"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 pride our company on reliability, great communication, integrity, and quality work. We strongly believe in giving our absolute best in all of our projects no matter how big or small. We are experts in our trade and will always keep you educated on your particular task or project. We look forward to earning your business!

"They did removal of old broken-down encapsulation, redid, made air-tight, waterproofed, mold and mildew treatment, French drains on two sides, drained cinder blocks, filled holes left from previous drains and vents, installed new sump pump and dug in, leveled-the slanted area for proper drainage, installed new exterior drain, relieved 4" of standing water and established proper flow. PROFESSIONALS TO THE MAX!!! It's gorgeous and clean and brilliantly done. I can't say enough good stuff about Patrick and his crew! Even after traipsing in and out with wet, muddy old encapsulation materials and debris in the rain, they left my place in sparkling condition -- NO evidence of them ever having been there! No cig stubs (they don't smoke), no old drink bottles, not even a cleaning cloth. Swept, washed drive, vac'ed ramp, washed entry ladder. VERY knowledgeable. Not my first encapsulation and sump pump situation but by far THE BEST. Quality materials, good work ethic, a pleasure!"

"Eric and his crew tackled a long-standing drainage problem in the basement of our 1932 Craftsman bungalow. 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."

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.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.
