Just like many other components of your house, windows eventually need to be replaced. If you’ve been thinking about replacing your windows, our expert staff is ready to come out and give you a free consultation to see if replacing some or all of your windows is the right move for your home.

Save Money on Energy Costs

Modern windows are much more efficient at keeping your house insulated and preventing the outdoor elements from getting indoors. Older windows can be prone to letting in more air and moisture to your home, which affects your overall energy costs. Think of replacing old windows with new ones as a long term investment in your home’s energy efficiency; it’ll end up saving you a great deal of money on your heating and cooling bill over time.

“Wonderful! I had a great customer experience dealing with Diana. She was thorough, knowledgeable, and very descriptive in the estimates. She would always be open and willing to make any change I wanted and send back the updated estimate. The estimate had all the explanations to the T for every window. Overall, I am very happy with the Milgard windows that Diana and her team at Windows Only installed at my home…”

“Windows Only was fantastic. We worked with Rod (sales) and Gordon (installation), and both made things so easy for us. The price was below another local company, and they did a great job. Rod is especially knowledgeable, helpful, and there for you every step of the way, and after. Rod goes above and beyond to make sure you are 100% satisfied. I will recommend Windows Only to anyone needing windows.”

“Ryan went above and beyond. Time constraints in a real estate deal can be difficult to meet but when there was a schedule conflict Ryan made sure and kept his original commitment. We were able to close on time. I can’t tell you how much we appreciated his great attitude and professionalism. The window looks great too! I can highly recommend Ryan and Windows Only.”
