How Installing Energy-Efficient Windows in London Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- More efficient energy use in your home: In London where the winters can get very cold, energy-efficient windows decrease how much heat is lost through your windows, which makes it easier to keep your house warm.
- Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- 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.
Estimated Cost of Window Replacement in London
Windows come in varying styles, shapes and purposes, so costs and services will differ greatly depending on your project. Below, we go over the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These numbers vary depending on the specifics of your installation, such as material, size, the location of your home, type, number of windows and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
If you're still trying to decide which kind of installation to get, you can consult with your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in London
EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. We have assessed the top window replacement companies in London mostly 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 is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, warranty, cost, professionalism, quality of installation and more.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
London, OH Window Replacement FAQs
What is the typical cost to install new windows?
The typical cost to install a window can range between $450 and $650. There are many factors that influence the cost, 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 are the kinds of windows?
The most common types of windows for homes include: double-hung and single-hung windows, bay windows, casement windows, picture windows, transom windows, awning windows and slider windows.
When do I need to use a window installation company?
Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
How often should you replace windows?
Windows generally last 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them checked by an expert to determine if they are in need of a repair or replacement.
