"Tyrell did an excellent job correcting the mistakeS of the people who installed my basement waterproofing equipment. There was a terrible rotten egg smell and that's gone now. Tyrell cleaned up after himself, if any water spilled he made sure to vacuum it up and to dispose of everything in the proper place."

"This company customer service skills and communication are horrid. I had no problem scheduling an appt for someone to sell me on their business but they day the work was to be done, I had to call them 5x for ETA checks on their techs. They were supposed to arrive between 9-9:30am and did not arrive until 1:15pm. Each time I called about the tech ETA, I was told by the receptionist that they would check and call me right back, they never did. The 5th time the receptionist said the supervisor of the techs said they were dispatched to my location early that morning, but he does not know where they are or why they did not show up. The receptionist called back later to say the techs should arrive by 12pm but they did not arrive until 1:15pm. When the techs arrived, I found that their supervisor told them to do a job prior to coming to my location. I was supposed to receive a lifetime warranty for the work done and after 4 calls I still have not received it. Poor customer service."

Basement Waterproofing questions, answered by experts

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.
