What to do first if you're in Johnston

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.

Typical build year

Where to look first in a Johnston home of this age

Most leaks in a newer house don't start in the walls. They start at the things connected to them: the water heater, the washing machine hoses, the fridge's ice maker line and the flexible connectors under sinks and toilets.

Have a look at each one once a year and replace anything bulging, rusty or kinked. Many water heaters from the early building boom are now reaching the 8 to 12 year point where they tend to fail, so check the date on yours.

What's different about water damage in Johnston

Weather

Summer storms can fill the sewers in an hour, and that's when floor drains start to back up. Rivers rise for days after the rain has stopped. Then winter brings a different problem, with frozen pipes that show themselves at the thaw, and ice dams along the roof edge.

Buildings

Most homes have full basements, and many are finished with carpet, drywall and furniture. Poured concrete or block walls can seep under pressure, floor drains can back up during storms, and a failed sump pump can put inches of water on the floor overnight.

Ground

Clay doesn't drain, so after a wet week, water builds up against your basement walls, and it will find the crack. That pressure is known as hydrostatic pressure. If the water comes in along the bottom of the wall, that's usually what you're looking at.

Drying

A basement has no real airflow and hangs on to cool, damp air. So the air has to be pushed. Air movers run low and fast over the floor, and large dehumidifiers keep pulling the water out of the bottom of your walls.

When you call

How a water damage job works in Johnston

First we'll want to know three things: where you are in Johnston, where the water came from and if it's stopped. From there, we'll connect you with a local specialist from our network, so you're speaking to someone who works in Polk County. That goes for homeowners, landlords and businesses alike.

Water travels through walls without leaving a mark, so the first step is measuring, not mopping. A thermal camera and moisture meters map the wet area. Next comes the question of what's in the water. Category 1 is clean supply water. Category 2 has been in contact with something, like a dishwasher overflow. Category 3 is sewage or floodwater, and it calls for containment: plastic sheeting, plus negative air machines with HEPA filters, so nothing spreads through the house.

Getting the water out is the quick part. A truck-mounted or portable extractor handles that. After that, air movers sweep across wet surfaces, and low grain refrigerant (LGR) dehumidifiers take that moisture out of the room. In cold or dense spaces, desiccant dehumidifiers work better. You'll hear the machines day and night for a while, and daily psychrometric readings of the air show that they're working.

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 Johnston home

It depends mostly on how fast drying starts and how dirty the water was. With clean water, carpet can usually stay and the pad goes. Hardwood often comes back with drying mats and patience, and sanding can take care of what's left. Walls may only need a flood cut, which removes the bottom section of drywall, so the rest stays put.

Things change when the water's dirty. Anything soft that sewage or floodwater reached, such as carpet, pad and insulation, gets thrown out. Hard surfaces get cleaned and treated. Have a professional look at any gas appliance that got wet before you turn it back on, and don't walk on a floor that's gone spongy.

Johnston water damage questions

How fast can someone get to me in Johnston?

In most cases you'll have someone on the way that day. You can ask for a time when you're connected with the specialist. It may take longer after a storm, when much of Johnston needs help at once.

Can I clean up water damage myself?

If it's small, clean and caught quickly, go ahead. If it has been sitting, has gone under the floor or smells bad, that's the time to call. The trouble with doing it yourself is that everything can look dry on top and still be wet underneath.

How long does it take to dry out a house?

Plan on several days. Three to five is typical, though a small, fresh leak may be quicker and a large flood may take over a week. The readings decide when it's done, not the calendar.

Can wet hardwood floors and carpet be saved?

It depends on time and on the water. For hardwood, floor drying panels and patience can do a lot, though refinishing may still be needed. For carpet, clean water usually means new pad and the same carpet. Contaminated water means replacing both.

Will my insurance pay for water damage?

It usually depends on where the water came from. A homeowners policy usually covers a burst pipe. Outside flooding needs separate flood insurance, and sewer backup often needs an add-on. It's worth reading your policy, and it's worth having those photos.
