Why you can trust EcoWatch
A guide on the best window replacement companies in Madison may not seem like the most riveting article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize.

Replacement windows improve the insulation in your home, not only making you more comfortable during the summer and winter, but also saving you some money and helping the environment.
Unlike other review sites, EcoWatch ranks window installation companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Madison Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, 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.
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Better temperature control in your home: Residing in a very cold place like Madison usually means depending on your heater to keep your house cool. Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in Madison
Windows come in various shapes and sizes, so costs and services will differ considerably. 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?
Though the typical of installing one window is about $600, it can range from $200 to $1,200. Costs will differ significantly depending on the quality of your products, your location, the number of windows you need and the current condition of your home. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step of a window installation is to clarify whether you want a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation entails replacing a window without taking out the complete frame, which tends to be less expensive than a full-frame installation.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Madison, the decision will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Madison
EcoWatch reviews are different from most reviews because we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer 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 the Madison area so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
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 service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Madison's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Madison window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
