WINDOWS


Many homeowners do not realize how many benefits there are to replacing windows throughout your home. Many home builders use thin windows that provide little to no energy efficiency. You can compare this to a fireplace (windows that come with your home) versus central heating (energy efficient windows). We firmly believe in the benefits our loyal customers receive by replacing the windows in their home. We realize that it is a major investment into your home and we will provide you with many options to fit your families needs. Cotham Construction Services & Roofing takes pride in being an Austin contracting expert and can help you save money on your energy bills by replacing the windows in your home. Many of the energy providers in Central Texas offer rebates for these projects. The reasoning behind this is that although the windows can be a large investment over time the windows will pay for themselves between the rebates and energy savings.
