Signs of a Bad Window Installation

You’ll only have to update your windows once or twice in a lifetime, so make sure to choose the best windows and contractor for your project. Poorly installed windows can compromise your property’s energy efficiency and security.

In this article, Renewal by Andersen of Kansas City enumerates the signs that you had a bad window installation job.


Air drafts indicate that a gap exists between the sill and the frame. The imbalanced pressure on both sides of the window will let air from the outside enter your property, pushing your HVAC to work harder to achieve comfortable indoor temperatures. If your energy bills have increased or you feel chilly when you’re next to a window, you probably have air drafts that need sealing.

Sill and Frame Gaps

Professional window installers ensure zero gaps between sills and frames. They ensure the correct measurements so that the windows fit snugly in the opening. You can tell if the window installers did their job properly by turning off the lights at nighttime and looking for small lines or dots along the frame.

Uneven Caulking

Uneven caulking looks undesirable and unprofessional. It indicates that a contractor lacks training and the right tools for the job. Contact the company that installed your windows and ask them to redo the caulking or call another reliable contractor to do the job correctly this time.

Poor Operability

A window should smoothly open and never vibrate when being opened or cranked. It must not produce any sounds during operation. Furthermore, its pane should not rattle under air pressure. Call your contractor to redo the work if you spot any of these problems.
