Bathroom Inspection — Moisture, Ventilation, and Plumbing

Bathrooms are the highest moisture area in the home. Tile failures, exhaust deficiencies, and plumbing leaks are found in the majority of inspections.

Last Tuesday on Plains Road, I opened the cabinet under a beautifully renovated kitchen sink and immediately smelled something off — that musty, wet cardboard smell that makes my stomach drop. The pristine subway tile backsplash and quartz countertops had distracted everyone from what mattered most. When I aimed my flashlight into that dark corner, I found black mold creeping up the back wall and a slow drip that had been going unnoticed for months. The buyers were about to make the biggest mistake I see in these 1970s Burlington splits.

Here's what I've learned after fifteen years of crawling through Burlington kitchens: the pretty stuff sells houses, but the hidden stuff breaks budgets. You'll spend your first year in that dream home dealing with problems the staging couldn't hide.

I always start my kitchen inspection at the sink because water damage tells me everything about how a home's been maintained. In these Aldershot and Tyandaga neighborhoods, most kitchens got their last major update sometime in the 2000s. The cabinets look decent from the outside, but open those lower doors and you'll often find warped particleboard, failed caulking, or worse.

What I find most concerning is how buyers get swept up by granite countertops and stainless appliances while ignoring the stuff that actually costs money to fix. That beautiful kitchen island? It's not going anywhere if you discover the subflooring underneath is rotted out from a dishwasher leak. I quoted one family $12,300 just to repair water damage under their "move-in ready" kitchen last spring.

The electrical tells its own story in these older Burlington homes. I'll pop open that panel above the microwave and find aluminum wiring that should've been replaced decades ago. Sometimes there's knob and tube lurking behind those painted-over walls. You planning to add that coffee station or wine fridge? Good luck when you discover your kitchen's running on two circuits from 1974.

Check Your Home Risk

Buyers always underestimate plumbing issues until they're living with them. I was inspecting a Fairview home last month — gorgeous kitchen renovation, everything looked perfect. But when I turned on both taps and ran the dishwasher simultaneously, the water pressure dropped to nothing. Guess what we found? The main line hadn't been updated since the Carter administration. The repair estimate came back at $8,750.

Appliances are where I see the most buyer confusion. Just because something's stainless steel doesn't mean it works properly. I've got this little routine where I actually run the dishwasher, check every burner on the stove, and test both oven racks. Last week, a "high-end" range had a dead burner and an oven that ran 50 degrees hot. The sellers had been working around these problems for years, but nobody thought to mention it.

Then there's the stuff you can't see that'll drive you crazy later. Cabinet hardware that looks solid until you actually use it daily and those soft-close hinges start failing one by one. Drawer slides that bind up after six months of real use. I had one client spend $2,400 just replacing cabinet hardware that looked fine during the showing but fell apart by Christmas.

The ventilation situation in most of these 1960s and 1970s Burlington kitchens makes me shake my head. These homes were built when nobody thought about air quality or moisture control. I'll find range hoods that vent directly into the attic space instead of outside. Sound familiar? You'll cook one big family dinner and wonder why your smoke detector won't stop going off.

Flooring under kitchen islands is my favorite surprise. Sellers love to add islands during renovations, but they rarely extend the flooring underneath. Everything looks perfect until you want to reconfigure the layout someday. I've seen buyers discover three different floor types under one kitchen — original hardwood, linoleum from the 1980s, and whatever cheap laminate they threw down before selling.

What really gets me is the tile work in these updated kitchens. Looks amazing in photos, but run your hand along those grout lines and you'll feel where corners were cut. Poor tile installation leads to loose tiles, cracked grout, and eventually water getting behind your beautiful backsplash. The fix isn't cheap — I've seen estimates ranging from $4,200 to $11,500 depending on how far the damage spread.

Storage solutions always tell me about the homeowners too. Open those deep corner cabinets and you'll find either ingenious organization or a black hole where mixing bowls go to die. Pantry spaces in these older homes were afterthoughts, usually carved out of whatever space was left over. You'll think you have enough storage until you actually try to live there.

Counter space is another thing that photographs well but doesn't always work in real life. These galley-style kitchens in downtown Burlington look charming, but try prepping Thanksgiving dinner when your only workspace is a 24-inch strip next to the sink. I always pace through the cooking workflow during my inspections because you'll be doing it every single day.

In fifteen years, I've never seen a kitchen that didn't have at least one expensive surprise hiding somewhere. The key is finding those problems before you're holding the keys and writing repair checks. Get someone like me to look past the pretty surfaces and tell you what April 2026 is really going to look like in that kitchen.

Don't let Burlington's competitive market pressure you into skipping the details that matter. I've seen too many families learn expensive lessons they could've avoided with one thorough inspection.
