Signs to look for
When to call us for subfloor drying
As moisture readings guide drying, if you notice any of these problems, call us before water has more time to spread into nearby materials.
The screw pattern is telegraphing through vinyl or laminate
From the source check, a swelling panel rises everywhere except where a fastener holds it down.
You can feel a ridge along the seams
Through the final dry check, panels swell at the edges first, which is why edge swell shows up as a raised line under vinyl or laminate.
Tile is loose or grout lines have cracked in a line
Through the final dry check, tile does not move unless the deck under it does.
Laminate or vinyl plank is peaking or lifting
Through the final dry check, floating floors have nowhere to go when the subfloor swells, so they push up at the joints.
A dark line shows on the joists from the basement or crawl space
Through the final dry check, looking up from below is the fastest diagnosis in the house.
What happens
How we handle subfloor drying
Our water-damage technicians adjusts the work to what got wet, how far the water traveled, and which materials can be saved.
Reading the deck before touching the floor
From the source check, a pin moisture meter reaches the decking through a seam, a vent or the carpet edge.
Identifying what your subfloor actually is
To control the wet boundary, plywood, oriented strand board, plank decking and particleboard underlayment all behave differently when wet.
The drying from above or below decision
From the source check, if there is a basement or crawl space under the room, we dry the joist bay from underneath and leave your flooring alone.
Panel and mat systems that pull through the finish floor
From the source check, a floor drying mat or a panel drying system uses gentle vacuum to move air through the assembly.
Minimal access instead of demolition
To control the wet boundary, we prefer a removed threshold, a lifted vent, a closet corner or a small hole in an unfinished ceiling below.
Targeted finish floor removal when it blocks the save
To control the wet boundary, sheet vinyl and glued flooring seal moisture in, so a section may have to come up for the deck to survive.

Why timing matters
What can happen when the area stays wet

A failed panel takes your new floor warranty with it
To control the wet boundary, interior grade panels, decking wetted more than once, and floors walked on hard while saturated are where layers separating actually happens.
Oriented strand board swells and does not come back
Through the final dry check, oSB is chips and resin, so it puffs at the edges and stays puffed.
Fasteners lose their grip and the floor starts talking
As moisture readings guide drying, wet decking softens around every screw and nail, then shrinks as it dries.
New flooring installed over a wet deck fails

Questions about subfloor drying
What is a subfloor and why does it matter?
Through the final dry check, it is the structural panel between your floor joists and your finish flooring.
Why does my floor feel spongy after a leak?

Through the final dry check, most decking dries in place when we reach it within about two to three days.
Do you have to pull up my floor to dry the subfloor?
Through the final dry check, often no. Through the final dry check, where a basement or crawl space is under the room, we dry the joist bay from below and leave your flooring alone.
Is it better to dry from above or below?
Through the final dry check, below is faster and less invasive whenever there is access, because the panel is bare on that side.
How long does subfloor drying take?
From the source check, a closed floor assembly commonly needs four to six days. From the source check, multi layer floors, glued flooring and plank decking can run longer.
How do you know the subfloor is dry?
