If a plumber needs to do major repairs to your house, the work could call for a permit. You'll want this since a permit provides added assurance that the work is done correctly. Having this added measure in place means an inspector will check the work your contractor or plumber does to ensure he or she did the job correctly. If you ever plan on putting your house or commercial building on the market, a real estate agent and prospective buyers will also want to check any large work you did to make sure it was done properly.
I want to thank Luis and Charlie's Rooter Service for Outstanding customer service. Luis came out for a clogged shower and later to find out that the cause was my main sewer line. He was honest on the cost and what needed to be done, Luis gave me options to make my decision easy. He was polite and professional, if you need quality work I would recommend Luis and Charlie's! Thank you Luis
