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.
