How Installing Energy-Efficient Windows in Exeter Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:

• Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Exeter

Each window installer provides varying services and has different prices depending on several factors.

How Much Do New Windows Cost?

On average, Exeter homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. These estimates are based on the specifics of your installation, such as size, material, type, number of windows, the location of your home and more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage. Because these installations are more involved, they will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

If you’re not sure which type of window installation service you need, your installer should be able to assist you. Generally, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

The EcoWatch Reviews team differs from other reviewers since we assess these companies through a sustainability lens. We’ve decided to review the top window installers in Exeter mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Exeter, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Exeter.

Work Quality

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

Customer Reviews

We analyzed patterns in recent online reviews 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 nearly every category, including warranty, quality of parts, professionalism, cost, quality of installation and more.

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 awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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