How Installing Energy-Efficient Windows in Dartmouth Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could help you:

• Save on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
• Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Dartmouth

Each window replacement company offers various services and has varying price points depending on several factors.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These amounts vary based on the specifics of your installation, like number of windows, type, material, the location of your home, size and more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Something else that affects the total cost is the material of the frame you choose. Aluminum frames are usually the least pricey 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 step of a window replacement is to think about whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has noticeable damage or rot. Full-frame installations are more involved and will increase overall costs. A pocket installation entails replacing a window without replacing the frame. So, instead of tearing out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Dartmouth, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Dartmouth

The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Dartmouth and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Dartmouth, we paid more attention 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 Dartmouth.

Work Quality

When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, warranty, quality of installation, cost, professionalism and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want 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 previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
