Installing your own windows might cost less, but this is only true if you’re able to install them properly. Improper window installation could lead to costly mistakes, including the worst-case scenario of having to replace a faulty install. Hiring a professional contractor to install your new windows often proves more cost effective in the long run as it avoids mistakes and helps the window perform as designed. We can help you find a contractor in your area who specializes in our products.  

There could be some financial advantages to a full-home window replacement rather than a phased approach. Here’s what could make it less expensive to replace all your windows at once:

When you meet with your contractor, ask them how they minimize heat loss during cold weather installations. Find out all the questions to ask your contractor.

• Insulating curtains and window films — the type used for privacy, insulation, and decoration — can interfere with your window’s low-emissivity coating and lead to seal failure.
• Leaving a clad-wood window, which has a wood interior, unfinished can lead to damage that ultimately shortens a window’s lifespan.
• Unchecked interior condensation can lead to mold and rot that damages and eventually deteriorates the window. Interior condensation results from too high humidity in the home. Learn more about window condensation.
