How Installing Energy-Efficient Windows in Waltham Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
• Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

How Much Do New Windows Cost?

On average, homeowners in Waltham can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600.

Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $464 a year on your energy bills in Waltham.

We advise requesting free quotes from several window installers to find the one that works best for you.

What Services do Window Installers Offer?

In regard to window replacements, there are generally two kinds that your installer will have: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. These installations are more involved and will increase the overall cost. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Waltham

In our hunt to make your home improvements easier and more eco-friendly in Waltham, EcoWatch examined dozens of companies before deciding on these. Along with energy efficiency, we analyzed several window installers in Waltham and assigned rankings based on 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 best window installation company near you.

Work Quality

When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that offer 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 good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
