Floor Systems Repair
We fix sagging, uneven, or damaged floors by repairing joists and subfloors to restore strength, stability, and long-term durability.
01 · The Service
Floors repaired to the flatness the finish trades require.
A floor that sags, bounces, or shows visible unevenness is not just a comfort issue — it is a structural one. The joists beneath it are damaged, undersized, or failing. The subfloor is compromised. And every finish floor material installed over a bad floor system — hardwood, tile, engineered flooring — will telegraph the problem back through the surface. Tile cracks. Hardwood squeaks and gaps. Floating floors show waves. The finish is only as good as what’s underneath it.
We repair floor systems by addressing the structural cause, not the surface symptom. Before any repair begins, we assess the existing floor system — joist span, joist depth, existing damage, subfloor condition, and any signs of moisture or rot that may have contributed to the failure. The repair scope is based on what we find, not on a fixed assumption of what the problem is.
Our floor repair work covers sistered joist repairs for damaged or undersized members, full joist replacement where the damage is too extensive to sister, subfloor replacement and levelling, beam and post repairs where the primary structural support has failed, and floor flatness correction where the existing system is structurally sound but uneven.
When we finish, the floor is flat to the tolerance the finish floor installer requires, the structure beneath it is sound, and the bounce and sag that triggered the repair are gone.

02 · Scope of Work
What's included.
Drawing Review
Structural assessment of the existing floor system before any repair begins — joist span, depth, damage extent, subfloor condition, and moisture or rot evaluated and documented.
Foundation Framing
Joist sistering for damaged, cracked, or undersized floor joists — new members installed alongside existing joists and fastened to restore full structural capacity.
Floor Systems
Full joist replacement where damage is too extensive to sister — existing failed members removed and replaced with new joists sized to current span and load requirements.
Wall Framing
Beam and post assessment and repair where primary structural support beneath the floor system has settled, rotted, or failed.
Roof Structure
Subfloor replacement where existing sheathing is damaged, delaminated, water-compromised, or too uneven to provide a suitable finish floor substrate.
Structural Steel Integration
Floor flatness correction and levelling where the existing structure is sound but the floor surface is uneven — shimming, planing, or self-levelling substrate as required.
Sheathing
Blocking and bridging installation to reduce floor bounce and improve lateral stiffness in floor systems that are structurally adequate but insufficiently braced.
Inspection Hand-off
Structural and building permit inspections coordinated where required. We stay on site until all sign-offs are complete.
Site Clean-up
All demolished framing, subfloor material, and site waste removed before we leave. Clean site handed off ready for finish flooring installation.
03 · How It Works
Our process.
01
Floor System Assessment
We assess the existing floor system before we quote. Joist condition, span, subfloor integrity, and any signs of moisture or rot are all evaluated and documented. The repair scope is based on what we find — so the work addresses the structural cause, not just the visible symptom.
02
Estimate & Repair Plan
You receive a clear scope and price based on the assessment findings. We sequence the repair work to minimize disruption and coordinate with your finish flooring installer so the repaired floor is handed off at the flatness tolerance their installation requires.
03
Structural Floor Repair
We execute the repair in the correct structural sequence — primary structure first, then joists, then subfloor and levelling. Every repair is made to the structural standard the floor system requires, not to the minimum needed to pass a visual check.
04
Inspection & Hand-off
We coordinate any required structural or building permit inspections and remain on site until sign-off is complete. The repaired floor is handed off flat, structurally sound, and ready for your finish flooring installer to begin.
