"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"I've worked with Donnie on several properties to evaluate structural issues, he's always been very professional and thorough with his inspections and identification of structural issues. Recently I had him perform a structural repair on one of my properties that had a tight deadline due to insurance and he got it done without an issue. I would recommend Donnie and Upstate Structural Repair for any structural repairs or consultation!"

"Ethical plumbing did a fantastic job on the customer service side and the repair side. Alisha, the rep who contacted me on a Friday evening almost immediately after starting my search was pleasant and efficient. She made it possible for me to get service the next day. Michael showed up as scheduled Saturday morning for what I thought was just going to be an estimate but to my surprise was able to complete the job that day! And this wasnâ t an easy undertaking. It Involved digging, cutting lines, valve replacement for a leak behind the city meter. These guys are the real deal! I thought the price was a bit higher than I thought it may be, but the value received made me comfortable with it. Same day service, done professionally. I wholeheartedly recommend Ethical plumbing.

"My dealings with Chris were very professional and the Company's willingness to perform crawl space remediation on short notice was superb. The individuals performing the remediation work did a great job and were very hard workers putting in many hours to complete the job on a timely basis. They also did a great job at cleaning up behind themselves and leaving everything exactly as it was found. I would highly recommend this company to anyone needing the services they provide."

Basement Waterproofing questions, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.
