"Zero stars if it were possible. Harry M came to my home and quoted me 200 dollars and cash was the only payment option he would accept. He came that Saturday and did a horrible job. He used my mower and it’s not working properly now. He didn’t have a working weed wacker and asked for my personal one. He left so many areas undone and I he did report he would come back to finish the job. This never happened; he kept saying he had me scheduled but forgot to tell me. A crew was supposed to come two Saturdays ago and this never happened. He does not respond to text messages. Most importantly, he asked to come to my house to BBQ and to date me. I have text messages to prove this. Even after I declined, he didn’t not understand no after being told several times. There’s a review on another site that doesn’t remove negative feedback and he called that person cursing them out and verbally threatening them. If he does this to me, I will immediately press charges. I’m reporting this fraud anywhere I can until I get my money back from this fraud."

"The job inside was done. However the drainage put in outside has turned our yard into a swimming pool. We once had a pipe draining to the creek and this was a perfect solution to the rains/weather. These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

"We paid close to $20,000 to BQ Basements to completely waterproof our basement. We still get water and they told us we need another sump pump installed at over $2,000. They guaranteed we would not get water after installation. Be aware they do not stand behind their work or honor warranties."

French Drains questions, answered by experts

This depends on the location of the blockage. If the blockage is in your home’s system, anywhere in the system, it is your responsibility as a homeowner. Blockages seldom happen because of items or buildup coming from the city, which means it originates in the home. It becomes the city’s responsibility at the exact point your home’s line distributes waste into the city’s system. The exception is if the problem in your home damages the city lines.  

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.

Yes, drains are one common entry point for water bugs. However, water bugs may enter your home through various locations including doors, windows, pipes, and vents. Water bugs are drawn to the dark and moist atmosphere drains provide, and can easily find their way into your home through sewer drain pipes. You can stop water bugs from entering through drains by regularly cleaning your drains and repairing faulty drainage systems.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.
