"It went fantastic. Drain's Inc responded to my call and were at my residence in a very timely fashion.. They preceeded to rod and unclog the drain. It now looks like a cyclone of water decending down the drain. I would highly recommend Drain's Inc for you plumbing needs.

"I live in MI, but had to get a toilet replaced at my mother's home in Burlington, WI. Not happy with the estimate I got from her regular plumber, I posted the job on Networx.com, a Home Advisor partner. Ryan Collins (Collins Sanitary, LLC) was on the phone within 10 minutes offering to do the job. Since I was in town only briefly, I needed to get the job done quickly. After checking his credentials (Ryan is a Master Plumber), I called back and was able to schedule the work for the very next day. Ryan arrived when he said he would, completed the work quickly and efficiently, cleaned up the work area, and charged a very fair price. (He installed a toilet that my husband was able to buy on sale at Menard's, and hauled away the old one.) I couldn't have been more pleased. Not only would I recommend Collins Sanitary to others, I've also advised my mother to permanently switch plumbers!"

"This is the first time I've hired a plumber, after owning my house for 44 years. My main sewer line was clogged very bad and our one toilet and drains no longer worked. This happened late on a Friday afternoon. so I called Mike Wagner, described my problem and he said he could check out the problem at 9:30 on Saturday morning. He told me not to use the toilet or drains overnight, since the sewer water would probably drain down. He arrived on time Saturday morning, assessed the problem (the water did drain down, as he said it would) and indicated he wanted to add a PVC clean-out behind my house and then rod out the sewer line to the street. He gave me a verbal cost estimate and said he could have a crew available to do the work on Sunday morning. He said we could use the toilet and drains sparingly until the work was completed. On Sunday morning, Mike and two helpers arrived to do the work at 9AM, he gave me a written quote, which I signed and they had everything done by noon. I paid for the work with a check, since he doesn't accept credit cards. Everything was completed quickly and professionally. The price I paid seemed a little bit higher than I had expected, but considering the work was completed quickly on the weekend, I can't complain. I was very satisfied with work that they did and Mike included a warranty, in case anything should go wrong, he would stand behind his work."

"Two problems: one, a leaky toilet. The toilet is very old. One prior plumber refused to work on it, said it was too old to fix. Dynamic had it fixed in about 45 minutes. The second problem is ongoing. I have a drain problem in a basement floor drain that takes water from a washer via a sink. They rodded in every direction but it still drains slow. The plumber stuck with the job for five hours trying to resolve it. Unfortunately it looks like we're going to have to do some major repairs (jackhammer the concrete floor and replace the pipes). However I give them credit for going above and beyond to try to solve the problem."

"Austin and his crew were great. The Real Seal staff is professional, courteous and on time. They gave accurate estimates, time frames and provided real solutions. Replacing the sump pit created a mess as they basically had to dig a new pit. The crew did a great job cleaning up. By the time the crew was gone you would have never known they were there. We have used The Real Seal in the past when we needed an additional sump pit and an interior drain tile in the opposite side of the house. We had had minor water seepage issues for many years and was unable to determine the cause. Austin took the time to work the issues, determined the cause and came up with a great solution. We have had no issues and many heavy rains in the past couple of years since the work was completed. Without the work done by The Real Seal we would have definitely had water issues. We have used The Real Seal in the past, and if we have issues that they work on, we would definitely use them in the future."

"I got a referral from a friend of mine. When I had a plumbing problem, he said. These guys were very reasonable and very timely. I very much agree with that. They came out on a saturday, replaced all the drain pipes from my sink to my sewer outlet in record time and charge me a very fair price. I then had another project at another property. Joe came out, looked at it immediately told me what it would take to resolve the issues and we haven't done that project yet. But it's gonna be getting done soon. Great guy to work with, absolutely dedicated to his craft."

"My existing window well had pulled back from the homes foundation over the past 20 years, allowing water and sediment to enter the well. Sediment would plug the drain causing water to build up and create an aquarium in the window well. You pass waterproofing installed a new window well and securely fastened it to the cement foundation. They carefully removed the previous window well and took care not to brutalize the surrounding landscape. Completely satisfied with their work"

French Drains FAQs, answered by experts

Yes—your local septic company can clean your septic leach lines with a sewer jetter, a device that pumps high-pressure water through the lines to blast out any clogs and scum buildup. Unless there’s a clog or blockage in the lines, however, you do not need to perform this maintenance regularly. Do not attempt to clean your own leach lines, as you could easily damage them, leading to very costly repairs.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

Yes, frozen pipes can prevent a toilet from working correctly. If the pipes are frozen, water cannot flow, which means your toilet tank won't be able to refill after a flush. This will prevent the toilet from flushing again. Depending on which lines are frozen, the ice can also block the drain pipe, preventing water from flushing away.

As a temporary workaround, you can manually add water to the tank for each flush. To clear a frozen drain pipe, you can try filling the toilet bowl or tank with warm water and flushing to help thaw the ice. However, the best long-term solution is to unfreeze the pipes to get your toilet back in working order.

A good option for opening up and cleaning a sink drain is to use a ¼ cup of baking soda and 1 cup of white vinegar, along with a rubber stopper to cover the drain while those materials work their magic. After about 15 minutes, you can flush the drain with hot water. In many cases, these materials can scrub out minor clogs and get the drain working properly again. If the issue persists, call in a plumber near you to get the problem permanently fixed.
