Harwinton Window Cost Calculator

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

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

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Harwinton Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, such as:

  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Better temperature control in your home: Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Harwinton

When looking into window installation, each company provides varying services and costs. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Though the typical of installing one window is around $600, it can range from $200 to $1,200. But costs will differ considerably based on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Harwinton home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your professionals will replace the complete window, including the sill, frame and trim. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Harwinton

In our search to make your home improvements easier and more eco-friendly in Harwinton, the EcoWatch Reviews team evaluated dozens of companies before settling on these. Along with energy efficiency, we reviewed several window installers in Harwinton and ranked them based on the following methodology:

Service Area

Because this is a guide for Harwinton, we only included companies that provide services to the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Harwinton.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you choose. 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

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers may not 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. For that reason, window installation companies that have lengthy warranties for products, parts and labor 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.
