Why Is There Moisture Inside My Window?

LAS - Example of a broken window seal — Window Moisture

Windows add an aesthetic component to your home in many ways, but functionality is important too. Windows can, and should, be utilized to further insulate the home, thereby maximizing energy efficiency. Moisture and discoloration inside your window glass is usually a result of a broken seal. While seals can be repaired, the fix may only be temporary. Under humid conditions, condensation shows up on the interior window surface. There are many reasons for condensation to occur and many ways to limit humidity in the home. Moisture inside the window, and even on the windows, indicates that insulation may be compromised. Window maintenance is essential in reducing humidity and condensation, thereby increasing the home’s energy efficiency. Weather stripping may be faulty or have become worn. The window’s ability to prevent air leakage is only as good as it’s installation.

If you’re having moisture issues with your single-pane windows, it may be time to consider replacing them with double-pane windows. There is no guarantee against condensation, but it should drastically reduce the risk of excessive humidity in the home. The median comfort range of indoor relative humidity is between 35% and 45%. Double pane windows will typically allow about 37% relative indoor humidity to exist without condensation versus just 12% in single-pane windows.

Julia,
On behalf of Lighthouse Louisiana (formerly The Lighthouse for the Blind), please convey my thanks once again to your coworkers for supporting our summer camp for children who are blind. It is a rare thing to see a corporate family like yours, where people get together and give from their own hard-earned paychecks to local groups that are doing good work in the community. As donors, sometimes it’s hard to know what donations to organizations we care about are actually being used for. We consider LAS an important investor in our work, and we cannot thank you enough for helping us serve our clients.

Thank you,

We just finished getting new windows from LAS and I can’t be any happier. From start to finish, this job was done professionally. The salesman, Garrett, came to the house on time and explained the windows and the process and answered any questions that we had at the time. He indicated the person who would do the measurements would call and set up an appointment within two weeks and the the windows would be built and installed in about 5 weeks. Well, the job – from the initial estimate to complete install – was three weeks. The installed that completed the job did an excellent job of install, caulking and cleanup. We can’t give them a higher rating. The most amazing thing so far is the look and how much it has cut down on outside noise. I highly recommend LAS and since they are local, from repairs to employing people, we keep it right here at home. We are very satisfied customers.
