Efficient windows are of particular importance in Essex, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $403 each year.

How Installing Energy-Efficient Windows in Essex 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 include the following:
- 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.
- Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Essex
When considering window installation, each company offers different services and costs. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Generally, Essex homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at around $600. Costs will vary considerably depending on your location, the current condition of your home, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $403 a year on your energy bills in Essex.
Something else that influences the total cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won't cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
Your window installation company will be able to help you decide what's best for your needs. In Essex, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Essex
In our hunt to make your home improvements easier and more eco-friendly in Essex, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Essex, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Essex.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher 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 nice things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we awarded higher scores 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 that provide 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Essex, CT Window Replacement FAQs
How much should window installation cost?
The national average cost of installing a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically dependent on the size of the window, the type and material of the window and the location of your property. 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 type of window is the most energy-efficient?
A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window installation companies provide?
Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
How long does window installation generally take?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
Should I replace all my windows at once?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
