"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

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

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.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

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.
