How Installing Energy-Efficient Windows in North Haven Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $420 annually on your energy bills in North Haven.
- Protect your valuables: Many energy-efficient 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.
Estimated Cost of Window Replacement in North Haven
Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in North Haven can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost is based on several factors, like type, number of windows, size, the location of your home, material and more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save North Haven homeowners $420+ each year after replacing single-pane windows.
We advise getting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
In regard to window installations, in general there are two types that your provider will have: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely 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.
If you’re unsure which type of window installation service you need, your installer can help you out. Generally, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in North Haven
In our search to make your home improvements easier and more eco-friendly in North Haven, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for North Haven, we only included companies that cover the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in North Haven.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type 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 very important review factor is customer feedback. If most customers don’t have positive 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: similar to other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor 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 earn higher rankings by our standards. We like to see at least ten years of experience.
North Haven, CT Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, depending on several factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your house, including picture windows, transom windows, slider windows, awning windows, bay windows, double-hung and single-hung windows and casement windows.
Can I replace my own windows?
If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend hiring a professional.
Should I replace all my windows at the same time?
If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to gain that benefit. However, if you have only one or two windows that are broken or drafty, you can replace just those.
