"Bob came out, looked over the situation, and told me that I needed French drains and a sump pump installed. He reviewed exactly what he planned to do, when he was available and gave me an estimate right then and there. I was impressed with his knowledge; it was obvious from our conversation that he was experienced and knew exactly how to fix our problem including reworking the gutters in addition to the drains and pump. We hired Bob and he and his crew were out early on the appointed day and worked tirelessly for two full days. I was very happy with their work and how spotless the basement and outside area were when they were finished. About two weeks later came hurricane Ida!! Montclair experience extensive flooding but our basement was dry!! Best money I ever spent!! I recommend them highly. Weather-Tite is an excellent company!"

"We had started to get water coming in from the foundation of our basement. Sean had come to our home to give us our best option and estimate of what work they would end up doing. Overall it seemed like the best choice, and sure enough, it was. We had french indoor drains installed in our basement, along with an updated sump pump with a battery backup incase of power outages. Ever since this was completed, we've had no issues, and our basement is fully dry. It only took a few days to complete, and they did a great overall job!"

"Robert first came out to my house to fix a really bad clogged drain in our kitchen. He also came when it was convenient for us after work for both myself and my wife. He guarantees his work for 30 days with a clogged drain, well he ended up coming back yesterday and he came when he said he would and he completely fixed the problem. he was very professional and honest and didn't charge me for coming back to fix the issue. I would recommend them to anyone with problems. Mike"

"Alex was very responsive and we made an appointment for him to look at our driveway to give us a quote. He understood our drainage issues immediately and explained thoroughly what needed to be done to fix it permanently barring any biblical deluge. Alex got back to us quickly with a written quote that was very reasonable. We have decided not to go ahead with this investment at this time, but when we are ready, Alex is our man. We highly recommend him for his knowledge, experience, and prompt response time."

"They were my third choice of contractors, but first two choices were booked up so I settled. I think I should have waited. Sam was affable and a bit aggressive with sales pitch but mostly returned calls in a timely manner. Work was adequate, but there were mistakes made - low spot on walkway that collects water next to foundation, crooked edges, uneven placement of some concrete. They left a mess, splattered concrete on house siding that required power-washing to remove; dirty greasy handprints on vinyl siding that needed scrubbing to remove, lots of gravel left on lawn; broken drain pipe, left forms on-site for over a week despite constant calls."

French Drains FAQs, answered by experts

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.

Drain pipes carry wastewater from sinks, toilets, showers, and other fixtures to the main sewer line. They’re typically located within the walls and floors and beneath a home’s foundation. Meanwhile, sewer pipes transport collected wastewater to a septic tank or a municipal sewer system.

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

Professionals use snakes, hydrojetting, or chemical cleaners to clear blockages effectively without damaging pipes.

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.
