Backcountry homes see real winters with overnight freezes, dry summers, and long unoccupied periods on vacation properties. Tecate flooring installs favor engineered hardwood and porcelain tile that tolerate wide humidity swings without cupping or gapping. We schedule mountain work around weather windows.. We account for local conditions in every job.
How flat does the subfloor need to be?
Most modern flooring (LVP, laminate, engineered) calls for 3/16 inch in 10 feet. Large-format tile is 1/8 inch in 10 feet. Solid hardwood is 3/16 inch in 6 feet. We measure with a 10-foot straightedge and feeler gauges. Out-of-tolerance areas get self-leveling compound or grinding.
How do you test slab moisture?
Two methods. Calcium chloride (ASTM F1869) measures moisture vapor emission rate over 60 to 72 hours and gives a number in pounds per 1,000 square feet per 24 hours. In-situ relative humidity probe (ASTM F2170) measures moisture inside the slab itself and is more accurate. We default to in-situ probes on slab installs.
