Auckland Waterproofing Experts is a local LBP team helping homeowners and builders keep decks, flat roofs, basements, and garages dry. We focus on careful prep, clean sites, and membranes that suit Auckland’s weather — not a paint-over-damp quick fix.
Waterproofing Auckland basements on the North Shore
Damp basements and below-ground rooms are a common North Shore problem. We specialise in internal tanking and negative-side systems when external dig-outs are impractical, including garage floors and walls. Work is planned after a site visit so the system matches the substrate and moisture source.
Garage and retaining-wall tanking
Seeping block walls, musty garages, and retaining walls need the right membrane and prep — grinding, repair, then a proper waterproofing system. We install Council-ready work with PS3 where required, and we coordinate clearly so you know what happens on each visit.
Deck and roof membranes across Auckland
We also install and replace membranes on decks and low-pitch roofs using proven systems (including torch-on, TPO, and liquid options where they fit the job). We do not replace timber decks or metal roofs as a carpentry or roofing company — we waterproof them when a membrane is the right answer.
Based in Castor Bay, we work Auckland-wide with densest coverage on the North Shore. Every job is quoted after we see the site. Call 022 630 6434 or email aucklandwaterproofing@gmail.com to book a visit.
Hi Hired Alex to provide waterproofing solutions for my rear retaining cinder block wall. In older 1970s homes they never used to waterproof these walls and it was seeping through and making the rear musty and damp. Alex ground the paint off and applied fibre glass reinforced waterproofing and filled in parts of the wall that were hollow with a special cement and now the room is all dry and actually pleasant to be in. Thank you Alex job well done.
Alex is great to deal with. Very knowlegable and takes pride in his work, making sure he was happy with the waterproofing job before we closed the walls all back up. Great communicator and friendly guy. Will definitely use Alex again
Using this company for my basement waterproofing was a brilliant decision. Alex was prompt, communicative, skilled and professional. His work was immaculate and he explained the process fully and made helpful suggestions for ongoing care. Alex has a calm, friendly, assuring manner and he was a pleasure to have working on my property. In fact he made the job fun! I would not hesitate to recommend Auckland Waterproofing Experts.
Hustle free, came to give a quote the same day I called them, price was negotiable, job got done in 1 day only working over time, passed the council inspection in 5 minutes. Highly recommend
Great communication, got back to me straightaway, was an unplanned job so needed a quick response. They came in and did a great job, clean tidy and very professional. Fully recommended
Shout out to Auckland Waterproofing Experts for the outstanding job. The team was professional, fast, and very thorough. They quickly identified the issue, explained everything clearly, and delivered high-quality waterproofing that solved the problem.
