Document what you observe
Where does moisture appear, and when? Name the affected room or outdoor area. Overview photos, connection details, plans and previous-work information help identify further checks.
Consider the build-up
The substrate, edges, penetrations and existing layers may affect planning. Discuss which parts are accessible and which checks are needed before agreeing the work.
Explain the installation
The quote should identify the surfaces and details to be treated and any assumptions. Keep concealed and inaccessible parts visible as points requiring clarification.
Your project in Aargau
Enquiries from Aarau, Lenzburg, Baden, Brugg, Wohlen and other Aargau locations are coordinated using the exact address. For coatings and waterproofing, the substrate, existing build-up and intended use matter. Photos and any plans help us prepare.
