Randolph’s pre-1980 homes often feature brick-lined air ducts, which trap dust, mold, and insulation fragments far more aggressively than modern systems. Our proprietary process uses soft-bristle brushes and HEPA-vacuum extraction to dislodge decades of buildup without damaging fragile masonry or liners. We seal off work areas to prevent dust migration into living spaces, and our Randolph-specific protocols account for local humidity levels that accelerate mold growth in older ductwork. Homeowners report improved airflow, reduced allergy symptoms, and lower HVAC strain—often within 24 hours of cleaning. Each project includes a post-cleaning inspection with infrared imaging to verify debris removal from every register and junction.

Our Randolph team uses microfiber whip tools and antimicrobial treatments to neutralize odors and inhibit future buildup, especially critical in homes near the Blue Hills Reservation where seasonal pollen infiltrates ducts. Unlike generic ‘duct cleaning’ services, we focus on the entire system—from main trunk lines to individual vents—ensuring no section is overlooked. All work is backed by a 1-year performance warranty, and we provide before/after particle counts to prove the difference.
Request this service →Mold in Randolph’s older homes often stems from hidden moisture in brick-lined ducts or poorly sealed masonry chimneys. Our Randolph specialists use HEPA-filtered containment barriers and EPA-registered antimicrobial solutions to eliminate mold at the source, not just mask odors. We test air quality pre- and post-cleaning to confirm spore counts drop to safe levels, and our Randolph-specific approach includes inspecting attic insulation and crawl spaces for cross-contamination. All mold remediation projects include a 5-year warranty against recurrence, and we document every step for insurance claims if needed.
Request this service →Randolph’s brick chimneys—common in homes along North Main Street or near the MBTA station—accumulate creosote and soot faster than modern systems, posing fire risks and reducing draft efficiency. Our Randolph team uses rotary brushes and high-powered vacuums to remove buildup from flues, while our camera inspections identify cracks or liner gaps that compromise safety. Unlike generic chimney sweeps, we focus on the entire masonry system, including smoke chambers and crowns, to prevent water intrusion. All Randolph chimney cleanings include a Level 2 inspection report, required for home sales and insurance underwriting.
Request this service →Randolph’s historic homes often have undersized or leaky ductwork, forcing HVAC systems to work overtime and driving up energy bills. Our Randolph specialists perform a full system audit, using anemometers to measure airflow at every register and thermal imaging to detect hidden leaks in brick-lined trunks. We seal gaps with masonry-safe sealants and adjust dampers to restore proper balance, often improving efficiency by 20% or more. All optimization projects include a 2-year follow-up inspection to ensure lasting performance, and we provide Randolph-specific recommendations for upgrading insulation or adding booster fans if needed.
Request this service →Randolph’s older homes are vulnerable to water damage from aging pipes or roof leaks, which can turn ductwork into a breeding ground for mold and bacteria. Our Randolph team responds within 2 hours for emergency cleanings, using desiccant dehumidifiers and antimicrobial fogging to dry and sanitize ducts before mold sets in. We work directly with local Randolph insurance adjusters to document damage and expedite claims, and our Randolph-specific protocols prioritize homes near the Randolph Community Pool or along the Neponset River corridor, where humidity levels are highest. All emergency cleanings include a moisture meter report to prove the system is fully dry.
