Your home worksas one system.So do we.
Third-generation skill, engineering-led diagnostics, and one accountable team for the plumbing, comfort, power, air, and water systems your property depends on.
Every essential system
One number to call. Five disciplines working together.
Most contractors see one trade. Sandison sees the interactions between water, air, power, fuel, controls, drainage, and the building itself.

Now exploring Heating, cooling, and controls
Comfort system01 / 08
Heating, cooling, and controls
- What it does
- Creates and moves conditioned air or heated water while thermostats and controls coordinate equipment operation.
- Warning signs
- Uneven rooms, short cycling, unusual noise, weak airflow, rising energy use, or equipment that cannot hold temperature.
- What shapes the decision
- Load, airflow or hydronic flow, combustion or refrigeration, venting, controls, and electrical demand should be tested together.
Air distribution02 / 08
Ductwork and indoor air quality
- What it does
- Distributes heated and cooled air while filtration, humidity control, and ventilation affect comfort and indoor conditions.
- Warning signs
- Hot and cold rooms, excessive dust, dry winter air, odors, noisy registers, restricted airflow, or condensation.
- What shapes the decision
- Equipment changes work best after duct capacity, static pressure, filtration, humidity, and room-by-room delivery are considered.
Water heating03 / 08
Tank and tankless water heating
- What it does
- Supplies dependable hot water through a storage tank or an on-demand heat exchanger sized for the property's peak use.
- Warning signs
- Temperature swings, delayed hot water, discoloration, leakage, ignition errors, scale buildup, or reduced usable capacity.
- What shapes the decision
- Capacity, gas supply, venting, power, water quality, drainage, service access, and maintenance shape the right system.
Water in and out04 / 08
Water supply, fixtures, and drains
- What it does
- Carries clean water to fixtures and equipment, then moves wastewater out through properly installed and vented piping.
- Warning signs
- Pressure changes, stains, active leaks, slow drains, recurring clogs, fixture movement, water hammer, or unexplained moisture.
- What shapes the decision
- Pressure, flow, drainage, venting, fixture condition, and concealed piping should be traced before access or repair is planned.
Drainage protection05 / 08
Sewer, sump, and basement protection
- What it does
- Moves sanitary waste away from the building and manages groundwater before it reaches finished spaces or critical equipment.
- Warning signs
- Slow drains, basement odor, gurgling, sewage backup, frequent pump cycling, high basin water, or discharge-line freezing.
- What shapes the decision
- Camera evidence, pipe condition, basin demand, pump capacity, backup power, check valves, and discharge routing define the response.
Power distribution06 / 08
Panel, circuits, and whole-home power
- What it does
- Receives utility power and distributes it through protected circuits to lighting, appliances, HVAC, pumps, and controls.
- Warning signs
- Frequent trips, flickering, overheated devices, buzzing, partial outages, damaged conductors, or insufficient panel capacity.
- What shapes the decision
- Circuit tracing, voltage testing, load calculation, grounding, bonding, panel condition, and future loads determine a safe scope.
Future-ready power07 / 08
EV charging and high-demand loads
- What it does
- Adds a dedicated charging circuit while accounting for service capacity and the home's other major electrical loads.
- Warning signs
- Limited charging speed, nuisance trips, warm connections, a full panel, undersized service, or competing equipment demand.
- What shapes the decision
- Demand, service and panel capacity, grounding, conductor route, charger location, and equipment requirements must be evaluated first.
Indoor safety08 / 08
Radon testing and mitigation
- What it does
- Creates controlled suction beneath foundation zones and discharges radon gas above the roofline when mitigation is needed.
- Warning signs
- Radon has no reliable smell or visual warning. Test results and post-mitigation verification provide the useful evidence.
- What shapes the decision
- Foundation zones, suction points, fan placement, pipe routing, discharge clearances, electrical power, and post-testing work together.
