Water and Flood Damage Reconstruction for Homes, Strata, and Commercial Spaces
The dry-out crew stops when the moisture readings do. GP Contracting is the licensed BC general contractor that rebuilds what the water actually damaged: structure, subfloors, envelope, systems, and finishes, across the Lower Mainland, the Fraser Valley, and Vancouver Island.
Burst and frozen pipes
Pressurized supply lines can flood a floor in minutes and push water into cavities you cannot see. These losses usually mean framing replacement, subfloor work, and rebuilding finishes across more rooms than the burst itself touched.
Roof leaks and storm damage
Coastal BC rain and wind drive water through roofing, flashings, skylights, and window assemblies. The rebuild is as much building envelope work as interior work, and we treat the entry point, not just the stain on the ceiling.
Appliance and fixture failures
Dishwashers, water heaters, washing machine hoses, and toilet supply lines. Small sources, big spread: water follows gravity into the levels below, and multi-floor scopes are the norm rather than the exception.
Sewer backup
Category three water contaminates everything porous it touches. After specialist decontamination, we handle the strip-out verification and full reconstruction of the affected levels.
Strata and multi-unit losses
One failed pipe, four affected units, two insurance policies, and a strata council in the middle. We rebuild the units and the common property while keeping each scope attached to the right policy.
Rebuild Scope
What the Reconstruction Actually Covers
Structure and framing
Rotted studs, plates, joists, and headers replaced with new material and engineered connections where loads demand it, verified by inspection before anything closes up.

Subfloors and levelling
Heaved or delaminated sheathing replaced, substrates levelled properly, so the new flooring performs instead of telegraphing the old damage.

Envelope and moisture protection
Weather barrier, flashing, insulation, and vapour control repaired or upgraded so the assembly sheds water the way it should have in the first place.

Systems and finishes
Electrical, plumbing, and HVAC assessed and brought to current code, then drywall, paint, flooring, millwork, and fixtures rebuilt to pre-loss quality or better.

Still Drying Out? This Is the Moment to Plan the Rebuild.
The scope conversations that happen while the fans are still running decide what your claim will pay for. A free scope review with GP, before demolition finishes, means the hidden damage gets counted while it is still visible and the rebuild starts the day the site is ready instead of weeks after.
