Our Choice For Best Window Replacement Company in San Antonio

In our opinion, Renewal by Andersen is the best window installer in San Antonio. This company has been around for over a century and has been providing outstanding customer service and high-quality, durable windows manufactured in-house for just as long. Renewal by Andersen is a highly respected and trusted name in the window industry, and it backs up that reputation with a comprehensive 20-year warranty on windows plus a two-year warranty on workmanship.

A big reason we chose Andersen as the top company in San Antonio is the wealth of energy-efficient options it offers to customers. It manufactures its own windows and maintains a high level of efficiency with all of its product lines. It also offers double-pane and triple-pane glass, Low-E coatings, window tinting and insulative frame materials to help maximize your home’s energy efficiency.

How We Chose the Top Replacement Window Installation Companies in San Antonio

how we chose best window replacement companies in San Antonio

When we evaluate window replacement companies, we do a deep dive into each company and look at quite a few factors that are likely to affect your overall experience with the provider. Below are some of the most important factors that affect our decisions.

Eco-Friendly Options

First, we rule out companies that don’t provide access to energy-efficient window options. These include double-pane and triple-pane windows, Low-E coatings, window tinting, efficient frame materials and more. As an environmentally-friendly website, EcoWatch is most concerned about energy efficiency, and these options can help reduce your electricity usage and your dependence on fossil fuels to cool and heat your home. Ultimately, eco-friendly window installation companies help you reduce your contribution to pollution and global warming.

Less strain on the environment isn’t the only benefit of choosing a company with eco-friendly window options. Better insulation in your windows, which are the least energy-efficient part of your exterior walls, can make your living space more comfortable for you and your family. Poorly insulated windows can allow cold air in during the winter months and out during the summer months.

This also means that replacing your windows can decrease your energy bills, as you’ll have less energy lost to your home’s exterior to make up for with your heating and cooling systems.

Window Brands Available

We give precedence to window companies that manufacture or install only high-quality windows with great durability. A company like Renewal by Andersen, for example, manufactures its own windows and maintains total control over workmanship. Companies like Window World that install windows manufactured by third-party companies are evaluated similarly, but we look at the quality of the brands available overall.

We give a slight preference to companies that have multiple brands available, as this provides the homeowner with some options to balance budget, energy efficiency, curb appeal and personal preference.

Warranty

The warranty offered by a window installer is a crucial factor that we consider very carefully. Replacement windows are expensive, and warranties guarantee that your investment is protected and that the company installing your new windows will do the work properly the first time around.

Window installation companies typically have warranties for the windows themselves, the labor or some combination of the two. Installers that provide lifetime warranties tend to rank higher, as do those that offer warranty coverage for both the work done during installation and the window itself.

We also evaluate customer reviews to see if customers have had issues with companies honoring their warranties. Some less reputable companies might deny warranty claims to save money, and a pattern of this will move them much further down in our rankings.

Pricing and Financing

Any homeowner will be concerned about the price of installing new windows, whether they’re getting one window or every window in their home replaced. Windows and the labor to install them are expensive, so companies who are able to pass savings onto customers will appeal to more homeowners and rank higher in our ratings.

Along with the pricing, we assess the value provided by each company. In some cases, above-average pricing is justified if the durability, warranty and energy efficiency of the products being sold are also above average.

Financing options are also an important factor, so we look for companies that offer in-house financing with a low monthly payment. These companies are more likely to appeal to customers of all financial backgrounds, and they can sometimes make home improvement and energy efficiency possible where it wouldn’t be otherwise. We rank companies higher if they have multiple payment options, no-down-payment loans and other appealing financial plans.

Year Founded

The final major factor we consider is how long the company has been in business. Given the climate in San Antonio, the demand for window replacement is higher than in many other areas. As such, some companies offer window replacement services simply to turn a profit without regard for their customers and overall environmental friendliness. To avoid recommending these companies, we tend to choose those that have longevity and a proven track record.

Additionally, companies that have been around for many years and still maintain customer satisfaction know what they’re doing and prove again and again with each installation that their techs are well-trained. Choosing a company that has years of experience is more likely to leave you satisfied for years to come.

When Should You Replace a Window in San Antonio?

Many homeowners don’t know how to tell when their windows need replacement, so some unknowingly go months or years with drafts, leaks and other issues that can increase their electric bills and damage their property. Below, we’ll discuss three clear signs your windows need to be replaced.

High Energy Bills

window repair draft check

One of the biggest downsides of outdated or damaged windows is an increase in your energy bills. In an area like San Antonio, you might naturally see spikes in energy usage in the summer months because of air conditioner usage. However, it’s wise to compare your electricity consumption every year to the previous year’s bills. If your consumption is higher on average, then you might need to replace your windows.

Windows offer natural light and ventilation along with points of egress, but they also lose more energy to the outside than a solid wall. When your windows age, they become less and less insulative, which can lead to air leaks that your heating and cooling systems need to compensate for. Installing new windows can instantly reduce your energy bills by quite a lot.

Poor Window Operation

Another clear sign that your windows need to be replaced is poor window operation. Windows have a bunch of moving parts, including sliding sashes, locking mechanisms, tilting mechanisms for easy cleaning, window balances and more. As your windows age, these mechanisms and pieces can degrade and fail.

If you notice windows getting stuck open or closed, windows that won’t lock, sashes that slam down when you open them or tilting mechanisms that no longer function, it’s probably time for a new window. Many of these issues aren’t too serious on their own, but they are signs that your windows are getting older, which means replacement will likely benefit you and your home.

Damaged, Rotting or Moldy Frames

If you find physical damage to your window frames, like cracking, chipping or peeling, these are indications that your windows need to be replaced. These can often just come about from old age, but aging windows are prime candidates for replacement.

More serious issues include rotting and mold formation around your windows. If you notice discoloration, water stains or mold spores near your windows, especially around the bottom, you should call a window contractor immediately. These are clear signs of water getting through your window, which means the seal has been compromised, and your property is exposed to the elements. Water intrusion through your windows can lead to much more severe damage, so it’s essential to remedy these issues immediately.

What to Look For When Choosing a Window Installation Company in San Antonio

If you’re still unsure which window installer is right for you and you want to keep searching, there are a few things you should look for in a company before deciding. We’ll discuss these criteria below to help make your decision a bit easier.

New Construction or Replacement

One of the easiest ways to rule out some window installers is to look to see if they handle new window installation and replacements or just replacements.

A new window installation involves framing the window and installing it from scratch in new construction. It can also mean installing a window where there wasn’t one previously or installing a new window that’s larger than the old window. This process is more complicated than swapping one window for another of the same size, so you might be able to rule out some companies that don’t offer this service if you need it.

Window replacement either involves installing new sashes in an existing frame or replacing an entire window with a new one without altering the existing wall. This process is much simpler than new install and often cheaper, and any window installer should be able to handle it.

Window Style

Not all window installation companies handle every window style. Most will be able to install the common styles, like double-hung windows, single-hung windows, picture windows and casement windows. However, if you have specialty windows, uncommon sizes or just uncommon styles — like round windows, skylights, garden windows and others — you might have more difficulty finding a company that can replace them for you.

It’s a good idea to check what styles a company can tackle before getting too far into the research process.

Materials

Window frames and window glass come in many different options with varying costs and levels of energy efficiency. It’s worth looking at what a company offers in terms of materials before committing to it for your window replacement project.

For example, some homeowners want wood frames to match existing windows or to achieve a specific curb appeal. Others might prefer vinyl windows for their affordability and improved energy efficiency. Customers looking for the highest level of efficiency — like many who deal with San Antonio’s extreme summer heat — might prefer fiberglass or composite, despite the higher up-front cost. You can often rule out some companies based on the frame materials they offer.

Similarly, there are quite a few glass options and coatings you can choose, depending on your window installer. Double-pane glass with an insulative layer of argon gas is a popular energy-efficient choice, but many homeowners in Texas prefer triple-pane glass with krypton gas for maximum thermal insulation. Low-e coatings and tinting can also provide added protection from the sun and heat. Not every company carries these options, so ask your provider before committing.

Scheduling & Consultation

San Antonio is a relatively busy city, and the population has increased significantly over the past few decades.1 The demand for window replacement is high, and some companies struggle to keep up with demand. You might want or need to shop around for a company with an easy scheduling process and open availability to get your project done in a timely manner.

Additionally, you should consider what types of consultations are available. Many — but not all — companies offer in-home and virtual consultations to provide you with free quotes and maximum convenience.

Financing

Most window companies provide financing options for homeowners to make home renovations more accessible. If you’re looking to finance your window project, you can limit your company search based on those that have in-house options with low monthly payments that suit your budget. Choosing a company with an easy and immediate approval process will also make your life a bit easier.

Warranty

Warranties for windows are essential for maximizing your peace of mind after spending thousands on new windows. Warranties from window installers often cover the equipment or workmanship, and some companies offer coverage for both. Although companies with lifetime and comprehensive warranties are sometimes more expensive, they can save you money in the long run by limiting your recurring expenses for fixing issues after installation.

Online Reviews

Finally, you should read through some online reviews of a window installation company before committing. Customer reviews on websites like Google Reviews and the Better Business Bureau can paint an unbiased picture of what you can expect from the company. Negative reviews will highlight the potential downsides of working with a company, and positive ones will show you where the provider shines.
