How Installing Energy-Efficient Windows in Sandown Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save more on your bills.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Sandown, that's about 152 pounds per year on average.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Sandown

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

How Much Do New Windows Cost?

Typically, Sandown homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. These numbers are based on specific characteristics of your installation, including the location of your home, material, type, size, number of windows and more.

It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Sandown homeowners $435+ a year when replacing single-pane windows.

Something else that influences the overall cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

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

How We Choose the Best Window Installers in Sandown

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

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Sandown 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 on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including warranty, professionalism, quality of parts, quality of installation, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave 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 be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Sandown, NH Window Replacement FAQs

How much should a window install cost?

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

What are the different kinds of windows?

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

Do you really have to use a window installation company?

You should use a window installation company whenever you want new windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.

When is the best time of year to replace windows?

Although you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, as rain can make the installation harder.

Should I replace my windows all at once?

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