"My sewage ejector pump in basement would not stop running and I was looking to replace it. I texted Dean two pictures of the pump, he was able to give me a quote over text and the price was quite reasonable. He received a new pump on 5/22/2023 and came over to my house. After opening up the old pump and checking, he told me that the only thing that is really broken is the check valve, the switch got stuck but is still functioning, and the pump itself works fine. I ended up asking him to only replace the check valve and the switch and this saved me about $1000 from the original plan. I appreciate Dean's honesty, professionalism, and a job well done."

Basement Waterproofing questions, answered by experts

Yes, you can over dehumidify your house. While you may prefer a dryer climate inside, the elimination of too much moisture in the air can lead to an extremely dry environment that can affect those with respiratory and skin issues. Strike a balance between eliminating excess moisture without making your home feel like a desert. Most modern thermostats show the humidity levels for guidance.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

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.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
