"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results.

"I had a drain clog that was becoming a real headache, and Sewer Surgeons took care of it quickly and professionally. The technician was friendly, showed up on time, and explained what was going on without making it complicated. The price was fair, and there were no surprises. The whole process was made easy and overall I would recommend them to anybody in a heart beat."

"Mike the owner came by and gave me an estimate - as we progressed we found additional issues with my folks home that needed to be addressed. Mike and his team did a thorough and professional job. I truly appreciate all they did and all the help they provided to ensure that we got the issues at my parents home fixed and resolved and best of all the work is guaranteed and transferable to whomever the future owners will be! How can anyone ask for more... professional, friendly, polite and very respectful of the home and taking extra precautions not to track in the home, etc... and to always leave it better than they found it...  The crew was all wonderful and respectful as well ... really appreciated their work ethic!!!!

French Drains FAQs, answered by experts

No. You should dispose of all oil-based finishing products through a local hazardous waste program. Not only can oil-based finishes be hazardous for the environment if disposed of in the sink, but they can cause clogs in your pipes and stop up your drains. Most municipal garbage or waste disposal companies have a specific location or pick-up schedule for hazardous materials, so that’s your best bet to get rid of excess finishing products.

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. 

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

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.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
