How Installing Energy-Efficient Windows in Derby Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:

• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
• Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• 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.
• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Derby

Let’s take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. But costs differ remarkably 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 provide door replacements, which will add extra costs to your project.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Derby homeowners $511+ per year after replacing single-pane windows.

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

What Services do Window Installers Offer?

The first step when planning a window installation is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re unsure which type of window installation service you should get, your installer should be able to help you out. Generally, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Derby

In our hunt to make your home improvements easier and more eco-friendly in Derby, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Derby, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Derby.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of parts, quality of installation, warranty, cost and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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