Replacing or installing new windows is a big investment, and choosing the right installer can make all the difference. The last thing you want is poor workmanship that leads to drafts, leaks, or windows that don’t last as long as they should.
With so many options out there, how do you know which window installer is right for the job? Instead of relying solely on reviews or flashy advertisements, asking the right questions can help you make an informed decision. Here’s what you should be asking before signing any contract.

1. Are You Licensed and Insured?
This should be your first question. A professional window installer should have the necessary licenses to operate in your area. Licensing requirements vary by state and city, but a legitimate contractor will have no problem providing proof.
Insurance is just as important. A reputable installer should carry both liability insurance and workers’ compensation. Liability insurance covers any accidental damage to your home, while workers’ compensation protects you from being held responsible if an employee gets injured on your property. If an installer lacks these, it’s a major red flag.
2. What Areas Do You Serve?
Local installers often work within a specific region, so it’s worth confirming they cover your location. Some companies may charge extra fees if your home is outside their primary service area.
If you’re looking for a reliable team in your region, it’s worth checking JMI Windows service locations to see if they operate near you. Finding a local installer with a strong reputation in your area ensures faster service and better post-installation support.
3. How Much Experience Do You Have?
Experience matters. A company that has been installing windows for years is more likely to do the job right the first time. Ask how long they’ve been in business and whether they specialize in the type of windows you’re installing.
Also, find out if they do the work themselves or subcontract to other crews. If they use subcontractors, ask about their qualifications and experience as well. The last thing you want is an inexperienced team handling your project.
4. Can You Provide References or Past Work Examples?
Any reputable window installer should have a portfolio of past projects or references from satisfied customers. Ask for photos of completed installations or, even better, visit a job site where they’re working.
If they hesitate to provide references, consider it a warning sign. Quality installers take pride in their work and should have plenty of happy customers willing to vouch for them.
5. What’s Included in the Quote?
Pricing for window installation can vary significantly, so it’s essential to get a clear, detailed quote upfront. Ask for a breakdown of costs, including:
- Labor fees
- Material costs (including the type of windows being installed)
- Additional charges for disposal of old windows
- Any potential extra fees (such as for unexpected structural repairs)
A detailed quote ensures you’re not hit with surprise charges later. It also allows you to compare quotes from different installers more accurately.
6. What Brands and Types of Windows Do You Offer?
Not all windows are created equal. Some installers work with a single brand, while others offer multiple options. Ask about the types of windows they recommend and why.
Energy efficiency is a crucial factor, so inquire about windows with double or triple glazing, low-E coatings, and gas-filled insulation. The right windows can significantly reduce energy bills while improving comfort.
7. Do You Offer Warranties on Installation and Products?
A solid warranty provides peace of mind. There are usually two types to consider:
- Manufacturer’s Warranty – Covers defects in the windows themselves.
- Installer’s Warranty – Covers workmanship and labor.
A reputable installer will stand behind their work. Ask how long the installation warranty lasts and what it covers. If the answer is vague or they don’t offer one, that’s a major concern.
8. How Long Will the Installation Take?
While the actual installation time depends on the number of windows being replaced, an experienced installer should be able to give you a reliable timeline.
Ask about potential delays—bad weather, supply chain issues, or unexpected structural problems can sometimes slow things down. A professional team will communicate these risks and have a plan to minimize disruptions.
9. How Will You Protect My Home During Installation?
Window replacement can be messy, so it’s important to know how an installer plans to protect your home. Ask about their cleanup process and what measures they take to prevent damage.
Key things to check:
- Do they use drop cloths to protect floors and furniture?
- Will they remove and dispose of old windows?
- How do they seal the work area to keep dust from spreading?
A professional company will leave your home as clean as they found it—without debris or damage left behind.
10. Do You Offer Financing Options?
Windows are a significant investment, and not everyone can pay in full upfront. Many companies offer financing plans, allowing homeowners to spread payments over time.
If financing is something you need, ask about interest rates, payment plans, and any potential fees. Compare these options with those from your bank or credit union to find the best deal.
Choose Wisely for Long-Lasting Results
Hiring the right window installer is just as important as choosing high-quality windows. By asking these essential questions, you can avoid costly mistakes and ensure you’re working with a skilled, trustworthy professional.
