How Installing Energy-Efficient Windows in Swansea Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could benefit you:

• Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
• Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Swansea

Each window replacement company offers various services and has varying prices based on a few factors.

How Much Do New Windows Cost?

The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

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 offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using 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 offer decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot or deterioration. Because these installations are more involved, they will raise the total cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you’re unsure which window installation service you should get, your installer can advise you. Generally, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Swansea

The EcoWatch Reviews team is different from most reviewers since we examine these companies through a sustainability lens. We have evaluated the best window installers in Swansea primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Swansea, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Swansea.

Work Quality

When choosing new windows, the quality and breadth 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 consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, warranty, professionalism, cost, quality of parts 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 points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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