After a heavy rain I noticed moisture appearing in the corner of the basement. It looks like water is leaking through the roof and walls. I would like to find a plumber who can not only fix the drainage but also check the roof. Are there any specialists who deal with both the roof and the drainage system?

This could be due to problems with both the roof and the drainage system. It is recommended to find a plumber who works in conjunction with roofing experts. It is important to conduct a full inspection of the roof and drainage system to rule out possible causes of leaks. Also, check whether the company provides guarantees for its work.

Thank for you!
