There are a lot of home improvement projects that you can easily DIY, but there are a few you shouldnโ€™t attempt to do yourself. Things like electrical work, plumbing, and installing replacement windows should be left to the professionals.

Installing replacement windows is a multi-step process that requires precision every step of the way. Not to mention the tools and equipment that many homeowners donโ€™t have. 

So, can you install windows yourself? Letโ€™s discuss why you should trust this to a professional.

Can I Install Windows Myself?

While you can certainly purchase windows at big box stores and install them yourself, Window World does not sell windows without installing them. When you purchase Window World windows, youโ€™re also purchasing professional installation.

With our installation, you can rest assured that your windows are installed properly the first time. A subpar installation may allow air or water to seep into your home, leaving you vulnerable to bigger issues like mold and mildew growth. This also negates any energy-efficient benefits you were expecting from your windows!

Window installation can also be a time-consuming process for inexperienced homeowners. In contrast, our team can replace an entire house of windows in less than a day. Saving time and money is always a win-win!

Wondering what window installation entails? Letโ€™s dive in.

How to Install Home Windows

The first step in having replacement windows installed in your home is measuring the existing windows. While you can measure your windows yourself, there is a specific way to measure windows for replacement.  Window World windows are custom-made to fit your home, so itโ€™s critical that the measurements are accurate.  Being off by as little as ยผ inch could mean your windows donโ€™t fit perfectly, which opens your home up to the issues we mentioned above.

After your windows are custom-built and ready to be installed, weโ€™ll schedule your installation. On installation day, our technicians will work on the outside of your home to remove your old windows, being careful not to damage your walls. (Weโ€™ll dispose of your old windows for you.)

When installing your new windows, our technicians will ensure they are square and level. Theyโ€™ll also ensure theyโ€™re properly sealed.
