Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

The EcoWatch Reviews team is all about finding solutions for eco-conscious homeowners in Guilford. The Department of Energy estimates that heat or cool air lost through old or damaged windows could be responsible for nearly 30% of heating and cooling use. In Guilford, where the energy bills are an average of $33 per month, that's almost $$117 per year wasted.

That's also bad news for the environment, as the additional energy used by drafty windows increases your carbon footprint.

Efficient windows are particularly important in Guilford, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $304 each year.

How Installing Energy-Efficient Windows in Guilford Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Guilford

Let's take a look at the cost of window installation and the kinds of services you may need for your home.

How Much Do New Windows Cost?

The typical cost to install one window is about $600 but can range from $200 to $1,200. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which carry a higher price tag.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $304 a year on your energy bills in Guilford.

Getting free quotes from several companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

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

How We Choose the Best Window Installers in Guilford

In our hunt to make your home improvements easier and more eco-friendly in Guilford, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have decided to review the best window installation companies in Guilford mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Guilford, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Guilford.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you choose. 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 very important review factor. If the majority of customers don't have good things to say about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when 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 serious investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Guilford's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Guilford window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Guilford, PA Window Replacement FAQs

What is the typical cost to install windows?

The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on several factors. The price is often influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window is the best?

A window's energy efficiency is influenced by a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

When do I need to use a window installation company?

Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.

When is the best time of year to replace windows?

Although you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, it shouldn't be raining, since rain can make the installation harder.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
