Basement or ground floor flooded?

Flood water carries silt, runoff, and bacteria into every porous surface it touches. Proper cleanup removes the contamination — not just the water.

What flood damage cleanup covers

Flood cleanup differs from a clean pipe leak: the water is contaminated. Runoff crossing lawns, roads, and septic zones carries soil, oils, and microbes into basements and crawl spaces. Crews remove what absorbed it, sanitize what remains, and dry to verified targets.

  • Contaminated water removal — pumps and extraction units clear stormwater, meltwater, and groundwater from basements, crawl spaces, and ground floors.
  • Flood-line tear-out — soaked carpet pad, wet insulation, swollen trim, and drywall below the water line are cut out and bagged for disposal.
  • Mud and debris removal — silt left as water recedes is cleared so surfaces can actually be cleaned.
  • Cleaning and sanitizing — framing, concrete, and salvageable surfaces are cleaned and treated to cut odor and microbial risk.
  • Structural drying — air movers and dehumidifiers run for days in cool below-grade spaces until meters confirm targets.
  • Rebuild scoping — replacement drywall, insulation, flooring, and trim are measured and scheduled, tying into water damage restoration.

Flooded basements are the most common call — see basement water damage for below-grade specifics. Browse every option on the services page.

Warning signs you need flood cleanup now

Call (888) 217-5329 right away if you find:

  • Inches of water in a basement, crawl space, or garage after rain, melt, or surge.
  • A visible water line on walls showing the flood already peaked and soaked in.
  • Mud, silt, or foul odor left as water drains away.
  • Floor drains backing up in heavy rain — wastewater means sewage cleanup protocols.
  • Damp block walls, weeping floors, or rust at the furnace base after an event.
  • Musty growth spreading on lower walls or stored contents within days of the flood.

Flood-soaked porous materials rarely dry clean — early tear-out keeps contamination out of framing that can be saved.

How flood cleanup works, step by step

From first call to verified dry.

Step 1

Call Now

Call (888) 217-5329 day or night. Note the source, depth, backups, and affected heating equipment.

Step 2

Rapid Assessment

The crew maps the flood line, checks the water category, and marks materials for removal.

Step 3

Extraction & Dry-Out

Contaminated water is pumped out, ruined materials removed, surfaces sanitized, then drying runs with daily readings.

Step 4

Restore & Verify

Final meter checks confirm dry structure before repair scoping for walls, floors, and trim.

Call immediately if:
flood water reaches outlets, the panel, or gas appliances — stay out and have power and gas checked before re-entry; drains are backing up with wastewater — avoid all contact and keep pets and children clear; foundation walls bow, shift, or crack with water pressure — leave the basement entirely. Then call (888) 217-5329 for 24/7 dispatch.

New Hampshire flood causes, season by season

Every season sends water toward Granite State foundations in a different way.

  • Nor'easters — coastal wind and surge drive water into Seacoast basements around Portsmouth and Dover, often through bulkheads and window wells.
  • Spring melt — deep snowpack melting into frozen ground has nowhere to go but toward foundations, flooding cellars from Laconia to Keene.
  • Summer downpours — short, intense storms overwhelm gutters and grading in Manchester, Nashua, and Concord subdivisions.
  • Merrimack River rise — river towns take on groundwater that seeps through slabs and joints days after the crest passes.
  • Sump pump failures — outages and worn-out pumps quit mid-storm; battery backup and correct sizing prevent repeats.
  • Frozen pipes and ice dams — winter's version of flooding: burst lines and backed-up meltwater that soak attics and walls. Urgent pump-out is covered under emergency water extraction.

Dampness that returns without a clear event means chronic seepage — and lingering growth belongs under mold remediation.

Flood cleanup questions, answered

Straight answers before you call.

Is flood water dangerous to clean up myself?

Yes. Stormwater and groundwater carry soil, road runoff, fuel residue, and sometimes sewage. Wear boots and gloves, keep children and pets out, and call (888) 217-5329 so an equipped crew handles removal.

What gets removed during flood damage cleanup?

Flood-soaked carpet pad, wet insulation, swollen laminate and particle board, and drywall below the flood line are typically removed. Solid wood framing and concrete are cleaned, sanitized, and dried in place when readings allow.

How long does basement flood dry-out take in NH?

Most basements need 3 to 5 days of monitored drying after pump-out — longer for stone foundations, finished walls, or cold slabs. Equipment stays until meter readings hit target.

Does homeowners insurance cover flood cleanup in New Hampshire?

Standard policies usually exclude groundwater and river flooding without separate flood coverage, though storm-driven rain entering through wind-damaged roofing may be treated differently. Document water lines with photos and keep damaged materials until your adjuster advises.

How do I keep the basement from flooding again?

Common steps include regrading soil away from the foundation, extending downspouts, testing the sump pump and adding battery backup, sealing bulkhead gaps, and installing a dehumidifier. The crew on site can point out which fixes match your home.
