Why you can trust EcoWatch
Whether you're doing home renovations or have windows that need repairs, windows play a important role in conserving energy in your home. If your house has traditional, outdated windows, your HVAC system could be working overtime to heat or cool your home. This means spending more on electricity bills.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during the summer and winter, but also saving you some money and helping the environment.
Unlike other review sites, EcoWatch ranks window replacement companies on energy efficiency while also considering cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Swansea Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Save money on power bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $316 annually on your energy bills in Swansea.
Estimated Cost of Window Replacement in Swansea
Let's go over the cost of window replacement and the types of services offered by installers.
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 per window. But prices vary 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 offer door replacements, which will make your project cost more.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Swansea homeowners $316+ a year when replacing single-pane windows.
Requesting free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
In regard to window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot. Full-frame installations are more involved and will raise the overall cost. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Swansea
EcoWatch reviews are different from most reviews since we assess these companies through a sustainability lens. We have assessed the top window installers in Swansea mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Swansea so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as 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 previously, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Swansea's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Swansea window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Swansea, IL Window Replacement FAQs
How much does window installation cost?
The typical cost of replacing one window ranges between $450 and $650. There are several factors that influence how much it costs, such as how energy-efficient the windows are, the materials used in designing the windows, the number of windows, styles and sizes of windows, local labor costs and your property's location.
What kind of window is the most energy-efficient?
A window's energy efficiency is influenced by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can I install my own windows?
While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How often do you need to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
