The Kastor team helps owners look after the places they share. We start by listening to what’s happening in your building and seeing how we can help. Before you go ahead, you’ll know who your manager is, how to reach them and when we can start.
Technology helps us organise accounts, documents and requests. Our team looks after your building and remains responsible for decisions, approvals and working with suppliers.

Who we are

Oisin Lyons
Product and platform. Responsible for the product and the platform: the resident area, published accounts and the record of issues. oisin@kastor.pt

Where we work
We are starting in the Saldanha–Alameda–Campo Pequeno corridor, in the Avenidas Novas, Arroios and Areeiro parishes. Outside this part of Lisbon, we record your interest and confirm availability before going ahead.
We provide condominium management in Lisbon for buildings of 4 to 39 units; buildings with 40 or more units receive a tailored proposal. See the Lisbon service See pricing
How we work
Your proposal explains the service, timings and contact details. We check that we have room to give your building the attention it needs before we start.
A useful response
A target for a useful first response within two working days: a person, a next step and an update expectation. An automatic acknowledgement is not a resolution.
Understandable accounts
Reviewed monthly publication with an operating balance, separate reserve and supporting records. The schedule is agreed in the proposal.
Help with your requests
A manager follows issues with information on what is still needed and verification of work before closure.
Know what’s included
Scope, VAT, extras, manager, contacts, hours and start date confirmed before contracting. The condominium keeps its own bank account.
We are just starting
We are a new team starting in Lisbon, and we would rather say so plainly than show numbers we do not yet have. What we promise is in the proposal: who your manager is, what is included, when we start and the contracting entity, all confirmed in writing before you sign.
The owners’ meeting keeps all of its powers: it approves the budget and the accounts, decides on works and elects or replaces the administrator. Kastor acts within that authority, and the condominium keeps its own bank account.
Let’s talk
Tell us about your building.
Tell us about your building and what you’d like to improve. We start with a free 45-minute assessment, then explain how we can help and what it would cost.
- No commitment to switch
- In Portuguese or English
- We start by understanding what you need
