What a finishing contract must include before you sign: clauses that can't be missing

Because most conflicts between owners and contractors in Medellín and Bello start from verbal agreements: prices that change partway through, timelines with no consequence, and a scope that was never made clear from the start. A written contract is what turns a promise into something enforceable.

A fixed price broken down by space or phase (not a single lump sum with no detail). A schedule with a start and delivery date, and what happens if it's not met. The exact scope: what's included and what isn't — for example, whether kitchen appliances are part of the price. A written warranty, with a minimum duration and what it covers. And payment terms tied to verifiable construction progress, never a single 100% upfront payment.

A good contract defines how it's handled: any change in scope (for example, hidden humidity found during a renovation) must be documented in writing, with its impact on price and timeline, before it's carried out — never as a surprise overcharge at the end.

Yes. Every quote confirmed with Yainis Ávila is put in writing with a fixed price, a schedule in weeks, and a minimum one-year warranty — before any work begins.
