How Installing Energy-Efficient Windows in Chelmsford Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to think about making the switch:

• Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
• Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 139 pounds.

Estimated Cost of Window Replacement in Chelmsford

Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

According to our research, the average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, including size, material, the location of your home, number of windows, type and more.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Something else that affects the total cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer 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 as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot. With this service, your professionals will replace the whole window, including the sill, trim and frame. 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.

If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their recommendation. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Chelmsford

In our search to make your home improvements easier and more eco-friendly in Chelmsford, the EcoWatch team chose the above companies as the best window installation companies in the city. We've decided to review the best window installation companies in Chelmsford mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Chelmsford, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Chelmsford.

Work Quality

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

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, quality of parts, professionalism, warranty, quality of installation and more.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, 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 been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
