How Installing Energy-Efficient Windows in Bolton Saves You Money

There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Bolton, that's about 147 pounds per year on average.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Bolton

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

How Much Do New Windows Cost?

On average, Bolton homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will add extra costs to your project.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Bolton homeowners $461+ each year after replacing single-pane windows.

We recommend requesting free quotes from multiple window companies to find the one that works best for you.

What Services do Window Installers Offer?

The first step when considering a window replacement is to think about whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant rot. Because full-frame installations are more involved, they will raise the overall cost. A pocket installation entails replacing a window within the frame that's already there. So, instead of removing the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

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

How We Choose the Best Window Installers in Bolton

The EcoWatch Reviews team is different from most reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Bolton area so you can find the right window installation company near you.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included in our guide to make sure its contractors 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 customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, quality of installation, professionalism, cost, quality of parts and more.

Cost

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

Warranty

As discussed, windows are a significant investment, so you'll want to make sure that investment is protected. 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 a while. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Bolton, CT Window Replacement FAQs

What is the average cost to install new windows?

The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the types of windows?

The most common types of windows for homes are transom windows, bay windows, double-hung and single-hung windows, awning windows, picture windows, slider windows and casement windows.

What do window installers do?

Window installation companies cover the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.

What time of year is a good time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.

How often should you replace windows?

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