How Installing Energy-Efficient Windows in Claremont Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, such as:

• Decrease your carbon footprint: In Claremont, you can cut your indirect greenhouse gas emissions by about 117 pounds per year when you upgrade to energy-efficient windows.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Claremont

Each window replacement company provides various services and has varying price points based on a few factors.

How Much Do New Windows Cost?

According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will add extra costs to your project.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in Claremont.

The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, but 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?

When it comes to window installations, in general there are two types that your installer will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. This means 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.

Your window installation company can advise you on the best type for your project. In Claremont, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Claremont

In our hunt to make your home improvements easier and more eco-friendly in Claremont, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Claremont so you can find the best window installation company near you.

Work Quality

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

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, quality of installation, quality of parts, professionalism and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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