Get matched with top basement waterproofing pros in Dundas, MN

Q: What is the best ventilation for a crawl space?

• <div><p>The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper <a href="https://www.angi.com/articles/your-crawl-space-built-todays-standards.htm">crawl space code requirements</a> done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs. </p></div>

Q: How long does it take for water to cause structural damage?

• <div><p>Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they&rsquo;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.</p></div>

Q: Is water coming up from the floor an emergency?

• <div><p>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 <a href="https://www.angi.com/articles/will-water-damage-concrete.htm">water-damaged concrete</a>.</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: Is it better to have a vented or sealed crawl space?

• <div><p>It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it&rsquo;s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible. </p></div>
