Your project in the canton of Zurich
Around the Limmat and the lake, the canton of Zurich offers a great variety of buildings. In the city of Zurich, older rental buildings, condominium flats and old town buildings stand side by side in a dense setting where parking is scarce. Winterthur, the canton's second city, has a lively old town and converted industrial districts. On the lakeshores, Thalwil, Horgen and Wädenswil have many villas and houses with views, often on slopes. The Zurich Oberland, around Uster, combines residential districts and villages, while in the north, Kloten and Bülach have grown around the airport. The canton is German-speaking, but your request can be written in English. An extension or work in an old town may involve formalities, and your municipality will tell you which. Give the municipality and postcode, building access and any restrictions in an occupied home or operating business premises.
- In the city of Zurich, mention the parking options and whether there is a lift.
- For a lakeside villa on a slope, describe access to the plot and any outdoor steps.
- For a condominium building, say whether the work concerns only your own unit or the communal areas too.
Waterproofing work in the canton of Zurich
In the canton of Zurich, the high density of buildings makes waterproofing a constant need. In the city of Zurich and in Winterthur, rental buildings and housing cooperatives have many flat roofs, inner courtyards and underground garages to refurbish, often commissioned by a property management company. On the lakeshore, in Thalwil, Horgen or Wädenswil, hillside villas and condominiums have stacked terraces and basements exposed to runoff. Around Kloten and Bülach, commercial zones require large hall roofs. In Uster, recent housing estates mainly involve balconies and green roofs. In the heart of an old town in Zurich, first ask your municipality what is permitted.
- For a cooperative building, ask for a survey of all the flat roofs in a single visit so renewals can be planned in stages.
- On a sloping lakeside terrace, have it checked that the drainage does not direct water towards the neighbour's wall.

Frequently asked questions
What existing records help assess a flat roof in Zurich?
Provide the roof plan, earlier waterproofing invoices and any known membrane specification. Describe when water ingress occurs and where it appears indoors, using safe photographs. Ask the contractor to inspect the drainage and underlying layers; do not lift the membrane or insulation to establish their condition yourself.
Why should the cause of water ingress be assessed before coating a surface?
Water may enter through joints, drains or adjoining construction rather than the visible wet patch. Provide photographs and any records of earlier work. Ask how the substrate and interfaces are inspected before a waterproofing system is selected or local repair proposed.
What should I compare in waterproofing contractor quotes?
Compare substrate preparation, membrane or resin system, joints and drainage details. Identify insulation and the final surface finish separately. Ask how the installation is checked and which conditions must be met before application, especially where the area is occupied or exposed to weather.
How should I prepare for the waterproofing contractor visit or work?
Provide safe access and existing roof or terrace documents without lifting membranes or entering unsafe areas. Identify drains and retained features on a plan. Agree protection and the sequence with adjoining trades, leaving assessment of damaged substrates and wet insulation to the specialists.
