"Had a backup a few days before and wanted to determine if it was a simple clog or cesspool related. They sent out a tech (Jimmy) the same day. He located both cesspools and walked me through my options. He was honest and patient, answering all my questions along the way."

"Jeff came and was very informative on the overall process and probably the best information I have received to date from anyone. He was very thorough and went thru the process he was performing step by step in a way I could understand. Looked at other causes to see if drain was clogged as week and cleaned up all the dirty areas. Would definitely recommend him to all neighbors and family. Great job Jeff. Thanks"

"I thought they did a great job; they were very professional and courteous, if there was anything I did not like was that the initial job was to unclog the main sewer line, but could not do it, they still charged me $275, in the past I only paid from $75 - $150 when they unclogged the line, they charged so much money for not unclogging, I think they should have bypast that charge, I did pay $9500, to replace the main sewer line and trap, which I'm ok with."

Customers say: Terrific value

"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

French Drains FAQs, answered by experts

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.

No. You should never pour old paint down a drain or sewer because it can clog pipes and pollute the environment. You must dispose of paint properly and safely. Different types of paint need to be disposed of in different ways—oil-based paints must be taken to a paint recycling center, while you can throw dried-out water- or latex-based paints in the garbage. 

Yes, chemical drain cleaners contain sulfuric acid and hydrochloric acid, both of which are not only dangerous to your health but also extremely caustic. Drain cleaners will corrode your pipes and could lead to destroyed drain lines, especially if the chemicals interact with the piping for long periods. Unfortunately, this extended interaction is likely if you’re dealing with a clog, as the drain cleaner will have just as much trouble as water does moving through your plumbing system.
