"Kevin Gardner & his helper Sam were really nice respectful fellows. I only gave then 4.5 stars on work quality because an auger cable broke and they had to fish it out. I gave them 5 stars on customer service for a number of reasons, not the least of which was there was no b.s. about the broken cable situation. Past that, they both spoke to me with knowledge and humor and answered all my questions as well as gave me valuable insight on how to deal with the issue going forward. Pricing of the job was clear from the get-go. I'll be calling Kevin again. One other thing: I was very frustrated with my situation after working on it for 8.5 hours on a Friday, I went to Home Advisor put in my info and got a text from Gardner in 10 minutes requesting that I call. Kevin Garner answered, I ran through the litany of my issues, Kevin correctly diagnosed the problem, as we found out later, and we agreed on the money for the camera work right then and there. We also made an appointment for the next morning, a Saturday, between 10-11am. They were at my door at 10. It was raining fairly hard and I'm not sure I, if I were them, would have been on time as they had been to a previous job in some mud field. They were nice about my not being quite ready to show them the issue (at an adjacent building) and gave me the 5 minutes I needed to 'dress for success' :), without any comment or complaint at all. In fact they were complimentary about my previous day's work of trying to resolve the problem with just a old style manual feed auger that I worked for 8.5 hours. They told me that they wouldn't have felt like getting out of the sack either, after all that. Like I implied: Decent, nice and respectful people. I'll be hiring this outfit again!"

"We highly recommend AFS for waterproofing a crawlspace. AFS encapsulated our crawlspace on our new construction home and installed a sump pump and dehumidifier in the crawlspace. The install crew (Tim - Foreman, Trent, CJ and John) was very prompt, courteous and professional. They explained everything about their work, and thoroughly cleaned up the worksite. Tim returned a few days later to finish up after our electrical outlets were installed and to make sure everything was working properly. Our salesman Reid was also excellent to work with. He explained everything in detail and answered all of our questions."

"Yes, the crew (Isaiah, Brian and Austin), were very professional and hardworking. They were fun to have around and they did a great job. They removed the original shims under the girders and carefully replaced them with steel shims. My house now sits on a better and more secure system. I would definitely recommend Thomas waterproofing."

"David recently came out for a periodic system inspection and promptly replaced a sump pump exit line valve out in the yard that had been damaged by a lawnmower. we discussed adding a backup to the sump pump, which I decided to do. Matthew was out in just a few days to take care of that installation. Everything went quickly and smoothly. These guys are pros."

Drain Pipe Installation FAQs, answered by experts

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Pouring drain cleaner down a vent pipe isn’t recommended. First of all, unlike a clog in a sink or bath caused by such material as soap scum build-up, toothpaste, and hair, clogs in a vent pipe are likely the result of debris from trees or even an animal stuck in the pipe. Drain cleaners won’t be able to eat through this kind of material. The cleaner will only become clogged in the vent with the debris, causing even more problems.

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.
