Griswold Window Cost Calculator

How Installing Energy-Efficient Windows in Griswold 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 valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Griswold

Windows come in different styles, shapes and purposes, so costs and services will vary remarkably based on several factors. Below, we go over the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Typically, Griswold homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These estimates vary based on the specifics of your installation, like the location of your home, size, material, number of windows, type and more.

It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Griswold home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your provider will have: 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 to change the style of your windows or your window has considerable rot. These installations are more involved and will increase the overall cost. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Griswold, the decision 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 Griswold

EcoWatch reviews are different from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

Service Area

Since this is a guide for Griswold, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Griswold.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Griswold, CT Window Replacement FAQs

What is the typical cost to install new windows in a home?

The average cost of installing one window can range between $450 and $650. There are several factors that influence the cost, which include styles and sizes of windows, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs and your property’s location.

What are the most common kinds of replacement windows?

There are several different kinds of windows you can get for your house, such as bay windows, transom windows, slider windows, double-hung and single-hung windows, picture windows, awning windows and casement windows.

What services do window replacement companies do?

Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up afterward. In addition, a lot of companies offer window manufacturing, customization and repairs.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
