How Installing Energy-Efficient Windows in Markham Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on power bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Markham

When looking into window installation, each company provides different services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Markham can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which have a higher price tag.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing 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 type of window material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are 100% 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?

In general, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the total window, including the trim, frame and sill. A pocket installation involves replacing a window without removing the entire 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 Markham, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Markham

The EcoWatch Reviews team differs from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state 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 Markham area so you can find the best 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 included on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have positive feedback about their experience with a certain installer, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as 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. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Markham's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Markham window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Markham, IL Window Replacement FAQs

What is the average cost to install windows?

The typical cost of replacing one window ranges from $450 to $650. There are many factors that affect how much it costs, which include styles and sizes of windows, the number of windows, how energy-efficient the windows are, the materials used in designing the windows, local labor costs and your property's location.

What kind of window is the best for energy efficiency?

A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

When should I use a window installation company?

You should use a window installation company whenever you need to replace your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.

How long does window installation generally take?

Each window takes around 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 need to be installed.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
