How Installing Energy-Efficient Windows in Swansea Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
  • Save money on electricity bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $316 annually on your energy bills in Swansea.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Swansea

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

How Much Do New Windows Cost?

According to our market research, the typical cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But prices differ 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 provide door installations, which will make your project cost more.

It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Swansea homeowners $316+ a year when replacing single-pane windows.

Requesting free quotes from multiple companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

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

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window replacement company will be able to help you understand what’s best for your needs. In Swansea, the decision will mostly be based on how old your home is and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Swansea

In our hunt to find the most reliable, eco-friendly window installers in Swansea, the EcoWatch team evaluated many companies before settling on these. Along with energy efficiency, we analyzed several window installers in Swansea and ranked them based on the following methodology:

Service Area

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

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received plenty 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 positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want 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 considerable 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

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Swansea, IL Window Replacement FAQs

How much does a window install cost?

The average cost of replacing a single window ranges from $450 to $650. There are a variety of factors that affect the price, including local labor costs, the number of windows, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are and your property’s location.

What type of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

You should use a window installation company whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best left to the professionals.

When is the best time of year to replace windows?

Although you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn’t be raining, since rain can make the installation harder.

How long does it take to install windows?

Because a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.
