Inspection & Assessment in Landmark

Landmark, east of the Red River in the RM of Taché, is a farming community that has grown into a commuter town while keeping much of its original rural housing stock. Those older homes are where we do most of our crawlspace work. They sit on heavy clay, typically on shallow footings, and many have crawlspaces that were excavated just deep enough to run services. Soil floors, open vents and batt insulation between the joists are the standard configuration, and it is an assembly that fails slowly and invisibly in our climate.

The clay around Landmark drains poorly, so snowmelt and heavy rain stay at the surface and move laterally. Foundation backfill is the easiest route down, which is why so many crawlspaces here take water in the first warm week of spring, while the subsoil is still frozen and nothing can percolate. Through summer, the same spaces swing the other way: humid outside air enters through vents, condenses on cool soil and framing, and keeps wood moisture content in the range where mould thrives. By the time there is a smell in the house, the framing has usually been damp for years.

For rural properties like these, we build systems that run unattended. Drainage is installed where the water actually arrives, with a sump and freeze-resistant discharge routed well clear of the foundation and septic field. The barrier is reinforced, mechanically fastened, and sealed at every well, septic and plumbing penetration. Insulation moves from between the joists to the perimeter wall so the floor assembly stays warm and dry, and the space is brought into the conditioned envelope. Where we find tipped piers or soft sill plates, structural repair comes first so the rest of the system has something stable to seal against.

Calls from Landmark are mostly from owners of the older rural housing stock, and they tend to arrive after someone has finally gone into a crawlspace that had been left alone for years. The findings are consistent: soil floor, open vents, batts sagging out of the joists, elevated framing moisture, mould on the subfloor sheathing, and sometimes a pier that is no longer bearing properly. The second category of call is seasonal — water in the first warm week of spring, gone by June.

Rural systems have to run without supervision, which drives our specifications. Mechanically fastened barriers rather than loose poly. Sumps with freeze-resistant discharge routed clear of the septic field. Dehumidifiers with permanent drains. A high-water alarm where a failure would cause real damage. And insulation at the perimeter rather than the ceiling, so well lines and plumbing in the space are protected by ambient temperature rather than by pipe sleeves alone.

Our first recommendation on a Landmark property is almost always exterior water management plus a structural assessment, in parallel. The exterior work is cheap and removes much of the load on dense clay. The structural assessment tells you whether the piers and sill plates can support a sealed system or need correction first. Together they define the project, and we would rather establish both before quoting anything.

A crawlspace inspection is worth doing properly because almost everything that follows depends on it. We go into the space rather than looking through the hatch, and we work through a consistent sequence: moisture content readings in joists, sill plates, beams and subfloor sheathing at multiple locations; relative humidity and temperature in the space; the condition and height of any efflorescence or staining on walls; the state of insulation and vapour barrier if present; visible mould and where it is concentrated; evidence of pest activity; and the condition of mechanical equipment, drainage and sump if installed.

Structure gets equal attention. We check bearing at posts and piers, look for section loss at sill plates and beam ends, measure floor level where sagging is suspected, and look for the signatures of frost movement and clay shrinkage — diagonal cracking, tipped piers, posts no longer bearing fully, separation at additions. In Winnipeg the single most common structural finding is support that was never founded below frost depth, so we specifically determine founding depth wherever it can be established.

The diagnostic question that matters most is where water comes from, because it determines the entire scope. Surface water from roof discharge, negative grading or snow storage is solved outside and cheaply. Groundwater rising seasonally needs interior drainage and a sump. Condensation driven by a vented, unconditioned space needs sealing and insulation. A plumbing leak needs a plumber. These look similar once there is water on the floor, and getting it wrong means spending money on the wrong system — which is why we trace the path rather than guessing from the symptom.

You get the findings in writing, with photographs and the actual readings. We prioritize what we found into what is urgent, what should be planned, and what can be monitored. Not every crawlspace needs a full encapsulation, and we will say so when the right recommendation is grading and downspouts plus a follow-up reading next spring. A documented baseline is also useful well beyond our work: it helps with real estate transactions, insurance discussions and simply knowing whether things are getting worse.

Inspections are also worth doing before you buy. A home inspector will note crawlspace conditions, but the scope is necessarily broad and the time in the space is limited. If you are purchasing a home in Winnipeg or a surrounding municipality with a crawlspace, particularly a pre-1980 property or one with additions, a focused assessment tells you what you are taking on: whether the support is founded below frost depth, whether the framing has active decay, whether the space takes water, and what remediation would realistically cost. That is information worth having before closing rather than after.

The instruments we use are not exotic, but they matter. A pin-type or pinless moisture meter gives framing moisture content, which is the single most decision-relevant number in a crawlspace; readings are taken at multiple points because a space can be fine at the access hatch and saturated in a far corner. A thermo-hygrometer records temperature and relative humidity, which together establish the dew point and tell us which surfaces are at condensation risk. A bright light and a probe find section loss that looks like staining. Where access is impossible, a borescope or inspection camera lets us see into a space we cannot enter, and we will be explicit about what that does and does not establish.

We also document what is working, not only what is wrong, and homeowners tell us this is the part other reports leave out. If your grading is good, your downspouts are extended, your framing is dry and your piers are founded properly, that belongs in writing just as much as a problem would — it is the baseline you compare against in five years, and it is evidence if a future contractor tells you the space needs work. A report that lists only deficiencies is a sales document. A report that records conditions is an asset.

On access limitations we would rather be blunt than imply a completeness we cannot deliver. A crawlspace with less than about 450 millimetres of clearance, or one heavily obstructed by ducting and plumbing, cannot be fully traversed, and anyone claiming a comprehensive inspection of such a space is overstating it. In those cases we report what we assessed, what we could not reach, and what we would recommend to make the space inspectable — frequently cutting a larger permanent access opening, which pays for itself over the remaining life of the building in every future service visit.
