How Installing Energy-Efficient Windows in Gilford Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, such as:

  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
  • Save on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your home.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Gilford, that's about 152 pounds per year on average.

Estimated Cost of Window Replacement in Gilford

Each window installation company offers varying services and has different price points based on several factors.

How Much Do New Windows Cost?

Even though the typical of replacing one window is about $600, it can range anywhere from $200 to $1,200. Costs will vary considerably based on the current condition of your home, the quality of your products, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.

It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Gilford home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Getting free quotes from multiple providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Gilford

In our search to find the most reliable, eco-friendly window installers in Gilford, EcoWatch assessed many companies before landing on these. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Gilford, we paid more attention to companies that serve 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 Gilford.

Work Quality

When it comes to new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, professionalism, cost, warranty and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try 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. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. 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.

Gilford, NH Window Replacement FAQs

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

The national average cost to replace a window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What are the kinds of windows?

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

Can you install your own windows?

If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure 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 most important is that the weather should be dry.

Should I replace all my windows at once?

If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
