or damaged by pests, we vacuum it out first.
Can you insulate existing walls?
Yes, for energy savings or soundproofing. Call us to talk through your house.
How long does an install take?
Most blow-in attics are finished in 3 hours or less on average, including cleanup.
