This is what happens to your home when the people building it either don’t know this detail or know it and skip it anyway.

The flush threshold is everywhere in modern builds. Terrace level with the living room floor, no step, dead clean. Buyers love it. But it’s one of the easiest details to get wrong, and when it’s wrong, water comes straight in under the door.

Done properly it’s not complicated. The ground slopes away from the house. A drain sits just below floor level across the doorway and carries water off. The waterproofing climbs up behind the frame like a hidden wall and gets buried out of sight. Flush is just the look — the barrier’s still there behind it.

The trouble is half the trade either doesn’t understand how water actually moves, or understands fine and cuts the corner to save a day and a few euros. Either way it’s not their problem once they’ve been paid. It’s yours. And you don’t find out until the mould comes through the corner of a wall or your timber floor begins to rot.
None of it shows up at a viewing. All of it is expensive once it declares itself.

If you’re buying, renovating, or just want a straight answer on whether a detail’s been done right get in touch. We do independent building inspections across northern Portugal, and we’re happy to give advice before you commit.

An excerpt from our builders notes blog:

Here's something most foreign buyers don't know. In Portuguese residential construction there is no mandatory certification for individual tradesmen. Anyone with a van and a logo can call themselves a builder. The flip side surprises people even more — a big, well-marketed renovation brand is not automatically safer. Plenty of the glossiest names in the sector are franchises: they sell the job, take their margin, and subcontract the actual building work to whoever is available…. Follow the link to read more

No mandatory certification, glossy franchises that subcontract, the engineer behind the website, reviews you can't trust, deposits to firms that vanish — who you're really hiring, and how to protect yourself, when choosing a builder in Portugal.

Property owners.
If you’ve Googled “renovation Porto” or “roof repair Porto”, the first three pages of results are full of building companies — different names, different logos. A lot of them are the same operator running multiple websites or single entities posing as builders. Same template. Same fake photos. Same copy paste text, some even with the previous builders name accidentally copied over 🤣. No NIPC, no alvará, no real address. They’re not builders. They’re call centres that ship your job out to whoever’s free that morning or a franchisee.
This setup protects them. No company name on the contract, no alvará, no real entity behind the website means there’s no one to sue when it goes wrong. The whole thing is engineered to make sure they can take your money, do a botched job, and disappear with zero liability. When the roof leaks six months later, the the phone number’s dead, and the “company” you paid never legally existed in any form you can pursue. That’s why they do it. People lose tens of thousands and have nowhere to go.

Two step check before you trust anyone:
1. Search them on impic.pt — Consultar → Alvarás de empreiteiro de obras particulares.
2. If there’s no NIPC published on their website, walk away.
