Q: Does homeowners insurance cover the cost of slab leaks?

• <div><p>Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.</p></div>

Q: Is it worth putting a dehumidifier in a crawl space?

• <div><p>Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you&rsquo;ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It&rsquo;s also wise to purchase one with a self-draining feature. Otherwise, you&rsquo;ll need to climb into the crawl space to empty the dehumidifier.</p></div>

Q: How can I prevent mold after water damage?

• <div><p>Mold and other fungi love moisture, so the best way to prevent <a href="https://www.angi.com/articles/6-steps-prevent-carpet-mold-after-water-damage.htm">mold growth after water damage</a> is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.</p></div>

Q: Can I convert a basement into a game room, and what are the challenges?

• <div><p>Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.</p></div>

Q: How do I get rid of moisture under my elevated deck?

• <div><p>If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.</p></div>
