"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"Robert and his crew did a great job installing a concrete walk in my side yard. They had some challenges working around our existing irrigation valves and pipes, but they took the extra time to do it right. After installing the concrete Robert found an area which was not draining fully and he put in extra time and effort to fix the problem area. Robert communicated with us during the project and was very professional. I would recommend Robert Garcia Concrete!"

"I recently had the pleasure of working with Anthony Fankhauser from Rooter Er & Plumbing, and I can confidently say that he is the most professional plumber I have ever encountered. Our search for a reliable plumber began about six weeks ago when Anthony came over to provide us with a free estimate for some work needed in our home. From the start, he impressed us with his prompt response to our request on Angie's List, arriving the same day and offering valuable tips to make our shower remodel efficient and cost-effective. Throughout our interactions with various plumbers, Anthony stood out by taking the time to truly understand our needs and how he could assist us best. Despite the initial consultation not resulting in immediate work, Anthony remained responsive and proactive. Fast forward six weeks, and he was once again quick to reply, reaffirming our confidence in his professionalism. On the day of the job, Anthony arrived on time and efficiently installed our new shower faucet, recommended the best option for our budget, and set the drain in record time, coordinating seamlessly with another contractor working on the floor. Not only did he go above and beyond by addressing additional plumbing issues in our home, such as resealing a leaking toilet tank and replacing faucets, but he also made trips to Home Depot on our behalf without any extra charge. Anthony's dedication to meeting our needs, even outside regular working hours, sets him apart from other contractors we've worked with during our home remodeling project. His attention to detail, professionalism, and unwavering commitment to quality work make him a standout professional in his field. I am typically critical when it comes to service providers, but I cannot fault Anthony in any way. His integrity, work ethic, and genuine care for his clients make him a truly exceptional plumber. If you are in need of a reliable plumber, I highly recommend reaching out to Anthony Fankhauser at Rooter Er & Plumbing. Whether you are in South County or in areas like Marietta, you can trust that you will receive top-notch service and expertise. Thank you, Anthony, for your outstanding work and for exceeding our expectations."

Foundation Drain Installation FAQs, answered by experts

Installing a sump pump takes a bit of know-how, but it is possible to do it yourself. You’ll need to familiarize yourself with details like where sump pump water goes to avoid creating new flooding risks. If you’re doing the work yourself, it’s recommended to bring in a pro for a quick inspection afterward so you can be sure your home is protected from any water damage concerns.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

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.

There are a few possible sump pump drainage locations, including a neighborhood storm drain, into a creek or pond, or underground. Don’t let your sump pump water go into your sewer or septic system. Ideally, your drainage spot should be on a downhill slope that’s at least 10 to 20 feet away from your home’s foundation. Before choosing a location, check your local codes and regulations.

If the time has come to install a French drain in your yard, basement, or crawl space, there's a solid chance you've been battling water damage—or the threat of water damage—around these areas. Thankfully, proper drainage should allow you to redesign these areas of your home without the fear of being inundated during the next storm. If you've had to remove a portion of your lawn for an exterior French or curtain drain, consider reseeding your lawn to patch up the spot. You can also take this opportunity to enhance your foundation waterproofing methods or even start thinking about finishing your basement .
