Onsite Pro Restoration: Precision Mitigation for Los Angeles Homes and Businesses Onsite Pro Restoration is a standards-driven damage restoration company serving greater Los Angeles with 24/7 response for water damage, mold remediation, sewage cleanup, and fire/smoke mitigation. We specialize in complex, high-finish environments—historic plaster, premium hardwood, custom cabinetry, and stone—and we design scopes that protect value while meeting IICRC S500/S520 guidelines. Our mission is simple: contain the loss fast, dry or remediate thoroughly, document every step, and return the property to pre-loss condition with the least invasive path. What sets us apart Standards and documentation first. Every project starts with a defensible scope aligned to IICRC S500 (water) and S520 (mold). We record baseline conditions, establish drying or remediation goals, and document containment, pressure, and equipment performance. That documentation shortens adjuster reviews and reduces rework. Discreet work in sensitive settings. Many of our assignments involve estate managers, HOAs, security teams, and tight access windows. We arrive with floor and stair protection, quiet equipment strategies, and clean site practices. Containment gets set before a single cut, and we maintain directional airflow and negative pressure to keep unaffected areas clean. Advanced diagnostics, minimal demolition. We pair thermal imaging and pin-type/relative moisture meters with targeted opening to find true wet boundaries. That allows us to save finishes other firms might remove, which reduces construction time and cost. Air quality controls as a default. We run true HEPA air scrubbers sized to the space, use pre-filters to maintain rated airflow, and capture sub-micron particles during demo and cleaning. Returns get sealed, tools are shrouded and connected to HEPA vacuums, and we verify cleanliness with HEPA-vac and wet-wipe protocols. Transparent pricing and calculators. To help homeowners plan, we publish interactive cost calculators for mold remediation and emergency water damage. Inputs like square footage, materials, and complexity drive an immediate estimate and a clear line-item breakdown. This educates clients and reduces friction during claims. Tight project communication. Clients receive clear timelines, access notes, daily moisture logs, and photo updates. Adjusters get the documentation package they need: cause-of-loss notes, psychrometric data, drying charts, and chain-of-custody records for any tests. Founder and leadership Onsite Pro Restoration is led by project supervisor and owner Pete Mantizian, who built the company around a field-tested principle: most restoration failures are process failures. Pete’s background in managing multi-trade projects across Los Angeles—single-family homes, hillside properties, luxury condos, and small commercial spaces—shaped our emphasis on scope accuracy, containment discipline, and proof-of-performance documentation. The team culture is calm and methodical: protect finishes, control variables, and verify results before demobilizing. Interesting facts about our business High-finish preservation focus: We often save premium hardwood and custom cabinetry by using floor-drying mats, sectional tenting, and controlled dehumidification to limit cupping, gapping, and veneer delamination. Plaster expertise: Plaster behaves differently than drywall. Our scopes account for longer moisture retention and the need for gentle, low-vibration demo when removal is unavoidable. Estate and HOA coordination: We routinely work under quiet-hour rules, elevator reservations, and security escorts, with unit-specific photo logs to satisfy building management. Calculator-guided transparency: Our public calculators reflect real pricing logic. They set expectations early, which reduces disputes and surprises. Verification mindset: We emphasize “clean finish” steps—HEPA-vac, detergent wet-wipe, recirculated HEPA scrub—to capture settled particulates before clearance or handoff. Future-ready operations: We invest in moisture mapping, job telemetry, and structured reporting so adjusters and property managers can audit outcomes quickly. Core services Water damage restoration: Source control, extraction, selective removal, containment, negative pressure, dehumidification, targeted heat, daily moisture monitoring, and data-backed dry-standard verification. Mold remediation: Cause-of-moisture assessment, engineering controls, removal of contaminated materials, HEPA air filtration, detailed cleaning, and post-remediation verification protocols consistent with industry guidance. Sewage and category 3 cleanup: Rapid containment, gross removal, disinfection with appropriate dwell times, and controlled dry-back with strict PPE and disposal procedures. Fire and smoke mitigation: Soot containment, corrosion control for metals, odor mitigation strategies, and careful cleaning of affected porous and non-porous surfaces. How we work Assessment and scope: Thermal and moisture mapping to define affected assemblies and choose the least invasive plan. Containment and controls: Hard barriers where needed, sealed returns, zipper doors, directional airflow, and HEPA filtration sized to volume. Execution: Precise demo where required, controlled drying or remediation, daily readings, and adaptive equipment placement based on the data. Verification and turnover: Dry-standard confirmation, cleanliness verification, and a clean worksite ready for repairs or immediate use. Documentation package: Photos, equipment logs, moisture charts, and scope notes prepared for insurance and owner records. Compliance and assurance We align our scopes with IICRC S500/S520 and follow EPA and local guidance where applicable. Our teams maintain appropriate licenses, insurance, and safety training. We do not oversell testing or demolition. We explain when testing adds value and when disciplined moisture verification is sufficient. Who we serve Homeowners and estate managers across Los Angeles neighborhoods, from hillside bungalows to architectural moderns and luxury condominiums HOAs and property managers who need unit-specific documentation and quiet, clean work Small businesses that require rapid reopen strategies with minimal disruption Why partners and publishers feature us Clarity for readers: Our articles, calculators, and checklists translate restoration jargon into plain language with practical steps. Evidence-based approach: We share the “why” behind scopes, from psychrometrics to material response, which helps owners make informed decisions.
