    Hello! My name is Sebastian Trzcinski, owner of STC CONSTRUCTION. I’m a dedicated renovation professional with 5 years of hands-on experience working under my father, where I learned the trade from the ground up and built a strong foundation in quality craftsmanship. My experience includes framing, drywall, painting, trim installation, fixture work, and complete bathroom and kitchen renovations. I take pride in building projects properly from the structure out — ensuring framing is solid, finishes are clean, and every detail is completed with care. Growing up in the trade taught me not just technical skill, but patience, precision, and the importance of doing things right the first time. I understand how homes are built, allowing me to approach every project with proper planning, durability, and long-term value in mind. Whether it’s a full renovation or a smaller upgrade, I prioritize clear communication, reliability, and a clean, organized job site. I treat every home with respect and every project like it’s my own. My goal is to deliver results that look great today and stand strong for years to come.
