Building assessment
Certainty before buying or selling a property
Before a property is bought or sold, a technical building assessment establishes what condition it is genuinely in. Jakob Birkmann inspects existing defects, evaluates the scope of renovation required and sets out clear recommendations on suitable renovation measures and the costs to expect.
Technical building assessment
Expert evaluation of the condition of the building, its components and the existing structural fabric.
Defects and deficiencies
Recording and assessment of visible or suspected building defects and construction deficiencies.
Renovation recommendations
Specific recommendations on sensible and necessary renovation measures.
Costs and renovation concept
Estimate of the renovation costs to expect and development of a clearly reasoned renovation concept.
Problem areas
Typical building defects we resolve
Building defects are often complex and their cause is rarely obvious at first sight. A wrong assessment can lead to substantial follow-up costs.
Damp & mould
Damp walls, a musty smell, visible mould – we identify the underlying cause.
Cracks & structural issues
Professional evaluation of cracks in masonry and of building settlement.
Water damage & pipe defects
Locating leaking pipework and assessing the resulting consequential damage.
Unexplained defects
When something is clearly wrong but nobody can say what – we provide clarity.
Our approach
A clear technical assessment instead of uncertainty
I assess building defects, renovation projects and existing buildings systematically and transparently. You receive a clear evaluation together with specific recommendations that can actually be implemented on site.
That gives you a sound basis for decisions about your property or construction project – without unnecessary risk.
