How Installing Energy-Efficient Windows in Marlborough Saves You Money

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

  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Marlborough, that's about 147 pounds per year on average.

Estimated Cost of Window Replacement in Marlborough

Let's go over the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Marlborough homeowners $446+ per year after replacing single-pane windows.

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. So, instead of removing the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you figure out what's best for your needs. In Marlborough, the decision will mostly be based on how old your windows are and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Marlborough

In our search to find the most reliable, eco-friendly window installers in Marlborough, EcoWatch assessed dozens of companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Marlborough and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do rate window installers higher 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 find the companies with the most consistent 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 quality of installation, quality of parts, cost, warranty, professionalism and more.

Cost

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

Warranty

Protecting your investment in new windows is important. That's why window installation companies that provide 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 a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Marlborough, CT Window Replacement FAQs

What is the typical cost to install windows?

The average cost to replace one window can range between $450 and $650. There are many factors that influence the cost, which include how energy-efficient the windows are, styles and sizes of windows, local labor costs, the materials used in designing the windows, your property's location and the number of windows.

Which kind of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

Do I really need to use a window installation company?

You should use a window installation professional whenever you need new windows. Installing windows is a involved process that can be difficult to do on your own, so it's best left to the professionals.

How often do you need to replace your windows?

Windows typically last around 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them checked by an expert to determine if they are in need of a repair or replacement.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
