"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"These guys were unbelievable! It sounds simple to run a water line from the street to the house but it wasn’t. Imagine almost 200 feet and hand dig uphill most of the way and across the yard. Now imagine having to go under a driveway, sidewalk and two concrete flower rails. Now add in they did it through one of the hottest heat waves Southern California had this year! I’m telling you these guys did it with sweat and a smile. Just unbelievable!"

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"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!"

"When we moved into our new home, the one area that needed improvement was the tub and shower. Both were original fiberglass that had seen better days, and both had old glass doors that were deteriorating around the edges. Steve came out and gave us an estimate, explaining exactly what he would do. He also gave us local contacts to buy the tile, and fixtures. Workers showed up on time, laid out dropcloths on the floor and cleaned up after themselves everyday. Work went right on schedule with the timeframe Steve said. Finished product went beyond are expectations."

Basement Waterproofing questions, answered by experts

For a San Clemente basement, keep a digital hygrometer, moisture meter, and UV flashlight to spot hidden dampness. Stock up on marine-grade caulk, hydraulic cement, and waterproof paint for quick repairs. Have a drain snake, wet/dry vacuum, and portable sump pump ready for drainage issues. Maintain dehumidifier filters, rust inhibitors, mold prevention sprays, gloves, and masks for routine maintenance and emergencies.

Helpful?

In San Clemente, confirm local permit and HOA guidelines before starting any foundation waterproofing. Choose contractors familiar with coastal moisture challenges, and schedule exterior work during the dry season for best results. Use salt-resistant, marine-grade materials and allow extra drying time due to humidity. Plan for equipment access, and monitor weather forecasts to adjust schedules if marine layers or rain are expected.

Helpful?

In San Clemente, begin each fall by checking foundation seals, looking for new cracks, and clearing debris from gutters and French drains before the rainy season. Test your sump pump and monitor humidity weekly in winter. In spring, inspect for water stains or mold, and schedule a professional review. Summer is ideal for applying new waterproof coatings and adjusting landscaping to direct runoff away.

Helpful?

For San Clemente homes, start with a thorough moisture control inspection to identify hidden leaks. Prioritize improving exterior grading, extending downspouts, and sealing foundation cracks with salt-resistant products. Waterproof window wells and install a high-capacity sump pump suited for coastal groundwater. Adding a dehumidifier and enhancing ventilation will help manage humidity unique to the area’s marine climate.

Helpful?

In San Clemente, if you notice new white efflorescence on basement walls, persistent musty smells after foggy mornings, or fresh cracks in the foundation, these could signal waterproofing failure. Watch for rust on anchors, bubbling paint, or damp patches during coastal rains. Water pooling near walls or slow-draining French drains also indicate your foundation waterproofing may need attention.
