Is It a Good Idea to Replace Windows by Yourself?

You probably think you can save money by completing home improvement projects on your own rather than hiring a contractor. Unfortunately, without proper knowledge and training, you’re at risk of damaging your property, which will cost more to repair than you would have spent if you’d hired an experienced professional in the first place.

In today’s post, your leading door replacement expert, Renewal by Andersen® of Seattle, discusses whether or not you should attempt to replace windows on your own.

New Construction and Replacement Windows

You can’t just buy any old window and install it in your home. New-construction windows aren’t meant for existing homes. They are used for new-construction homes or new additions. These windows have nailing fins on the front so they can be nailed flat to the front of the house.

Replacement windows are specifically designed to be installed in existing wall openings when the old, original windows have reached the end of their lifespan. The same is true of replacement gliding patio doors. They don’t have nailing fins, allowing them to fit into the window opening.

DIY Replacement Windows

You can buy DIY replacement windows in stores, but it’s unlikely they’ll be a perfect fit for your home as they come in pre-cut sizes. This can lead to a host of problems, including reduced energy efficiency.

Plus, installing the windows on your own is not as easy as you might think. Window installers have the proper tools and have undergone extensive training on how to complete the job safely and accurately. They can do the work faster and more efficiently.

Installers often attach an aluminum exterior cladding that matches the color of the windows. They also securely seal the windows for protection against the weather. Keep in mind that custom tools are required to form the cladding, and it can be a challenge to work with aluminum especially if you don’t have experience.

Avoid wasting time, effort and money. Window and door replacement projects are best left to professionals, who can do the job correctly and more safely than a DIY enthusiast.
