"We had a very large, very long horizontal crack in our wall. Jacob W. was great. He answered all my husbands questions and worked his butt off. Along with Austin H. and Denzel K. The cleaned up everything when the job was done too. I would give them a 10/10 and would recommend them to anyone that needed foundation work done."

"The guys that came out to install my egress window were well trained and skilled. They got the job done in less than a day and cleaned up after themselves. The window passed township inspection and it appears as though it will handle water drainage appropriately. The supervisor addressed an issue that arose and resolved it quickly and professionally and to the satisfaction of all parties. I would recommend this company."

"We had a leak and drainage issues with our sump pump in the basement, leaks from the main pipe coking from the toilet, and our bathroom sinks would not drain. Jason and his Plumbing 911 team quickly fixed the issues in a professional and expedient manner. Truly grateful. Will hire again."

"Excellent. This experience was the best I have had hiring outside help. After it was installed, I had some concerns and asked Aaron to come by. He came over on a Friday evening and to my surprise, agreed and quickly went above and beyond to remedy the situation. He was understanding and agreed with my concerns. Later I was worried about a sound I was hearing coming from the sump pump. He came up on a Sunday and turned out it was my old pump (not the new one they had installed) that was making the noise. He removed it and clearly explained why it was making the noise. The perimeter drain, pump, and dry well that they installed have all worked great since the installation, which was nearly 9 months ago now. It was very clear making sure a job was completed well and with integrity was important to him. It was comforting to know I was working with a company who valued customer service and doing a job well. Their prices were more reasonable than the 3 other companies I had estimates from. I would definitely use them if needed in the future."

French Drains FAQs, answered by experts

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. 

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.
