A Residential Home Inspection is a visual inspection of the home normally initiated by the potential buyer in real estate transaction. However, a residential home inspection can also be initiated by the seller or sought by the current home owner. The inspection looks at the major components of the home and identifies potential defects and makes recommendations for further evaluation, follow-up. The major working systems/components of a home include the roof, attic, the electrical system, the plumbing system, HVAC system, basement/foundation, the interior and exterior, landscaping, and garage if present. Although normally identified as a non-scope item, a residential home inspection could also include ancillary features, like pools, retaining walls, and large out-buildings. 

The home inspection is normally two-to-four hours in duration and most inspectors provide a period after the inspection (or during) to walk-thru the home pin-pointing defects the inspector found, and allowing the real estate agent and client to ask questions. A home inspection report is normally provided same or next-day. The report details the findings of the inspection and makes recommendations for further follow-up.

The Roof

On the inspection, we will inspect the entire roofing system which includes the roof-covering materials; such as, asphalt or tile. The gutters, downspouts, and flashing are observed to ensure optimal water drainage from the roof surface and the roofing vents, flashing, skylights, chimney and other roofing penetrations are checked to ensure optimal air flow from the home interior.

Plumbing System

On the inspection, we will located and inspect the main shut-off valves, which includes both the water supply shut-off valve and the main fuel supply shut-off valve.  The heating equipment (water heater, boiler, etc) is also inspected as well as the associated components - venting connections, temperature/pressure-relief (TPR) valves, and any bracing that be supporting the heating equipment.  Just as we check for air flow with the HVAC - we will inspect the faucet fixtures for functionality and flow. Other plumbing features typically observed include toilet and kitchen waste disposal operations, tubs and showers, vent system, and sump pumps if present.

The report will provide more information on the components used in the plumbing system, make appropriate recommendations, and discuss any deficiencies observed with the plumbing functionality or its components.

Heating, Ventilation, and Air Conditioning (HVAC)

On the home inspection we will observe the heating and cooling system for the home, and operate the system to ensure functionality.  We will observe the air distribution and ventilation activities to ensure each room of the home is receiving conditioned air where appropriate -- This is important because ventilation helps  the breathing and reduces air moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and even other natural gases like radon.  We will check the condition of the mechanical components to ensure nothing is completely out of the ordinary, falling off, or presenting a potential safety hazard. 


 Your home inspection report will detail the operation control and provide information on the homes energy source (gas, electricity, hot water, etc) and heating method (furnace/HVAC, radiator, boiler, etc) for the system.  The report will also include the date of installation for the systems mechanical components, and make recommendations for servicing or replacement if warranted.

The home inspection will look at all areas of the electrical system where possible and visible, from the service drop/service head area, to the interior receptacles. We will inspect the electrical meter and base, service entrance conductors, the main service disconnect, panel boards, and grounding/bonding. We will test electrical outlets in appropriate area to ensure compatibility with code requirements; such as, Ground-Fault Circuit Interrupter (GFCI) receptacles and circuit breakers. We will also check the smoke and carbon monoxide detectors in the home to ensure their presence and functionality.
