Tradespeople
Old buildings require specialists who understand historical construction methods. This piece looks at where to find qualified contractors in the Czech Republic and what to ask them.

Key Topics
Old footings are often shallow rubble foundations. Knowing how to read settlement cracks and moisture patterns determines the scope of any repair work.
Pre-war Czech homes rarely have modern damp-proof courses. Correcting capillary moisture without trapping it behind new finishes is a recurring technical challenge.
Original roof trusses made from slow-growth timber are often sound but under-dimensioned by current standards. Grading and reinforcing rather than replacing is usually preferable.
Using modern Portland cement mortars on older brick or stone walling traps moisture and accelerates spalling. Lime-based mixes remain the appropriate choice in most historic contexts.
Buildings protected under Czech monument law (zákon č. 20/1987 Sb.) require approval from the Regional Heritage Office (NPÚ) before structural changes can proceed.
Adding insulation to old masonry needs careful detailing to avoid interstitial condensation. Interior insulation with vapour-open mineral boards is one approach used in current Czech practice.
