"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

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

The type of stormwater drainage system you need depends on your area’s storm severity and frequency. Your property’s location should also be considered, including the surrounding soil type, nearest roads, existing drainage systems, and slopes and hills. Your property’s structure, such as decks, walkways, crawl spaces, and foundation, also affects what drainage system will work the best.

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.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.
