They go above and beyond."

"Bill, his son Derrick and assistant Victor did a great job assessing and fixing our leaking, damp basement. They installed a dehumidifier, waterproofed walls and floors in unfinished closets and found and rectified overflowing downspout that caused a basement flood during the last big rainstorms. Very professional, helpful and friendly. I highly recommend them."

"Had a backup a few days before and wanted to determine if it was a simple clog or cesspool related. They sent out a tech (Jimmy) the same day. He located both cesspools and walked me through my options. He was honest and patient, answering all my questions along the way."

"Lorenzo and his team did an excellent job of building a replacement concrete footing wall to support our stairs going down to the water. They did an excellent job under tough conditions. They were both on time and very neat."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

Basement Waterproofing questions, answered by experts

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. 

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road.
