Coastwide Waterproofing
A rare combination of retail supplies and hands-on waterproofing work, with named staff customers keep coming back to for advice.
The dual shop-and-service model is mentioned by several reviewers and suggests this isn't a fly-by-night operation — they have a physical presence in Gosford that you can walk into to get advice before committing to any work. That said, 13 reviews is a thin track record to draw firm conclusions from, so it's worth asking directly about the specific scope of your job — whether waterproofing installation, surface treatments, or materials supply — to confirm they're set up to handle it.

About Coastwide Waterproofing
Coastwide Waterproofing operates as both a trade services business and a retail supply shop, which means you can come in to buy tiling and waterproofing products yourself or have their crew handle the job for you — a genuinely uncommon combination in the Gosford area. Craig, Regan, and Yanna are specifically named in reviews for their contributions, with Craig appearing to lead on client communication and technical guidance, while the broader team draws consistent praise for knowing their products in depth. Gianni also gets a mention as a friendly, approachable face who's ready to give practical advice on the spot. The shop angle matters: customers describe it as a go-to source for tiling and waterproofing supplies, suggesting they stock the kind of trade-grade materials that DIYers and contractors actually want. Their Google categories also include painter, pointing to a broader range of surface preparation and treatment work beyond waterproofing alone. If you're working on a bathroom renovation, a wet area, or any surface that needs sealing and tiling, this is a place where you can get expert advice and materials in one stop — not just a tradie who shows up and quotes.
Best for: homeowners wanting expert waterproofing advice before committing to a job, bathroom or wet area waterproofing projects on the Central Coast, and tradies or DIYers sourcing quality tiling and waterproofing supplies locally.

Does Coastwide Waterproofing have a physical shop I can visit?+
Yes — multiple reviewers specifically mention visiting the shop in the Gosford area to browse tiling and waterproofing products and get advice in person. This makes them unusual compared to most waterproofing tradies who only do on-site quotes. If you want to look at products or talk through your options before committing, dropping into the shop is a genuine option. Call ahead to confirm current trading hours before making the trip.
Who are the key people I'd be dealing with at Coastwide Waterproofing?+
Reviews name Craig, Regan, Yanna, and Gianni as team members customers have interacted with directly. Craig and Regan appear in a review praising the quality of work and customer effort, while Gianni is called out as professional, friendly, and quick to give advice. The owner is also specifically commended for knowing their products in depth. It reads like a small, stable team rather than a large rotating workforce.
Can Coastwide Waterproofing supply materials for a DIY job, or do they only do trade work?+
Both, based on what customers describe. Several reviewers mention buying tiling and waterproofing supplies from the shop for their own projects, while others reference completed work by the crew. Reviewers describe the staff as genuinely helpful with advice on which products to use, so even if you're planning to do the job yourself, they appear willing to steer you in the right direction. Confirm what you need when you call or visit.
What do customers say about pricing at Coastwide Waterproofing?+
At least one reviewer specifically mentions 'affordable prices' alongside quality finishes, which is a useful data point — though with only 13 reviews total, it's hard to draw broad conclusions about where they sit on price compared to competitors. No reviewers raise concerns about cost overruns or unexpected charges. For your specific job, it's worth getting a written quote so you can compare directly.
What areas does Coastwide Waterproofing service?+
The business is based in West Gosford on the Central Coast of NSW, and reviews reference customers from the broader Gosford area. Their Google profile doesn't specify a formal service radius, and the reviews don't mention travel to other regions. If you're outside the immediate Gosford area, it's worth calling to confirm whether they'll travel to your location and whether there's a call-out fee involved.
