Why Markham Calls Us for Wet Basements
Below-grade spaces trap moisture, and basement water doesn't drain off on its own. You're drying against concrete that holds water, which takes the right equipment.
Pumps & Basement-Ready Equipment
Contractors bring submersible pumps, truck-mount extractors, and LGR dehumidifiers sized for below-grade drying. Slab and foundation walls need sustained dehumidification.

Basement Work Through Our Network
Here's what basement cleanup typically includes.
Basement Water Pumping
Pumps remove standing water and discharge it far enough from the house to avoid recirculating. Extraction handles the last thin layer.
Carpet, Pad & Drywall Removal
Carpet pad on a slab rarely dries well and is usually removed. Wet drywall is cut out above the waterline along with soaked insulation.
Sump Pump Inspection
They'll look at the float, check valve, discharge line, and power supply. Many homeowners add a battery backup or second pump after a flood.
Seepage & Window Well Issues
Hydrostatic pressure can push water through cracks, the wall-floor joint, or window wells. White, chalky efflorescence on walls shows where moisture has been moving.
Slab & Foundation Wall Drying
Concrete holds water deep in the slab, so dehumidifiers often run longer than in upstairs rooms. Readings confirm the space is dry before any rebuild.

Basement Cleanup Stories From Markham
Each of these began with a wet basement and a sinking feeling.
The sump float jammed in a storm and the basement filled with about four inches. They pumped it out, pulled the carpet and the bottom two feet of drywall, and had dehumidifiers running that night.

— Doug E., MarkhamAfter the cleanup we added a battery backup sump on their suggestion. It's already saved us once during a power outage.

Why did my basement flood?
The most common causes are a failed or overwhelmed sump pump, heavy rain raising groundwater, clogged gutters or downspouts dumping water near the foundation, flooded window wells, and plumbing or water heater leaks.
Is it safe to go into a flooded basement?
Avoid it if anything electrical is wet or submerged. If you smell gas from the furnace or water heater, leave and call the utility.
Can basement carpet be saved?
Sometimes, if the water was clean and it's extracted quickly. The pad underneath usually needs replacement because it holds water against the slab. Carpet soaked by groundwater or sewage is generally discarded.
How long does it take to dry a flooded basement?
Usually three to seven days. Concrete slabs and block walls hold moisture longer than wood-framed rooms, so dehumidifiers may run longer than upstairs drying would.
How can I keep my basement from flooding again?
Extend downspouts, test the sump each season, add a backup pump, cover window wells, and seal or repair cracks in the foundation.
