How Installing Energy-Efficient Windows in Dorr Saves You Money

There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on energy bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.

Estimated Cost of Window Replacement in Dorr

Let’s take a look at the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

On average, Dorr homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at about $600. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Dorr home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

In general, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has significant damage. These installations are more involved and will raise the total cost. A pocket installation entails replacing a window within the existing frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can advise you on the best type for your project. In Dorr, the choice will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Dorr

EcoWatch is different from most reviewers because we assess these companies through a sustainability lens. We’ve assessed the top window installers in Dorr mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Dorr area so you can find a quality 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 featured on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their experience with a certain company, it won’t be 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 gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Dorr’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Dorr window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
