Estimated Cost of Window Replacement in Shrewsbury

Windows come in different styles, shapes and purposes, so costs and services will differ remarkably depending on your project. Below, we describe the average cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range from $200 to $1,200. How much it will cost depends on several factors, such as size, material, the location of your home, number of windows, type and more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Shrewsbury homeowners $482+ per year after replacing single-pane windows.

What Services do Window Installers Offer?

The first step of a replacement is to decide whether you need a full-frame or pocket installation.

A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

Your window installation company will be able to help you figure out what’s best for your needs. In Shrewsbury, the decision will mostly depend on the age of your windows and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Shrewsbury

In our search to make your home improvements easier and more eco-friendly in Shrewsbury, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Shrewsbury, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Shrewsbury.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive things to say about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to make sure 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

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
