Leak Repair

We stop the leak at the point where water gets in.

Lift-pit waterproofing, roof waterproofing, exterior wall repair and leak repair. On-site checks and quotes are free.

When to come to us

  • Water collects in the elevator pit

  • Rain gets in from the roof or balcony

  • Cracks in the exterior wall concern you

  • It was repaired before, and it is leaking again

Why it comes back after being repaired

Where the water shows and where it gets in are usually two different places. Seal only the visible exit and the water simply finds the next weak point. We first identify the entry point and the path, then build the repair around stopping it.

Safety first — protecting people, buildings and business.

Common symptoms, and where we look

Here is where we look first for each symptom. We start from the entry point, not the exit.

  • A stain spreading on the ceiling

    Not necessarily directly above. Water travels sideways along pipes and beams

  • Wet only after rain

    We suspect wall cracks, split sealant, or joints in the coping

  • Only during the thaw

    We suspect gaps opened by freezing, and water pooling on the roof

  • Damp all year round

    We suspect the basement walls, pipe penetrations, or a rising and falling water table

What we look at on site

Besides where the water enters and the path it takes, if a previous repair failed to stop it, we look there again. Once the cause is clear we set out the method and scope with the reasons for them, and report in a form you can keep — usable when explaining things to residents or owners.
