Sink Installation & Replacement in Southern Maine
Sink installation looks straightforward until you're wrestling with a stuck shutoff valve from 1987, a drain that doesn't align with the new basin, or a garbage disposal mounting collar that doesn't match the new sink's drain opening. AT Plumbing Services handles kitchen, bathroom, laundry, and utility sink installations across Southern Maine — correctly, cleanly, and without leaving you with slow drains, misaligned P-traps, or water damage accumulating quietly in the cabinet below.
We handle the full scope of any sink installation: shutoff valve condition assessment, supply line connection, drain and P-trap configuration, garbage disposal mounting and wiring coordination, and dishwasher drain hookup where applicable. We arrive with the parts needed to complete the job in a single visit — because coming back for a forgotten component doesn't work for anyone's schedule.
Whether you're swapping a dated kitchen sink as part of a full remodel or adding a utility sink to a garage or mudroom, we approach the job the same way: assess what's there, determine what needs to change, and install the new fixture so it works correctly and lasts.

Our Sink Installation Process in Southern Maine
Supply and drain assessment
We check shutoff valve condition, supply line age, drain line alignment, and P-trap clearance before the new sink goes in.
Configuration verification
We confirm the faucet hole count and spacing matches your chosen faucet before cutting or setting anything irreversible.
Secure mounting
Correct clips, brackets, or supports depending on sink type — properly sealed at the countertop edge to prevent water intrusion.
Drain and disposal connection
P-trap configuration, disposal mounting if applicable, and dishwasher drain connection — all in a single visit.
Full test before departure
Hot, cold, drain flow, and disposal operation all verified before we pack up.
Benefits of Professional Sink Installation in Southern Maine
Shutoff valve assessment every time
We check and replace aging shutoff valves as part of every sink job — the least expensive way to prevent a future flood.
One-visit installation
We arrive with the parts and tools to complete the job in a single trip.
Correct drain slope and P-trap configuration
