The short answer

Start with the complete system and the evidence

Facility work has to account for uptime, occupants, access, documentation, connected equipment, and the cost of repeat failure. Sandison evaluates the system and explains priorities in operational terms.

What Sandison evaluates

A practical path from symptoms to the right scope

  • Commercial HVAC and rooftop equipment
  • Plumbing, drains, and backflow
  • Electrical diagnostics and equipment connections
  • Preventive maintenance and condition reporting

Food-service systems

Drainage, water quality, hot water, ice equipment, and HVAC affect one another

Restaurants and hospitality properties operate long hours with concentrated drainage, grease, hot-water, ventilation, refrigeration-adjacent, and occupant-comfort demands. A drain complaint may involve buildup, venting, a damaged section, a cross-connection concern, or maintenance that has not reached the full run. Water filtration and scale can affect ice and hot-water equipment, while rooftop HVAC failures immediately affect guests and staff. Sandison documents the connected conditions before separating immediate restoration from longer-term correction.

Controlled service windows

The work plan must account for sanitation, access, shutdowns, and reopening

Commercial cleaning, milling, piping changes, equipment replacement, and rooftop work may require after-hours access, security coordination, protected food areas, water or electrical shutdowns, crane planning, and confirmation that the affected system is ready to return to use. Sandison communicates what can be completed during the available window, what remains concealed or unverified, and which follow-up belongs to the building owner, equipment supplier, restoration contractor, or another specialty provider.
