Coastal properties deteriorate quietly. Marenn is the trusted presence on the ground — monthly HomeChecks, complete documentation and genuine peace of mind for owners who care about what they've built.
Salt air corrodes. Moisture creeps in. Storm damage goes unnoticed for weeks. A slow leak under the kitchen becomes a structural repair. A pool pump runs dry and fails. Mail piles up, signalling vacancy to the wrong people.
None of it announces itself. It accumulates quietly between visits — and you only discover it when you arrive, or when the bill arrives. Marenn exists to be there in the months you can't be. Not a quick walk-through. A methodical, documented HomeCheck by a steward who knows your home and reports back within two hours of leaving it.
Salt air, humidity and storm exposure are relentless. A coastal property left unchecked for four weeks is not the same property you left. These are the issues Marenn members stop worrying about.
A slow leak under a basin. Condensation behind a wall. Rising damp through an unsealed slab. In a coastal climate, moisture finds every gap — and mould follows within days. Left undetected for a month, remediation becomes a major works project.
Salt air attacks exposed metal, window seals, roofing, balustrades and air conditioning units. The deterioration is gradual and invisible until it isn't — a corroded anchor, a failed seal, a compromised roof joint that turns a heavy rain into a ceiling collapse.
A storm passes while you're interstate. A roof tile shifts. A fence section comes down. Water enters through a compromised seal. No one notices for three weeks. By the time you arrive, the damage has multiplied. A post-storm HomeCheck changes this entirely.
Pool pumps run dry and burn out. Hot water systems fail and flood. Air conditioning units develop faults that compound with continuous running. These failures are almost always detectable before they become expensive — if someone with the right knowledge is listening.
An overflowing letterbox. Accumulated deliveries. Unchanged curtains for months. Coastal holiday areas are not immune to opportunistic entry. Visible regular activity — a car in the drive, lights that change, mail that disappears — is one of the most effective deterrents there is.
Coastal properties attract possums, rodents and insects in ways inner-city homes do not. A gap in the eave, a missing vent cover, a disturbed roof section — and you have a nest in your roof cavity. Marenn identifies entry points and signs of activity before an infestation takes hold.
Each HomeCheck visit follows the same rigorous sequence — every room, every system, every external area. Nothing is skipped. You receive a complete report within two hours of Marenn leaving the property. The same protocol, every time, for every property.
Your steward verifies their identity with a biometric selfie before every visit. Access is via an encrypted Bluetooth key safe — no codes shared, no keys that can be copied, complete audit trail from the moment they arrive.
Audited & TimestampedA full letterbox signals an empty house. We clear it on every visit, photograph each item and follow your instructions on forwarding or disposal. A small detail that matters more than most owners realise.
Chain of CustodyEvery room, system and external area photographed to a consistent standard — then compared against last month's record using computer vision. The system analyses each image at a pixel level, flagging anything that has changed: a watermark that wasn't there, a crack that has widened, a surface that has shifted. This happens before your steward leaves the property. Not reviewed later. Caught in the room, in real time.
Computer VisionAir conditioning, pool equipment, hot water, irrigation — each recorded on video with audio every visit. The system maintains a baseline of what your equipment sounds and looks like when functioning normally. Variance from that baseline is flagged. A problem developing over months is caught long before it becomes a failure — and long before you arrive to find it.
Baseline MonitoringEvery HomeCheck builds your property's permanent condition archive. Over time this becomes something no one else can give you: a complete, timestamped record of your home's health — there for insurance claims, maintenance decisions and genuine peace of mind.
Because every HomeCheck is indexed against the same baseline, the system identifies trends no single visit would reveal — a recurring damp patch after rain, a crack that has measurably widened, a pattern of minor issues concentrated in one area. The difference between a snapshot and a story.
Your Property ArchiveWhen something needs attention, we connect you with a vetted local tradesperson, coordinate access and confirm completion. You approve. We handle it. You hear about it when it's done — not months later when the damage has compounded.
One-Tap ApprovalSet your bedrooms and bathrooms, select any features that apply and your quote updates in real time. Annual membership includes two months free.
Annual membership: 12 months billed monthly or upfront (10 months' cost — two months free). Monthly rolling thereafter. Your onboarding visit is your first HomeCheck. We install your key safe, establish your Digital Home Record and conduct your baseline HomeCheck — all in one visit. Monthly HomeChecks follow from there.
Peace of mind isn't a feeling. It's a report in your inbox within two hours of Marenn leaving your home. The Marenn Standard
The monthly fee is the smallest number in the equation. The real numbers are what you spend — in money, time and stress — when problems are discovered late.
A slow leak caught in month one costs a plumber's callout. The same leak discovered six months later costs remediation, potential mould treatment and possibly flooring replacement. The difference — in almost every case — is simply whether someone was there.
Marenn members consistently find that a single early catch covers months of membership. The service doesn't need to justify itself often. It only needs to justify itself once.
When it comes time to sell, a complete condition archive covering years of monthly HomeChecks is a genuine asset. It de-risks the buyer's due diligence, removes the "unknown condition" leverage buyers use to negotiate and supports your asking price with evidence rather than assertion.
A property with a provable, professional maintenance record is a different proposition to one without.
You bought a coastal property to enjoy it. Marenn ensures that every time you walk through the door, the systems are running, the pool is clean, the air conditioning is working and nothing is waiting to surprise you.
The first hours of a visit should not be spent finding problems. They should be spent exactly where you intended to spend them.
Remote coordination of emergency repairs. Unplanned tradesperson visits that require someone to be present. Managing contractors from interstate while trying to work. The accumulated stress of not knowing what's happening at a property you care about.
The monthly cost of Marenn is modest against the hours — and the mental load — it removes from your life every year.
Straight answers. If something isn't covered here, reach out — we'll respond within one business day.
Coastal properties deteriorate quietly when no one is watching. A slow leak under a basin becomes a structural repair. A pool pump runs dry and burns out. A roof tile shifts in a storm and water enters for three weeks before you arrive. Salt air corrodes seals, metal and surfaces in ways that are invisible until they aren't.
Marenn puts a trusted, knowledgeable presence in your home every month. A steward who knows what to look for, documents everything and tells you within two hours of leaving. That's the problem we solve: the gap between the last time you were there and the next time you walk through the door.
Owners of coastal second homes, high-value residences and investment properties that sit vacant for extended periods — whether you're interstate, overseas, or simply unwilling to rely on a neighbour's best intentions.
Particularly suited to properties in salt-air environments where deterioration is accelerated and the cost of delayed discovery is high.
A neighbour means well. A property manager is focused on tenancy. Neither produces a timestamped photographic condition report, records your mechanical systems on video, compares this month's images to last month's with AI assistance, or maintains a permanent archive of your property's health.
Marenn is not a letting service. It is a stewardship service — built entirely around protecting the condition of your home and giving you verifiable peace of mind from wherever you are.
Every HomeCheck follows the same rigorous sequence:
No. HomeCheck is a visual stewardship service — not a licensed building, pest, electrical or structural inspection. We do not open walls, conduct destructive testing, or certify compliance.
Where something needs specialist assessment, we flag it clearly and connect you with the right licensed professional through Marenn Prevent.
Yes. No service eliminates risk entirely. Hidden defects, latent structural issues, or a storm in week two of a four-week absence can still cause damage. HomeCheck dramatically reduces the window in which issues go undetected — but it is a preventative monitoring service, not a guarantee against damage or loss.
Clients remain responsible for maintaining appropriate building and contents insurance.
Access is managed via a Bluetooth Master Lock key safe, installed at your property during onboarding. There are no codes shared, no keys that can be duplicated without your knowledge and access can be revoked remotely at any time.
All entry is timestamped, audited and documented. Access methods are agreed and confirmed in writing at onboarding.
All Marenn stewards are police-checked, vetted and reference-checked. We recruit locally and deliberately — our stewards are established members of the communities they work in, with genuine stakes in the areas they serve. Before every HomeCheck, your steward verifies their identity with a biometric selfie — creating a complete, audited chain of custody from the moment they arrive.
Marenn holds public liability insurance and professional indemnity insurance. Every steward operates under our company coverage and is required to maintain professional presentation and conduct at all times. Certificates of currency are available on request.
You are notified promptly via WhatsApp Business or email, with photographs. Where you have pre-authorised us to act — turning off the water supply if a leak is detected, moving outdoor furniture ahead of a storm — we will do so immediately and report back.
No non-emergency work is ever undertaken without your explicit approval.
Your report is delivered within two hours of your steward leaving the property. Our preferred delivery method is WhatsApp Business — photos, video and written notes in a single organised thread, creating a running record of every conversation about your home in one place.
Reports can also be delivered via email on request.
Your Digital Home Record is your property's permanent condition archive — built incrementally with every HomeCheck. It contains the full photographic history, noted maintenance items, completed works and mechanical system recordings.
Over time, this becomes a genuinely valuable asset: a complete, timestamped record of your home's condition that supports maintenance planning, capital works decisions and — as Marenn develops its risk platform — potential insurance optimisation.
A human reviewing last month's photos alongside this month's is working from memory and attention. Both are fallible, particularly across dozens of rooms and hundreds of images. Our computer vision system compares images at a pixel level — same room, same angle, same frame — and flags specific areas where change has occurred, with the changed region highlighted for the steward to physically re-examine before leaving.
The practical difference: a faint new watermark on a ceiling, a hairline crack that has widened slightly, a small area of paint that has bubbled. These are changes a conscientious human might notice. They are changes our system will always notice. The combination — computer vision identifying, human steward verifying on the spot — is more reliable than either alone.
Marenn Prevent is our vetted trade network. When a HomeCheck identifies something that needs attention — a plumber, electrician, pest controller, or maintenance contractor — we connect you with a qualified, trusted local professional.
You approve the work. We coordinate it. You hear about it when it's done. Trades are independent licensed contractors; their compliance responsibilities remain their own. Where Marenn receives a coordination fee, this will always be disclosed.
No. Marenn Prevent is a convenience, not a requirement. You are always free to engage your own contractors. We can liaise with them directly if you prefer — providing access, briefing them on findings and coordinating attendance around your schedule.
HomeCheck is priced monthly based on your property's specific configuration — number of bedrooms and bathrooms, plus any features that add HomeCheck time: pool, garden and grounds, multi-storey layout, garage or studio, tennis court, or jetty.
Use the pricing calculator on this page to get an instant quote for your property. Pricing starts from $249 per month — the equivalent of $58 per week for a property worth protecting.
Your onboarding visit is your first HomeCheck. In a single visit we conduct a full baseline HomeCheck of your property, establish your Digital Home Record, install your Bluetooth Master Lock key safe and configure your HomeCheck template. The monthly HomeCheck cadence begins from there.
The onboarding fee reflects the cost of that first HomeCheck, the key safe hardware, the Digital Home Record setup and the coordination time involved. It is the foundation against which every subsequent HomeCheck is measured — and what makes the AI photo comparison possible from day one.
This baseline is the foundation everything subsequent HomeChecks are measured against — that's what makes the AI comparison and Digital Home Record possible from day one.
HomeCheck operates on an initial 12-month minimum term, after which membership rolls monthly and can be cancelled with 30 days’ written notice. We think of the first year as the period where the service proves its value — your Digital Home Record is established, seasonal patterns are documented and the AI comparison starts to show its depth. After that, your continued membership is entirely your choice, and we believe the service should earn it.
Your HomeCheck photography, condition records and property history are stored securely and used to deliver your service. We may use anonymised, aggregated data — never personally identifiable — to improve our platform and develop future services.
We do not sell your personal data. All data is handled in accordance with Australian Privacy Law. Where future products require additional data use, we will seek your explicit consent.
Possibly. Marenn is building toward a risk platform that may, in time, integrate with insurance providers — using the longitudinal condition data in your Digital Home Record to support better risk assessment and potentially more favourable coverage terms.
HomeCheck itself is not an insurance policy and joining HomeCheck does not obligate you to participate in any future product. Any insurance offering will be clearly disclosed and appropriately regulated.
We launched in Noosa and the Sunshine Coast because this is home. Expansion to Australia's other great coastal enclaves follows as we grow.

We'd owned the Noosa house for eleven years. For the first eight, something was always wrong when we arrived — a leak, an equipment failure, something we had no idea about until we walked in. Since Marenn, two things have been caught early. Nothing has surprised us. That's what we were paying for.
