Old Saybrook Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Old Saybrook, CT using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

How Installing Energy-Efficient Windows in Old Saybrook Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Old Saybrook, that’s about 147 pounds per year on average.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Old Saybrook

Windows come in different shapes, purposes and styles, so costs and services will vary tremendously based on several factors. Below, we detail the average cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

According to our research, the typical cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will add extra costs to your project.

It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Old Saybrook homeowners $403+ a year when replacing single-pane windows.

The cost of your window installation 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 somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage. Because these installations are more involved, they will raise the total cost. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company will be able to advise you on the best type for your project. In Old Saybrook, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Old Saybrook

In our search to make your home improvements easier and more eco-friendly in Old Saybrook, EcoWatch chose the above companies as the top window installation companies in the city. We’ve assessed the top window installers in Old Saybrook primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Old Saybrook, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Old Saybrook.

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 on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of installation, warranty, quality of parts and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Old Saybrook’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Old Saybrook window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Old Saybrook, CT Window Replacement FAQs

What is the average cost to install windows in a home?

The national average cost of replacing a window is around $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the most common kinds of replacement windows?

The most common types of windows for homes are double-hung and single-hung windows, casement windows, slider windows, picture windows, awning windows, transom windows and bay windows.

Can I install my own windows?

Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

How long does it usually take to install windows?

Since a window takes about 30 minutes to install, about 16 windows can be installed in an 8-hour work day.
