Write down the condition
Location, how long it’s been going on, any relationship to weather, and whether it’s changed over time all matter. A couple of photos and rough measurements make the first call more useful.
Read the local context
The city's Old West Side, platted starting in 1845 and listed on the National Register in 1972, still carries two-story frame houses built for a fast-growing 19th-century college town -- about 85% clapboard-clad, the rest brick or stucco -- later filled in with Dutch Colonials, bungalows, and Tudor cottages on small lots. Underneath that older core and the newer subdivisions built across Washtenaw County sits a mix of sand, gravel, and clay-rich glacial till left by retreating ice roughly 14,000 years ago -- fertile ground that also drains poorly, one reason bathroom waterproofing and remodeling work stays in steady demand across the area.
Ask what won’t be visible later
What actually holds up over time happens behind the tile — drain placement, framing, waterproofing transitions, ventilation, wiring capacity, and access all drive the real scope. The written scope should spell out exactly what gets checked and prepared before it disappears behind the finish.
Line up full scopes, not just prices
Protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranty terms, and change-order rules all belong in the comparison.
What official local sources add
The overlay district and the Community Rating System rating have almost no bearing on an interior bathroom, and it would be padding to claim otherwise. What genuinely shapes the work is the age of the housing underneath: Ann Arbor's older neighborhoods were plumbed in the galvanized-steel era, so relocating a fixture reliably uncovers supply that is at the end of its service life whatever the tile above it looks like. Budget for finding that rather than being surprised by it.
