Can I replace my own windows?

You might be thinking about tackling window replacement as a DIY project. While you absolutely can replace your own windows, Infinity from Marvin fiberglass windows are not available for DIY installation. Learn more about why hiring a local professional will make your window replacement project easier.

In-home or virtual
replacement consultation

Talking about replacement windows and doors might not sound like a lot of fun, but we’re changing that. During your appointment, your Infinity expert will take the time to do a needs assessment. They will work with you to explore our style options to design the perfect windows or doors for you and answer any questions you may have.

Measuring your window and door openings

Your window and door openings will be measured twice to make sure the right size is ordered. During your consultation, your windows and doors will first be measured to generate your quote. Once your project proposal has been signed, a measure technician will return to double-check all measurements before your order is placed.

Professional ordering

Rather than ordering windows and doors on your own at a lumberyard or at a big box store and relying on them to submit everything correctly, your Infinity windows will be ordered directly from our factory. Our production team custom builds all Infinity windows and doors to your project’s exact window and door opening measurements. Your Infinity expert will handle all the details so your order arrives exactly how you specified. If something doesn’t turn out how you wanted, they work with us to make it right. Since they’re managing every detail of your installation, you won’t have to worry about ordering the wrong window or door.


Handling local codes

From pulling permits to helping you identify permits that need to be pulled, Infinity's local independent partners can help navigate local codes and regulations.


Prepping your home for installation

Each job has slightly different installation requirements, but you’ll get complete prep instructions so you can get ready. Typically, you’ll need to put away any fragile items, disable your alarm system and pull furniture away from windows. Infinity experts have just about seen it all, so they’ll help you learn how to get your home ready.


Window and door installation

Even with a few home improvement projects under your belt, window and door replacement is an art. From shimming to trim work, using a professional window and door replacement company like an Infinity local independent partner gives you peace of mind. Plus, they take care of the clean-up.



A reputable window replacement company should stand behind their work with a labor warranty. With DIY installation, you have to stand behind your work. Infinity provides a Limited Lifetime Warranty on its windows and doors. We’re proud to stand behind our product.
