"The French drain is working well but the rest is marginal. We have some water intrusion in an area that was supposed to be waterproofed, we do not have the molding installation for the downstairs flooring that was promised, and the dehumidifier has not rid the house of the mold smell, as was promised by Kevin, the sales guy. In addition the crew, and sales person, never noticed that the dehumidiifier and sump pump were installed in an area without an electric outlet, resulting in yet another expensive job to add to the $14,000 bill from JW. Also the billing practices with this job were shaky at best - just now, five months after the job was fully paid for, we received a mysterious bill for roughly $350 supposedly for some error that was recently discovered! So overall most of the job got done satisfactorily but it was a far cry from the exemplary work and service I received from John's several years ago when our encapsulation system was installed. I can only give an overall rating of OK since I know there must be better out there."

"These guys were great. Always answered my calls, texts in a timely manner, performed all the work we had discussed and then some ( went the extra mile when I asked to get us more plants at the last minute)! My experience with other landscapers were they never returned calls and seemed to have difficulty finding the plants we wanted - Sherpa Landscaping came through and did an excellent job - highly recommend!!!"

French Drains questions, answered by experts

Clearing typically takes 1-2 hours, depending on the blockage size and location.

Professional tools include drain snakes, hydro jets, cameras for line inspection, and enzymatic or chemical cleaners for dissolution.

Most blockages can be cleared in 1-3 hours, but severe issues may take longer.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.
