Condominium management — Lisbon
The building thatruns itself.
Automated administration, supervised by a named human who answers within 24 working hours — em português or in English.
O problema — The problem
Every building in Lisbon knows these sentences by heart.
These are not our words. They are real complaints filed by Portuguese owners against their administrators — Lisbon leads the country in them, and fewer than half are ever resolved.
“Depois do prédio virar cliente, nunca estão disponíveis.”
Once the building becomes a client, they're never available again.
“Não recebo resposta aos emails.”
I get no answer to my emails.
“Não apresenta contas e recusa aparecer na assembleia.”
Won't present the accounts. Won't attend the assembly.
“Não me foram entregues as atas.”
The minutes were never given to me.
“Há 4 anos que reclamo.”
I have been complaining for four years.
“Mau serviço, negligência e incúria.”
Bad service, negligence — contempt.
Condominium management in Portugal has never had to be good — Excel, paper, silence, and a phone that rings out. Kastor was built to be the opposite of every sentence above, and to put that in the contract.
A promessa — The promise
Four guarantees. Written into the contract, not the brochure.
Every euro, visible. Always.
Your building's accounts live online — balances, invoices, the reserve fund, who has paid and who hasn't. Not a PDF once a year. A ledger you can open on your phone, today.
Answered in 24 working hours.
Any incident, any question — answered in writing within one working day, in English or Portuguese. Nothing handled by phone without a record. This is a contractual term, not a slogan.
Accounts published by the 8th.
The monthly statement is on the portal by the 8th of every month. Every month. It has never been done in this market; that is precisely why we do it.
Your building, surveyed annually.
Once a year: a written building-condition report and a multi-year works plan, so the assembly decides with facts — before the façade becomes an emergency.
If we break any of these guarantees three times in a year, the condominium may terminate the contract — without notice, without penalty.
No other administrator in Portugal offers this clause. We can, because our systems make the promise cheap to keep — and losing you expensive to us.
O portal — The owner portal
Everyone says transparência. We show you the ledger.
This is your building on Kastor: every quota, every invoice, every policy and every euro of the reserve fund — live, from any country, in Portuguese or English. The monthly statement is published by the 8th. You will never again ask where the money went.
- One bank account per building — segregated, always
- Every invoice attached to its movement
- Debtors chased on a fixed, automatic calendar
- Reserve fund funded and visible, as the law requires

Proprietários não residentes — Non-resident owners
You will finally know what is happening in your building — from 2,000 km away.
Portuguese condominium law assumes you are in the room. The assembly binds you whether you attend or not — in a language you may half-follow, about money you cannot see. Kastor was designed, first, for the owner who is not there.
Everything in English. Natively.
Minutes, notices, reports, the portal, your named contact — bilingual by default, not on request. No lawyer needed to read your own building's decisions.
Join every assembly by video.
Videoconference attendance and proxy voting are your legal right — we are among the few who actually run it. Agenda in both languages, in advance.
A quarterly letter from your building.
Four times a year, in plain English: the accounts, the works, the decisions coming up. You will never again be surprised by a levy.
Your rental, coordinated.
If you let your unit, we coordinate with your tenant, cleaner or check-in crew as a managed add-on. One contact for the whole asset.
“A sua fração é, provavelmente, o seu maior ativo em Portugal. Merece uma administração que responde, apresenta contas e fala a sua língua.”
“Your apartment is probably your largest asset in Portugal. It deserves an administrator who answers, shows the accounts, and speaks your language.”
Serviços integrados — One accountable contract
The administration is the core. The building care comes with it.
Cleaning
Common areas, vetted crews, photographed schedules.
Preventive maintenance
The “cared-for building” plan: small fixes before they become works.
Works coordination
Three quotes by law, supervised on site. 6–8% — published, not hidden.
Insurance
Mandatory fire cover placed, renewed, and visible on the portal.
Debt recovery
Letter, call, plan, lawyer — on a fixed calendar, within the legal 90 days.
No finger-pointing between the administrator, the cleaner and the builder — one contract, one standard, one party accountable to your assembly.
Mudar de administrador — Switching is our work, not yours
Your board lifts a finger once: to vote.
Invite us
To your next assembly — or to a 30-minute call with the board first. We present in Portuguese, English, or both.
The assembly votes
A simple majority is all the law requires. We prepare the proposal, the comparison, and the minutes language for you.
We do the entire handover
We audit the balances, transfer the funds to a segregated account, collect every document from the old administrator, and report what we found — including any problems, immediately.
First month free. No long tie-in — our termination clause protects you, not us.
Preços — Published, like everything else
The only administrator in Lisbon with the price on the website.
We are not the cheapest, deliberately. The fee funds the guarantees: the 24-hour answer, the day-8 accounts, the annual survey, the bilingual everything. If a price hidden behind “request a quote” feels more trustworthy to you, we are not your administrator.
