Called early Monday morning for a blocked sewer system (stopped up Sunday afternoon, with water backing up into the bathroom). Called to avoid an 'emergency' response price. No answer when I called at 7:30 am, left voice message, and figured if I had not heard back by 8:30, I'd try someone else. They called back at about 8:15, we spoke the details, and they said they were one a big job but would have someone come out 'within the hour' to check it out. 15 minutes later, two trucks pull up, and they immediately started checking things out. Determined there was no exterior clean-out set up, but discovered the seal on the guest toilet was compromised, so it would have to be replaced. They said they could snake it from there. So, we laid down protective covering for the bathroom and hallway from the door to the bathroom, then one left saying from here it was a 1-man job, and he would only be standing around watching. Within the hour, the remaining tech pulled the toilet, tested the system only to discover there was no longer a blockage. We tested all the drains/toilets and created a large outflow of water, but no draining problem. We concluded the blockage must have been temporary, and everything was now clear. He replaced the seal, caulked around all the toilets (the were never caulked originally), cleaned up, snake out the shower drains just to ensure there was no buildup of hair, and called it good. Overall charges...just for pulling the toilet, resetting the seal and resecuring. Very reasonable price. They filled me in on what would be the expected costs to install an external clean-out, but no pressure. Said it was most likely a temporary blockage, told me what to watch for just in case, and gave me contact information if something else happened. Been 3 weeks, everything is fine, and we're pleased as punch.
