A window project can feel simple until you realize windows involve more than choosing a style and a price. We see homeowners worry about spending the money and still ending up with drafts, stuck sashes, or service headaches months later. Replacing windows works best when you treat it like any other major purchase and ask questions that reveal the product details, the installation quality, and the company standing behind both.
That is exactly how we guide homeowners at Thermal King. We walk through the questions you should ask, then we back up every answer with experience you can verify.
What Questions Should You Ask Before Replacing Windows
Why “I Don’t Know What I Don’t Know” Matters
Most people do not buy windows often, so it is normal to feel unsure about what to ask. To the average person, a window is a window, and it feels like a basic home item. In reality, windows involve design, structure, warranty coverage, components, and long-term performance.
When you start with the right questions, you protect yourself from information gaps that can lead to regret later. We prefer to lay it all out up front so you can make a confident decision.
What You Are Really Buying When You Buy A Window
You are not only buying a piece of glass and a frame. You are buying a system with parts that must work together. You also buy the company’s process and their willingness to stand behind the job.
Ask the installer to explain:
- the window design and how it operates
- the structure and key components
- the warranty and how service calls work
Key takeaway: You can buy a great product, but a poor installation can make it worthless.
How To Evaluate The Company And The Installer
How Long Has The Company Been In Business
One of the first questions we recommend is how long the company has operated. Every company starts somewhere, and being new does not automatically mean they do bad work. Still, time in business gives you a track record that indicates the company knows what it is doing and will likely be there if you need it later.
At Thermal King, we have been in business for almost 25 years, and homeowners can verify that history through independent sources.
How Experienced Is The Person Installing Your Windows
Next, ask about the installer’s experience. You want someone who has been installing for years and years and knows the work well. You do not want your project to become a training job.
At Thermal King, we use employee installers, and many have been with us for years. Several have worked with us for decades, which helps us deliver consistent results and predictable quality.
How To Ask About Product Performance And Problems
What Are The Pros And Cons Of This Product
Ask how long the company has used the product they are recommending. Then ask for both the positives and the negatives. We recommend asking a direct question like this: What do you usually see go wrong with this product?
That question matters because nothing is perfect. You want to know whether the most common issues tend to be minor or serious. You also want to hear how the company handles the problem when it shows up.
How Will You Handle Issues If They Happen
A company that answers honestly should also explain its response plan. At Thermal King, we tell people that a common issue can be shipping damage that is hard to spot during installation, like a hairline fracture in the glass. Months later, that damage can show up as seal failure or cracked glass.
When that happens, we warranty it through us, and it becomes a non-issue with no cost to you. Other companies may describe common issues like sagging or bowing that can lead to windows that will not open or shut after a few years. You should hear those possibilities before you commit.
Pro tip: Ask for the most common negative they see and how they fix it. A clear answer tells you a lot about honesty and service.

How To Verify Claims With Reviews And Track Record
What Reviews And Ratings Say About Real Service
Most companies will say that they are the best, and you should expect that. Your job is to verify it. We encourage homeowners to check Google reviews and other public feedback so they can see patterns in communication, workmanship, and follow-through.
What Memberships And Local Presence Can Indicate
Ask about community presence and professional connections. Concrete examples include membership signals like the Chamber of Commerce and the Better Business Bureau. These do not replace good work, but they can add another layer of accountability that you can confirm.
Do your research and do not rely on a sales pitch alone. We want homeowners to verify our reputation because that is how trust should work.
If you want straight answers, a high-end product, and a high-end installation backed by a company that stands behind the work, schedule a quote with Thermal King for your window replacement needs.
