"The tech that came out was very friendly and knowledgeable. He explained what he was going to do, answered any questions I had, gave me time to get anything together or out of the way that I needed to, and then went to work. Price-wise, it was less than half of what other companies were wanting to treat the whole house and there are free treatments that can be scheduled after if needed. I'll be sticking with these guys."

Eifs Installers FAQs, answered by experts

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Yes, egress windows can significantly add value to a home. By making basement and attic areas safer and more livable, they allow you to market these spaces as finished living areas, which increases your property's value. Many homeowners can recover the full installation cost, with some sources citing a return on investment of around 70%. The exact value added depends on your specific home, location, and adherence to local building codes. Beyond financial value, egress windows enhance functionality by adding natural light and comfort. They are also a crucial safety feature, often mandated by building codes to serve as an emergency exit.

Yes, egress windows must meet local building codes for size and accessibility. Professional installers ensure compliance.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Depending on size, material, and labor, two windows can cost between $600 and $1,600.
