How Installing Energy-Efficient Windows in Glasgow Saves You Money

Upgrading 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:

• Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 612 pounds.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Glasgow

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

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, including size, type, material, the location of your home, number of windows and more.

It’s also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Glasgow home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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?

Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Glasgow

EcoWatch is different from most reviewers, as we assess these companies through a sustainability lens. We have reviewed the best window installation companies in Glasgow mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Glasgow, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Glasgow.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, professionalism, warranty, quality of installation, cost and more.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Due to Glasgow’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Glasgow window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
