"We had excellent experience with Alpha Structural. Charlie Rosenkranz came to see the property and advice. He checked the structures all around and looked in the basement as far as possible beyond the ducts that were filling up the space and would require tunneling to get to some areas under the building. Communication was excellent. He's knowledgeable and experienced. We appreciated his professional no pressure approach and answering our questions. The front main duplex needed Seismic Retrofit; it wasn't bolted and had cripple walls. There were suspect areas in the foundations that would have to be tested when bolting, to see if the concrete is in good shape. After we agreed to their proposal have the work done we scheduled a range date. They had to submit to the city plans for a permit to do the work and wait for the permit to be issued. While doing the retrofit we found out that the foundation in the front corner was damaged and that the building has sunken and was not level at that corner. Charlie worked out the details and bid for the additional work of Partial Foundation Replacement, Posts/piers, and Jack Lift the corner to level it. He explained the details and what's involved to my satisfaction. Alpha obtained the permit for the work and proceeded. The work crew did excellent work. Jose Morales was the Project Supervisor. They completed the work at a good pace, including the delay for the additional work permit, without complications or complaints from the neighbors. The place was left clean. The work was approved in the inspection which they requested and scheduled with the city. The communication with everyone at the office was also very good. We're very pleased with the experience."

"We had a second story deck that was leaking water into the garage. We got 4 companies to come and give us a quote.  Two of them were cheaper but they seemed as puzzled as we were about what to do and could not guarantee from future problems. The other company suggested rebuilding the entire deck and was way out of budget. Ryan from Monarch Custom Coatings came with a sample that had several layers to waterproof the deck - we were very impressed that he was very knowledgeable and has a lot of experience with this type of work. He and his crew worked very hard, always professional, prompt, courteous, and our deck looks amazing now. We were so happy with them that we hired them again to redo the garage floors. We have had bad experiences in the past with contractors, so we know that finding a good, reliable, and honest one is very hard and rare. We highly recommend Monarch Custom Coatings!"

Basement Waterproofing questions, answered by experts

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

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.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.
