Why It’s Best to Let the Pros Install Your New Windows

DIY window installations might seem more cost-effective than professional window installations at first. However, they almost always end up costing homeowners more in the long run. As a rule of thumb, it’s best to let experienced professionals handle the installation of your windows and doors.

Why It’s Best to Let the Pros Install Your New Windows

Here’s why it makes more practical and financial sense to hire a professional contractor to install your windows and doors:


First-time DIYers often make the basic—but costly—mistake of underestimating how much time they need to finish installing windows. In general, it takes professional window contractors roughly 40 to 60 minutes to install a new window. First-time DIYers, however, will need more time to finish their project.

Compounding the problem of time mismanagement is the fact most homeowners can only do home improvement projects on weekends. If they end up postponing the completion of the project to next weekend, their home will be left exposed to the elements, which unnecessarily increases the risk of damage to the interior.

Little Room for Error

Aside from time mismanagement, DIY window installations usually take longer to finish because of basic installation errors, which first-time DIYers are prone to making. Remember: there’s little room for error in home improvement projects. For instance, even a tiny gap between your wall and the window frame can allow moisture to infiltrate your home or heat or conditioned air to escape.

Use of Specialist Tools

A key reason why first-time DIYers almost always make installation mistakes is that they don’t have the necessary skills and training to handle the tools used to install windows and specialized doors such as French doors.  It normally takes years to learn how to use these tools properly.

One more thing: if you decide to have a don’t forget to vet a professional contractor. That way, you can rest easy knowing that your new windows will be installed correctly.
