A good window installer is like a good barber—if they do it right, you’ll admire their work every time you pass by. But if they mess up? You’ll be reminded of it every single day.
Replacing your windows is a big investment, and choosing the right installer is just as crucial as selecting high-quality windows. A poorly installed window can lead to energy loss, leaks, and costly repairs down the road.
But with so many window contractors out there, how do you know which one to trust?
The key is to ask the right questions before hiring window installers (or even roofers) in Salt Lake City. Doing your homework upfront ensures you get the best service, value, and long-term performance from your new windows.
Before you make a decision you could regret every time the wind howls through a lousy seal, ask these 10 questions.
1. Are You Licensed and Insured?
The first and most important question to ask any window installer is whether they are licensed and insured. You wouldn’t let an unlicensed driver drive your car or an uninsured plumber flood your basement, so why risk it with your windows?
A legitimate contractor should have the proper licensing to perform window installations in your area. Insurance is just as crucial—both liability and workers’ compensation—so you won’t be held responsible for accidents or property damage during the project.
If a contractor hesitates to provide proof of either, that’s a major red flag. If something goes wrong, a handshake promise won’t cover the damages.
2. How Much Experience Do You Have?
Everyone has to start somewhere—but preferably not with your house. Installing windows requires skill, precision, and attention to detail, so experience matters because even a tiny mistake can lead to drafts, leaks, or a window that won’t open.
Ask the contractor how long they’ve been in business and how much experience they have, specifically with window installations. An experienced installer can handle challenges like unusual window shapes, older homes, and varying wall materials. If possible, look for a contractor with at least five years of experience in the industry.
3. Can You Provide References or Reviews?
Any reputable window installer should be able to provide references from past clients or direct you to online reviews. Don’t just take their word for it—check the reviews on Google, Yelp, or the Better Business Bureau.
If they provide references, ask past customers about their experience, the quality of the work, and whether the project was completed on time and within budget. If the window contractor does excellent work, happy customers should be more than willing to vouch for them.
4. What Types of Windows Do You Install?
Not all windows are created equal—just because a contractor can install one type doesn’t mean they can install all. Whether you’re interested in double-hung, casement, bay, or energy-efficient windows, make sure the installer has experience with the specific style and brand you want.
If you’re unsure which windows are best for your home, a knowledgeable contractor can walk you through the options and make recommendations based on your needs. The best installer won’t just push the brand or style they use; they’ll help you find the right fit for your home and budget.
5. Do You Offer a Warranty on Labor?
Even the highest-quality windows won’t perform well if installed incorrectly. And even the highest-rated contractors can have an off day.
That’s why it’s important to ask if they offer a warranty on their labor in addition to the manufacturer’s warranty on the windows. If something goes wrong, you’re covered—without extra costs.
A confident installer stands by their work with a solid labor warranty, typically one to five years. If they don’t offer an installation warranty, what does that say about their confidence in the job they’re doing?
6. What’s Included in the Quote?
As they say, the devil’s in the details, so while that super low quote might sound fantastic, get a detailed breakdown of what it includes before signing.
For example, does it include materials, labor, permits, and cleanup? Are there any additional fees that might pop up later?
A trustworthy contractor will provide transparent, itemized, free estimates for roofing, windows, or whatever service they provide, so you know exactly what you’re paying for. Be wary of quotes that seem too good to be true—sometimes, low prices come with hidden costs or cut corners.
7. How Long Will the Installation Take?
Timing is everything, especially if you’re replacing multiple windows. You don’t want to live with a half-finished project during the first big snowstorm of the year.
Ask the installer how long the project will take from start to finish. While the actual window installation can often be completed in a day, factors like custom window orders, weather conditions, and contractor schedules can affect the timeline.
A reliable installer will give you a realistic estimate with a clear start and finish date and keep you updated throughout the process.
8. Will You Remove and Dispose of My Old Windows?
“Out with the old, in with the new” should be a mantra for your window installer. Make sure your contractor includes removing and disposing of your old windows in their service. If not, you might be left with a pile of old frames and glass that you have to figure out how to dispose of yourself.
A professional installer is like a great camper—they leave no trace. They should take care of this as part of the job so you can enjoy your new windows without the mess.
9. How Will You Protect My Home During Installation?
Window installation can be messy, and the last thing you want is dust, debris, or damage to your walls and flooring. Ask your installer what precautions they take to protect your home during the project, such as laying down drop cloths and sealing off work areas.
You want your installer to treat your home like a surgeon in a clean room, carefully protecting every surface so they do not damage it while working their magic on your windows.
10. Do You Work With Other Home Exterior Contractors?
If you’re upgrading your windows, you might also consider other exterior home improvements, such as siding replacement. In that case, it’s worth asking if the installer works alongside other professionals, like a residential siding contractor, for a cohesive home upgrade.
Coordinating projects like siding and window replacement can improve your home’s insulation and curb appeal while saving you time and money in the long run. When your window installer has a few contractor friends in their back pocket, you’re less likely to get stuck with scheduling delays or mismatched work.
The Right Contractor
Hiring the right window installer can be the difference between a flawless upgrade and a frustrating project. By asking these ten questions, you’ll get a clear view of their experience, reliability, and professionalism. Take your time, compare quotes, and don’t hesitate to ask for references.
A trustworthy installer will appreciate that you’re an informed homeowner. With the right expert on the job, you’ll enjoy fresh, energy-efficient windows—and a hassle-free experience.
