"Theron and Vince are some of the most reliable, efficient plumbers I know. They got me onto their schedule right away, showed up to give me an estimate looking very professional, and preformed excellent, clean work. I thought all plumbing companies were the same until I called Marathon Plumbing. I will be recommending Marathon to everyone I know from here on out. No one can beat their professionalism and honest work."

"Well. 1st plumber who looked at the system said shower valves needed to be replaced but that was a problem because there are no access panels. Chaub plummer advised valves were good quality and there was no need to replace. He replaced/installed new hardware and did a great job in a timely manner."

"Our sump pump quit working and we had a minor flood in our basement. Mountain Edge Plumbing came the same day and replaced the pump and made sure it was up and running consistently before they left. They were courteous and professional. We really appreciated their expertise and that they could even come the same day. Highly recommend!"

Basement Waterproofing questions, answered by experts

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

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.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.
