"From my first Mount Valley Foundations evaluation appointment with Carlton Cisson to the construction team assigned to reconstructing and encapsulating my grusome crawl space foundation mess (Shaun Dixon, Alex Hernandez, Milton Martin and Dre Nesbitt) I experienced nothing but professionalism, positive & friendly demeanors, constant and thorough communication and a completed job above my expectations!

We'd had several estimates and options but They impressed us from the start with their solution to the problem and their professionalism. They were great communicators and kept us apprised of what they were doing every step of the way. Can't recommend them enough."

Hello my name is Fabian Quintin at a young age I began working as a Framer carpenter I spent 3 years framing until I decided I wanted to learn more trades in hopes of one day becoming the best builder in the nation so I began by working for a landscaping company and quickly memorized everything I needed to know and moved on to do the same with plumbing, masonry, concrete, drywall, painting, flooring, electrical, HVAC, insulation, foundation work and crawlspace maintenance, interior trim, fence installation or repair, siding and flashing, and finally demolition.

Foundation Repair questions, answered by experts

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.

Most homeowner’s insurance policies will cover the cost of slab leak repair that results from a natural disaster, like an earthquake or a severe flood, or from a tree falling on your home. Damage from frozen pipes in your slab is also typically covered. However, your policy is unlikely to cover the repair if an invading tree root causes the damage or if it’s a pinhole leak that results from corrosion. You should contact your insurance provider for a full run-down of what they cover.

Yes, foundation repairs are worth it if you have a significant problem or see signs that could worsen if not dealt with. If your foundation fails, your home can lose up to 20% of its value. Protecting your home from serious structural damage and avoiding more costly repairs later is well worth the money.

Yes, it is worth repairing concrete cracks. Concrete cracks are normal, and they can be hard to keep from appearing. However, it is worth repairing cracks in concrete for many reasons. For example, it’s possible to repair concrete to the point where the repair is almost invisible. Also, if the crack is left alone, it can become bigger and more expensive to fix over time.
