Building assessment in the Rhein-Kreis Neuss
Building surveyor in Kaarst
Look first, judge second. And everything we see, you receive in writing.
A property you want to buy in Büttgen, a handover due in Vorst, a crack that has grown since spring: a suspicion gets you nowhere, a finding does. KNOP Bauunternehmen inspects your building in Kaarst, records every observation exactly where it sits and tells you what it means.

- Who comes A master craft company that has built since 2008
- What you get Site visit, photographic findings, written assessment
Reason to call
Four questions we answer most often in Kaarst
Almost every call fits one of these four questions. Tell us which one is yours and the site visit is set up correctly before we even drive out.
-
01
Is the fabric worth the price?
You want to buy and the notary appointment is fixed. We walk the property with you before you sign and tell you what the load bearing parts, the roof and the cellar really offer.
-
02
Can I accept it like this?
A shell or a flat is about to be handed over. We walk the components with you and write down what is still open before you sign.
-
03
Is this crack still moving?
Above the door, at the corner of the building, in the plinth. We classify the crack pattern instead of painting over it and tell you whether it has come to rest.
-
04
Where is the damp coming from?
A cellar, a plinth or an external wall will not dry out. We follow the water until we find the point where it gets in.
Your case is not listed? Describe it briefly in the enquiry. We will tell you openly whether we are the right people for it.

How it runs
From the call to the file
Four steps, always the same ones. From the first phone call you know what comes next and when you will hold something in your hand.
-
Step 1
Phone call
In a few minutes we establish what it is about, what you need and whether a site visit is the right step for your case at all.
-
Step 2
Site visit
We come to Kaarst, work through the accessible components and photograph every observation exactly where it sits.
-
Step 3
Classification
We sort the photographs by component, record what belongs together and keep observation cleanly separate from assessment.
-
Step 4
The file
You receive the photographs with a description and an assessment, in a form you can pass to a seller, a trade or your bank.
How long a visit takes depends on the property. You get that estimate beforehand, not afterwards.
What we check
The line we work along
We look from building practice, that is along the components that have to carry, drain and stay tight. What is accessible, we inspect. What stays hidden is listed as an open point in your file.

- Ground and foundation
- Position of the slab, plinth junction, ground level at the house and the barrier against rising damp.
- Load bearing walls
- Wall build up, openings, lintels, bearing lengths and the crack pattern on the load bearing parts.
- Floors and bearings
- Slab edges, bearing, deflection and the junction between the floor and the masonry.
- Concrete and reinforcement
- Surfaces, construction joints, concrete cover and everything still visible before the pour.
- Water at the building
- Drains, ground falls, the splash zone, the cellar entrance and the drainage of the roof.
- Facade and junctions
- Render, facing brickwork, window junctions, parapets and the transitions to every rising component.
Photographs
Six sheets from our own work
This is what a sheet looks like with us: the picture, and underneath what can be seen. Every photograph comes from a site of the company and shows components, not damage cases.
-
Sheet 01
Ground at the excavation
What is shown The soil layers standing in the open face of the pit, beside the gravel bed laid for the foundation.
-
Sheet 02
Drain at the wall foot
What is shown Green drain beside the cellar wall, waterproofing and protective layer carried down below the later ground level.
-
Sheet 03
Reinforcement before the pour
What is shown Reinforcement laid on spacers above the separating layer, starter bars set for the rising components.
-
Sheet 04
Waterproofing in the pit
What is shown Continuous waterproofing membrane on the pit floor, laps overlapped, formwork beams as edge restraint.
-
Sheet 05
Floor under construction
What is shown Floor planks laid, bearing on the masonry visible, edges prepared for the in situ concrete.
-
Sheet 06
Facade behind the scaffold
What is shown Scaffold lift in front of the facade, wall opening left out, the plinth junctions stay accessible.
What can be seen at your property is decided by the site visit, not by this sheet.
The file
What you hold afterwards
Not a pile of photographs without context, but a file you can work from, hand to a trade or negotiate with.

-
Picture and place
Every photograph with the component it was taken at.
-
Observation
What can be seen, in one sentence and without judgement.
-
Assessment
What follows from it and how urgent it actually is.
-
Open points
What stayed hidden and what opening up would be needed for.
The file is an assessment from building practice. It does not replace a court expert report and does not pretend to be one.

Plain words
What we do and what we do not
So that nobody calls with the wrong expectation, this stands up here and not in the small print.
We do this
- Inspect accessible components and record every finding photographically.
- Classify from our own building work what an observation means for the component.
- Walk a purchase, a handover or a conversion with you and name the open points.
- Say so when a finding needs an investigation that goes further than ours.
We do not do this
- No expert report for a court and no evidence gathering in proceedings.
- No statement about components that stay hidden and are not opened up.
- No energy certificates and no market value assessment.
- No assurance we cannot prove at the component.
Questions
What people usually ask first
The answers we would give you on the phone as well.
How quickly can a site visit happen?
That depends on what is running on the sites at the time. Call or write, and we will name you a date we can keep rather than a hope.
What does an assessment cost?
That follows from the property and the extent. We tell you the range before we drive out, so you can decide in peace.
Do I have to be there?
It helps. You see for yourself what the file later talks about and can ask straight away. It is not essential as long as someone unlocks.
Do you look at flats and commercial buildings too?
Yes. House, flat, hall or extension: what matters is what is accessible, not the use.
Are you a publicly appointed and sworn expert?
No. We are a master craft company and judge from our own building work. If your case needs an appointed expert, we tell you that on the first call.
How far do you travel?
Kaarst and the Rhein-Kreis Neuss are our area. For anything just beyond it, simply ask.
Next step
The finding first, the decision after
One call is enough to settle whether a site visit in Kaarst helps you. If it does not, we say so just as plainly.
