I just looked at a house to purchase and the floor has what looks like a speed bump in the floor. When I checked the basement, it didn't look like it was caused by the floor being jacked up. What is the possible cause of this and what is it going to take to fix? The bump is slight but is noticeable.
Safety glasses are always a good idea to protect your eyes from splashes. Also, since the chemicals could be acids or bases, wearing gloves would be a good idea. One thing to always remember about cleaning solutions is: NEVER MIX two different kinds of solutions! Poisonous gases can be released in some cases. So, be safe and never mix different cleaning solutions.
Without seeing the job a price would be impossible to give, there are many different factors involved,,,,access to the leak, sometimes they're a bugger to get to,,,type of material used, PVC is cheaper than copper, in price and quality,,,amount of pipe being replaced,,,,,,etc. Figure whatever the hourly rate in your area is, times four to eight hours. The Faucet should be in the hourly rate since the plumber is already there, but some companies will charge a fixed rate on the faucet, which is usually higher than the hourly rate. If your water is still on and you're not in a rush, get some other bids. Reject the highest one, they're ripping you off, reject the lowest one, they're low balling you to get the job. The final price will be much higher..take one in the middle by a reputable company that's been around a while.
