Overview
About subfloor drying
The subfloor is the plywood, OSB, or concrete beneath finished flooring. Water that seeps through seams and edges collects there and stays long after the surface looks dry.
Subfloor drying may involve lifting flooring, drying from below in a crawl space or basement, or using specialized drying systems that work through the floor.
Subfloor Drying is part of our damage by building area. How we handle the specific materials and spaces water reaches.
- Measure moisture below the finish floor
- Remove or vent flooring where necessary

How it works
From first call to fully restored
The water damage process we follow on every job, step by step.
Call Now (833) 502-4258- 1
Emergency contact and source control
We help you shut off the water source and electricity to affected areas when it is safe to do so, and ask the questions that tell us what equipment to bring.
- 2
Inspection and water classification
Technicians identify where the water came from (clean supply, gray water, or contaminated black water) because that changes what can be dried and what must be removed.
- 3
Extraction
Truck-mounted or portable extractors remove standing water from floors, carpet, and pad. Extraction removes far more water than air movement alone can.
- 4
Moisture mapping
Moisture meters and thermal cameras trace water inside walls, ceilings, and subfloors so drying targets the real wet area, not just the visible stain.
- 5
Structural drying
Air movers and dehumidifiers are placed for the room's size and materials. Readings are taken daily until materials return to normal dry levels.
- 6
Repair and documentation
Unsalvageable materials are removed and replaced. Photos, readings, and drying logs support your insurance claim.
Water Damage essentials
The three categories of water
Restoration standards sort water losses by contamination level. The category decides how we clean, what we can save, and whether the job needs biohazard procedures.
Call Now (833) 502-4258Category 1: Clean water
Supply lines, broken pipes, and overflowing sinks with clean water. Most materials can be dried in place if work starts quickly.
Category 2: Gray water
Washing machine and dishwasher discharge, or some toilet overflows. It carries contaminants, so porous items often need cleaning or removal.
Category 3: Black water
Sewage, rising floodwater, and water that has sat long enough to grow bacteria. Porous materials it touches are usually removed and the area is sanitized.
Right now
What to do in the first hour
These steps limit the damage and keep everyone safe until our team arrives.
Call Now (833) 502-4258Stop the water
Close the fixture valve or the main shut-off, usually near the water meter, the water heater, or where the main line enters the house.
Make it safe
If water is near outlets or the electrical panel, do not touch anything electrical while standing in water. Turn off power only from a dry spot.
Protect what you can
Move rugs, electronics, documents, and furniture to a dry area. Put foil or blocks under furniture legs that must stay.
Document it
Take photos and video of the water and damaged items before cleanup starts. Your insurer will want them.
Call your insurer and us
Report the loss and call for extraction. Do not wait to see if it dries on its own.
What to expect
How long water damage restoration takes
Every job is different. This is the typical sequence and what drives the schedule.
Call Now (833) 502-4258Day 1
Emergency response, inspection, extraction, and drying equipment set up.
Days 2 to 4
Daily moisture readings and equipment adjustments until materials reach dry standard.
Day 3 to 5
Drying verified, equipment removed, and a repair scope prepared.
Following weeks
Repairs such as drywall, flooring, and paint, depending on materials and approvals.
Many homeowners policies cover sudden and accidental water damage, such as a burst pipe or a failed supply line. Gradual leaks, poor maintenance, and outside flooding are commonly excluded. Flood damage usually requires a separate flood policy.
We photograph the damage, record moisture readings every day, and keep drying logs. That documentation helps your adjuster see what happened and why each step was needed.
When you authorize it, we can talk with your adjuster directly so you do not have to relay technical details.
- Do not walk into rooms with standing water if outlets, cords, or appliances are submerged. Shut power off at the breaker only if you can reach it while standing somewhere dry.
- Sagging ceilings can hold a lot of water and may collapse. Stay out from under them.
- Water from toilets, sewers, or outside flooding can carry bacteria. Avoid skin contact and keep children and pets away.

Call now: (833) 502-4258Will my insurance cover it?
Many homeowners policies cover sudden and accidental water damage, such as a burst pipe or a failed supply line. Gradual leaks, poor maintenance, and outside flooding are commonly excluded. Flood damage usually requires a separate flood policy.
Call now: (833) 502-4258How long does it take to dry a house after water damage?
Most structural drying takes three to five days once extraction is done. Dense materials like hardwood, plaster, and concrete can take longer. We judge it by moisture readings, not by the calendar.
Call now: (833) 502-4258Does homeowners insurance cover water damage?
Many policies cover sudden and accidental water damage, such as a burst pipe, but often exclude gradual leaks and outside flooding, which usually needs separate flood insurance. Your policy wording decides it. We document the loss so you can file accurately.
Call now: (833) 502-4258Can I dry it myself with fans?
Fans dry surfaces, but water trapped inside walls, under flooring, and in insulation usually needs extraction, dehumidification, and moisture readings to confirm it is truly dry. Trapped moisture is a common cause of later mold growth.
Call now: (833) 502-4258Do you remove the carpet?
Not always. Carpet wet with clean water can often be dried in place. The pad is frequently replaced, and carpet soaked by contaminated water is usually removed.
