"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."

"These guys were awesome!! If you need foundation work, call them first. I have a raised foundation and it was off by 3 in. in some area's. I went with this company because they do not use contractors or sub-contractors. Everything is done by the company! I had one window break and they called me immediately about it, cleaned it up and got the plywood to cover the opening. When they gave me the quote I didn't quite have the money. I called them apprx 10 mos later to give the go ahead with the work. By that time the prices had gone up ALOT by 10K. But they honered the 1st quote because it was under a year old. And a good warranty!!"

"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

In Orange, homes with post-and-beam or slab-on-grade foundations—common in mid-century neighborhoods—often present unique waterproofing challenges. Watch for split-level layouts, hillside construction, or homes with partial basements, as these can complicate moisture control. Signs like diagonal foundation cracks, shifting soil near the foundation, or mature landscaping close to exterior walls may indicate the need for specialized foundation waterproofing solutions tailored to Orange’s soil and climate.

Helpful?

In Orange, be wary of contractors who overlook hillside grading, local soil movement, or do not mention necessary permits for foundation waterproofing. Avoid quotes that lack details on moisture control methods or fail to address Orange’s seasonal weather patterns. Watch for missing warranties, no references from local projects, or requests for full payment upfront. A reputable professional should understand the city’s building codes and unique climate challenges.

Helpful?

When planning basement waterproofing in Orange, consider the area’s seismic activity, high water table in certain neighborhoods, and local water use restrictions. Check if your property is in a hillside zone, as this affects drainage design. Be mindful of city permit requirements and any HOA guidelines. Also, consider how mature native plants or irrigation systems could impact foundation moisture and the effectiveness of waterproofing measures.

Helpful?

In Orange, basement waterproofing maintenance involves more than standard upkeep. Besides cleaning gutters and downspouts before the rainy season, regularly check French drains and sump pumps for debris, especially after Santa Ana wind events. Inspect for new efflorescence or moisture along walls, and monitor humidity during hot, dry summers. Adjust grading as needed, since shifting soils in Orange can affect drainage and the long-term effectiveness of waterproofing systems.

Helpful?

As a new homeowner in Orange, start with a professional evaluation focused on foundation waterproofing and drainage. Address any visible leaks, seal minor cracks, and improve grading to direct water away from the home. Before the rainy season, ensure gutters and downspouts are clear. Within your first year, consider installing a sump pump or French drain if needed, and monitor for signs of moisture or mold during hot, dry months.
