How Installing Energy-Efficient Windows in Williamstown Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, including:

  • 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 fading of your furniture, carpet and other valuables.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
  • Better temperature control in your home: Living in a cold city like Williamstown often means needing your heater to keep your house cool. Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help lower that amount, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Williamstown

When looking into window installation, each company provides different services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Generally, homeowners in Williamstown can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.

It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Williamstown homeowners $524+ a year when replacing single-pane windows.

We recommend getting free quotes from multiple window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

When it comes to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Full-frame installations are more involved and will raise overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're still debating which type of installation you should get, you can consult with your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Williamstown

EcoWatch is different from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Williamstown and ranked them using the following methodology:

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 right window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have nice feedback about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a sizable 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

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Williamstown, MA Window Replacement FAQs

How much does window installation cost?

The average cost of replacing a single window ranges between $450 and $650. There are many factors that influence how much it costs, which include local labor costs, the materials used in designing the windows, the number of windows, your property's location, how energy-efficient the windows are and styles and sizes of windows.

What are the most common kinds of replacement windows?

There are several different types of windows you can get for your home, such as transom windows, bay windows, slider windows, picture windows, awning windows, double-hung and single-hung windows and casement windows.

Do I really have to use a window installation company?

You should hire a window installation company whenever you want new windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best handled by the professionals.

How long does it typically take to install windows?

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 have a lot of windows that must be installed.
