"Had a flooding basement and Collins sent out Blake and Adam right away and they did a really great job getting the drains unclogged and running a camera through and taking the time to show me the condition of the whole drain pipe. Really professional and lowest price of all the bids I received, definitely recommend!"

"Out of the three basement waterproofing experts we called to offer solutions after getting a lot of water in the basement of our 1925 home, Joe at The Real Seal was the only one who seemed to take serious time in investigating the cause. He even came back a second time after we got more water in another spot to see what could be causing it and what a cost-effective solution might be. On top of that, the price was right! We never ever felt pressured into committing to the work, and they seemed confident in their skills to get the job done. Our partial interior drain tile job was finished in two days. While we can't yet vouch for the drain tile's efficacy since we haven't gotten a large spring rain yet and we're still in the process of refinishing our basement after it was demoed for this work, we expect we'll have a dry basement!"

"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

Regrading your yard can often fix drainage problems. You can also try aerating the lawn to encourage better drainage or install a new drainage system to prevent water from pooling in certain areas.

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.

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

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.
