Signs Your Home’s Windows Were Installed Incorrectly

Home window replacement is hardly a DIY project and should be entrusted to a reputable and experienced contractor in order to keep the manufacturer’s warranty intact.  Failure to thoroughly vet a pro can leave you with a result that costs you big in terms of time, money, and frustration.  If you notice any of these scenarios after your new house windows have been installed, it’s likely your contractor cut corners or didn’t have the necessary level of expertise to complete the project.

Careless Caulking: The purpose of caulking around house windows is to provide a completed look, while also warding off air or water infiltration.  If you find the caulking to be sloppy or have an incomplete look, it’s likely the window installer’s work will not stand the test of time.  This can also contribute to elevated heating costs.


Air Infiltration: If you’re feeling drafts that weren’t present before your windows were installed, it’s likely that they are to blame.  Common installation mistakes can include too large of a space between the window and the frame.  An inadequate amount of foam insulation between the rough opening and the window can also cause window drafts.  Windows absent of the correct levels of insulation around their perimeter all but guarantee that an issue with air infiltration is just a matter of time.  Frustratingly enough, air infiltration can often lead to a sharp jump in energy bills.

Difficulties Operating Your Windows: If your windows are hard to open and close from day one, it’s likely that they were not properly installed.

Water Infiltration: Windows installed by a rookie contactor are frequently subject to water infiltration.  This permits mold to grow on the window frame and causes paint to peel. It isn’t long before a home’s carpeting and walls are subject to pricy fixes.

Go Behind the Scenes on Twin Cities Infinity from Marvin® Window Installation Project: 

Visible Gaps: Gaps between the windowsill and frame indicate that the windows were incorrectly measured.  In this case, it’s likely that the frame of the window is too large for the glass.

Foggy Panes: When this installation error happens, it frequently means that the window gas inside the window has been compromised due to the carelessness of the installer.

Our Twin Cities Window Replacement Reviews:

I had all my windows, screens and trim replaced in a 3rd floor corner condo. The new windows are fantastic. In cold weather my unit is now about 7 degrees warmer with no drafts. The installation occurred in below zero temperatures and the crew did a tremendous job. A follow-up visit by their quality assurance inspector insured that everything was done to their high standards. I would recommend this company without reservation.

"Lindus Construction was selected to replace six windows in my home. The crew arrived on schedule and performed the installation in two days. The workers did a great job and were very careful in cleanup and avoiding the tracking of snow into my living space. The work was carried out in a very professional manner. I would not hesitate to recommend the company to others."
