How Installing Energy-Efficient Windows in Conway Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- More efficient energy usage in your household: Because the summers can get pretty warm in Conway, homeowners often depend on their air conditioner during that time. Energy-efficient windows lower the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
- Save money on electricity bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $521 annually on your energy bills in Conway.
- 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Conway
Each window replacement company provides varying services and has varying costs depending on several factors.
How Much Do New Windows Cost?
Even though the typical of replacing one window is about $600, it can range anywhere from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Conway homeowners $521+ per year after replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including 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 means replacing a window without removing the whole frame, which is usually cheaper than a full-frame installation.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Conway, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Conway
In our hunt to find the most reliable, eco-friendly window installers in Conway, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed several window installers in Conway and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Conway so you can find the right window installation company near you.
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 featured 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
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, cost, warranty, quality of parts, professionalism and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety 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 protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Conway, NH Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
There are several different types of windows you can get for your house, such as transom windows, awning windows, double-hung and single-hung windows, slider windows, picture windows, bay windows and casement windows.
When do I have to use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all the windows together is the only way to gain that benefit. However, if you have just one or two windows that are broken or leaky, you can replace just those.
