Foundation, basement, and crawlspace

A pre-repair foundation crack checklist for documenting location, width and pattern, movement indicators, displacement, water entry, soil and drainage context, wall type, prior repairs, nearby openings and loads, urgent safety triggers, structural or geotechnical referral, monitoring, and evidence before sealant, patching, paint, or finish work hides the condition.

A pre-finishing basement moisture checklist for rain and seasonal history, foundation and slab leakage, condensation, plumbing and HVAC sources, exterior grading and drainage, sump and drain behavior, humidity, material condition, mold or odor concerns, drying verification, radon planning, and release criteria before framing, insulation, drywall, flooring, cabinets, or stored contents hide vulnerable surfaces.

A homeowner basement-waterproofing proposal checklist for comparing diagnosis, exterior versus interior scope, drainage path, footing drains, sump and discharge, crack and wall treatment, excavation limits, structural and utility risks, mold or finish removal, permits, testing, warranties, exclusions, price allowances, restoration, maintenance, and proof of performance before signing.

A pre-backfill existing-home foundation waterproofing checklist for excavation safety, exposed-wall condition, structural cracks and repairs, substrate preparation, selected dampproofing or waterproofing system, seams and penetrations, footing drains, aggregate and filter layers, insulation and protection board, window wells, utilities, discharge, inspection, photographs, wall bracing, and controlled backfill before the work disappears.

A pre-concrete interior basement perimeter-drain checklist for slab-cut limits, dust and contamination controls, footing and wall condition, trench depth, pipe type and slope, aggregate and filter materials, wall drainage interface, sump basin connection, radon and vapor-control continuity, utilities, structural restrictions, cleanouts, inspection, test records, photographs, and concrete restoration before the drainage work is permanently covered.

A pre-acceptance sump-system checklist for basin size and lid, primary and backup pump compatibility, capacity and head, float movement, check valves, discharge piping, supports, freeze and backflow risk, power and protective devices, battery location and age, alarms, generator or water-powered interfaces, test volumes, failure simulation, maintenance access, owner instructions, and documentation before the basement relies on the system.

A pre-encapsulation crawlspace drainage checklist for safe access, exterior runoff, crawl grade and low points, groundwater and flood conditions, foundation and pier condition, perimeter drains and sumps, plumbing and HVAC leaks, sewage or pest contamination, discharge, erosion and sediment control, radon planning, inspection, drying, and photographs before a vapor barrier or insulation hides the ground and foundation interfaces.

A final crawlspace encapsulation checklist for ground and wall liner type and continuity, seams and terminations, piers and penetrations, radon and soil-gas compatibility, wall insulation and termite inspection details, vents and air sealing, drainage access, sump and alarms, dehumidification or conditioned-air strategy, condensate, electrical safety, access and service clearances, humidity monitoring, cleanup, warranties, and owner maintenance before final payment.

A foundation stabilization records checklist for approved engineering, geotechnical basis, permit and utility coordination, excavation safety, pier or underpinning layout, product identification, installation depth or resistance, torque or pressure data, bearing or grout records, bracket and connection details, lift plan and measured response, structural monitoring, drainage and waterproofing restoration, special inspection, warranties, final report, and post-work observation before payment or concealment.

A pre-finish basement emergency-escape and rescue opening checklist for room and sleeping-use requirements, approved opening and window product, clear opening dimensions and operation, sill height, window-well size and projection, ladder or steps, drainage, cover release, guard and fall conditions, foundation cut and structural support, lintel and reinforcement, waterproofing and flashing, insulation and air sealing, exterior grade, permit inspection, photographs, and interior clearance before walls, trim, flooring, landscaping, or furniture limit the opening.

A pre-drywall finished-basement checklist for moisture release, wall and floor assembly design, framing separation from masonry, continuous air and thermal control, insulation type and installation, rim joists, vapor-control strategy, fireblocking and draftstopping, stairs and soffits, penetrations and utility protection, electrical and plumbing rough-ins, combustion and HVAC clearances, egress, flood and termite limitations, inspection approval, and complete photographs before finishes conceal the work.

A pre-occupancy basement radon-testing checklist for selecting the correct lower-level test location and method, checking state and professional requirements, device quality and placement, closed-building and HVAC conditions, interference controls, test timing after construction and ventilation changes, occupancy and weather records, result interpretation, confirmation or mitigation decision, qualified contractor selection, mitigation-system commissioning, post-mitigation retest, owner documentation, and ongoing retesting before a basement becomes regularly occupied.
