How Installing Energy-Efficient Windows in Nottingham Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Nottingham

Each window replacement company provides various services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

Though the national average to replace a single window is around $600, it can range from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

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

The cost of your window installation 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 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company will be able to advise you on the best type for your project. In Nottingham, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Nottingham

EcoWatch differs from most reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Nottingham and ranked them using the following methodology:

Service Area

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

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand 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

Customer feedback is another super important review factor. If most customers don't have nice feedback about their experience with a certain company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Nottingham, NH Window Replacement FAQs

What is the average cost to replace windows in a home?

The typical cost of installing one window ranges between $450 and $650. There are many factors that influence how much it costs, including how energy-efficient the windows are, styles and sizes of windows, local labor costs, the number of windows, the materials used in designing the windows and your property's location.

What type of window is the best for energy efficiency?

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

Can you replace your own windows?

If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or experience, we don't recommend doing it on your own.

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

Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.

How do you know it's time to replace your windows?

Windows generally have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them checked by an expert to see if they need any repairs or replacements.
