• Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Hartford

Each window installation company offers various services and has varying prices based on several factors.

How Much Do New Windows Cost?

Typically, homeowners in Hartford can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is because of the fact that 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.

It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Hartford homeowners $502+ a year when replacing single-pane windows.

Something else that influences the total cost is the material you select for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

Your window replacement company will be able to help you figure out what’s best for your needs. In Hartford, the decision will mostly be based on the age of your windows and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.
