On average, the most rain and snow falls in October

Check your drains and the slope around the house ahead of October. It takes an afternoon, and it can save a lot of drying later.

Before anyone arrives

The first hour after a leak in Portsmouth

You don't have to do all of this. Do what's safe, in this order, and leave the rest.

  1. Shut off the water

    Look for the main valve near the meter or where the line comes into the house, and turn it slowly, since older valves can stick. If it's one fixture, its own shutoff valve will do.

  2. Stay clear of the power

    If you can reach the breaker panel without stepping in water, switch off the wet rooms. If you can't, leave it alone, stay out of the water and tell us when you call.

  3. Take pictures first

    Before you clean up, photograph the water, where it came from and whatever it damaged. Your insurance company will ask, and you only get one chance at those shots.

  4. Rescue what you can

    Move rugs, papers, photos and electronics to a dry room, and prop furniture up off the wet floor. Everything else can wait.

  5. Let the air move

    If the water is clean and the power's safe, open interior doors and run the fans you have. Stay out if it's sewage or floodwater, and keep that air away from the rest of the house.

You've got about 24 to 48 hours to start drying before rot and mold become the bigger problem.

Typical build year

What to check around Portsmouth before it leaks

By now, most homes from this era have had some plumbing replaced, and the leftover sections are usually the risk. Look for gray galvanized pipe next to newer copper or plastic, because those joints can corrode. If you've had a few sewer backups, the old line itself may be the cause.

It's also worth replacing rubber washing machine hoses with braided steel. It's a ten-minute job, and those hoses cause a surprising number of flooded laundry rooms.

How we can help in Portsmouth

The Northeast

What's different about water damage in Portsmouth

Weather

Cold drives much of the damage here. Long freezes split pipes in outside walls, ice dams force meltwater under shingles, and nor'easters bring heavy snow, rain and coastal flooding together. The remains of a tropical storm can also stall over the region and flood rivers far inland.

Buildings

This is some of the oldest housing in the country. Stone and brick foundations let groundwater seep through, plaster walls and hardwood floors need slow drying, and radiators and steam systems add old pipework that can fail with little warning.

Ground

Dig down a little around here and you'll often hit rock. Water can't go through it, so it moves along it, and if your foundation's in the way, it comes in. A damp cellar after a rainy week is very often groundwater, not a leak.

Drying

Water won't leave a cold wall quickly. Bringing in controlled heat warms the materials and speeds things up, and dehumidifiers catch what comes out. That's especially useful with stone foundations and old plaster.

When you call

From phone call to dry house in Portsmouth

It starts with a few quick questions: your address, what happened and how long it's been wet. Then we'll connect you with someone from our network who works in Rockingham County. Your own home, a rental or a business, you'll know what's next before the call ends.

Before any equipment goes in, the specialist needs to know two things: how far the water got, and how dirty it is. Thermal cameras and moisture meters answer the first. For the second, there are three answers: Category 1, clean water, Category 2, dirty water, or Category 3, sewage and floodwater. With Category 3, plastic containment goes up and negative air machines with HEPA filters keep your house's air clean.

Drying is a process, and you'll have strange machines in the house for a few days. The bulk of the water goes first, by truck-mounted or portable extractor. Air movers then lift moisture off surfaces, and low grain refrigerant (LGR) dehumidifiers remove it from the air. A cold building or dense material may need desiccant units instead. Daily psychrometric readings show if the air is still pulling water out.

A wall can feel dry and still hold plenty of water. That's why the specialist measures a dry standard from unaffected wood and drywall nearby and keeps the equipment running until the wet areas match. This is the method in the IICRC S500 standard, and those moisture logs back up your insurance claim.

What comes out and what stays in a Portsmouth home

More than you'd think, if it's caught early. Carpet soaked with clean water can often be dried in place once the pad's been pulled. Hardwood is worth trying to save too, with floor drying mats and slow drying, though it may need refinishing. Drywall that's wet only at the base can be cut a little above the waterline instead of being replaced to the ceiling, which is what a flood cut is.

Sewage and floodwater are a different story. Carpet they've touched has to go, and what stays gets cleaned and treated with an antimicrobial. Two more things to check before you use the room again: a gas appliance that sat in water, and any floor that feels soft underfoot.

Portsmouth water damage questions

How fast can someone get to me in Portsmouth?

Usually the same day, and often within a few hours. It depends on who's closest and how busy Rockingham County is. If a storm has just gone through, everyone's calling at once, so call as soon as you can.

Can I clean up water damage myself?

A small spill of clean water on a hard floor? Sure. Towels and a fan will do it. But if the water's in the walls, the carpet pad or the subfloor, or it came from a sewer or a flood, you'll want it extracted and properly dried. What you can't see is what keeps causing damage.

How long does it take to dry out a house?

A small leak that's caught early may dry in two or three days. A flooded room with wet subfloor and insulation can take a week or more, and repairs start after that.

Can wet hardwood floors and carpet be saved?

Hardwood is more forgiving than people think. Floor drying mats pull moisture up through the boards, and refinishing can take care of what's left. Carpet can usually stay if the water was clean, as long as the pad's replaced. If the water was dirty, it can't.

Will my insurance pay for water damage?

That's between you and your insurance company, but most policies cover sudden water damage from inside the home. Flood is separate, and sewer backup is often an add-on. Your best help is good records: photos from the start, plus the daily drying readings.
