Kitchens and bathrooms are where water does its quietest damage, and a water damage home inspection is often where buyers in Mississauga, Markham and Pickering learn the most about a house. A fresh vanity or new backsplash can look great while an old slow leak sits underneath. Below are the seven red flags I look for in every kitchen and bathroom, what they usually mean, and what to do next. Your inspector is Yama Nehan, a Certified and Registered Home Inspector with about 15 years of home inspection experience and a construction engineering degree from George Brown (Building Renovations). He is also a licensed contractor with about 20 years of construction experience and the owner of Nehan Construction, and that practical construction experience is one of the main reasons clients pick him. Yama Nehan is the only one trusted to do the inspections himself. Home inspections start from $499 and condo inspections from $399; the final price depends on the property.

Key takeaways
- Most kitchen and bathroom water damage starts small: failed caulking, loose toilets, slow drain leaks and tired shower grout.
- The ceiling below a bathroom often tells you more than the bathroom itself.
- Fresh paint on one patch of ceiling, a brand-new vanity in an older bathroom or a soft floor near the toilet are worth asking about.
- A home inspection is visual and non-invasive. I report what is visible and accessible and use a moisture meter on accessible surfaces; I do not open walls or remove tile.
- Inspection-first: Golden Home Inspections reports on condition and does not use the inspection to sell repairs.
Why kitchens and bathrooms matter in Mississauga, Markham and Pickering
These three cities have a lot of 1970s to 1990s two-storeys and townhouses, plus plenty of condos and newer subdivisions. In older homes, original bathrooms and kitchens have often been updated more than once, and each update can hide what came before. In newer homes and condos, the common issues are workmanship: missing caulking, poorly sloped shower bases and supply lines that were never tightened properly. For city-specific details, see home inspection in Mississauga and home inspection in Markham, or our general home inspection service.
The 7 red flags
- Staining or fresh paint on the ceiling below a bathroom. A brown ring or a single freshly painted patch on the main-floor ceiling under an upstairs bathroom is one of the clearest signs of a past or ongoing leak from the tub, shower or toilet.
- A soft or moving floor around the toilet. If the floor flexes or the toilet rocks, the wax seal may have been leaking into the subfloor for a while. I check for movement, cracked tile and staining at the base.
- Cracked grout, gaps in caulking or loose tile in the shower. Water gets behind tile through small openings. Hollow-sounding or loose tiles near the tub or shower base can point to moisture behind them.
- Swollen cabinet bases under sinks. Particleboard that is swollen, delaminated or stained under the kitchen or bathroom sink usually means a drain or supply line has leaked. I look for active drips, corrosion on shut-off valves and makeshift drain fittings.
- Poor bathroom ventilation. No exhaust fan, a fan that barely moves air, or a fan that vents into the attic instead of outside can lead to peeling paint, mildew on the ceiling and condensation problems in the attic.
- Dishwasher and fridge water line trouble. Staining on the floor near the dishwasher, warped flooring by the fridge or a kinked plastic ice-maker line are common in kitchens of every age.
- Musty smell or a new renovation that hides the old one. A strong musty odour, or a freshly finished bathroom in an otherwise original house, is not a problem in itself, but it is a good reason to ask the seller what was found and fixed.
What each red flag usually means
| What I see | Common cause | How it shows up in the report |
|---|---|---|
| Stain or patch on ceiling below bathroom | Tub, shower or toilet leak above | Note it, take meter readings, recommend asking the seller and further evaluation if readings are elevated |
| Soft floor or rocking toilet | Failed wax seal, loose flange, subfloor damage | Flag as a repair item and recommend a licensed plumber |
| Cracked grout, failed caulking, loose tile | Water getting behind the surface | Note as maintenance or repair depending on extent |
| Swollen sink cabinet base | Past or active drain or supply leak | Check for active leaks, note corrosion or improper fittings |
| Weak or missing exhaust fan | Moisture building up in the room | Note ventilation concerns and any visible mildew |
| Floor damage near dishwasher or fridge | Appliance supply or drain line leak | Note damage and recommend checking the connection |
Buyer checklist for kitchens and bathrooms
- Look up at the ceiling below every bathroom, not just at the bathroom itself.
- Open the cabinets under every sink and look at the base and the shut-off valves.
- Run the shower and the exhaust fan for a few minutes at a showing, if allowed.
- Ask the seller about past leaks, plumbing repairs and when bathrooms were last renovated.
- In a condo, ask whether there have been leaks from or into the unit above or below. Our condo inspection covers the unit itself.
- Book the inspection early enough in your conditional period to follow up on anything that comes up.
A situation we often see
A situation we often see in Pickering and Markham two-storeys is a nicely updated upstairs bathroom with a newly painted ceiling patch directly below in the kitchen or family room. The bathroom looks perfect, but the patch is the clue. The moisture meter may read dry if the leak was fixed, which is good news, but the buyer should still ask what happened and who repaired it. The report states what was seen and measured, without guessing beyond the evidence.
Where construction experience helps
Because Yama Nehan is a licensed contractor with about 20 years of construction experience and the owner of Nehan Construction, he knows how bathrooms and kitchens are built and where shortcuts usually happen: shower bases, tile edges, drain connections and fan ducts. That helps him read the signs behind a finished surface. The inspection stays inspection-first: you get a clear report on condition, not a repair sales pitch.

If you notice a musty smell or visible growth and want more than a visual inspection, see our home hazard testing page and mention it when you book.
FAQ
Can a home inspector find hidden water damage?
A home inspector finds evidence of it: staining, soft spots, elevated moisture meter readings on accessible surfaces, corrosion and smells. A home inspection does not open walls or lift tile, so hidden damage with no visible signs can be missed. That limitation is stated in the report.
Is a stained ceiling under a bathroom a deal-breaker?
Not by itself. Many are from old, repaired leaks. What matters is whether it is still wet, what caused it and whether it was fixed properly, so ask the seller and follow the report’s recommendations.
How much does a home inspection cost in Mississauga, Markham and Pickering?
Home inspections start from $499 and condo inspections from $399. The final price depends on the property, including size, age and type.
Who does the inspection?
Yama Nehan is the only one trusted to do the inspections himself, and reports reach you within 24 hours.
