Services
Foundation Repair
Our foundation repair specialists address cracks, settling, and structural weakness using advanced underpinning techniques. We replace failing walls without raising homes, install frost-protected foundations, and reinforce compromised structures. With 90 years of experience, we ensure lasting solutions that prevent water intrusion and maintain building integrity.
Structural Moving
We safely relocate entire buildings using specialized steel dollies and transport systems. Our team has moved 6,000+ homes and structures since 1934, employing precise engineering to lift, transport, and set buildings on new foundations without damage.
Basement Waterproofing
Our comprehensive waterproofing solutions include drain tiling installation, wall crack repair, and vapor barrier systems. We address both surface water and groundwater issues through proper grading, backfilling, and sump pump installation to maintain dry, usable basement spaces.
House Leveling
We correct uneven floors and structural tilting using precision jacking systems. Our process involves assessing settlement patterns, stabilizing the structure, and re-leveling foundations to restore proper alignment and prevent further damage to walls and framing.
Drain Tiling
Our drain tiling installations protect foundations by redirecting groundwater away from structures. We use modern perforated piping systems buried beneath frost lines to create effective drainage networks that prevent basement flooding and foundation erosion.

Report
I have a home in Sayner,Wi.In 1969 a kitchen addition was added to the home built on log peers which were rotting away causing the building to lean.Lassig Brothers came in ripped out the old foundation and rebuilt a new cinderblock foundation, and leveled the entire structure. The work was done top-notch and it was done in a very timely fashion. Definitely would recommend this company to anyone needing foundation work done or a house or building moved.
