Serving Commack
Commack has deep 1960s–1980s subdivision inventory — four-bedroom colonials, hi-ranches, and splits on half-acre lots. Bathrooms are usually two-per-house (hall + master) and usually the original build-out with one refresh somewhere in the 90s. Plenty of good bones; plenty of hidden plumbing we should replace.
We do a lot of shower rebuilds and tile replacements in Commack — the 1990s fiberglass surrounds are failing, the cultured-marble vanity tops look dated, and the plumbing in the walls is well past warranty. We rebuild properly with Schluter, PEX supply, PVC drain, modern fixtures.
Suffolk County permits are routine. Commack hi-ranches sometimes need structural inspection if we reroute plumbing through the lower-level ceiling — we coordinate with the engineer if it's required.

What we've learned in Commack
Commack hi-ranches are ideal for plumbing work — second-floor bathroom drains run through an accessible first-floor ceiling. We can reroute drains, relocate toilets and tubs, and fix sins-of-the-past without major ceiling demo.
The fiberglass tub surrounds from the 90s are almost all failing — discolored, caulk-hopeful, cracked at pan-to-wall joint. Don't replace one with another. Rebuild properly with Schluter and tile.
Commack schools run tight morning and afternoon windows. We align our loud-work start times and dumpster deliveries to avoid bus traffic.
Almost every 1980s–1990s Commack vanity has a cultured-marble top with integrated sink that's yellowing and chip-scarred. Modern quartz + undermount sink upgrade costs less than people think. We quote it in every refresh.
