Technical & Building Maintenance
In-house preventive inspections, rapid emergency interventions, structural upkeep, and routine care of common areas.
Condominium, rental and short-term rental management with our own construction team, delivering rapid repairs, lower maintenance costs, and no delays.
Chave 100 Demora grew out of years of building construction and rehabilitation. Today we manage condominiums, rented apartments and short-term rentals on the south bank of the Tejo with our own construction crew. When something breaks, you don't wait for a contractor: we fix it. We handle the accounts, the assemblies and the paperwork too, so you can stop worrying about the day-to-day running of your property.
We don't hire a contractor for every breakdown. The work is done by our permanent crew — and that changes everything in the daily life of your building.
Our own crew on site, with no waiting on subcontractors.
Clear budgets, fees kept current, and accounts any owner can read.
Work carried out and checked by us, with someone accountable for it.
