Storm Intrusion

Storm Water Intrusion: what it covers

Quick answer

Storm water intrusion is rain or runoff that enters a house through doors, vents, window wells, garage openings or gaps at the foundation. In Chico, calls are answered 24/7, a crew extracts the water, traces the entry points and dries the structure to a set standard.

Storm water rarely comes in as a flood. It arrives as a trickle at a door sill, a seam in the garage floor, a vent on the low side or a window well with a cracked cover. Each opening lets in a little, and a long storm can add up to a lot. The water spreads along the lowest flooring and into the cavities behind the baseboards before anyone notices.

Storms can arrive as heavy bursts or as long soaking periods, and the water a house takes in depends on both. The Five-Mile Basin and the creek system describe the big picture for the city, but the water that comes through a particular door is decided by the grade, the seals and the openings in that house. A crew reads those on site.

If storm water is coming in now, move people and pets to a dry room, keep clear of any outlet or appliance in the water, and call (833) 490-5225. Calls are answered 24/7, and a crew is sent as fast as one is available. No arrival time is promised for any call.

How does storm water get past a closed door?

Storm water gets past a closed door through the gap under the door, a worn seal or a low threshold, and it is pushed by the wind and by standing water outside. Once inside, it runs along the lowest flooring and can reach the cavity behind the base molding.

A door seal wears over time, and the gap at the bottom of a door can admit a steady flow when water stands against the threshold. A garage door seal works the same way, and the wind can drive water under it. The gap is often hard to see from inside the house.

Once through the gap, the water follows the floor. It runs under the first few feet of flooring and wicks up the lower wall, so the damage is often larger than the puddle near the door.

Why do vents and window wells let water in?

Vents and window wells sit at or near grade, where water pools after a storm. A cracked cover, a clogged drain or a vent with no screen lets the pooled water in, and the crawl space or lower room takes it first.

A window well is a small pit beside the foundation. When it fills with leaves and soil, the drain stops working and the water rises until it finds the window or the vent. The same is true of a vent opening that sits lower than the ground outside.

The crew clears the opening and checks the space behind it. The lower room or crawl space often holds more water than the visible area suggests, so the readings extend beyond the window.

What should a homeowner check after a storm?

Check the thresholds, the garage door seal, the window wells and the vents on the storm side, and look for damp spots, silt and staining. Report any water you find to the crew while the evidence is fresh.

Walk the outside of the house and the inside of the lower rooms after a storm. Look for silt at the thresholds, damp carpet at the entry, and staining at the base of the walls. Note the time you first saw the water.

Keep the damaged materials and the photographs until the insurer has seen them. A record of the storm, the entry and the damage is the most useful thing a homeowner can keep.

What moves the price of storm water intrusion work?

Price moves with the number of entry points, the area of floor and wall the water reached, how far it wicked and how long the drying must run. The price is explained and approved on site before any work begins.

The number of entry points matters because each one is checked and read. The area of floor and wall the water reached is the second factor, and the height it wicked up the wall is the third. The length of the drying, which follows from those, completes the picture.

No figure is given on this page. The crew explains each factor for your house and states the scope and the price before work starts. Sealing the entry is a separate job, and the crew says so when it applies.

How can a homeowner reduce storm water entry?

Keep thresholds clear, replace worn door and garage seals, keep window wells and vents free of debris and check that water drains away from the house. Grading and sealing work belongs to a contractor, and the crew can describe where water entered.

Clear the threshold and the window well before each wet season, and replace a seal that no longer touches the door. Make sure the gutters and downspouts direct water away from the foundation, since water running along the wall finds the openings.

For grading, sealing or a new threshold, ask a contractor who does that work. The restoration crew's report of where water entered is useful information to bring to that conversation.

Warning signs

Signs you need storm water intrusion

Do not step into standing storm water near outlets, a panel or a running appliance, and do not run a generator or a pump indoors. Keep children and pets out of the water until the power is confirmed off. Wash exposed skin and clothing after contact with storm water and silt, since it can carry debris and unknown material.

  • Water or damp silt at a door sill, a garage threshold or a sliding door track after rain
  • Damp carpet or flooring near an exterior door or the garage entry
  • Staining at the base of the wall on the side of the house that faces the storm
  • Dampness in a window well or a vent opening that has been wet for some time
  • Baseboards that swell or lift at the lowest point of the room
  • A musty smell in the lower rooms that returns after each storm
Our process

How our storm water intrusion visit works

  1. Clear the threshold and the path

    The technician checks the entry first, clearing debris from the threshold, the garage door seal or the window well so water can drain away from the opening. The power to any wet area is confirmed off before the crew works near it.

  2. Extract the standing water

    Water on the floor is pumped or vacuumed out, starting nearest the entry and working inward. Starting at the entry stops the water from spreading into rooms that were dry.

  3. Find every entry point

    Each door, vent, seal and gap on the affected side is checked. The crew reads the wall and floor at each point with a moisture meter, because a small opening can wet a large area behind the baseboard.

  4. Open the base of the wall where needed

    Baseboards and the lower drywall are removed where the readings show moisture, so the cavity can dry from the inside. The cuts are kept low, close to the water line, to keep the job to what the water reached.

  5. Dry and record the readings

    Air movers and dehumidifiers run until the floor and wall reach the dry target in the scope. The moisture log records the readings, and the homeowner receives it at the end of the job.

Options

Types and options for storm water intrusion

Water through a door or a garage door

Water that enters at a door or under a garage door usually spreads across the floor and under the first few feet of flooring. The crew checks the seal, the threshold and the frame, and it dries the flooring and the lower wall in the entry area before anything else.

Water through a vent or a window well

Vents and window wells at grade can take in runoff that pools against them. The water often reaches the framing or the crawl space first, and it may show in a room only after a while. The crew clears the opening and reads the area beneath it.

Water through a gap at the foundation or a slab edge

A gap at the foundation or along the slab edge can let a steady trickle in during a long storm. The crew describes the gap and the pattern of the staining, and it dries the materials the trickle reached. Sealing the gap is separate work for a builder or a contractor.

Storm water comes in under a side door during a long rain

What homeowners notice
During a long storm, water runs down the hillside toward a side door. By morning there is damp carpet inside the threshold and a silt line along the door sill.
What we do
The crew clears the debris from the threshold and the drain path outside, extracts the water inside and reads the floor and wall base near the door. Baseboard is removed where the readings show moisture, and air movers and a dehumidifier are set in the entry room.
What to expect
The log shows the entry room reached its dry target, and the homeowner was advised to replace the door seal and clear the drainage at the threshold. The silt line and the readings were kept for the insurer.

Butte County

Why storm water intrusion is different in Northern Sacramento Valley, California

A storm can run hard for a short period or soak the ground for a longer one, so water can reach a house in more than one way during the same event. The crew checks the door side, the vent side and the garage side, because each one can take in water at a different point in the event.

The Park Fire began in Bidwell Park on July 24, 2024. Storm water that runs off burned ground carries more silt, and silt can clog a window well drain or a vent screen faster than clean water would. A crew that finds silt at an entry records it, because it shows where the water came from and how it arrived.

The County's flow estimates describe the Five-Mile diversion at the system scale. A storm that enters a house through a door sill is a house-scale event, and the crew reads it on the house, including the door, the seal and the grade at that door.

FAQ

Storm Water Intrusion FAQs

Is storm water in the house a true emergency?

It can be, if it reaches outlets, appliances or a furnace, or if it keeps coming in. Call (833) 490-5225 while it is still happening. Calls are answered 24/7 and a crew is sent as fast as one is available.

Why is there water in my room when the rain stopped?

Water that entered during the storm can keep running along the floor or soak into the cavity after the rain has stopped. The crew reads the wet area as it is, not as it was during the storm.

Can the crew stop the water from coming in?

The crew can clear debris from an entry and extract water that is already inside. Sealing a gap, replacing a seal or changing the grade is separate work, and the crew can tell you where the entry is.

How long will the drying take?

It runs until the readings reach the dry target in the scope. Water that wicked into the wall or under flooring takes longer than water on the surface. No finish date is promised on any call.

Will my insurer pay for storm water in the house?

The policy and the insurer decide what is covered, and coverage can depend on how the water entered. Keep the photographs, the readings and the crew's written scope, and let the insurer review them before materials are removed.

Should I remove the carpet myself?

Carpet that has soaked storm water is often removed because it holds silt and moisture. Photograph it first and let the insurer see it if you can. The crew explains which materials it recommends removing and why.
