Estimated Cost of Window Replacement in Dennis

Each window installation company offers varying services and has different costs based on several factors.

How Much Do New Windows Cost?

Typically, Dennis homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at about $600. How much it will cost depends on several factors, such as size, type, number of windows, material, the location of your home and more.

It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Dennis home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that influences the total cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Dennis

The EcoWatch Reviews team is different from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Dennis and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Dennis area so you can find the right window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, warranty, quality of installation, cost, quality of parts and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
