Depending on what needs to be done and how long the work on the site will drag on. In any case, you need the master to come to you and assess the whole situation himself. I advise, if anything, contact POM Plumbing https://pomplumbing.ca/industrial-plumbing/. They can, by the way, send you a price list on request. And they will advise you initially on how much the work can cost. And then the master comes and paints the entire course of his work in stages. In addition, you can conclude a contract with them for the maintenance of your plumbing.
