How Installing Energy-Efficient Windows in Colchester Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, such as:
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save money on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Colchester, that’s about 147 pounds per year on average.
Estimated Cost of Window Replacement in Colchester
When looking into window installation, each company provides different services and prices. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Typically, Colchester homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. This is because window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you want energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $424 a year on your energy bills in Colchester.
Another factor that influences the total cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive 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?
When considering window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the whole window, including the frame, trim and sill. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Colchester, the decision will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Colchester
EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Colchester, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Colchester.
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 in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Colchester, CT Window Replacement FAQs
How much should window installation cost?
The average cost of installing a single window can range from $450 to $650. There are many factors that affect how much it costs, such as local labor costs, styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows, the number of windows and your property’s location.
Which kind of window should I get?
A window’s energy efficiency is influenced by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Can you install your 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. Hiring a professional can help guarantee that the job is done properly and that you won’t have to spend the time and effort to do it yourself.
When is it time to replace your windows?
Windows typically have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to determine if they are in need of a repair or replacement.
How long does it typically take to install windows?
Because a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.
