How Installing Energy-Efficient Windows in Milford Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Reduce your carbon footprint: By using less energy after you switch to energy-efficient windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: When you upgrade 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: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
Estimated Cost of Window Replacement in Milford
Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you'll find from window installation companies.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is because window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
It's also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Milford home translates to an average energy savings of $236 to $319 each 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.
Another factor that affects the total cost is the material of the frame you choose. 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, as 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 a window installation is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations are on the simpler end and won't carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
Your window installation company will be able to help you decide what's best for your needs. In Milford, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Milford
In our hunt to find the most reliable, eco-friendly window installers in Milford, the EcoWatch team evaluated many companies before settling on these. We have reviewed the best window replacement companies in Milford mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Milford, we paid more attention to companies that serve 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 Milford.
Work Quality
When picking new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand 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
Customer feedback is another very important review factor. If the majority of customers don't have good things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other 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
As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Milford's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Milford window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Milford, CT Window Replacement FAQs
What is the average cost to install new windows?
The average cost to replace a single window ranges between $450 and $650. There are several factors that affect how much it costs, including your property's location, the materials used in designing the windows, styles and sizes of windows, the number of windows, local labor costs and how energy-efficient the windows are.
Which type 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 often the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window installation companies do?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
How often do you need to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
