Benefits
The cost of not looking.
Every year you do not inspect the exterior fabric of a large building, the bill quietly grows. The numbers below are what the industry has measured, over and over.
€20x
Repair costs later vs. repair now
A defect caught early typically costs a twentieth of the same defect once water has reached the structure.
78%
Of period homes carry an unseen defect
Roofs, valleys, flashings and chimney heads — almost never visible from ground level or from inside.
€42,000
Average cost of a late-caught roof failure
Structural timber, ceilings, decoration and lost use of rooms, on a single elevation of a large house.
3 yrs
From hairline crack to structural repair
The usual window between a defect becoming visible from the air and it becoming a builder's job.
Most buildings are surveyed within 2-3 weeks of enquiry.
Why it matters
Small defects on large buildings do not stay small.
A cracked tile is a fifty-euro problem in March and a five-figure ceiling in November. On a large historic building, the failures that cost the most are almost always the ones nobody could see: a blocked valley behind a parapet, a hairline crack in flaunching, pointing washing out of a chimney on the weather side.
An annual scan catches those while they are still cheap. It also gives you something most owners never have — evidence. Dated, consistent, complete documentation that stands up with insurers at renewal or after a claim, with buyers during a sale, and with heritage authorities when consent depends on showing how the fabric has been maintained.

Country Estate in The Netherlands. External inspection by Henry Wynaendts on 21 September 2026, supported by 36 detail photographs and an estate overview.

A raised chimney apron and an open-looking ridge fold were flagged for closer inspection. The photographs do not establish an active leak.

Selective pruning will expose concealed wall details. Inspect the newly visible areas before deciding on repairs.
