How Installing Energy-Efficient Windows in Bay City Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could benefit you:

  • Reduce your carbon footprint: In Bay City, you can reduce your indirect greenhouse gas emissions by about 507 pounds per year when you switch to energy-efficient windows.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that amount, which helps you save more on your bills.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Bay City

Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. These estimates vary depending on the specifics of your installation, including number of windows, the location of your home, material, type, size and more.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Bay City homeowners $327+ per year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using 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 provide decent insulation for your home.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

If you’re still debating which kind of installation to get, you can talk to your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Bay City

In our search to find the most reliable, eco-friendly window installers in Bay City, the EcoWatch Reviews team evaluated dozens of companies before deciding on these. We have evaluated the top window replacement companies in Bay City mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Bay City so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services often plays 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 positive things to say about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Bay City, TX Window Replacement FAQs

What is the typical cost to install windows in a home?

The national average cost of installing a window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is often dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

The most common types of windows for homes are bay windows, picture windows, double-hung and single-hung windows, casement windows, awning windows, slider windows and transom windows.

What services do window installation companies offer?

Window installers will do the entire process — from replacing your old windows with new ones to cleaning up afterward. Additionally, many companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all your windows together is the only way to gain that benefit. However, if you have just a few windows that are broken or leaky, you can replace just those.
