How Installing Energy-Efficient Windows in Fairhaven Saves You Money

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

• Reduce your carbon footprint: By using less energy after 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 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 harmful UV rays.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.

Estimated Cost of Window Replacement in Fairhaven

Each window installation company provides varying services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

Typically, homeowners in Fairhaven can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. How much it will cost is based on several factors, including number of windows, size, the location of your home, material, type and more.

Whether or not you want to install 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 $460 a year on your energy bills in Fairhaven.

The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step of a replacement is to think about whether you should get a full-frame or pocket installation.

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

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

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Fairhaven 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 company in our guide to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Fairhaven’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Fairhaven window companies to prepare homes for the climate.
