How Installing Energy-Efficient Windows in West Concord Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could help you:
- Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: In West Concord, you can reduce your indirect greenhouse gas emissions by about 139 pounds per year after you upgrade to energy-efficient windows.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in West Concord
Each window replacement company provides various services and has different prices based on several factors.
How Much Do New Windows Cost?
On average, homeowners in West Concord can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. These numbers vary based on the specifics of your installation, such as size, type, number of windows, the location of your home, material and more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save West Concord homeowners $464+ a year after replacing single-pane windows.
How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are completely 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?
In regard to window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you're still debating which kind of installation to get, you can ask your provider and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in West Concord
EcoWatch is different from most reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in West Concord and assigned rankings using the following methodology:
Service Area
Since this is a guide for West Concord, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in West Concord.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, cost, warranty, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to West Concord's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of West Concord window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
West Concord, MA Window Replacement FAQs
How much does a window install cost?
The typical cost of replacing a window can range between $450 and $650. There are several factors that influence the price, such as how energy-efficient the windows are, the number of windows, local labor costs, styles and sizes of windows, the materials used in designing the windows and your property's location.
What are the most common kinds of replacement windows?
There are various types of windows you can get for your house, such as transom windows, casement windows, double-hung and single-hung windows, bay windows, slider windows, awning windows and picture windows.
Do you really need to use a window installation company?
Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is complex 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 alternative.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
