Nampa, Canyon County
Shower Waterproofing in Nampa, Idaho
The membrane, pan and detailing work that decides whether a shower lasts five years or thirty.
Short answer
Nampa's older housing produces the classic failure we see most often: a stain on a ceiling or a soft floor outside the bathroom, traced to a mortar-bed pan sitting on a liner that gave up years ago. Those showers get rebuilt, not patched.

What shower waterproofing includes in Nampa
- Tear-out to framing so the assembly can be seen and documented
- Moisture readings before rebuild, and drying time if the framing is wet
- Replacement of damaged subfloor, plates and studs
- Bonding-flange drain matched to the membrane system
- Continuous membrane across pan, curb, corners, seams and walls
- Flood test before tile — the only stage where a pan can be proven
What we find in Nampa homes
- Mortar beds over failed pan liners are common in Nampa's 1950s-1970s bathrooms, often with the liner cut short at the curb.
- Because damage in older homes tends to run for a long time before anyone notices, the repair footprint frequently extends beyond the shower itself.
- We take moisture readings before rebuilding and hold the schedule until the framing is back in range rather than sealing moisture into a new assembly.
What moves the price
Waterproofing work is priced by what the demolition exposes. A pan rebuild with sound framing is predictable; wet plates, a rotted subfloor or a drain that has to be replaced are the variables.
- How far the water travelled — subfloor, plates and adjacent flooring
- Drying time before the rebuild can start
- Drain replacement to match a bonded membrane system
Systems and materials we use
- Bonded sheet membrane systems with banded seams and corners
- Liquid-applied membranes with reinforcing fabric
- Waterproof foam board wall and curb systems
- Bonding-flange drains, never a clamping-ring assembly under a bonded system

Permits in Nampa
City of Nampa Building Safety Department
Permit and inspection requirements for shower work are set by the local building authority and change over time. Plumbing changes, drain relocation and electrical work commonly require a permit; a like-for-like surface replacement often does not. We confirm current requirements with the jurisdiction before scheduling, and we pull the permits our scope requires. For Nampa addresses, that is the City of Nampa Building Safety Department.

Shower Waterproofing in Nampa — questions
- How do I know if my Nampa shower is leaking?
- Recurring stains on a ceiling below, a soft or discoloured floor just outside the shower, a musty smell, or grout that keeps cracking in the same place. Any of those is worth looking at before it reaches framing.
- Will you flood test the new pan?
- Always, before tile. It is the only stage where the pan can be proven watertight rather than assumed to be.
