How Installing Energy-Efficient Windows in Danville Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:

  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
  • Reduce your carbon footprint: In Danville, you can reduce your indirect greenhouse gas emissions by about 152 pounds per year once you switch to energy-efficient windows.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Danville

Windows come in varying shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Though the average to install a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost you is based on several factors, including size, the location of your home, type, material, number of windows and more.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Danville homeowners $435+ a year after replacing single-pane windows.

Asking for free quotes from multiple companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

Generally, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the complete window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage. Because full-frame installations are more involved, they will raise overall costs. A pocket installation entails installing a new window within the frame that's already there. 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 installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Danville

EcoWatch reviews differ from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:

Service Area

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

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain installer, you won't see it featured on EcoWatch.

Cost

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

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies with 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Danville, NH Window Replacement FAQs

How much does window installation cost?

The average cost to install a window ranges from $450 to $650. There are many factors that affect how much it costs, including your property's location, styles and sizes of windows, local labor costs, the materials used in designing the windows, the number of windows and how energy-efficient the windows are.

What are the kinds of windows?

There are several different types of windows you can get for your house, such as transom windows, double-hung and single-hung windows, casement windows, bay windows, picture windows, awning windows and slider windows.

When do I have to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.

How long does window installation generally take?

Because a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.

Should I replace my windows all at the same time?

If you're upgrading your windows to save on your energy bills, replacing all your windows together is the only way to gain that benefit. However, if you have just a few windows that are broken or drafty, you can replace just those.
