Serving Oakland and Macomb Counties Office hours: Monday–Friday, 8:30 a.m.–4:30 p.m.

The short answer

Rochester is a distinct service and permit location

Provide the full property address when you request service. Rochester, Rochester Hills, and Oakland Township are separate municipalities, even when a mailing address or nearby landmark sounds similar. Confirming the location helps the office prepare the service visit and identify the appropriate local authority for a proposed installation or alteration.

City permit resources

Outside water and sewer work has a separate application route

Rochester's Building Department applications page lists electrical, mechanical, and plumbing resources. It specifically directs outside plumbing work to the DPW application, which covers categories including water, sewer, and right-of-way work. This distinction matters when a sewer concern leads from an interior diagnosis to excavation or work near public infrastructure. Sandison identifies the proposed work, access, utility interfaces, and permit responsibilities before representing that one application covers the entire job. Current requirements are confirmed with the city for the actual project.

Concealed and connected systems

A leak or recurring backup needs a defined investigation before access

Before the visit, note which fixtures are affected, when the condition appears, whether more than one drain is involved, and any prior repair or camera inspection. Safe photographs and existing reports can help the technician plan the investigation. Interior symptoms do not by themselves prove a damaged exterior sewer, and an image of one exposed section does not establish the condition of the full line. We explain confirmed findings, limitations, options for further testing, and the scope of any opening or excavation before that work is authorized.

Comfort and power

Replacement decisions should account for the existing installation

A furnace that cannot keep up, an air conditioner that short-cycles, inconsistent hot water, or repeated breaker trips can involve more than the first component that appears to fail. The service request should identify the equipment, affected rooms, timing, recent changes, and any safely visible fault code. Sandison evaluates the relevant connections, explains repair and replacement options, and considers controls, airflow, venting, drainage, electrical capacity, and service access as appropriate. Scheduling and equipment availability are confirmed before a project commitment is made.
