Waterproofing in Seven Hills
Seven Hills is our home base, not a pin we drop on a map for SEO. Sydney Waterproofing Services operates from Factory 29, 6 Abbott Road, Seven Hills NSW 2147. When you call about a leak in Seven Hills, Toongabbie, Winston Hills edge, or the industrial and warehouse pocket around Abbott Road, we’re already in the area.

Housing and building mix here
Seven Hills sits between older post-war housing, brick veneer renovations, townhouse rows, and light industrial / commercial stock. That mix shows up in the jobs:
- Family bathrooms in 1960s–80s houses where the shower has been “updated” with new tiles over an old or incomplete membrane. Water marks on the ceiling below, soft skirting, or a musty cavity usually mean the wet area needs proper rebuild to current AS 3740 practice — not another coat of paint on the stain.
- Ground-floor outdoor rooms and rear balconies on raised homes where the door threshold sits close to the finished floor level. Poor falls and failed junctions at the door are a regular water path into living rooms.
- Planter boxes against garage or boundary walls — overflow and failed planter membranes staining brickwork and tracking into garages.
- Factory and warehouse wet areas / rooftops on the Abbott Road and nearby industrial strips — sheet and torch-on systems, roof outlets, and plant-area detailing.
We’re not chasing every suburb with the same paragraph. Seven Hills jobs are often short travel, which keeps mobilisation simple for smaller remedial scopes as well as full bathroom or balcony strip-outs.
Typical work from the Seven Hills workshop
- Bathroom waterproofing and shower recesses
- Balcony waterproofing including falls and drain detailing
- Remedial waterproofing when the leak source isn’t obvious from photos alone
- Rooftop waterproofing on houses and low-rise commercial
- Kitchen and laundry wet areas, caulking, tiling where it forms part of the waterproofing scope
- Torch-on and sheet membranes where the substrate and use call for them
- Strata waterproofing for local blocks and townhouse schemes
- Commercial waterproofing for workshops, offices, and multi-unit sites
No basement service page — we don’t market basement waterproofing as a core offer.
What local owners usually ask first
“Can you look this week?” Often yes for inspections in Seven Hills and immediate surrounds, subject to the schedule. Call 1300 949 191 with the address and a short description (e.g. shower leaking into void, balcony staining soffit below, rooftop ponding at outlet).
“Do I need a certificate?” For bathroom and wet-area work, builders, certifiers, and sometimes buyers or strata managers will ask for compliance paperwork from the licensed waterproofer. Read our NSW waterproofing certificate guide — practical overview, not legal advice — then ask us to include certificate and photo records in the scope.
“What’s it likely to cost?” Depends on strip-out, substrate repair, membrane system, and finishes. Ballpark Sydney figures are in the 2026 cost guide. Treat those as indicative only; Seven Hills jobs still need a site quote.
