Water Damage Restoration - Done in the Right Order
Each stage is performed by the independent restoration contractor the call reaches; IICRC S500 is the industry standard that describes them.
-
Step 1: Extraction
Standing water is pumped out before it can travel further into drywall, subfloor, and framing. Speed here changes the scope of everything that follows.
-
Step 2: Moisture mapping
Meters read the material, not the air, so the wet edge is found even when the surface already looks dry. The map sets what has to come out and what can stay.
-
Step 3: Drying
Air movers and dehumidifiers run as a closed system until readings inside the material reach a dry standard, not until a calendar date arrives.
-
Step 4: Verification
The same points are re-read before equipment comes out. Rebuild starts only after the structure, not just the surface, is confirmed dry.
What drives water into buildings in Portsmouth
Our local pros provide water damage restoration services in Portsmouth and the surrounding area, including Portsmouth Plains and Meadowbrook. A tidal Piscataqua port with a dense historic core, where four fifths of the housing predates 1990 and October is the wettest month of a forty-nine inch year.
Housing stock
Over four fifths of the housing here predates 1990 — 79.3 percent of it — and construction settles around a median year of 1959. Much of the stock is genuinely old: eighteenth and nineteenth century wood and brick in the core, over stone and rubble cellars, alongside later infill. The river here has one of the strongest tidal currents on the east coast, and the low streets nearest it sit only a little above high water.
Climate and water risk
Portsmouth averages 49.42 inches of precipitation a year on the 1991–2020 normals, taken at ELIOT 2.9 miles away, with October the wettest month at 4.83 inches. October brings the wettest month at the start of the coastal storm season, when a surge on top of a high tide can raise the river well above its normal range. Rain falling during those hours has nowhere to discharge, so the low ground takes both the storm's water and its own.
Common water damage problems in Portsmouth
- Storm surge on high tides raising a strong tidal river above the low streets
- Historic wood and brick over stone cellars with no drainage provision behind the walls
- Rain and surge coinciding, so the drainage has no head to discharge against
- Freeze and thaw acting on saturated stone foundations through a coastal winter

Storm & Flood Recovery
From wind-driven rain to flash flooding, local professionals secure the property, extract standing water, dry the structure, and document all damage for the claim. Interior and exterior stabilization is handled to prevent secondary losses.
Learn more - Fast Response
Groundwater & Basement Intrusion
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat.

Ceiling & Roof Leak Water Damage
Water-stained or sagging ceilings are professionally dried, treated, and restored after roof failures, plumbing leaks, or upstairs overflows. Moisture is removed from the structure, damaged material is safely taken out, and the area is stabilized.

Frequently asked questions
The low streets flood on a storm tide with no rain.
That is coastal flooding rather than a drainage fault, and it is worth distinguishing because the responses differ. A surge on top of an already high tide raises the river above the level of the low streets, and the drainage that normally discharges there is under water. Nothing is blocked. The astronomical tide combined with the surge forecast predicts it far better than any rainfall figure.
Can an eighteenth century cellar be kept dry?
Manageably damp is the honest target. A stone or rubble wall has no continuous surface to seal, and coatings applied inside tend to move water rather than stop it, sometimes into the mortar higher up. What works is managing water before it reaches the wall with grading and roof drainage, then handling what still arrives with an interior drain and a sump. Expecting a finished dry room out of that space is what leads to expensive disappointment.
Is there anything specific about historic materials after a flood?
Yes, and it argues for slower drying rather than faster. Old plaster, lime mortar, and original woodwork can be damaged by aggressive drying as much as by the water, and replacing them is rarely straightforward. A contractor experienced with historic fabric will use gentler drying over a longer schedule and will know what can be saved. It is worth asking about that experience specifically before work starts in the core.
