Gresham’s Trusted Bathroom Renovation Contractor — Waterproofed Right, Tiled to Last
Most Gresham bathroom tile failures are not a tile problem — they are a waterproofing failure. The grout that is your shower's only moisture barrier eventually becomes permeable.
Water passes through, reaches the framing behind the tile, and creates the same hidden structural damage that VResh repairs behind improperly installed siding — only inside your home. VResh installs a continuous waterproof membrane (Schluter Kerdi or RedGard) over the full shower area before any tile is set. Grout is the finish surface. The membrane is the moisture barrier.

Why Gresham Bathrooms Need Renovation Now
Gresham's position in the eastern Portland metro — with year-round ambient moisture from Johnson Creek and Columbia Gorge wind-driven rain — means that any waterproofing failure in a home's interior wet areas becomes structural damage faster than in drier climates. Gresham's 1970s and 1980s bathrooms are now 40–50 years old. The original tile showers in these homes were installed with the waterproofing approach standard at the time — grout as the primary moisture barrier, tile directly over drywall or thin cement board, no continuous membrane behind the installation. That approach fails over time, and most of these original showers have been failing for years before the visible symptoms appear.
The 1970s Gresham Bathroom Shower Problem
Original tile showers from the 1970s and early 1980s relied on grout as the sole moisture barrier. Grout is water-resistant when first installed and new. It is not permanently waterproof — it becomes permeable over time, particularly as hairline cracks form at the floor-to-wall transition and at niche corners.
Once moisture passes through the grout, it reaches the substrate. Original cement board (or worse, standard drywall, which was common before 1985) behind the tile becomes saturated. The framing absorbs moisture. By the time tiles become loose or grout begins cracking visibly, the damage behind the wall is often significant.
What the Demo Phase Reveals on Gresham Bathroom Projects
When VResh removes original 1970s–80s tile from a Gresham shower, the discoveries are consistent: saturated and crumbling cement board, mold on the framing side of the substrate, and occasionally soft framing members behind the shower wall.
This is not a reflection of the homeowner's maintenance — it is the predictable outcome of a waterproofing system that relies on grout alone. VResh documents all findings before proceeding and provides a written scope for any structural or mold remediation work required.
Aging-in-Place — Accessible Bath Upgrades for Gresham's Original Homeowners
Many of Gresham's 1970s homes are still occupied by their original owners, who are now in their 70s and 80s. Accessible bathroom modifications — roll-in showers with curbless entries, reinforced blocking for grab bars, comfort-height toilets, and widened doorways — can extend the years a homeowner comfortably lives in their home.
VResh designs and installs accessible bath upgrades as part of full renovations or as targeted projects.
What VResh Actually Does on a Gresham Bathroom Renovation
A bathroom renovation done correctly starts with waterproofing — not with tile. Here is what VResh installs on every Gresham bathroom project.
Pre-Demo Walkthrough and Scope Agreement
Walk through the existing bathroom with the homeowner. Define what stays and what changes. Then demolition: remove existing tile, fixtures, and finishes. The demo phase is when the full condition of the substrate becomes visible.
What VResh Finds During Gresham Bathroom Demo
- Saturated cement board or drywall behind original 1970s–80s tile — standard finding on Gresham shower tear-outs. Once moisture has been reaching the substrate for years, it must be fully removed before new installation.
- Mold on the framing side of the substrate — mold behind tile does not respond to paint-over primer. It requires proper remediation protocol before new materials are installed.
- Soft framing members behind the shower wall — where sustained moisture reached the structural framing. Requires sistering or replacement before new substrate installation.
- Original plumbing valves without pressure balance — single-handle valves that do not balance pressure between hot and cold are not code-compliant for new installations. If the shower valve is being changed, a pressure-balanced valve is required.
Substrate and Waterproofing
Install cement board or Schluter Kerdi-Board over all framing in wet areas. Tape and waterproof all seams and transitions. Apply continuous waterproof membrane — Schluter Kerdi system, RedGard, or equivalent — over the full shower and tub surround. The membrane runs from the drain up the walls and over all transitions.
Why Grout Alone Is Not a Waterproofing System — What Most Gresham Tile Installations Skip
- Grout is a porous material when first installed and becomes more permeable over time as hairline cracks form at movement-prone locations: the floor-to-wall transition, niche corners, and curb edges.
- The waterproofing layer must be behind the tile, not at the tile surface. Applying sealant to grout improves surface resistance but does not create a continuous membrane.
- VResh does not install tile over standard drywall in wet areas — even in areas that are not directly wetted. Cement board or waterproof board is the correct substrate without exception.
Tile Setting, Grouting, and Sealing
Set tile using appropriate thinset for the substrate and tile type. Large-format tile requires back-buttering and a fully supported mortar bed — floating coverage is insufficient and causes hollow spots that crack.
Grout after full thinset cure. Apply penetrating sealer to all grout and natural stone tile. Caulk all movement joints — floor-to-wall transitions, niche edges, and curb edges — with flexible silicone caulk rather than grout.
Movement joints are where grout cracks first; flexible caulk accommodates thermal movement that grout cannot.
Vanity, Fixtures, and Finishes
Install vanity cabinet, countertop, toilet, shower door or enclosure, mirror, and all accessories. Connect all plumbing. Install exhaust fan if upgrading.
Drywall and paint all non-tile surfaces. Final inspection: test all plumbing for leaks, confirm all fixtures operate correctly, walk through with the homeowner. Written workmanship warranty issued at project completion.
