Signs of Bad Window Installation to Watch Out For

Today’s replacement windows are manufactured to improve the aesthetics and energy efficiency of your home. However, you won’t be able to fully enjoy these benefits if the windows aren’t installed properly. Faulty windows can lead to ongoing problems that compromise your home’s weather protection, energy efficiency and comfort levels.

As your local source of replacement windows and patio doors, we recommend keeping an eye out for these signs of bad window installation:


You shouldn’t experience drafts if you have newer windows. Drafts force your HVAC system to work harder, leading to soaring energy bills. If you notice drafts and an uptick in energy bills, faulty window installation could be the culprit.

Difficulty in Operation

Windows and entry doors should be easy to open and close. If they aren’t, it could mean the units weren’t measured accurately prior to installation. Reach out to the pros right away while the affected windows are still covered by warranty.

Window Condensation

If you notice your windows are getting foggy, it could mean that the seals have failed early or the units weren’t installed correctly. If the condensation appears in between the glass panes, this is a sign of seal failure. If this happens, the gas fill between the window panes has escaped, making the windows less energy-efficient and unable to provide proper insulation for your home.
