How Installing Energy-Efficient Windows in Concord Saves You Money

When you switch to energy-efficient windows, you may see some benefits, including:

  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
  • Reduce your carbon footprint: In Concord, you can reduce your indirect greenhouse gas emissions by about 286 pounds per year after you install energy-efficient windows.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Concord

Each window installer offers varying services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

Though the average cost of installing a single window is about $600, it can range anywhere from $200 to $1,200. But costs will vary considerably depending on your location, the number of windows you need, the quality of your products and the current condition of your home. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

It’s also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Concord home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window within the existing frame. This means instead of removing the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation you need, you can talk to your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Concord

EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. We’ve evaluated the top window installers in Concord mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Concord, we only included companies that cover the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Concord.

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 in our guide to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain company, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that have 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 proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Concord, PA Window Replacement FAQs

What is the average cost to install windows?

The national average cost to install a window is about $600 but can range between $200 and $1,200, based on several factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the different types of windows?

There are various kinds of windows you can get for your house, including transom windows, bay windows, slider windows, double-hung and single-hung windows, picture windows, casement windows and awning windows.

When do I need to use a window installation company?

You should use a window installation company whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best left to the professionals.

Should I replace my windows all at once?

If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.

How long does it usually take to install windows?

Because the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.
