How Installing Energy-Efficient Windows in Westborough Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

• Decrease your carbon footprint: In Westborough, you can reduce your indirect greenhouse gas emissions by about 139 pounds per year once you install energy-efficient windows.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Save money on energy bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Westborough

Let’s go over the cost of updating your windows and the types of services offered by installers.

How Much Do New Windows Cost?

According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. Costs will differ significantly depending on your location, the number of windows you need, the quality of your products and the current condition of your home. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Westborough homeowners $482+ each year after replacing single-pane windows.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations entail replacing the complete window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. Because these installations are more involved, they will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re unsure which kind of window installation service you should get, your installer should be able to advise you. Generally, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

Service Area

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

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for.

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

Cost

This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

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