Everyone affiliated with the company personified competence, conscientiousness and customer service. Have never had a better customer experience-could not recommend them any more highly."

"Excellent - Josh, Mark, and the team tore out 3 feet of concrete floor to replace the base of the stack pipe then worked their way up. Project took 2 days, first floor was completed and back on line the first day. Second floor and cleanup was done the second. 100 year old home so none of the old plumbing was easy to access. Very happy with results and with the professionalism of his team."

"Absolutely easy to work with, we had great communication throughout the project being completed. Took extra time due to myself wanting a special ordered trench drain to be used in front of the garage. We liked that they came out for a final inspection of the work that had been done and to see if we were happy with it before final payment to be made. We would hire again if needed. Good job installing the new house downspout drain pipe and trench drain."

"Wyatt did an awesome job. This was a major job. I had a water pipe break just under the house foundation. They initially believed it could be reached from the outside, but determined the break was just under the foundation. Because of this, they needed to break up the concrete floor in the basement at the outside wall. They carefully removed the floor molding and the wood boards before jackhammering a 2 foot by 1 foot hole at the edge of the floor at the outside wall. They were very neat and tidy. The broken pipe was fixed in less than a day. They then cleaned out many of the faucets and came back the next day to adust the water pressure and be sure all faucets were working properly. They kept us informed at all steps of the process and the cost was less than their estimate. We highly recommend Wyatt for your plumbing needs."

Basement Waterproofing questions, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

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.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.
