Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s efficiency can also have a big impact on home energy conservation. If you have traditional, outdated windows, your HVAC system could be working extra hard to heat or cool your home. This means spending more on energy bills.
Replacement windows improve your home’s insulation, not only making you more comfortable during the summer and winter, but also saving you money and helping the environment.
As windows are so important for your home, choosing the best company for you is a big choice to make. That’s why the EcoWatch team has made this list of the top window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Redland Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
- Decrease your carbon footprint: In Redland, you can lower your indirect greenhouse gas emissions by about 234 pounds per year once you install energy-efficient windows.
- Save on energy bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $294 annually on your energy bills in Redland.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Redland
Windows come in various shapes, purposes and styles, so costs and services will differ greatly based on your project. Below, we describe the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, such as material, size, number of windows, the location of your home, type and more.
It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Redland homeowners $294+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re unsure which kind of window installation service you need, your installer can advise you. In general, the choice depends on 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 Redland
EcoWatch reviews differ from other reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
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
When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of installation, cost, quality of parts, professionalism and more.
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 providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with 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 been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Redland, MD Window Replacement FAQs
How much should a window install cost?
The typical cost to replace a window can range between $450 and $650. There are a variety of factors that affect how much it costs, which include your property’s location, the number of windows, how energy-efficient the windows are, local labor costs, styles and sizes of windows and the materials used in designing the windows.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installers cover the entire process — from replacing old windows with brand-new ones to cleaning up afterward. In addition, many companies offer window manufacturing, customization and repairs.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it’s probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
