How Installing Energy-Efficient Windows in Bristol Saves You Money

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

• Save on energy bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
• Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Bristol

When looking into window installation, each company provides different services and costs. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost depends on several factors, including type, the location of your home, number of windows, size, material and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows 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, purchasing certified energy-efficient windows can save Bristol homeowners $312+ each year after replacing single-pane windows.

What Services do Window Installers Offer?

The first step of a replacement is to figure out whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has considerable rot or deterioration. Because these installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

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

How We Choose the Best Window Installers in Bristol

EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Bristol and ranked them based on the following methodology:

Service Area

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

Work Quality

We’re willing to bet 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 plenty 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 customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of parts, quality of installation, cost, professionalism and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. 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

Because of Bristol’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Bristol window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
