Choosing the right window contractor is absolutely essential. Proper window installation is essential to the longevity of windows in Minneapolis. Windows that are poorly installed won’t have the durability to hold up against the elements. Plus, windows that aren’t installed correctly tend to cause air leakage, leading to higher energy costs. 

If you need replacement windows, your choice of contractor will impact how your new windows look, operate, and hold up after years of use. The window contractor that you opt to work with isn’t a decision to take lightly, and there are many factors to take into account. 

For optimal window performance, you’ll need an experienced, trained, and qualified window contractor. Your experience throughout the window installation process should be a pleasant one, with clear communication and friendly service throughout. 

As you seek out a company to complete your window installation project, look for the following qualities:

Licensed, Insured, and Bonded Window Contractor

Before you settle on a window contractor, ensure that they’re licensed and insured. By having a license, a window contractor proves that they have the basic skills to complete the job and will comply with the building codes in your area. 

In addition to a license, your window contractor needs to be insured. The contractor’s worker’s compensation insurance protects you in the instance that a team member gets injured on the job. The liability insurance offers financial protection if the contractor damages the window during the installation process. With an insured contractor, you wouldn’t be responsible for the cost of the damaged window in this case. 

Bonded window contractors will cover the cost of window installation services from a new company if their work is poor. Additionally, they’ll cover the cost of hiring a new window company to complete the job if their company goes under mid-project. These scenarios aren’t likely to happen, but the risk is always there. So, look for a window company that’s licensed, insured, and bonded. 

Excellent Customer Service

Insight into the quality of your experience with a window contractor will be the customer service, right off the bat. If you’re able to quickly and easily get in touch with a customer service representative to get more information, it’s a sign that the company is organized. If the team is friendly, helpful, and straightforward, it’s another indicator that the company prioritizes its customers. 

No False Claims

These days, with the breadth of advertising that consumers are exposed to every day, companies have the ability to mislead. So, don’t simply trust the advertising materials put out by a window company. Follow up with them to fact-check their claims. If any of the advertising is misleading or not backed up by fact, seek out a different contractor. Making false claims is a poor business practice and a sign that the company isn’t up to scratch. 

Transparent Bids

Bids from potential window installation companies provide helpful information. The bids should be clear and comprehensive. Be wary of hidden costs, such as a disposal fee. Should there be any part of the bid that isn’t clear to you, be sure to ask the company about it. It’s also worth it, at this point, to ask about warranties, as a warranty can protect your investment in new windows.  

Window Contractor Certifications

Certifications from large manufacturers are a great sign that a Minneapolis window contractor is an expert in the field. Training and expertise in specific window products come along with certifications, meaning that most of the top window companies will have them. 


While many assume that cleaning up after a window installation project is a given for professional contractors, you may be surprised at the range of quality in window services. While you’re vetting for a window installation company, ask them about their clean-up process and how they’ll handle your old windows. This will give you an idea of what you can expect after the windows are installed, as well as offer a sense of the company’s professionalism.
