Frequently Asked Questions

We deliver end-to-end property solutions including facilities services coordination, building washing and exterior cleaning, building and property maintenance, projects and construction, specialist waterproofing, metal roofing, and rope-access (abseil) maintenance - so you can reduce supplier complexity across your portfolio.

We work with commercial and industrial landlords, body corporates, building owners, building managers and facility teams. The only residential work we take on sits inside our Gunac waterproofing division - specialist membrane work on high-end homes - and is covered in the waterproofing FAQ below.

Yes. We can structure delivery across multiple assets with integrated planning, scheduled programmes, and a single point of coordination - helping you maximise efficiencies and reduce avoidable cost.

We have offices in Auckland, Tauranga and Hamilton, and we can service properties nationwide. To do this effectively, we'll discuss commercial volume, demand clustering and future potential, especially for remote areas, so we can plan resourcing and delivery reliably.

Yes. We can coordinate multiple workstreams so you deal with one partner rather than managing multiple contractors.

Yes. We plan and schedule work with you to reduce disruption - considering access constraints, operating hours, stakeholder communications and safety requirements for occupied sites.

Yes. Where practical, we bundle tasks and coordinate the right trade/technician to reduce callouts, admin, and disruption.

To quote accurately, we typically need the site address, scope of work, access constraints (e.g., height/roof access), preferred timing, and any known issues such as leaks or surface deterioration. For larger portfolios or nationwide delivery, we'll also discuss volume, geographic clustering and forecasted demand.

We provide commercial exterior cleaning services including building washing, water blasting, window cleaning, roof washing, gutter cleaning/clearing, car park water blasting, internal warehouse cleans, and condition reporting/inspections.

They're different approaches. Pressure washing uses higher pressure for robust surfaces (e.g., paving/concrete), while building washing typically uses low-pressure/soft-wash methods for more delicate exterior finishes. We select the safest method for your materials and contamination type.

Yes. We use a mix of access methods including rope access (abseiling) and elevated work platforms (e.g., cherry picker trucks) to reach challenging areas safely and efficiently.

Yes. Our rope-access teams can assist with a range of at-height maintenance activities (where appropriate) such as visual inspections and selected façade works like painting and glazing/sealant repairs.

Yes. We can provide building condition feedback (including photo-based reporting where appropriate) to help you plan preventative maintenance, renewals and budgets with confidence.

Regular exterior washing helps manage grime and contaminants that can contribute to deterioration. It also supports presentation, helps protect building materials, and can assist with meeting upkeep expectations for warranties and insurers where cleaning is required.

Yes. We can set up recurring programmes and coordinate timing with your site requirements to minimise disruption to tenants, customers, and operations.

For building washing, we operate with in-house capability and do not subcontract this work, which helps us maintain control over safety, quality and delivery. In certain circumstances we will use approved subcontractors that have been through a stringent subcontract management selection process.

Yes. We can deliver planned, preventative maintenance programmes and reactive maintenance support - helping you address minor issues early and reduce the impact of unplanned failures.

Yes. We provide reactive maintenance support alongside planned programmes - helping you resolve urgent issues while also reducing future unplanned failures through preventative planning.

Yes. Our maintenance capability includes multi-trade delivery, including general maintenance and repairs and access to certified trades such as plumbers and electricians - so many day-to-day issues can be handled through a single service partner.

We coordinate maintenance through a central workflow that triages requests and assigns the right trade/technician, improving response times and communication across stakeholders.

Planned maintenance helps identify issues early, reduces emergency callouts, supports compliance planning, and protects asset condition - often lowering whole-of-life cost.

Yes. We can support projects from scoping and budgeting through trade coordination and delivery, including commercial refurbishments and fitouts, roofing and cladding-related works, and other building projects.

Yes. For project work, we can coordinate trades and manage delivery in a structured way, including navigating typical consent and inspection requirements where they apply.

Yes. We undertake metal roof repairs, maintenance and replacements, including related components such as gutters/spouting, flashings and downpipes - helping keep buildings protected from leaks.

Yes. We can inspect and provide a clear scope and options so you can plan budget and sequencing.

We provide specialist waterproofing solutions across common membrane types including sheet membranes and liquid membranes, plus associated sealants and protective coatings - tailored to the substrate and performance requirements.

Yes. We support both new-build waterproofing and remediation of water ingress issues on existing properties, with a focus on durable, long-term performance.

Depending on the specification, we can waterproof decks, roofs and box gutters, external walls and selected below-ground applications (tanking), using membrane systems suited to the environment and use case.

Yes. Waterproofing systems benefit from planned inspection and maintenance. We can provide repairs, maintenance plans and proposals aimed at keeping the building envelope watertight.

Yes. We provide roof inspections and reports designed to support maintenance planning, asset condition assessments, and pre-purchase due diligence, with photo evidence and recommendations.

Yes. Where required for consenting and compliance processes, we can support PS3 documentation as part of our waterproofing delivery. ### Residential waterproofing carve-out Residential waterproofing is the one part of Access that serves homeowners directly. Everything else we do is commercial. The Q&As below cover what Gunac will and won't take on in the residential space.

We provide specialist membrane waterproofing for homeowners - particularly high-end homes - covering both new-build installation and remedial work where water ingress needs to be resolved.

Common residential applications include decks and balconies, flat or low-slope roofs, box gutters and selected external walls, plus below-ground tanking where specified.

Sheet membranes are pre-manufactured systems commonly used on areas such as decks, box gutters and roofs. Liquid membranes are applied as coatings and can suit complex shapes and detailing; they also support repair strategies such as seamless patching and recoating where appropriate.

Yes. We can support below-ground waterproofing (tanking) for areas such as foundations, retaining walls and basements where waterproofing is specified, including work on existing homes needing remediation.

Yes. We provide waterproofing repairs and maintenance solutions aimed at restoring watertightness and resolving water ingress issues. Where other trades are required to complete the remedy, we can coordinate delivery through an experienced network.

Yes. We can provide inspections and reporting to help you understand current roof/membrane condition and plan remedial work and budgets.

Yes. Waterproofing systems typically need ongoing maintenance to help the system perform at its best and to support warranty and long-term performance expectations. We can provide maintenance plans and proposals.

System life depends on the product, exposure, and installation detail. We'll recommend a system and maintenance approach that fits your use case and performance requirements.

We usually need the address, the areas to be waterproofed, substrate/type of construction, access constraints, and whether the work is new build or remedial. Pricing can also be influenced by demolition, surface preparation, access/safety requirements, and the specific product/system selected.

Yes. Where the project requires formal producer statements for consenting/compliance, we can support PS3 documentation as part of delivery.

We operate under documented health, safety and wellbeing commitments that include creating a safe and healthy working environment, proactive hazard identification, and compliance with the Health and Safety at Work Act 2015 and other relevant standards. We are Impac Prequal Totika Gold Member certified and Site Safe Sitewise Gold status approved.

Where subcontractors are engaged, they are selected based on training, systems and organisational commitment to safety, and they must complete a health and safety screening process before they can work on our sites.

We use structured health and safety systems to manage compliance records (including SWMS, toolbox meetings and incident reporting) and to keep site documentation accessible and current.

Yes. Our at-height capability includes IRATA-trained rope access (abseiling) teams, and we also use a mix of access methods such as EWP/cherry picker trucks where appropriate.

We plan site access, exclusion zones (where required), and task-specific controls to minimise risk and disruption in occupied environments.

Yes. Outdoor services can include water blasting, roof treatments, lawn mowing, hedge trimming, tree trimming/removal, stump grinding, under-house rubbish clearing and general outdoor labour support.

Yes. For portfolio or repeat clients, we can structure programme-based pricing that reflects scale, frequency, and delivery efficiencies. This supports cost certainty and simpler budgeting across multiple sites.

Yes. Where appropriate, we can work under agreed schedules of rates or preferred supplier arrangements to support efficient ordering, consistent pricing, and faster response times.

Response times depend on location, access requirements, and the nature of the issue. For urgent or safety-critical matters, we prioritize attendance and confirm expected response time once initial details are reviewed.

Lead times vary depending on scope, access, and current workload. We aim to provide clear timeframes at the inspection stage, so expectations around pricing and delivery are set early.

Yes. Where unforeseen conditions or scope changes are identified, we communicate these clearly and provide options and pricing before proceeding, so decisions can be made with full visibility.

Yes. We regularly work under main contractors, consultants, and PQSs, and can align our documentation, pricing, and delivery approach to suit project and contract requirements.

Warranty provisions depend on the system specified, installation detailing, and maintenance requirements. We outline applicable warranties at proposal stage, so coverage and responsibilities are clearly understood.

Yes. Where appropriate, we can outline alternative systems or value-engineering options that balance upfront cost, durability, maintenance requirements, and long-term performance.

Yes. Where required, we can support early-stage input to help develop practical, buildable waterproofing and roofing solutions.

Yes. We can assess current condition and outline practical options to support informed decisions around budget, risk, and asset life.

We triage requests based on urgency, safety, and operational impact, allowing urgent issues to be addressed while maintaining progress on planned programme.
