How Installing Energy-Efficient Windows in Plano Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, such as:

• Save on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Plano, that’s about 642 pounds per year on average.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Plano

Windows come in various purposes, styles and shapes, so costs and services will vary tremendously depending on several factors. Below, we go over the typical cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

On average, homeowners in Plano can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at around $600. How much it will cost is based on several factors, like size, material, number of windows, type, the location of your home and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Plano homeowners $307+ per year after replacing single-pane windows.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are simpler and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installation company will be able to advise you on the best type for your project. In Plano, the choice will mostly depend on how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Plano

In our search to make your home improvements easier and more eco-friendly in Plano, the EcoWatch team examined dozens of companies before deciding on these. We’ve decided to assess the top window installers in Plano mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Plano, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Plano.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have nice 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 gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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