How Installing Energy-Efficient Windows in Bryn Mawr-Skyway Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Bryn Mawr-Skyway, that’s about 271 pounds per year on average.
- Save on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $366 annually on your energy bills in Bryn Mawr-Skyway.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Protect your investment: If your home is on the older side, your windows are most likely outdated.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 increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Bryn Mawr-Skyway
Windows come in various styles, purposes and shapes, so costs and services will differ considerably based on your project. Below, we go over the typical cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Generally, Bryn Mawr-Skyway homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost varies based on several factors, such as size, type, the location of your home, number of windows, material and more.
Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $366 a year on your energy bills in Bryn Mawr-Skyway.
Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re unsure which kind of window installation service you should get, your installer can advise you. In general, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Bryn Mawr-Skyway
EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We have evaluated the best window installers in Bryn Mawr-Skyway mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. 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 self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
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 included on this list to make sure its technicians are well-qualified and that the company has received 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 nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Bryn Mawr-Skyway, WA Window Replacement FAQs
What is the typical cost to install new windows?
The typical cost to install a window ranges between $450 and $650. There are several factors that influence how much it costs, which include how energy-efficient the windows are, the materials used in designing the windows, your property’s location, local labor costs, the number of windows and styles and sizes of windows.
What are the different types of windows?
The most common types of windows for homes are double-hung and single-hung windows, slider windows, picture windows, awning windows, bay windows, transom windows and casement windows.
Can you replace your own windows?
If you’re handy and have experience with installing a replacement window, it’s possible to install your own windows. But if you don’t have the time or know-how, we recommend hiring a professional.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
