Home Inspection

System For Home Inspection

Although architectural details, wall and floor coverings, modern conveniences and many other factors are important in the buying decision, the focus of this inspection is on the structural/mechanical/electrical condition of the property.

The house inspection is designed to give the real estate agent or prospective purchaser a system to detect some of the readily accessible major flaws or deficiencies in the significant components and systems of a home. It is not designed to, nor does it profess to facilitate detection of all flaws, problems or occurrences that might exist in any given home.

To maximize time efficiency and to ensure all of the major sections of the home are take into consideration, we have developed a systematized approach to the inspection. This is a simplified overview of systems that professional home inspectors use when they are inspecting a home.

To assist you in following the system, we have provided a checklist that will guide you through your own house inspection.

General Inspection

The first step in inspecting a home is to examine the big picture for the home. Notice the area the home is located in. Are there other homes of similar age and construction details relative to the home you are inspecting? A comparison will give you a general idea of the upkeep of the home. Have there been significant modifications to the exterior of the building and if so, how is the workmanship?

Exterior Inspection

Start at the exterior front of the house and work your way around the house (clockwise or counter-clockwise) at a distance which allows you to view a complete face comfortably. On each face (front, sides, rear) start your visual inspection at the top of the structure and work your way down to the ground and lot area. As an example, you would start at the front and note the roof and chimneys, the gutters, fascia and soffits.

Then, moving down the exterior wall coverings (brick, wood, aluminum), noting windows, doors, etc. Examine any porches or decks down to the foundation, then the grade or slope of the lot area, followed by any coverings, such as flower beds, walkways, interlocking brick, driveways, etc.

Move nearer the house, to examine more closely any details which may have attracted your attention, without skipping any items. Having completed the front, move to the side of the house and start the same procedure (roof to ground)

Interior Inspection

On the interior, begin your house inspection in the basement and then follow the system throughout each floor in the house. The system for inspecting the interior is to begin with the floor, go to the walls and then the ceiling, and then consider any appliances or other items in the room. Move from room to room, always in the same direction (clockwise or counter-clockwise) so as to not miss any areas. If you see a door, open it!

In the utility room in the basement, first notice the floor, the walls (possibly the foundation walls are visible here), then the ceiling (floor joists may be visible), then go to the furnace, hot water heater, electrical panel, plumbing system, etc. When inspecting the floors, walls and ceilings, scan the entire area that is visible, not just one section.

In a finished room you would notice the floors, walls (including windows) and ceiling. Next look for the heat sources, electrical outlets and switches, fireplaces, closets etc. In bathroom or kitchen, notice the floor, walls and ceiling, then the plumbing fixtures.

Home Condition Inspection

While performing the home inspection, whether at the exterior, the interior or one of the mechanical systems, note the system first, then its relative condition. For example, if you were inspecting a wall on the interior of the home you would first note that the wall is plaster, and then examine the wall for cracks and irregularities.


The following are some typical problems or occurrences to look for in the major components and systems of the home:

Problems With Roof
Is the ridge (peak) showing a sag, or is it straight and level?
Is the roof sagging between the rafters or trusses?
Are there any signs of deterioration of asphalt shingles, such as curling, wasping, broken edges, rounded corners or key holes (slits) becoming wider that normal?
Are there any loose flashings, at the chimney, roof-to-wall connection or elsewhere?
Does the wooden roof deck appear rotten or delaminated under the last row of shingles?
Are there any roof vents visible?

Problems With Chimneys
Is the masonry cap cracked or broken? Are any bricks flaking or missing? Is any mortar missing? Is the chimney leaning?

Problems With Soffits and Fascia
Note whether the soffit and fascia are wood, aluminum or plastic Any loose or missing sections?
If wood, are there any paint problems? Any visible rot?

Problems With Gutters and Downspouts
Ensure gutters slope down toward downspouts- is there any rust or peeling paint?
Are there apparent leaks or loose/sagging sections?
Are the downspouts extended away from the foundations?

Problems With Wall Coverings
Look for missing mortar
Are the bricks flaking or cracking?
Look for loose, missing or rotten siding, deteriorated paint.
Does the siding appear new? Does it hide the foundation wall?
Are the exterior walls bowed, bulged or leaning?

Problems With Windows And Doors
Look for problems with paint or caulking, and rotted wood components. Are the windows new or older? Are they the original windows?

Problems With Porches and Decks
Cracking or flaking masonry?
Check for paint problems, rotted wood, and wood-earth contact.
Note any settlement or separation from the house.
Inspect the underside, if accessible.

Problems With Foundations
Check for cracks, flaking or damaged masonry.
Note any water markings and effluorescence (whitish, chalky substance) Any bowing, buldging or other irregularities?
Soft mortar?

Problems With Lot Area
Does the grade slope away from the house?
Any settled/low areas next to the foundation, or cracked walks/driveway? Is the property lower than the street or neighboring properties?

Problems With Basement
Note any evidence of water penetration (stains, mildew/odors, effluorescence, loose tiles etc.)

Problems With Floors
Check for deteriorated coverings or cracked ceramics. Any water staining or other damage? Sloping or sagging?

Problems With Walls
Randomly sample to check that the windows and doors work. Are the walls straight vertically and horizontally? Look for cracked or loose plaster. Look for stains, physical damage or previous repair evidence. Any drywall seams or nails showing?

Problems With Ceilings
Check for cracks in the plaster or loose, sagging plaster. Look for stains, mechanical damage or evidence of previous repair. Seams or nails showing?

Problems With Bathrooms And Kitchens
Check that all fixtures are secure. Are there any cracks in the fixtures? Note the conditon of the tiles and caulking in the tub/shower area. Are the faucets working? Do they leak? Sufficient water pressure? Look for staining and rot under the counter-tops Randomly sample the operation of the cabinet doors and drawers.

Electro-Mechanical Considerations
Type, style and age of heating & cooling systems. When were they last inspected or serviced? Type of water supply piping and drains - any visible rust and corrosion? Size and age of electical service - are the outlets grounded? Visible wiring in good condtion? Have there been any upgrades?
