How Installing Energy-Efficient Windows in Alvin Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: In Alvin, you can reduce your indirect greenhouse gas emissions by about 507 pounds per year when you upgrade to energy-efficient windows.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Alvin

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

How Much Do New Windows Cost?

Though the average cost of installing a single window is around $600, it can range anywhere from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Alvin homeowners $314+ a year when replacing single-pane windows.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide 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 provide decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window installation is to think about whether you need a full-frame or pocket installation.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations are simpler and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

If you’re not sure which window installation service you should get, your installer should be able to help you out. Generally, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Alvin

The EcoWatch Reviews team differs from most reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:

Service Area

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

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, warranty, professionalism, quality of parts, quality of installation and more.

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 the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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

Alvin, TX Window Replacement FAQs

How much should window installation cost?

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

Which kind of window is the best?

A window’s energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you install your own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or know-how, we don’t recommend it.

Should I replace my windows all at once?

If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.

How long does it typically take to install windows?

Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
