Q: What are signs that I need to waterproof my basement?

• <div><p>Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:</p><ul><li><p>Water in your basement, including damp walls or puddles on the floor</p></li><li><p>Mold spots in your basement</p></li><li><p>Musty smells or odors</p></li><li><p>Warped doors or walls</p></li><li><p>Cracks in walls</p></li><li><p>Insect issues, such as cockroaches and termites</p></li></ul><p></p></div>

Q: Can water leak through window frames?

• <div><p>Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile. </p></div>

Q: Should I pick a topical or a penetrating sealer for my project?

• <div><p>Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.</p></div>

Q: Is sealing a foundation ever not recommended?

• <div><p>In some circumstances, <a href="https://www.angi.com/articles/foundation-refacing.htm">foundation refacing</a> or repair may be a better option for your home than sealing a foundation. It&rsquo;s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it&rsquo;s a good idea to get a professional opinion so you can avoid bigger problems down the road. </p></div>

Q: What are the downsides of a wet room?

• <div><p>There are a few <a href="https://www.angi.com/articles/wet-room-offers-versatile-bathroom-design.htm">downsides to a wet room</a>, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.</p></div>

Basement Waterproofing questions, answered by experts

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed.
