Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. The Department of Energy estimates that heat gained or lost through old or damaged windows could make up close to 30% of residential energy climate costs. In Sandown, where the electric bills are an average of $35 per month, that's almost $$124 per year wasted.
That's bad news for both your bank account and the environment, but one of the top window installation companies can help you with that.
As windows are so important for your home, choosing the best company for you is a big decision to make. That's why the EcoWatch team has put together this list of the best window replacement companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Sandown Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Save money on energy 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 decrease that amount, which helps you save more on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Better temperature control in your home: Living in a cold place like Sandown often means relying on your heater to keep your home cool. Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
Estimated Cost of Window Replacement in Sandown
When considering window installation, each company offers varying services and prices. Let's look at some average costs and services.
How Much Do New Windows Cost?
On average, homeowners in Sandown can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. These figures are based on the specifics of your installation, such as size, number of windows, material, type, the location of your home and more.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $435 a year on your energy bills in Sandown.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies offer: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the entire window, including the sill, frame and trim. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which type of installation you should get, you can talk to your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Sandown
EcoWatch reviews are different from most reviews because we assess these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Sandown and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Sandown area so you can find the right window installation company near you.
Work Quality
We're certain 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 technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Sandown, NH Window Replacement FAQs
How much should window installation cost?
The typical cost of installing one window ranges from $450 to $650. There are many factors that influence the cost, including the number of windows, styles and sizes of windows, your property's location, the materials used in designing the windows, local labor costs and how energy-efficient the windows are.
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.
What do window installation companies do?
Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation harder.
