In 2024, our apartment building in Dortmund experienced two major pipe blockages in quick succession, and we sought a competent company to repair the damage as quickly as possible.

In January 2026, we experienced a tricky leak in the sewer pipe under our house. Thanks to the expert advice, outstanding service, and high level of competence, we received quick and reliable assistance. Many, many thanks!

We had a burst pipe. After our initial contact, an on-site inspection was arranged very quickly, and the necessary repairs were organized immediately. The entire job was carried out swiftly, professionally, and with exceptional cleanliness. Everything is working perfectly now. We are very satisfied with the workmanship. Despite the unpleasant circumstances, we can confidently say: This company works reliably, precisely, and professionally – a clear recommendation. Thank you for the excellent work.

We are truly very satisfied! Several underground pipes in our building were completely damaged and blocked – not an easy or pleasant job, as the entire ground had to be excavated over a depth of 11 meters. A lot of manual work and considerable force had to be used for milling. All the more impressive, then, was how calmly, professionally, and quickly the team handled the entire situation. Others gave up – but here, they just got on with it! Everyone was very friendly and explained everything clearly. In the end, the problem was completely resolved, and everything was left tidy. Many thanks

Highly competent and friendly staff. JL worked for us for a week on a sewer rehabilitation project and did a clean and efficient job. The team left the site tidy every day, and we are completely satisfied. We would hire JL again anytime and highly recommend them.
