Installing New Windows

Back to List

Installing new windows can give your home the facelift it deserves while improving energy efficiency. Any avid Do-It-Yourself-er can complete a simple window installation project with some preparation, a little teamwork, and careful measuring. If you have any doubts in your ability to install new windows, we'll get you hooked up with one of our licensed and insured Window Pros.

Measuring Up

Getting the right measurements is key when installing new windows. First, determine which brand and model of new window you want to use. Then, measure based on the window manufacturer's instructions. You can usually find this information online. Or, just ask someone at your local home improvement store.

Keep in mind, installing new windows that are slightly smaller than the original windows works better than replacing old windows with larger ones. The existing window opening can be reframed to fit smaller windows.

If installing larger windows than the originals is your thing, you'll have to cut larger window openings. A mistake made when enlarging a window opening is tricky to repair and larger window installation may also require changes to the surrounding support structure of your home. AKA, your house will come tumbling down. So, it's better to leave this kind of upgrade to the Pros.

Reframing

Remember how we said measuring was important? We weren't kidding. It's important to get the measurements right to get the frame looking fresh. Before installing new windows, measure the width of your window at the top, middle, and bottom. Then, measure the height of both sides of the opening as well as the middle. If any of the height and width measurements differ by more than an inch, you may need to reframe the opening.

H2Oh No

Poorly sealed windows give water the chance to seep between the window and the surrounding wall. Water can cause wood to rot or warp and also encourages mold or mildew growth. You may not see the water damage right away. But, if the air in your house begins to remind you of a rainforest, there may be some water problems around your windows.

To have maximum protection against water damage, seal windows with a combination of self-adhering waterproof membrane, metal flashing, and caulk, and you're good to go!

It Takes (At Least) Two

Installing new windows is not a one-person job. At the very least, you need one person to hold the window while the second person levels it and nails it into place. Large windows may require more than two people to hold the window steady. So, get your crew together beforehand.

Second-story window installation requires a ladder or scaffolding, which can increase the risk of falls and injury. Unless you have experience working at heights, leave second-story window installation to our Home Pros.
