Replacing old windows these days is complex. It is essential to find the right window installation team in 2026 to combat rising costs, changes in Minnesota’s regulations, and labor delays.
To help you perform due diligence and gain maximum return on your investment, use this handy list of 14 questions to ask prospective window installers.
Ask Smart Questions to Receive Maximum Value from Your Investment
Use this list to select a professional window team whose precision installation techniques deliver lasting results you can count on.
1. How long have you been in business?
Knowledgeable companies ensure windows are replaced properly, eliminating future problems. Make sure the installer is local, experienced, and uses team members (not subcontractors) who are invested in your project’s outcome.
2. Which window manufacturers do you recommend, and why?
With renovation costs rising, it is crucial to seek high-performing windows that provide efficiency, security, and beautiful views. Ask about features, styles, and colors.
3. What special features, if any, do my windows need?
In the Twin Cities, many homeowners prefer features like argon fills between panes for added insulating value. Personalized needs, such as shatterproof glass, childproof locks, or privacy glass, should also be discussed.
4. How do you handle estimates, contracts, and payments?
Reputable companies put everything in writing. Ask for materials and labor to be detailed on your estimate. Trustworthy installers ask for a down payment, not 100% upfront.
5. What experience do you have with houses like mine?
This is key if your home is historic or has unique needs. Look at galleries of their work. Ensure they show understanding of your local homeowners’ associations and historical requirements.
6. Do you have up-to-date licensing and insurance?
Insurance, licensing, and certifications help reduce your risk of costly liability issues. Find companies that stay in sync with Minnesota’s regulations, so you can successfully pass inspections.
7. Who performs the windows installation?
To protect yourself from miscommunications, poor workmanship, and other problems, choose a company that directly employs the installation team rather than using subcontractors.
8. How will you ensure my windows fit properly?
Mistakes in sizing can create costly delays or lead to windows that do not properly prevent leaks. Look for a contractor that performs multiple checks on measurements. Their estimate or process notes should mention spray foam insulation and caulking to keep your house free of drafts and moisture intrusion.
9. What steps will be taken to protect my house?
Window replacement can stir up dust and create debris. Reliable companies provide solutions (like drop cloths inside and atop landscaping) to keep your property safe. Double-check that they handle disposal of old windows.
10. Who handles permits and inspections?
Without permits, occupancy and house sales can be delayed. Experienced contractors know when permits are required. Find out who gets the permit, how it is paid for, and who schedules inspections to approve the work.
11. Can you provide examples of recently completed installations?
Review the company’s project gallery to see the quality of their work. Look for positive ratings on Angi, the BBB, and other review sites. Ask past customers about the contractor’s timeliness, responsiveness, professionalism, and follow-through.
12. What guarantees come with your window installations?
Understanding your warranty protects you in case materials fail or installations go awry. Professional window teams take pride in their craftsmanship and want satisfied homeowners. They often offer labor guarantees and extended warranties.
13. What kind of timeline can I expect?
To minimize price fluctuations and streamline material delivery, your installation’s timeline is important. Learn how soon the project can begin, how many days it will realistically take, and how scheduling is arranged.
14. How are unexpected delays, changes, and mishaps handled?
While the goal is to have your window installation go perfectly, the unexpected can happen. Bad weather may cause delays, materials might get backordered, and so on. Find out how a company handles the unexpected and ensures the process goes smoothly and to your satisfaction.
