Replacement Window Contractor Milwaukee

The quality of your window installer is just as important as the quality of your replacement windows. With the wrong contractor, you can end up with a poor window installation that lets in too much air or even damages the window. With the right window installer, your quality replacement windows can keep your home tightly sealed and last for decades. But how do you find the right contractor? Here’s a handy checklist to refer to so you can ensure that you hire the best.


Any window contractor that’s been in business for any amount of time, will have built a reputation — but it matters what kind. The first place to look is Better Business Bureau. They rate businesses of all kinds based on 13 different criteria, so you know when you see an A+ rating on BBB, that it’s been carefully considered. They also offer information such as, how long the business has been in operation and customer reviews. Taking a look at associations that the contractor is involved with and any awards they’ve won, also helps to get a sense of reputation.

Testimonials & Reviews

While you’re on BBB, you’ll want to take a look at those customer reviews. However, if there are none available on BBB, you can check Google or industry specific sites such as Angie’s List or Houzz. You may even be able to find reviews on social media. You should also ask the contractor for testimonials from satisfied customers to get further details. Take in several different reviews, not just one or two, to get a full picture of the kind of service you can expect.

License and Insurance

It’s good to make sure that the window installer is reputable and that their customers have been pleased with the experience they’ve had, but you’ll also want to ensure that they’re legitimate. Ask for proof of their license that allows them to legally work on your home. You should also ask about their insurance, since their level of insurance will protect you from being held liable in the event that any accidents happen on the job.


What kind of warranties do they offer? Many contractors will say that they offer a lifetime warranty, but you’ll want to make sure you know what that means, before you hire them. If the lifetime warranty doesn’t include both product and labor, it’s not a real lifetime warranty. Look for something that offers a lifetime warranty for both the product, the installation, and even covers things like glass breakage. This way you can rest easy with your choice.


We all know that home improvement projects — even replacement windows — can be expensive. What if you need your windows replaced pronto, but you don’t have the budget for it? If that’s the case, you’ll want to ask the contractor about their financing plans. With financing, you can find a payment plan that helps to make your replacement window installation more manageable.


At some point when considering a window installer, you’ll probably ask for an estimate. Consider this part of the process carefully. How thoroughly does the estimate answer all your questions. Does the contractor try to pressure you to make a decision or threaten to raise the cost if you don’t decide right away? What are the projected targets to finish the project? It’s a good idea to get a few estimates so that you can compare and determine whether or not the estimate you have is a good one.
