Time to replace your windows?

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: 

• You could be eligible for a volume discount if you’re purchasing a larger quantity of windows at one time. Promotional discounts are determined by the retailer or dealer where you purchase from Andersen doesn’t sell directly to homeowners. 
• If you’re financing your window project. You’ll likely pay less interest if you replace the full home at once, instead of financing several different window replacement projects. Financing is commonly available either through Andersen Certified Contractors or The Home Depot.

• 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.
