How Installing Energy-Efficient Windows in Hartford Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: In Hartford, you can lower your indirect greenhouse gas emissions by about 147 pounds per year after you install energy-efficient windows.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Hartford

When looking into window installation, each company provides varying services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Generally, Hartford homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. Costs will vary considerably depending on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

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 $446 a year on your energy bills in Hartford.

Something else that influences the overall cost is the material you choose for your frame. Aluminum frames are typically the least expensive 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 provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when considering a replacement is to figure out whether you need a full-frame or pocket installation.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are simpler and won’t carry as large a bill, as 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.

Your window installation company can recommend the best type for your project. In Hartford, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

In our search to find the most reliable, eco-friendly window installers in Hartford, EcoWatch assessed dozens of companies before settling on these. We’ve decided to evaluate the best window installers in Hartford mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Hartford area so you can find the best window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company included on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have positive things to say about their experience with a certain window installation company, 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 as low as possible. When analyzing providers’ prices, we awarded higher points 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Hartford’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Hartford window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
