How Installing Energy-Efficient Windows in Epsom Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $477 a year on your bills.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Epsom

Windows come in different purposes, shapes and styles, so costs and services will vary greatly based on your project. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Generally, Epsom homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at around $600. But costs will vary significantly depending on the number of windows you need, the quality of your products, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $477 a year on your energy bills in Epsom.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has considerable damage or rot. Because full-frame installations are more involved, they will increase the overall cost. Pocket installations are simpler and won't cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

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

How We Choose the Best Window Installers in Epsom

EcoWatch reviews are different from most reviews, as we look at these companies through a sustainability lens. We've decided to evaluate the best window replacement companies in Epsom primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Epsom, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Epsom.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of installation, warranty, quality of parts and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies with 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 years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
