Experienced Waterproofers for Ashbury Homes, NSW 2193

Looking for waterproofing in Ashbury? We are experts in providing reliable waterproofing services in Ashbury for family homes, renovations and small unit blocks. As licensed Ashbury waterproofers, we fix leaking bathrooms, laundries and damp brickwork using membranes suited to older homes – with a free inspection and a written 7-year warranty.

Ashbury is one of the inner west’s best-preserved residential suburbs, with much of it inside a heritage conservation area. Streets of Federation cottages and inter-war Californian bungalows sit on solid brick foundations, many with original bathrooms and laundries tucked into rear extensions added decades ago.

These homes weren’t built with modern wet-area membranes, and their brick walls can draw moisture up from the ground. When owners renovate, the waterproofing needs to be done properly the first time. We look at how each house was built and choose a system that protects the original structure as well as the new tiles.

Waterproofing Services for Ashbury’s Character Homes

Every waterproofing service is available in Ashbury. We give the most attention to bathrooms, laundries and damp brick walls – the areas where the suburb’s older homes are most likely to let water in.

Bathroom & Shower Waterproofing Ashbury

Ashbury renovations often uncover bathrooms with no membrane at all, or one that has failed after decades of use. We waterproof new bathrooms to AS 3740 and repair leaking showers before water rots the timber floor and joists underneath.

  • Full bathroom and shower recess membranes
  • Compliance certificate for your renovation
  • Leak repairs in existing bathrooms

Damp brick wall treated and sealed against moisture Heritage brick

Brick Wall & Damp Waterproofing

Federation and inter-war brick homes can suffer from rising and penetrating damp, which shows as flaking paint, salt deposits and musty rooms. We treat and seal brick walls, parapets and chimneys so moisture stays out of the masonry.

  • Rising and penetrating damp treatment
  • Parapet, chimney and external wall sealing
  • Solutions suited to older brickwork

Laundry Waterproofing Ashbury

Laundries in Ashbury are often squeezed into older rear additions with timber or uneven slab floors. We waterproof the floor, tub area and wall junctions so a leaking machine or overflowing tub doesn’t damage the rest of the house.

  • Laundry floor and upturn membranes
  • Sealed wall and floor junctions
  • Ideal during kitchen and laundry renovations

Outdoor terrace waterproofing membrane Verandahs & decks

Verandah, Terrace & Courtyard Waterproofing

Tiled front verandahs, rear decks and courtyard terraces over rooms or garages need an external membrane that handles sun and storms. We re-waterproof them so water drains away instead of seeping into walls and ceilings.

  • Tiled verandahs and rear terraces
  • External membranes to AS 4654
  • Careful detailing at doors and edges

Know the Warning Signs

Signs Your Ashbury Home Needs Waterproofing

Older homes give early warnings before water damage gets serious. If you notice any of these around your Ashbury home, call us for a free inspection.

  • Damp, peeling paint low on walls

    Rising or penetrating damp is getting into the masonry.

  • Mould, musty smells or black grout

    Water is sitting behind tiles or inside the wall cavity.

  • White salt on brick or concrete

    Efflorescence means water is moving through the masonry.

  • Loose, drummy or cracked tiles

    The bond has failed because the bed underneath is wet.

  • Swollen skirting or door frames

    Water is wicking out of a wet area into the timber next to it.

  • Stains on the ceiling below

    A bathroom, balcony or roof above is leaking through the slab.
