Component by component
- Foundation90%
What is found and what to do
What inspectors note most often
- Cracks in the foundation walls
- Missing or damaged parging
- Efflorescence (white deposits) and exposed form ties
What you can do
Most cracks are harmless shrinkage cracks. Ones that widen, run in steps or let water in need a specialist’s opinion.
- Siding (Wood, Vinyl, Fiber Cement)80%
What is found and what to do
What inspectors note most often
- Cladding too close to the ground
- Cracked mortar and blocked weep holes (brick)
- Exposed base of the walls (sill plate, rim joist)
What you can do
During the visit, walk around the house and look at the bottom of the walls: that is where water and moisture do the most damage.
- Electrical Outlets & Receptacles75%
What is found and what to do
What inspectors note most often
- Outlets near water without GFCI protection
- Missing cover plates
- Exposed wires or open junction boxes
- Reversed polarity
What you can do
Usually small fixes, but they are about safety. Get a quote from a master electrician before you sign.
- Balconies, Decks & Terraces70%
What is found and what to do
What inspectors note most often
- Missing, low or unstable guardrail
- Unprotected posts and supports
- Wood needing upkeep, missing joist hangers
What you can do
First a safety issue, especially with children. A guardrail is a quick fix; a rotten balcony structure costs much more.
- Flashing & Solins70%
What is found and what to do
What inspectors note most often
- Dry, cracked or missing caulking
- Sealant to redo around windows and doors
- Poorly installed flashing
What you can do
Worn caulking is routine, inexpensive upkeep. Letting it go lets water into the walls.
- Gutters & Downspouts70%
What is found and what to do
What inspectors note most often
- Downspouts that drain too close to the foundation
- Gutters clogged with debris
- Missing or damaged gutters
What you can do
A small job with a big stake: roof water dropped at the foot of the wall often ends up in the basement. Downspout extensions cost little.
- Bathroom Plumbing & Fixtures65%
What is found and what to do
What inspectors note most often
- Loose or rocking toilet
- Worn shower or tub seals
- Loose or leaking fixtures
What you can do
Look at the base of the shower and around the toilet: a worn seal lets water into the floor long before it shows.
- Exterior Windows65%
What is found and what to do
What inspectors note most often
- Not enough clearance under the windows
- Fogged sealed units (failed seal)
- Windows at end of life, worn weatherstripping
What you can do
Ask how old the windows are. A fogged sealed unit can be replaced on its own, without changing the whole window.
- Interior Walls60%
What is found and what to do
What inspectors note most often
- Water stains on walls
- Cracks in drywall
- Cosmetic damage
What you can do
A crack or a mark is often cosmetic, but a water stain has a cause: ask where it came from and whether it was fixed.
- Bathroom Ventilation60%
What is found and what to do
What inspectors note most often
- Missing, weak or faulty fan
- Fan not vented outside
- Duct emptying into the attic
What you can do
Without good ventilation, shower moisture ends up as mould. Turn the fan on during the visit.
- Attic Insulation55%
What is found and what to do
What inspectors note most often
- Insufficient insulation
- Uninsulated ventilation ducts
- Poorly insulated or sealed attic hatch
What you can do
Too little insulation shows on the heating bill and can cause ice dams. Adding attic insulation is one of the most cost-effective upgrades.
- Main Electrical Panel55%
What is found and what to do
What inspectors note most often
- Grounding not found or not visible
- Missing panel door or cover plate
- Poorly anchored service mast
What you can do
Ask for the age and make of the panel: some older models are refused by insurers. An electrician can confirm the grounding.
- Water Heater55%
What is found and what to do
What inspectors note most often
- Water heater 10 years or older
- No drain pan
- Missing discharge pipe
What you can do
Check the date on the label. After 10 years, many insurers ask for a replacement, and a leaking tank can flood the basement.
- Grading & Drainage55%
What is found and what to do
What inspectors note most often
- Ground sloping toward the house
- Downspouts to extend
- Foundation drain not checked or doubtful
What you can do
The ground should carry water away from the house. If the foundation drain is old, ask for a camera inspection: it is one of the most expensive jobs on a house.
- Roof Structure50%
What is found and what to do
What inspectors note most often
- Stains or water marks on the framing
- Condensation and signs of mould in the attic
- Damaged framing members
What you can do
Stains in the attic can be old or active. Ask whether a leak was repaired, and have the attic ventilation checked.
- Smoke Detectors50%
What is found and what to do
What inspectors note most often
- Missing carbon monoxide alarm
- Missing or outdated smoke alarms
- Not enough alarms for the house
What you can do
A smoke alarm should be replaced every 10 years. It is the cheapest fix on the list: do it when you move in.
- Interior Stairs & Railings45%
What is found and what to do
What inspectors note most often
- Missing, broken or unsuitable handrail
- Missing or incomplete guardrail
- Uneven step heights
What you can do
Simple fixes, but important to prevent falls.
- Interior Piping & Materials45%
What is found and what to do
What inspectors note most often
- Worn or missing seals
- No water hammer arrestors
- Leaks
What you can do
Look under the sinks during the visit. A small leak that lasts damages cabinets and floors.
- Pitched Roof Covering45%
What is found and what to do
What inspectors note most often
- Worn or damaged shingles
- Ponding water, poorly sealed seams
- Missing vent caps
What you can do
Ask how old the roof is. An asphalt shingle roof usually lasts 15 to 25 years: if it is near the end, plan for it in your budget.
- Interior Windows45%
What is found and what to do
What inspectors note most often
- Missing opening limiter (child safety)
- Faulty opening mechanism
- Stains or mould at the bottom of the windows
What you can do
Open and close a few windows during the visit. Stains at the bottom of the frame often point to condensation.
- Contamination (Asbestos, Mold, etc.)40%
What is found and what to do
What inspectors note most often
- Spots that look like mould
- Materials that may contain asbestos, depending on the year built
- Musty smell
- Old oil heating system
What you can do
Only a lab test confirms asbestos or mould. Before renovating a house built before 1990, have the materials tested.
- Insects & Pests40%
What is found and what to do
What inspectors note most often
- Ants
- Rodents
- Signs of pests in the attic or basement
What you can do
Carpenter ants in the wood or active rodents call for an exterminator before you move in.
- Exterior Faucets / Hose Bibs40%
What is found and what to do
What inspectors note most often
- Faucets not protected from freezing
- Missing vacuum breaker
- Faucet out of service
What you can do
Shut off outdoor faucets every fall, or install frost-free ones: a frozen pipe can burst inside the wall.
- Driveway & Parking40%
What is found and what to do
What inspectors note most often
- Ground sloping toward the house
- Plants or trees too close to the building
- Sunken or cracked walkways and driveway
What you can do
Trim plants touching the walls and make sure water drains away from the house.
- Attic Ventilation35%
What is found and what to do
What inspectors note most often
- Insufficient ventilation
- Blocked soffit intakes
- Gable vents disrupting the airflow
What you can do
A poorly ventilated attic traps moisture in winter: mould on the wood, ice dams and a roof that ages faster.
These are frequencies in similar homes, not a diagnosis of yours. Only an inspection can tell you what is really there. How I count.
