• <div><p>Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile.

Q: Is a walkout basement below grade?

• <div><p>A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can&rsquo;t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it&rsquo;s legal to do so.</p></div>

Q: Is a moisture or vapor barrier necessary?

• <div><p>A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.</p></div>

Q: What methods are used for waterproofing basements or crawlspaces?

• <div><p>Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.</p></div>

Miguel was a consummate professional who saved our roof right before a rain storm. He came out at night to beat the storm and quickly and expertly patched three holes. He was very thorough and his price could not be beat! HIRE THIS MAN! You won't be sorry! Thank you Miguel and Aguilera...

Michael was great! The work was actually for a shed installation so we could put our washer dryer outside our house and he did the plumbing, sewer, and electrical and carpentry all himself. It is hard to find someone that can do everything like this and to do it well. He is also very friendly...
