Waterproofing in Chiado, Lisbon
In Chiado, waterproofing assessment looks at roofs over shops, details against taller walls and drainage in light wells, without choosing a system before the substrate is seen.
Assessment is for the stated property; this page does not conclude the cause remotely or represent a local office or a completed job in the area.

Chiado mixes Pombaline plots with buildings reconstructed after 1988. Ground-floor shops under housing are common, along with shared roofs, light wells and junctions between blocks of different heights.
Access for the assessment
Access may require a roof key plus permission from the ground-floor shop and the apartment above. Narrow stairs and shop hours constrain the visit; identify who can open each space.
Surface and intended use
Identify the existing substrate, interfaces and intended use without choosing a product before assessment.
Roofs over shops
In Chiado, say whether water appears on the shop ceiling, in the home above, or in both, and whether a terrace or roof can be reached.
Junctions and light wells
Identify details against neighbouring walls and light-well areas where water runs, without climbing an unsafe roof.
What to provide for a quotation
- Approximate surface size and access
- When water appears and its relationship with rain
- Safe context and detail photographs
- Existing system and earlier work, if known
Can a system be chosen from photographs alone?
No. Photographs help prepare assessment, but substrate, moisture, drainage, detailing and compatibility may require a visit.
Does a stain on a shop ceiling in Chiado show the source?
No. The stain does not assign the source to the apartment above or to the roof. Assessment separates envelope ingress, drainage and pipework, and needs access to each space.
