Estimated Cost of Window Replacement in Niles

How Much Do New Windows Cost?

Generally, Niles homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. But costs will vary significantly based on your location, the current condition of your home, the number of windows you need and the quality of your products.

Asking for free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first step when planning a replacement is to think about whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Niles

In our search to make your home improvements easier and more eco-friendly in Niles, the EcoWatch team evaluated many companies before deciding on these. We’ve decided to assess the top window replacement companies in Niles mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
