A reader wrote in after one of our slab pieces asking which contractor we’d used for the quote in the piece. We hadn’t used one. There was no quote, no job, no invoice sitting behind that article — just a defect that shows up often enough in reports to be worth explaining. The question comes up more than you’d think, and it’s a fair one, so here’s the honest version of how this desk works, what it draws on, and why it reads the way it does.

Tree Roots Near Foundations: When to Worry
I’ve handled property damage claims for eleven years, and the file that changed how I look at trees was a modest single-story house with a silver maple standing about nine feet from the corner of the foundation. The owners had lived there for eighteen years with no issues, then one dry summer produced a series of cracks through the foundation wall and a door that stopped closing properly almost overnight. The claim got denied — gradual, foreseeable soil movement from root activity isn’t the kind of sudden event most policies are written to cover — and the homeowners were furious that nobody had ever told them a healthy, established tree could do this to a house that had stood fine for decades.
Soil Type and What It Does to Slabs
I spent six years running penetrometer tests and reading soil reports for a geotechnical firm before I started doing slab assessments on the inspection side, and the sample that changed how I explain this to buyers came from a house in Adelaide with a crack running diagonally across the garage floor. The owner assumed it was a shrinkage crack from when the slab was poured. The soil test told a different story: Keswick clay directly under the slab, no engineered fill between them, and a crack pattern that lined up exactly with where the clay had been drying and shrinking fastest through the previous summer.
Paying for Repairs After the Report: How Small Contractors Get Funded
Twenty-two years adjusting property claims taught me something most people never think about until they’re standing in the middle of it: finding the damage is the easy part. I remember a slab claim outside Fort Worth where the foundation repair company had already jacked and shimmed six piers before the homeowner’s insurance payout cleared, because the contractor couldn’t afford to sit on a signed contract for six weeks waiting on a check. That gap between “the report says fix it” and “the money to pay for fixing it actually lands” is where a lot of small repair contractors quietly go under, and it shows up just as often after a home inspection as it does after an insurance claim.

Stormwater Discharge and the Neighbour Problem
I own three rental houses now, and every one of them taught me something the previous one didn’t, but the second purchase is the one that taught me to ask a question most buyers never think to ask: where does the water go once it leaves this property? The inspection report flagged a downpipe discharging straight onto the side boundary, and I nearly waved it off as a minor drainage note. Then the neighbour introduced himself during the pre-settlement walkthrough, unprompted, to explain that he’d already complained to the previous owner twice about water pooling against his fence line, and that he intended to keep complaining to whoever bought the place next.

Photographing Defects: What Makes an Inspection Report Usable
I once had a report bounced back by a buyer’s attorney because the photo of a water stain on a pre-war ceiling showed nothing but a vague grey smudge with no sense of size, no flash, and no idea where in the apartment it was. The stain itself was real and worth flagging — active leak from the unit above, sheetrock starting to soften — but the photo was useless as evidence. I’ve been doing independent pre-listing and pre-purchase inspections in New York long enough to know that a report lives or dies on whether the photos back up the text, and most inspectors treat photography as an afterthought.

Flashing Failures Around Roof Penetrations
Fifteen years hanging plasterboard taught me more about where roofs actually leak than any classroom ever did, because I was the one called back eighteen months later to fix the ceiling stain nobody could explain. It was never the field of the roof. It was always a penetration — a vent pipe, a skylight curb, a chimney chase — where the flashing had been installed as an afterthought instead of as the first thing planned. On one job in particular, a bathroom exhaust vent through a tile roof, the roofer had dressed the tiles neatly around a flashing collar that was never actually sealed to the pipe itself. Looked immaculate from the ground. Leaked for two years before anyone traced the water back to it.
Slab Edges and Soil Movement: What Inspectors See in Toowoomba
I spent nineteen years pouring and finishing slabs before I picked up a moisture meter for a living instead of a bull float, and the first thing I look for on any Toowoomba job now is the same thing that used to keep me up at night as a concreter: the edge. Not the middle of the slab — the middle rarely moves much. It’s the perimeter, especially the corners, where I found a lift of nearly 15 mm on a house last month, enough that the skirting had pulled away from the tile line in a dead-straight gap you could slide a coin into.

Gutter Slope and Fascia Rot: A Slow, Expensive Pair
The call that taught me to always pull on fascia boards, not just look at them, came from a two-story colonial with gutters that looked fine from the driveway — clean, freshly painted, no visible sag. I climbed the ladder to check the slope with a level, and the fascia board behind the front-left run came away in my hand like wet cardboard. Eight feet of it, soft enough to push a screwdriver through with two fingers, and the buyer had no idea because nobody had ever told her that a gutter can look perfect and still be running water sideways instead of down.

Cut-and-Fill Problems Under the Slab: A Christchurch Inspection View
The crack in the garage floor was only 4 mm wide, but it ran arrow-straight from the roller door corner back toward the house, and it lined up almost exactly with a line I could see in the section’s old survey plan — the point where the original ground had been cut back half a metre to level the building pad. The agent wanted to call it shrinkage. I’d already probed both sides of that line with a hand auger, and the fill side gave way another 40 mm before hitting anything firm. That’s not shrinkage. That’s eleven years of a cut-and-fill pad settling unevenly, and the slab had been quietly telling everyone about it the whole time.
