Get Waterproofing QuotesWhat Affects the Quote
- Terrace build-up. Tiles, screed and membrane removal add cost before new waterproofing.
- Penetrations. Solar mounts, balustrades and pipes need careful detailing.
- Occupancy. Working around tenants may mean extra visits.
- System choice. Polyurethane under tiles costs more than acrylic on an exposed roof.
Where Terraces Usually Leak
- At the door threshold where the membrane stops short.
- At balustrade fixings drilled through the membrane.
- At outlets that sit higher than the tiles.
- At cracked grout and failed perimeter sealant.
Questions to Ask
- Will you test the leak before quoting a full redo?
- How will you detail the threshold and balustrade fixings?
- Which products resist salt air and UV?
- How long before the terrace can be used?
- Is the guarantee for workmanship, product or both?
Waterproofing Big Bay FAQs
My ceiling leaks only when it rains hard. Is it the terrace or the roof?
It could be either, or a window above. A contractor can flood-test the terrace to rule it in or out.
Can work be done while the unit is let?
Often yes for roofs and walls. Terrace and shower work usually means the area is out of use for a few days.
Is polyurethane better than torch-on for a terrace?
Under tiles, liquid membranes are common because they follow details closely. The right choice depends on the build-up and inspection.
How often should coastal waterproofing be checked?
Once a year, ideally before winter, so sealants and coatings can be touched up early.
Will the leak be fixed in one visit?
Small repairs can be. Full terrace waterproofing usually takes several days plus curing time.
