Rarely have I received such good, quick advice on site.
After 2 days I had the cost estimate and because it was right, my 3x9 meter garage was completely removed from the Rhine gravel and completely re-insulated in the next 2 days. I'm no expert but what I saw was a top installation, all corners individually sealed and everything sealed again all around. Simply great, so there are still some very good companies in Bochum.

1Positive: The unusual drainage construction was professionally implemented.
1Negative: The installation week was fixed by telephone but the employees arrived unannounced. They were lucky that I was there.
1 Negative: An existing DN 100 cast iron pipe was shortened with an angle grinder, but the cuttings were not removed. Result: after one day of continuous rain, an approx. 1 m² rust stain on the decking.

2 Positive: The working time of the fitters was 2x 6 hours on site, exactly as stated in the quotation.
2 Negative: An additional 3 working hours were invoiced for setting up and loading the van. Amount of material: 2m copper pipe DN 100, 2m gutter, 7 gutter hooks and some fittings, end pieces and small parts. Too expensive for 250€ gross.

Wilhelm Grauthoff GmbH Comment from Wilhelm Grauthoff GmbH:
Dear Mr. Schiller,

Thank you very much for your feedback. Your opinion is very important to us and this is the only way we can improve.

I am pleased to hear that you are satisfied with the craftsmanship of our work. I would like to comment briefly on the other points:

- You are right that the exact date was not agreed. We fixed the week and it was clear to us that we could work on the construction site without you being there. Sometimes free dates arise at short notice and we are glad that we were able to keep to the previously agreed week given the volume of work and the weather conditions.

- Unfortunately, the debris on the terrace was not visible. We swept up the debris and took it away. Some light dust may remain. The dust only bonded and changed color when it rained. As discussed on the phone, we even cleaned the terrace afterwards. According to them, it could be removed by themselves.

- The offer was estimated both in terms of time and material due to the complexity. However, the unit prices of the materials did not change at any time, which is why only the quantity of materials should have been open. Additional work was still commissioned, so it took us a little longer and we also needed a little more material.

I hope that I have been able to explain our point of view and that it is reasonably understandable. I really appreciated working with you and would be delighted if we could continue to work together in the future.

MfG
Rosenbach

Dachdecker Grauthoff is a family business that is always on hand with help and advice and always works cleanly and reliably.
That's why we are always happy to use him and thank him for the great work he has done so far.

We have had very good experience with the Grauthoff company. It was a rather small order. Slate tiles had to be attached to our dormers after windows were replaced. The employees were very punctual, completed the work quickly and conscientiously and left the site clean and tidy. Any time gladly and with good feeling again!

We had our flat roof completely renovated by Grauthoff in 2020. We received very good advice overall. Therefore, we have in subsequent years further work (eg balcony renovation) carried out by the company. We are very satisfied with the results and can continue to recommend Grauthoff.

We had our private house insulated and covered at the beginning of the year. From the quotation to the final completion, we felt very professionally looked after. The team on site was competent, friendly and helpful. The interaction with the bosses and with each other gave us the impression of a harmoniously functioning team. Gladly again.

Grauthoff carried out a flat roof renovation and the sealing of several patio windows on my house in the spring. I am still more than satisfied with the work even after half a year! A super friendly team, the bosses and employees are super helpful and have implemented the work from the initial planning to completion without complications. Would hire the company Grauthoff again at any time and gladly give my recommendation. Many thanks to the entire team! :-)

The team I know always shows a friendly approach with whom you can also discuss your idea of how to fix the damage.
The reliability in the request for a quote, such as the promised
date for execution is also OK.

Even if there were adjustments in the product selection (windows too large), the company Grauthoff has reacted flexibly and quickly. All craftsmen, roofers, as well as interior finishers have worked cleanly and accurately.
