Things to Look For in a Window Contractor

Before selecting a window contractor, read about his or her experience, qualifications, certifications, and reputation. Whether you need your windows repaired or replaced, these are important factors to consider. Read this article to make the selection process easier and more enjoyable. Also, remember to ask about any warranties that may apply. Before signing anything, make sure that you’re comfortable with the company’s reputation and warranty information. In addition, you’ll want to make sure that the contractor will honor any manufacturer’s warranty.


One of the most important qualifications for a window contractor is their training and education. A window contractor is required to hold a license to operate as a window contractor. This license may require a fee, examination, or a combination of both. After obtaining their license, they must provide proof of business ownership, management, and liability insurance. Some states also require window contractors to complete continuing education courses and seminars, and many also require window contractors to maintain membership in professional organizations, such as AWDI.

A certification from the Architectural Manufacturers Association (AAMA) is another key requirement of a window contractor. This certification assures prospective customers and employers that an individual has current knowledge of the industry. Interested candidates must complete a rigorous training program and pass an examination testing their skills and knowledge. For example, a window installer who holds an AAMA certification is likely to have completed more than six months of training and has passed a comprehensive knowledge and skills examination.

If you are considering a career as a window contractor, it’s important to know that a high school diploma is not required to start your new job. While a GED certificate is not essential, many employers will prefer a candidate who has taken woodworking and metalworking courses in high school. However, if you want to gain more knowledge and earn more, you can pursue voluntary professional certification through organizations like InstallationMasters. Further training can also help you specialize in different aspects of the industry, such as fire-resistant glazing or window tinting.

A window contractor should meet local building codes. In addition to having the necessary licenses and certifications, they should be insured. They should also own their own truck or van, so you can expect them to come to you equipped with the necessary tools. When interviewing potential window contractors, ask them to show you their licenses and certifications. In addition to these, check if they are bonded. A licensed window contractor will be more likely to provide you with a quote that is competitive and fair.


When looking for a window contractor, remember that many of them are also shoppers. They look for good jobs, a fair profit, and referrals. Some contractors will look to get your business because they have had good experiences with past customers, but they may also look for warning signs of customer problems during the initial interview. In addition, window contractors prefer to work in the community around their homes, so you may want to select a local company if possible.

Not all contractors have all of these credentials. Some cities and states require contractors to be licensed. A business license, however, does not guarantee that a company is competent or reliable. Some companies will simply state that they are licensed, but this is only for tax purposes and does not reflect their true capabilities. Most window manufacturers have programs for contractors, which can help them become more knowledgeable and establish credentials. Having credentials from the manufacturer is also a good sign of professionalism.

After receiving several quotes from window contractors in your area, you should visit their websites and research the reviews posted by their clients. Take note of how quickly they respond to inquiries. You want to ensure that you get a good window contractor with good customer service. A bad window installer might ignore your emails and refuse to provide you with the information you need. Lastly, you should ask about their warranties, if any. A window contractor should be willing to discuss these details with you before starting work.

Finally, make sure the contractor you choose is insured. Workers’ compensation insurance and comprehensive liability insurance are essential. Having these insurances protects you and your home in the event of an accident or mishap. You want to make sure that any windows you purchase come with a warranty. Even if this warranty is short-lived, a good contractor will stand behind their work long after the warranty has expired. And if you hire a window contractor with insurance, it makes sense to choose a company that has an excellent reputation in the community.


Before hiring a window contractor, consider the company’s reputation. Many homeowners make the mistake of slashing costs on replacement windows, but poor workmanship can lead to future problems and costly repairs. The reputation of a window contractor says a lot about its work, and a quick internet search can show you which companies have a good reputation. Listed below are some things to look for in a window contractor. You should also read customer reviews, which will give you a sense of what other homeowners think of the company.

You can also get a sense of a window contractor’s professionalism through word of mouth. Chances are you know someone who recently had their windows replaced. Ask if they can recommend a high-quality window company. If they have had a bad experience, it might be wise to stay away from that company for now. Fortunately, word-of-mouth referrals are still one of the most reliable ways to determine the reputation of a window contractor.

You can also read online reviews of different window contractors. This way, you can get a sense of how satisfied customers are with the quality of their work. Look for companies with high customer satisfaction ratings. Also, check for negative reviews. A company with few reviews may be too new or unreliable to be considered reputable. If you’re unsure about the company’s reputation, you should hire a contractor with a positive reputation.

References and online reviews can also help you evaluate a window contractor’s reputation. Generally, satisfied customers will be more likely to recommend a window installer who has done good work. Checking customer reviews online can also help you spot potential red flags. Ask friends and family members for recommendations. A window contractor with a good reputation has had a proven track record. You may also be able to find online reviews of their work by reading online customer testimonials.


If you’d like to become a window contractor, you may want to get certified. While not required for employment, these certifications may indicate your expertise in the field and could open up new career opportunities. For example, the AWDI offers a professional certification that requires a combination of practical experience, a written exam and a field inspection. Although many employers prefer to hire professionals with experience, you can also get started as an entry-level contractor.

Choosing the right window contractor depends on the type of certifications you look for. First, look for a seal of the ENERGY STAR(r) organization. This seal will tell you whether the window meets the energy-efficiency requirements in your area. Next, check with the National Fenestration Rating Council for information on energy-efficient window units. Finally, if you’re unsure, look for companies certified by the American Architectural Manufacturers Association.

Third-party certifications can help you hire a reputable window installer. The AAMA certification is a good indicator of quality, because it verifies that the contractor has passed rigorous testing. This means that the windows were installed correctly. It also ensures that the window will perform according to the manufacturer’s specifications. It’s not only better for your home, but also your wallet. Therefore, look for AAMA-certified window contractors.

Secondly, look for a company that has a Certified Master Installer program. This program is sponsored by a reputable window manufacturer. Renewal by Andersen is one such company. Certified Master Installer programs are rigorously followed to ensure the quality of installation. These programs also offer ongoing training and review. And if you’re concerned about quality, make sure your window contractor is certified by the manufacturer. The company should also be willing to handle complaints.

AWDI is another reputable certification. The program was initiated by the Building Environment and Thermal Envelope Council and the American Architectural Manufacturers Association. It is a comprehensive training course for windows and exterior glass doors, and aims to improve the quality of installation. As a member of the National Association of Remodeling Industries (NARI), Great Day Improvements is dedicated to helping homeowners make informed decisions when it comes to installing their new windows and doors.
