“You get a sense of the company you will be working with based in large part on first impressions.

We met with several companies but what struck us immediately about the representative at Lake Washington Windows & Doors was that he was very informative, listened attentively, and patient throughout the meeting. Most sales people like to talk about how good their windows are and how great their company is. The representative at Lake Washington Windows & Doors was more concerned about what we wanted and helped guide us to a product and design that fit us the best.

After deciding to go with them, their installers showed up on time and were professional, courteous, and prompt through the 3 day process. We are very pleased with our decision to choose Lake Washington Windows & Doors.”

Financial Benefits Of Home Window Replacement

Financial benefits of replacing old or leaky home windows can be significant. Some of the financial reasons that new residential windows can be a smart move:

  • Save money by cutting energy costs: old window seals and single pane glass windows allow energy to seep out, draining your wallet in the process. When your house is well insulated, your heating system won’t work as hard, and you won’t have to change the thermostat as often.
  • Write off improvements to your sold home: Many times you can reduce the capital gains tax of selling your house by upgrading and replacing windows.
  • May increase home resale value: Not all home improvements are worth the investment. Some add little to no value to the asking price of a house. Replacing windows is usually the most efficient way to add to the asking price and see a good return-on-investment (ROI).
