Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house’s energy efficiency can also have a large impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through outdated or drafty windows could make up close to 30% of heating and cooling costs. In Glasgow, where the energy bills are an average of $33 per month, that’s almost $$119 per year wasted.

That’s not great for either your bank account or the environment, but one of the top window installation companies can help you with that.

So if you’re constructing a new home, renovating or updating your windows in Glasgow, you’ve found the best place to get started.

How Installing Energy-Efficient Windows in Glasgow Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Glasgow, that’s about 299 pounds per year on average.
  • Save on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.

Estimated Cost of Window Replacement in Glasgow

When considering window installation, each company offers varying services and prices. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

On average, homeowners in Glasgow can expect that most window installations will cost between $250 and $1,200, with the average cost at about $600. But costs will differ considerably based on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

Bear 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 you install single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

We advise getting free quotes from several window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

In general, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the whole window, including the sill, trim and frame. A pocket installation involves replacing a window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation you need, you can ask your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Glasgow

The EcoWatch Reviews team is different from most reviewers because we assess these companies through a sustainability lens. We have evaluated the top window installers in Glasgow mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. 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

Since this is a guide for Glasgow, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Glasgow.

Work Quality

When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we gave 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 that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Glasgow, DE Window Replacement FAQs

How much should window installation cost?

The average cost of installing a single window ranges from $450 to $650. There are several factors that affect the cost, including how energy-efficient the windows are, your property’s location, the materials used in designing the windows, local labor costs, the number of windows and styles and sizes of windows.

What are the kinds of windows?

There are various types of windows you can get for your home, such as double-hung and single-hung windows, bay windows, picture windows, transom windows, slider windows, casement windows and awning windows.

Can you replace your own windows?

Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.

How long does it take to install windows?

Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
