A crawl space sump pump basin is an incredibly effective tool for managing groundwater, but it introduces an unintended indoor air quality hazard: it acts as a direct conduit for radon gas. Radon is a naturally occurring, radioactive, odorless gas produced by the radioactive decay of uranium inside earth soils. Because a sump basin penetrates … Read more
When a home develops sticking door frames, cracked drywall headers, or sloping floors upstairs, homeowners almost always assume the concrete foundation footings are sinking into the dirt. However, in properties plagued by chronic crawl space moisture, the root cause is frequently a different failure: sill plate crushing. The sill plate, or mud sill, is the … Read more
Standard smart water leak sensors are excellent tools for warning you after your crawl space basin has already overflowed. However, if you want to run a proactive water management network, you need a telemetry setup that alerts you before the flood ever happens. You can achieve this level of early warning capability by monitoring a … Read more
Many homeowners upgrade from traditional fiberglass batts to rigid foam boards or closed-cell spray foam insulation to prevent mold and moisture tracking. While these polyurethane materials excel at blocking vapor, they introduce a distinct logistical challenge: rodent tunneling. Mice, rats, and chipmunks love the high thermal insulation properties of foam panels. They will chew their … Read more
When executing a high-performance crawl space encapsulation, the natural instinct is to roll the white polyethylene sheeting all the way up the concrete block walls and pin it directly flush against the wooden sill plate. While this seems like the neatest way to stop concrete block sweat, it creates a massive structural vulnerability that violates … Read more
Sealing your foundation vents and laying down a heavy-duty vapor barrier is the absolute best way to control relative humidity. However, if your under-house footprint contains a gas-fired furnace, a propane water heater, or an older atmospheric boiler, complete encapsulation introduces a dangerous physical complication known as the combustion air paradox. Gas-burning appliances are atmospheric … Read more
Venturing underneath your home to perform a structural checkup, investigate a mysterious musty odor, or audit an encapsulation system can be an incredibly intimidating task. Crawl spaces are dark, cramped, unconditioned microclimates filled with fine dust, sharp wood splinters, dropping insulation fibers, and hidden structural moisture hazards. If you crawl down there unprepared without the … Read more
For the vast majority of homeowners, the dark, unconditioned space beneath their floorboards is a classic case of out of sight, out of mind. However, treating your crawl space with passive neglect is a dangerous financial strategy. Over the course of a single year, shifting soil profiles, intense seasonal rainstorms, freezing winter drafts, high summer … Read more
Operating a primary submersible sump pump in your crawl space basin provides great peace of mind during typical seasonal rainstorms. However, relying entirely on a single pump plugged into a standard wall outlet is a dangerous gamble. The exact moments you need your water management system the most—during violent thunderstorms, flash floods, and severe weather … Read more
When homeowners shop for a commercial crawl space dehumidifier, they almost always make their final purchase based on a single metric: the square footage rating printed on the box. They look at a machine that says “rated for 1,500 square feet,” match it to their 1,400-square-foot footprint, and assume they have found the perfect solution. … Read more
