ProSeal NSW
Haris personally attends nearly every job — and multiple strata managers now use him across their entire property portfolios.
That's worth knowing upfront: if Haris is across multiple jobs simultaneously, capacity could be a variable to ask about before committing to a timeline. The most practically useful signal for strata owners or body corporate managers is that multiple strata management professionals name ProSeal NSW as their go-to across their portfolios, suggesting the team is familiar with the access, documentation, and approval processes that unit-block work often requires. For a residential homeowner with a leaking balcony or bathroom, the reviews suggest asking for a written scope breakdown — customers mention Haris provides this clearly — so you have something concrete to compare against other quotes.

About ProSeal NSW
Haris — the hands-on lead at ProSeal NSW — specialises in waterproofing and tiling for balconies, bathrooms, patios, and kitchens, with a particular track record on strata and unit balconies that other trades decline to touch. Reviews repeatedly single him out for diagnosing leaks that multiple prior contractors missed, which makes ProSeal worth considering when the problem isn't straightforward. The iCon Remedial Building team that Haris operates alongside handles full bathroom and kitchen fitouts as well as targeted remedial repairs, bridging the gap between a specialist waterproofer and a full renovation crew. Customers most often describe Haris as someone who walks them through exactly what he's doing and why — useful if you're managing a body corporate or strata situation where you need to explain the scope to other stakeholders. Reviews suggest the team works promptly even around wet-weather delays and labour shortages, and several strata managers mention using ProSeal across their portfolio after getting consistent results on first jobs. Pricing feedback leans competitive relative to comparable quotes, with Haris noted for adjusting scope to keep costs manageable without cutting corners on finish.
Best for: strata and unit balcony waterproofing with complex access requirements, diagnosing leaks that previous contractors couldn't identify, and full bathroom or kitchen renovations where waterproofing is part of the broader scope.

What types of waterproofing jobs does ProSeal NSW handle?+
Reviews cover balconies, bathrooms, showers, patios, and kitchens — both targeted leak repairs and full surface replacements involving new waterproofing membranes and tiling. Haris and the iCon Remedial team also take on full bathroom and kitchen fitouts where waterproofing is part of a broader renovation. Several reviews specifically mention jobs on unit balconies within strata buildings, which tend to involve more complex access and approval steps than standalone homes. If your job is a tricky remedial situation that other trades have walked away from, that appears to be a relative strength based on customer accounts.
Does ProSeal NSW work with strata buildings and body corporates?+
Yes — multiple reviewers identify themselves as strata managers who use ProSeal NSW regularly across their property portfolios. One reviewer working in strata management notes receiving 'nothing but great feedback from owners corporations' after bringing Haris in on recommendation. Reviews also mention Haris handling a situation with a building manager smoothly mid-job, which suggests familiarity with the communication requirements of strata work. If you're a building manager or owner in a multi-unit complex, it's worth asking Haris upfront about his experience with your specific building type and any owners corporation approvals you'll need documented.
What do customers say about ProSeal NSW's pricing?+
Pricing feedback in the reviews is generally positive — several customers mention that ProSeal's quotes came in lower than other contractors they approached for the same scope. One reviewer noted Haris 'worked with me to keep costs down and was very flexible compared with competitors,' and another mentioned receiving 'an unmatched price' for a full balcony renovation after multiple other companies had inspected the job. Reviews don't include specific dollar figures, so you'll need to request a quote directly. Based on the sample, asking for an itemised written proposal appears to be standard practice for Haris.
How responsive is ProSeal NSW to quotes and job updates?+
Responsiveness is one of the more consistently mentioned points across the 25 reviews we reviewed — customers describe Haris as 'super responsive' on quotes and 'always available' during jobs. One reviewer highlighted that Haris was 'most helpful and impressively prompt with text responses and documentation follow-up.' A separate review mentions the team completed a job efficiently despite wet-weather delays and labour shortages, suggesting they manage scheduling proactively rather than going quiet when conditions change. Given this is an owner-led operation, it's sensible to confirm availability and lead times before locking in a start date.
Does ProSeal NSW only do waterproofing, or do they handle full renovations?+
ProSeal NSW covers both ends of the spectrum — from targeted waterproofing and leak repairs through to complete bathroom, kitchen, and laundry renovations including tiling, fitout, and finishing. The iCon Remedial Building team that Haris operates with has handled multi-room renovation projects, and at least one reviewer returned for a second renovation (kitchen and laundry) after a successful bathroom fitout. Reviews suggest Haris also makes design input where it improves the outcome — one customer noted he 'made a few suggestions to my plan' that improved the ergonomics of the fitout. If you're combining waterproofing with a broader reno, that appears to be within their scope.
