Most bathroom renovations start leaking within 2 years. Ours don't — professionally waterproofed and backed by a 10-year leak and mold guarantee in writing.
If you've had a bad contractor experience — or you're terrified of having one — you're not alone. These are the four things GTA homeowners worry about most.
No waterproofing membrane. Just tile directly on drywall. The grout cracks, water seeps behind the tile, and mold grows inside your walls. By the time you smell it, the contractor is long gone.
Poor tile work is obvious the moment you step in. Uneven grout lines, tiles that aren't level, patterns that don't flow — it looks cheap no matter how much you paid for the materials.
Your bathroom is gutted, the crew hasn't shown up in four days, and construction dust is settling on every surface in your home. No updates. No timeline. Just chaos and a half-demo'd room.
Change orders stacked on top of change orders. Extras for things that should have been included. A verbal quote that meant nothing when the invoice arrived. No protection. No recourse.
We don't just build beautiful bathrooms. We build bathrooms that last — because every build gets a professional liquid waterproofing membrane on wet areas plus a Schluter base in the shower, and we back that with a written 10-year leak and mold guarantee. For maximum protection, the full Schluter KERDI system is available as a recommended upgrade.
Our standard package includes a professional liquid waterproofing membrane on all wet areas plus a Schluter base in the shower — a complete waterproofing setup that earns our 10-year leak and mold guarantee in writing. For clients who want the highest level of protection, we offer the full Schluter KERDI system as a recommended upgrade — the same setup used in commercial hotels and high-end builds. Either way, every bathroom we hand over is fully waterproofed and backed on paper.
Fixed quote. Fixed timeline. If we go over budget or miss the deadline — we pay you $1,500. No excuses. It's in the contract.
Before we quote, we do a detailed site visit, take precise measurements, and build a floor plan — so there are zero surprises during construction.
No subcontractors. Our own trained team handles every phase of your bathroom renovation — tighter quality control, better communication, cleaner results.
