"Removed old fiberglass insulation that at one time was rodent infested. Removed old plastic ground cover sheeting. Installed new ground cover black plastic sheeting and new fiberglass insulation. This was in the basement crawl space in my 9-unit apartment building. Very satisfied with the work - they were very responsive to some follow up work - would definitely recommend ."

"Greg was prompt in coming to view what needed to be done and quickly assessed the best way to prevent storm water from entering our garage. He gave me a very fair bid and stuck to it. His work crew, Young and Jasper, were here right on time and worked hard all day until the job was completed. They didn't waste a minute, doing exactly what they said they would do. Their final product was excellent, much better than what I envisioned it would look like. Their work will resolve our problem (now I just have to keep things clean). Thank you for a job well done! I certainly will hire Wu Construction again if I need any services they provide."

"I had a LOT of questions and Ryan, the owner, responded quickly to each email. The work crew were all polite, quiet, and all-around good people. The price was reasonable compared to comps, and the job was finished when they said it would be. We've had some torrential rains since and not a drop has gotten into my basement!"

Basement Waterproofing questions, answered by experts

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

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 most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

To maintain an outdoor structure, perform regular inspections for damage, leaks, and weak joints. Clean the structure regularly, treat or repaint wood surfaces for weather resistance, and reinforce any weak joints to prevent deterioration and ensure its longevity.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.
