"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

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

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.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.
