"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 ."

"I am extremely happy with with Wu Construction! From start to finish it has been a very pleasant experience. First, I send a frantic email after heavy rains to which I received a quick and reassuring reply - on the weekend! Next Greg came out to quote, provided a good price and was able to get the work scheduled for me on the spot for only a week later. Thanks Greg! Today the technicians arrived right on time, were very professional and did an amazing job. I kept peaking outside to see what was happening and I could tell they were executing the work with great care and attention. The quality of the work exceeded my expectations. Also it was discovered midday that more work was needed than originally thought when one of my downspouts was unearthed full of roots. I appreciate that they were able to accommodate the additional work and still complete everything in one day!"

"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!"

"Upon discovering the source of the leak, Duga Construction provided me with options. I finally chose a new, long-lasting and properly installed membrane as the best overall solution. Duga was great to work with throughout the process!"

Basement Waterproofing questions, answered by experts

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

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.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.
