What do you love most about your job?
There's something satisfying about driving past a house we worked on years later and seeing the siding still looking sharp. We get to take a home that looks tired or dated and completely transform how it looks and feels, and every project is a little different, which keeps the work interesting after all these years.
What inspired you to start your own business?
I came to Canada from Croatia over 35 years ago looking to build a better life for my family. I had a young, growing family to provide for, and I wanted steady, honest work that could put food on the table and give my kids opportunities I didn't always have. I started small, doing the work right and taking care of my customers, and word got around. Over time it grew into A-1 Siding & Windows. Now my kids have grown up in the business and work alongside me, which means more to me than anything else we've built. I wanted to leave something behind that my family could be proud of and carry forward.
Why should our clients choose you?
We're a genuinely family-owned and operated company. When you call, you're talking directly to the people who own the business, not a call centre or a rotating cast of subcontractors. We've been doing this across the Niagara Region and Hamilton area for over 30 years, we give honest written quotes with no hidden costs, and we stand behind every installation we complete.
Can you provide your services online or remotely? If so, please add details.
No. Our work is hands-on exterior installation (siding, windows, doors, soffit, eavestrough), so it has to be done in person at your home. We also prefer to see every job in person before quoting, since it's the only way to give you an accurate price and make sure we recommend the right materials and approach for your specific home. That's how we make sure you get the best quality and the most honest number the first time.
