"They did exactly what they said. After looking at the basement mudjacking, I noticed that they could have easily done some work to get their recently re-leveled floor to match with the rest of what was around the section they touched. Good work, but no extra effort."

"Jordan was awesome! He initially sent one of his guys out to check for some gurgling and sediment in our plumbing in the basement. They took a good look and found some grading issues with our pipes. Jordan followed up with me after and then committed to coming out himself to determine options. Throughout it all he was very communicative and extremely knowledgeable. We discussed some options and moved forward with the one that made the most sense. The issue was addressed and Jordan followed up later on to make sure everything was still good. Highly recommend Jordan and team dr.drain!"

Basement Waterproofing questions, answered by experts

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.
