"David did substantial work to repair foundation damage that was found during removal of a large tree that fell during the Helene storm. The foundation was bulging/collapsing inwards below grade to the interior of an earthen basement. The project needed more than a canned approach, which several other foundation contractors described that they could do. David explained several options for addressing the failure and stabilizing the foundation over the longer term. I was impressed by his thinking and very satisfied by the work. He was able to do the work in a timely fashion during a period when he was working on quite serious road and foundation repair projects resulting from Helene damage. I would absolutely hire him again."

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!"

Basement Waterproofing questions, answered by experts

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

While it’s possible to live in a damp basement, it’s usually not healthy to do so. Damp air affects your breathing, and it also promotes mold growth and pest infestation that can make living in a damp basement dangerous. You should plan to resolve any moisture issues and set up preventative measures before using your basement as a living space.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.

Water damage to a foundation often starts as a slow leak or water vapor problem that worsens over the course of months or even years. The speed at which foundation leaks worsen depends on a few factors, including your climate and location, the soil composition around your home, the foundation drainage system you have in place, if any, and the type of foundation you have. Even if you have a minor issue that’s slow to develop, it’s best to have a professional address the issue immediately.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
