Why does my basement only get wet after heavy rain?
Because the clay soil around Montgomery County foundations holds water instead of draining it. After a hard storm, that water sits against your walls and floor and pushes its way in at the weakest point — usually the joint where the wall meets the floor. It isn't a hole to plug; it's pressure to relieve, which is what a perimeter drain does.
Does the inspection really cost nothing?
Nothing. Dean comes out, looks at what the water is doing, explains it, and gives you a price. If it turns out to be something minor — a grading fix, a downspout — he'll tell you that instead.
What is a french drain, in plain English?
A channel along the inside perimeter of the basement, down at the footing, filled with stone and a sloped pipe. Water that used to push up through your floor edge falls into the channel instead and runs to a sump pit, where a pump sends it out and away from the house.
My house is old — stone foundation. Can that be waterproofed?
Yes. Ambler's older homes weep through stone and mortar rather than cracking like block, and the approach is different — but one of Dean's customers wrote that his '80 year old basement is dry' after a full perimeter system. Old houses are normal work here, not a special case.
What happens if the power goes out in a storm?
That's exactly when you need the sump most, which is why Dean installs backup systems. One customer's backup ran for a day and a half through a winter power cut and the finished basement stayed dry.
Do you do small jobs, or only full systems?
Both. Some basements need a full perimeter drain; some need a crack sealed or a drain added around a water heater. One review describes exactly that — a small drain by the water heater that saved the finished basement when the heater failed years later.
How fast can the work be done?
Most jobs are done quickly once scheduled — reviews mention crews that 'flew through the grunt work' and left no mess. Dean will give you a realistic timeline when he sees the job.
Do you fix work another company did badly?
Yes. Dean has taken over jobs mid-stream after homeowners fired another waterproofer, and made the system right. If you're stuck partway through a bad job, call — it's not the first time.
