WHERE MOST WAREHOUSE LEAKS BEGIN

A box gutter sits inside the roof, not on the edge of it. That's what makes it good at catching water, and good at causing trouble. When it blocks, rusts or can't keep up with a downpour, the overflow doesn't spill harmlessly over the side. It runs back under the sheets and into the building.
We walk the full length of the gutter, check every joint, sump and outlet, and look at whether the overflows can actually cope with a Melbourne storm. Then we tell you whether it needs a repair or a replacement.
If it's already rained inside, we can fix that too. Our water damage and mould team handles the ceilings, walls and floors. And to stop it happening again, we can clear your gutters on a regular schedule.
