"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."

Drain Pipe Installation FAQs, answered by experts

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.
