Estimated Cost of Window Replacement in Guilford

When researching window installation, each company offers varying services and costs. Let’s look at some average costs and services.

How Much Do New Windows Cost?

According to our market research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. Costs will vary considerably based on your location, the quality of your products, the current condition of your home and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Guilford homeowners $420+ a year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

If you’re still debating which type of installation to get, you can consult with your provider and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Guilford

EcoWatch reviews are different from other reviews because we assess these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Guilford and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Guilford so you can find the best window installation company near you.

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like 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. That’s why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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