Is Replacement Window Installation a DIY Project?

Is Replacement Window Installation a DIY Project?

Looking For a Local Contractor Fast?

August 9, 2010

Replacing your windows can improve your home's appearance and lower your heating and cooling bills, but is it a project you should tackle yourself? The answer is a resounding maybe. There are a few things you should consider before you decide to forgo hiring a window contractor and do a replacement window installation on your own.

Are You an Experienced DIYer?

Safety is a very important consideration with any home improvement project. A replacement window installation often requires a helper, especially when working with double windows or on a second floor. A window installation can also involve:

  • Working on a ladder
  • Removing and installing easily breakable glass
  • Carrying heavy materials
  • Using sharp tools

If you are an experienced DIYer, you might consider installing your own replacement windows to be just another day at the office, but if you are a novice DIYer, it might be safer watching a window contractor install your windows and using the project as a learning experience.

What Does Your Replacement Window Installation Involve?

Some replacement window installations are a little more DIY friendly than others. Many homeowners change window styles, types, or sizes during a replacement window project, and these changes can involve framing, drywall, and exterior siding modifications. Other homeowners choose replacement windows that fit their existing window openings, and the replacement window installation simply involves removing the existing window and sliding the new window into place.

An uncomplicated replacement window project may be suitable for a novice DIYer, but a replacement that requires framing changes might best be handled by a window contractor, especially if a building permit is needed.

Window Warranties

Many window contractors work with specific replacement window manufacturers and are trained in proper installation techniques. If you have problems with a replacement window after it has been installed, you may have better success at having the warranty honored if the window was installed by a professional.
