How Installing Energy-Efficient Windows in Stony Brook Saves You Money

There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Installing energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Stony Brook

Windows come in all shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you'll find from the average window installation company.

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. Costs will vary considerably depending on the quality of your products, your location, the number of windows you need and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.

It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that upgrading the windows on your Stony Brook 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. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they entail merely 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.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Stony Brook, the decision will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Stony Brook

EcoWatch reviews differ from other reviews since we're examining these companies through a sustainability lens. We have evaluated the top window installation companies in Stony Brook primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has gotten 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 positive things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Stony Brook, NY Window Replacement FAQs

What is the average cost to install new windows?

The typical cost of installing a single window can range from $450 to $650. There are a variety of factors that influence how much it costs, which include the materials used in designing the windows, local labor costs, styles and sizes of windows, your property's location, the number of windows and how energy-efficient the windows are.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installation companies cover the entire process — from replacing your old windows with brand new ones to cleaning up after the installation. In addition, a lot of companies offer window manufacturing, customization and repairs.

How long does window installation take?

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
