The Heart Behind the Craft

With over 20 years in the construction industry, owner and founder, Jon Waszaj, brings a deep passion for craftsmanship and a commitment to doing things the right way. He began his journey hands-on, working in the field and learning every aspect of the trade from the ground up. Driven by a vision to provide homeowners with quality they can see and service they can trust, Jon built his business from scratch—one project, one relationship, and one satisfied client at a time.

Today, he leads Firmus Cabinetry with the same values he started with: integrity, attention to detail, and pride in every project. Whether it’s a kitchen, bathroom or office remodel or a full cabinetry design, Jon’s experience and personal touch are behind every step of the process.

When he’s not working with clients or perfecting a design, you’ll find him enjoying life in Southern Maine with his wife and three young kids and taking inspiration from the homes and natural beauty that surround the community he serves.
