Easy Maintenance - Stained or damaged tile? Pop it out, put a fresh one down. Done.
Heavy-Duty Wear - Designed for commercial traffic and outlasts standard residential carpet.
DIY-Friendly - Simple installation - roll on adhesive like paint and stick them in. No heavy rolls, kickers, or padding required. No contractors, headaches or surprise costs

From Dated to Designer: A Kitchen Transformation You Have to See to Believe!
Ready for a kitchen glow-up without the massive price tag? Check out this incredible transformation!

By opening up two walls and swapping out old, worn cabinetry for our premium custom line, this space went from cluttered and dated to sleek, modern, and functional. The deep wood tones, modern hardware, and smart storage solutions paired with timeless subway wall tile (also from our site) completely redefined the room.

The best part? You can achieve this same high-end, custom look for a fraction of the usual cost. At Second Source Supply, we believe premium quality should be accessible.

When lease-end turnover season hits or a unit needs a full refresh before the next tenant moves in, every day on the turn schedule costs money in vacant loss.
Our partner BYCO Inc. specializes in high-efficiency unit turnovers and interior surface refreshes for multi-family communities. Instead of coordinating multiple subs during a tight turn window, you get one dedicated point of contact for trash outs, drywall repairs, paint, tile touch-ups, and LVT or floor replacements.

BYCO's 73 years in business. 7,200+ completed projects has been built on reliability.

The FAST Multi-Family Advantage:
• Rapid Unit Assessments: On-site estimate and turn-schedule commitment within 48 hours.
• Surge Capacity: Extra horsepower to absorb high-volume end-of-month lease rolls without missing lease start dates.
• Turnkey & Resident-Ready: Clean, durable finish work that passes final move-in inspections on the first walk—keeping common areas clean and neighboring tenants happy.
Facing a tight turnover schedule or need backup on upcoming unit upgrades? Call 262-894-6995 to get a crew scheduled for a site walk this week.

A long-abandoned restaurant in downtown Mayville has been
transformed into real, affordable apartment living.

Rezoning, repurposing, and restoring became the driving theme
behind the revitalization of the former BackStreet Café.

The conversion brought new life to the space, incorporating showroom kitchens, vanities, and cabinetry into the five newly created apartments - blending sustainability, practicality, and renewed purpose into the heart of downtown Mayville.

More than a tag line or idea, this is proof of concept - the tangible reality that Second Source Supply made possible.
