ABOUT CHIMNEYZ
Basement water problems rarely come from just one issue. Foundation cracks, poor drainage, groundwater, surface runoff, and water intrusion can all contribute to a wet basement—and simply sealing one visible leak may not solve the underlying problem.
Chimneyz was built to provide a more complete solution. We combine waterproofing, foundation knowledge, masonry expertise, and drainage solutions to identify where water is coming from and determine the right way to control it.
Instead of temporary fixes or guesswork, we focus on the source of the moisture, define a clear scope of work, and provide practical solutions designed to protect your basement and foundation for the long term.

FAQ
Get straightforward answers about basement leaks, waterproofing, drainage, sump pumps, moisture problems, and protecting your home from water intrusion.
How do I know if my basement needs waterproofing?
Common signs include water leaks, damp walls, standing water, musty odors, efflorescence, water stains, mold, and recurring moisture after heavy rain.
What causes a basement to leak?
Basement leaks can result from groundwater, foundation cracks, poor drainage, surface runoff, clogged or poorly positioned downspouts, hydrostatic pressure, and other pathways that allow water to reach the foundation.
Can you waterproof a basement that already has water coming in?
Yes. The first step is identifying where the water is entering and why. The appropriate solution may involve waterproofing, drainage, sealing, or a combination of methods.
Do I need an interior or exterior waterproofing system?
It depends on the source of the water, foundation condition, drainage around the property, accessibility, and project requirements. An inspection can help determine the appropriate approach.
Will basement waterproofing stop water from coming through foundation cracks?
Waterproofing and crack-sealing solutions can address certain sources of foundation water intrusion. The correct method depends on the location, condition, and cause of the crack.
Do I need a sump pump for my basement?
A sump pump may be appropriate when groundwater or collected drainage water needs to be removed from the basement. The need depends on your property’s drainage and water conditions.
How much does basement waterproofing cost?
The cost depends on the size of the basement, source of water, foundation condition, drainage requirements, accessibility, and type of waterproofing system needed.
How long does basement waterproofing take?
Project timelines vary depending on the waterproofing method, size of the affected area, accessibility, drainage work, and overall scope. We can provide a clearer timeline after inspection.
