A flooded basement means mold risk, structural damage, and destroyed belongings. BostonWaterHelp matches you with a licensed remediation specialist in minutes — 24/7, including during nor'easters.
Greater Boston's geography, climate, and aging housing stock create a perfect storm for basement flooding year-round — not just in spring.
Boston averages 5–7 nor'easters per winter season. A single storm can dump 12+ inches of snow or rain, overwhelming storm drains and sending water straight into basements through foundation cracks.
March and April are Boston's highest-risk months. Snowpack from multiple winter storms melts rapidly, saturating the water table and pushing groundwater through foundations and floor drains.
Boston's stormwater system in many neighborhoods dates to the early 1900s. Combined sewer/stormwater overflow events during heavy rain force sewage backup into residential basements.
Boston's high water table means many homes rely entirely on sump pumps. A pump failure during a storm — especially a power outage — results in rapid basement flooding within hours.
Most Boston triple-deckers, colonials, and Victorian homes were built with fieldstone or early concrete foundations prone to settling cracks — which grow into major leak points over decades.
Winter ice dams on Boston roofs force meltwater beneath shingles, through exterior walls, and sometimes down into basement walls — appearing as mysterious interior leaks days after a storm.
When a licensed restoration professional arrives, here's what they do — and why each step matters.
Checks for electrical hazards, gas leaks, and structural instability before entering the flooded area. No professional should skip this step — neither should you.
Industrial truck-mounted or portable extraction units remove standing water. A submersible pump handles deep flooding; wet-vacs handle residual water from carpet and concrete.
Thermal imaging and moisture meters identify hidden water in walls, floors, and framing that isn't visible to the eye. This is what separates a real restoration from a mop job.
Commercial dehumidifiers and air movers dry the space to pre-loss moisture levels — typically over 3–5 days. Readings are logged daily for insurance documentation.
Affected surfaces are treated to prevent mold growth. In contaminated water events (sewage backup), disinfection protocols are more extensive and include disposal of porous materials.
The pro provides a written scope of work and photo documentation for your insurance claim. Reconstruction — drywall, flooring, paint — begins after the structure is fully dry.
Boston homeowners are often surprised to learn that standard homeowner's insurance has important exclusions for basement flooding. Here's what you need to know before filing a claim.
If the flooding came from a burst or frozen pipe, it's likely covered under your homeowner's policy as a "sudden and accidental" water event. Document the pipe before repair.
Water that enters through foundation cracks, window wells, or overland flow is typically excluded from standard homeowner's policies. You need separate flood insurance (NFIP or private).
Most policies exclude sewage backup by default. A "water backup" endorsement (typically $50–$150/year) covers sewage and drain backup events. Check your policy now, not after a flood.
Take timestamped video of all damage before moving anything. Photograph water lines on walls, affected belongings, and the suspected entry point. Insurers require evidence.
Your policy likely requires you to take reasonable steps to prevent further damage. Starting cleanup doesn't invalidate your claim — waiting does. Get a restoration company started now.
The restoration professional's moisture logs, extraction receipts, and drying reports are evidence for your adjuster. Professionals matched through BostonWaterHelp provide standard documentation.
