Water damage and restoration
Leaks, moisture, mold, and structural drying, and the IICRC-driven mitigation that keeps a loss from getting worse.
Calculators for this work
Concrete
Terrazzo flooring install and polish
Prep and test the slab for moisture before epoxy terrazzo, lay the divider strips over the joints to control the cracking, then grind, grout, and polish to expose the chips and fill the pinholes.
Concrete
Slab moisture testing for flooring
Measure how wet the slab is before flooring goes down, test deep with the RH probe, condition the building first, and meet the flooring manufacturer's number or mitigate.
Concrete
Parking structure restoration
Why a garage is concrete under constant chloride attack, and the program that stops the corrosion before it patches the spalls: condition survey, repair behind the bar, anodes, and waterproofing.
Concrete
Masonry repointing and restoration
Why the wrong mortar destroys the wall it was meant to save, how to match the original and cut the joints to depth without wrecking the units, and how to tool the profile and fix the water source above.
Concrete
Slab curling and warping control
Why slab edges and corners lift off the base, what the gradient is doing, and how the mix, the cure, and the joints keep a floor flat instead of curled.
Concrete
Commercial resilient flooring install
Test the slab moisture before a single tile goes down, prep the subfloor, pick the right adhesive for the product, then acclimate, lay out balanced, and document for the warranty.
HVAC
Mold remediation field guide
Mold is a water problem first. Fix the moisture, contain the work under negative pressure, physically remove the mold, and verify with a third-party professional instead of spraying biocide and painting over it.
HVAC
IAQ investigation and testing field guide
Start with the people and the building, check carbon monoxide first, find the ventilation or moisture cause, and fix the source instead of selling a purifier.
HVAC
Fire and smoke restoration field guide
Beat the acidic-residue clock, dry-clean the soot before you wet it, match the chemistry to the residue, and pull the odor out at the source instead of masking it.
HVAC
Commercial ice machine field guide
The refrigeration is the easy part. The water side, the filtration that fights scale, the air-gapped drain, the sizing derate, and the cleaning that keeps mold out are what make or break an ice machine.
HVAC
Refrigerant evacuation field guide
Pull air and moisture out of the system with a deep vacuum, read it in microns on a micron gauge, prove it dry and tight with a decay test, and record what the system held before you charge it.
HVAC
Desiccant dehumidification field guide
Pull moisture out by adsorbing it onto a desiccant instead of condensing it on a coil, reach the low dew points a coil cannot, and plan for the warm dry air that comes back out.
Plumbing
Water damage restoration field guide
Water restoration is a race. Mold can start in 24 to 48 hours, so extract the standing water fast, create a real drying environment, and monitor daily to a dry standard you can prove.
Plumbing
Fire and smoke damage restoration field guide
Fire restoration is three problems at once. Identify the soot type because it dictates the cleaning method, dry the firefighting water first, remove the source, and clean the HVAC, or the odor comes back.
Plumbing
Water mitigation and drying guide
Stop the source, call the category, extract the standing water, then dry the structure to a measured dry standard before mold grows, and document every reading for the insurer.
Plumbing
Contents pack-out and inventory
Move the belongings out, but the job is the inventory: a photographed, tagged, room-by-room record that is the chain of custody and the contents claim.
Roofing
Drone inspection field guide
Fly it legally under Part 107, capture the thermal data that finds what the eye cannot, and hand the trade a report that says where to look.
Roofing
Traffic deck coating
What a traffic coating actually protects, why it is corrosion protection for the deck, the urethane primer-base-aggregate-top system, the surface prep and moisture that make or break the bond, the detailing, the mils, and the testing.
Roofing
Storm and hail damage restoration
How a roofer reads real hail and wind damage, documents the storm claim, and works it ethically and legally: ACV vs RCV, the deductible, supplements, and staying out of public adjusting.
Roofing
Reroof: recover vs tear-off
When to recover the roof and when to strip it to the deck: the two-layer code limit, the moisture survey that settles the call, wind attachment, cost and life, disposal, and staying dry while the deck is open.
Roofing
Roof vapor retarder and air barrier
What the vapor retarder and the air barrier each do in a low-slope roof, why air leakage wets insulation faster than diffusion, which side the retarder goes on, and when the assembly actually needs one.
Roofing
Metal roof restoration
Renewing an aging, rusting metal roof in place: qualifying the roof, treating the rust, fixing the leaking fasteners and seams, and coating it, instead of a tear-off.
