Why you can trust EcoWatch
Whether you're updating for aesthetics or have old windows, windows play a crucial role in conserving your home's energy. If you have outdated, drafty windows, your AC or heating system could be working overtime to heat or cool your house. This means spending more on electricity bills.
That's also bad for the environment because the additional energy used by drafty windows increases your carbon footprint.
Efficient windows are particularly important in Dallastown, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $315 a year.

How Installing Energy-Efficient Windows in Dallastown Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
- More efficient energy usage in your household: Because the summers can get quite hot in Dallastown, homeowners usually rely on their air conditioner during that time. Energy-efficient windows decrease the amount of cool air that is lost through your windows, making it easier to keep your house cool.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
Estimated Cost of Window Replacement in Dallastown
Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
According to our market research, the national average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost you is based on several factors, including material, number of windows, size, type, the location of your home and more.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material you choose for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you're still debating which kind of installation you need, you can consult with your provider 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 Dallastown
In our search to find the most reliable, eco-friendly window installers in Dallastown, the EcoWatch team assessed many companies before landing on these. We have decided to assess the top window installation companies in Dallastown mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Dallastown so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to ensure its contractors are well-qualified and that the company has gotten tons 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 good feedback about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Dallastown's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Dallastown window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
