Building assessments in the Rhein-Kreis Neuss
Building surveyor in Korschenbroich
Look first, judge second.
Before a purchase, before handover, after the first crack appears: what you need is a finding, not a hunch. KNOP Bauunternehmen inspects residential and commercial buildings in Korschenbroich, photographs every finding at the component itself and sets out in writing what it means.
- Where we come out
- Korschenbroich, Kleinenbroich, Glehn and the Rhein-Kreis Neuss
- Who attends
- Viktor Knop, master bricklayer and concrete constructor
- What you receive
- A site visit, a photographic record, a written assessment

Reasons
Five situations where a proper look pays for itself
Almost every call belongs to one of these five situations. Tell us on the phone which one it is and we already know what to concentrate on when we arrive.
Before you buy
You like the house, the price is agreed, and nobody has really looked at the cellar. We walk through it with you before the notary appointment falls due.
Before handover
The shell is ready to be signed off. We go through it with you and record what is still open, while it can still be settled without an argument.
When a crack appears
A crack runs above the door and nobody can say whether it is dormant or still moving. We classify it instead of painting over it.
When a wall stays damp
The plinth is damp and the cellar smells of it. We follow the water back to the point where it actually gets in.
When two sides disagree
You and your contractor read the same spot differently. A calm record with photographs brings the conversation back to the building.
The walk through
How a site visit runs with us
We work through a building in the same order that water and loads travel through it. It sounds plain, and it is the reason nothing is missing at the end.
Around the outside
Ground levels and falls, drainage, the splash zone, the plinth junction. Where water wants to go shows outside first.
Cellar and foundations
Floor slab, basement walls, the horizontal damp proof course and any sign of rising damp.
Structure
Wall build up, openings, lintels, bearing lengths, slab edges and the crack pattern on loadbearing components.
Roof and junctions
Eaves, verges, valleys and every junction with a rising component, because that is where later damage starts.
A word before we leave
Before we drive off we tell you plainly what we noticed and what follows from it.
Whatever is accessible, we look at. Whatever stays concealed goes into the report as an open point rather than as a guess.
The result
What you are holding afterwards
A report is only useful if you can read it without a translator. Ours is written so that you can take it to the bank, to the seller or to your contractor.

- Every finding with a photograph and the exact place on the component where it was taken
- A ranking by urgency: what matters now, what needs watching, what can wait
- The open points that honestly cannot be settled without opening up a component
- Plain language that also works for someone who never sets foot on a building site
- On request, the points you should raise with the seller or the contractor
- Questions about the report answered afterwards by telephone
The report describes the condition on the day of the inspection. What happens to the building afterwards is outside it, and we say so in the document.
Enquiry
Tell us briefly what the situation is
Three lines are enough: which building it concerns, what you noticed and by when you need an answer. We come back to you and say whether a site visit is the right next step.
Knop Bauunternehmen GmbH, Frohnstr. 43, 40789 Monheim am Rhein
You can also reach us straight away by telephone. If it is urgent because a notary appointment or a handover is fixed, please say so at once.
Plain speaking
What a site visit can do, and what it cannot
An assessment becomes worthless the moment it claims more than the visit supports. So here is where the line runs, before you commission anything.
What we can tell you
- How the building stands today at every accessible point
- Whether a crack fits the picture of a dormant component or a moving one
- Where damp in a wall plausibly comes from and what should be checked next
- Which points need settling before a purchase or a handover
What we will not say
- What lies behind a closed wall while it stays closed
- A repair figure to the euro before the scope of the work is known
- Blame directed at a firm whose work we never saw being carried out
- A promise that nothing new will appear within five years
Where a question can only be answered by opening up, by a measurement or by a specialist engineer, we write exactly that into the report.
Images
Six components where a visit finds something
This is what the places we look at first actually look like, with a line on why each one matters. They are example photographs, not properties belonging to our clients.

Questions
What people usually ask first
The six questions that come up on almost every call. If yours is not here, telephone us.
What does a site visit cost?
That depends on the building and on the reason for the visit. Tell us on the phone what it concerns, how large the property is and whether a written report is needed, and we will give you a price beforehand. Without those details any figure would be a guess.
How quickly can you come?
We agree that directly on the telephone. If a notary appointment or a handover is already fixed, give us the date and we plan around it.
Do I have to be there?
It is not required, and it is almost always useful. Anyone present sees the spot for themselves and can ask on the spot. If you cannot make it, the photographs in the report carry everything.
Do you open up components?
Not without prior agreement and not without the owner consenting. A site visit assesses what is accessible. Where opening up is needed, it goes into the report as a recommendation.
Do I get the result in writing?
Yes. You receive the findings with photographs and with a ranking, in writing. The spoken feedback on site does not replace the report, it comes in addition to it.
Do you also work for buyers who have not bought yet?
Especially then. The visit before the signature is the only one whose result you can still put into the price or into your decision.
Next step
One call is enough to turn a suspicion into a finding
Tell us which building in Korschenbroich it concerns and what you noticed. Everything else we settle quickly and without detours.
