How Installing Energy-Efficient Windows in Leicester Saves You Money

There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• 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 due to their ability to filter out damaging UV rays.
• 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. Upgrading to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: In Leicester, you can lower your indirect greenhouse gas emissions by about 139 pounds per year when you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Leicester

When considering window installation, each company provides varying services and costs. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Leicester can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. These figures are based on the specifics of your installation, like the location of your home, type, material, size, number of windows and more.

Whether or not you pick 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 $482 a year on your energy bills in Leicester.

Something else that affects the total cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the full window, including the trim, frame and sill. A pocket installation entails replacing a window without taking out the entire frame, which tends to be cheaper than a full-frame installation.

If you’re still debating which kind of installation you need, you can ask your provider and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Leicester

The EcoWatch Reviews team is different from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Leicester, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Leicester.

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 installer included in our guide to ensure its technicians are well-qualified and that the company has gotten 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 good things to say about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily 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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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