Insulation for Leon Valley homes

Why Leon Valley attics need attention.

Leon Valley is a small city surrounded by San Antonio on the northwest side, with many single-story homes on established streets. In homes of this age, original insulation has often settled to just a few inches and may be mixed with dust, debris or droppings.

We recommend removing old insulation when it is contaminated or badly compressed. After removal we clean and sanitize the attic, seal air leaks and install new insulation, then walk you through photos of the finished attic.

Questions

Attic insulation in Leon Valley: FAQ

My attic insulation looks gray and flat. Is that normal?

Gray, flattened insulation is usually old, dusty and compressed. It does not insulate the way it should, and replacing it often makes a noticeable difference.

Do you serve all of Leon Valley?

Yes. We serve homes throughout Leon Valley and the surrounding San Antonio neighborhoods.

Is the attic inspection really free?

Yes. We inspect the attic, show you photos of what we find and give you a written quote. There is no obligation to book.

Do you always remove the old insulation?

No. When the old insulation is contaminated, wet or badly compressed, we remove it, clean and sanitize the attic and seal air leaks first. If it is in good shape, we will tell you whether adding new insulation on top is enough.
