Q: What if there is standing liquid on my concrete?

• <div>If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.</div>

Q: Can you seal a foundation yourself?

• <div>While it&rsquo;s possible to seal a foundation yourself, it&rsquo;s not recommended, as it&rsquo;s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a <a href="https://www.angi.com/nearme/foundation-repair/">foundation repair professional near you</a> to see what the job will cost. </div>

Q: What are the alternatives to a traditional gutter system?

• <div>While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.Common alternatives include:<ul><li>Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.</li><li>Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.</li><li>Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.</li><li>French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.</li><li>Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.</li></ul>It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.</div>

Q: How hard is it to add a basement to an existing house?

• <div>The difficulty of adding a basement to an existing house can vary depending on the house&rsquo;s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you&rsquo;ll need to enlist professional help for this project.</div>

"we had concrete pads added after home construction. One pad had a 2 inch settlement on one corner. Complicating this was a stone wall sitting atop the pad. Excellent restoration was done by Groundworks From Bozeman. After a thorough evaluation by Ben, Chelsea and Tyler were prompt, educational and successful.
