How Installing Energy-Efficient Windows in Laconia Saves You Money
By switching to energy-efficient windows, you and your family can benefit in several ways, such as:
- Reduce your carbon footprint: In Laconia, you can cut your indirect greenhouse gas emissions by about 152 pounds per year after you install energy-efficient windows.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save around $492 annually on your energy bills in Laconia.
Estimated Cost of Window Replacement in Laconia
When researching window installation, each company provides different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
According to our market research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. These estimates are based on specific characteristics of your installation, like material, number of windows, size, the location of your home, type and more.
Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts 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. These savings vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two types of window installation services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has noticeable rot. Full-frame installations are more involved and will increase the overall cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
If you're still debating which type of installation to get, you can talk to your provider and get their advice. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Laconia
In our hunt to find the most reliable, eco-friendly window installers in Laconia, EcoWatch examined dozens of companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, cost, professionalism, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide 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 make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Laconia's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Laconia window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Laconia, NH Window Replacement FAQs
What is the typical cost to install windows?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
A window's energy efficiency is affected by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installers do?
Window installation professionals visit your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How often do you need to replace your windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
Should I replace my windows all at the same time?
If you're upgrading your windows to save on your energy bills, replacing all your windows at the same time 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.
