"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!"

"Roger and his crew of Manuel, Carlos and Josias did everything we asked for and more. Roger answered all of our questions, kept us informed on the status of the project and managed the project extremely well. We definitely made the right decision having Groundworks do our project."

"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!"

Basement Waterproofing questions, answered by experts

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.

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, 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?

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, 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.
