Whether you're doing home renovations or have old windows, windows play a crucial role in conserving your home's energy. The Department of Energy estimates that heat or cool air lost through outdated or drafty windows could make up around 30% of residential energy climate usage. In Lancaster, where the electricity bills are an average of $35 per month, that's almost $$126 per year wasted.

That's bad news for both your bank account and the environment, but one of the top window installation companies can help you with that.

Efficient windows are particularly important in Lancaster, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $482 a year.

How Installing Energy-Efficient Windows in Lancaster Saves You Money

When you switch to energy-efficient windows, you may see a few perks, including:

  • Save on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your house.
  • 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.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 139 pounds per year on average.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Lancaster

Each window installer provides various services and has different costs based on a few factors.

How Much Do New Windows Cost?

Typically, homeowners in Lancaster can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Something else that affects the overall cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. Full-frame installations are more involved and will increase the overall cost. A pocket installation involves replacing a window without removing the complete frame, which is generally cheaper than a full-frame installation.

If you're unsure which kind of window installation service you need, your installer can assist you. In general, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lancaster

In our hunt to find the most reliable, eco-friendly window installers in Lancaster, the EcoWatch team assessed dozens of companies before settling on these. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Lancaster, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Lancaster.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, cost, quality of parts, quality of installation, warranty and more.

Cost

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

Warranty

As discussed previously, 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 labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Lancaster, MA Window Replacement FAQs

How much should window installation cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally dependent on 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 hundreds of dollars a year in energy bills.

Which kind of window should I get?

A window's energy efficiency is influenced by a number of factors, including 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 since they are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installers go to your property to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.

How often should you replace your windows?

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

Should I replace my windows all at once?

If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
