How Installing Energy-Efficient Windows in Lock Haven Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, including:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Better temperature control in your home: Living in a very cold city like Lock Haven can often mean depending on your heater to keep your home cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Better temperature control in your home: Living in a hot place like Lock Haven usually means depending on your AC to keep your house cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
Estimated Cost of Window Replacement in Lock Haven
When considering window installation, each company offers varying services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
On average, homeowners in Lock Haven can expect that most window installations will range from $250 to $1,200, with the average cost at about $600. Costs will vary significantly depending on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase overall project costs.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lock Haven homeowners $333+ a year after replacing single-pane windows.
Costs will also vary depending on the material you want for your window frames. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering a window installation is to decide whether you should get a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the total window, including the frame, trim and sill. A pocket installation involves replacing a window without taking out the complete frame, which is generally less expensive than a full-frame installation.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Lock Haven, the choice will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Lock Haven
In our hunt to find the most reliable, eco-friendly window installers in Lock Haven, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Lock Haven, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Lock Haven.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Lock Haven's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Lock Haven window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Lock Haven, PA Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on 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 initially but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
