The homes in San Ramon are surrounded by the roller coaster Contra Costa Valley and the ridges of Mount Diablo, and are faced with an invisible yet perennial threat, water. The tight clay soil and hilly lots of the region, as well as unpredictable winter rainfall make the drainage one of the most significant (and ignored) aspects of home service. A small puddle or patch of dampness can run out of control to foundation cracks, leaks in basement or erosion on the landscape just to mention but a few.
We offer professional drainage services in San Ramon, CA, which are dependent on the topography and the soil dynamics of the city. Water motion under and around your home is inspected, designed and installed. Since the art of draining and sump pumping in modern France, to yard regrading to the dot, all the systems that we construct are designed to save your house in the most silent and efficient way possible over decades.

Any drainage solution begins with the problem understanding. Our inspection of your property locates the movement of water within the site and its trouble-causing areas. We seek imbalances in grading, gutter run off routes and concealed point of collection which can contribute to the stress on the foundation.
It is by early capture of such warning signs that we can make corresponding cost effective corrections prior to the occurrence of leaks or any soil movement. Easier said than done is certain preventive drainage work as compared to having to fix the damage.
San Ramon is especially susceptible to drainage issues, which is caused by the steepness of the hillsides and thick soil. The most common problems that we face are:
Stagnant ponds that kill grass and breed insects.
These are the cracks that result due to water pressure acting against the basement walls.
Topsoil and landscaping runoff.
clogged or inadequately large systems that drive water away in the direction of the house.
Stagnant water that promotes the growth of molds.

It is possible to renovate your drainage system to enhance functionality and home value. The best advances that we can offer to the homes in San Ramon are:
These improvements provide absolute control of water flow – roof to soil.
Speed and accuracy are important when bad drainage begins to occur in your premises. Such marks as standing water, uneven soil, cracks around the walls of the basement indicate that water is already where it should not be.
We work out custom repair projections of their homes: could be installation of French drains, or redirected downspouts, or a re-shaping the soil near your foundation. Our systems become invisible as soon as they are installed and ensure your home stays dry and stable throughout every season of the storm.
Steady, well-organized repair service focused on structural safety and durability.
After noticing doors sticking and cracks in our drywall here in Warm Springs, we called for a foundation inspection. The team was incredibly thorough, using laser levels to measure settling and explaining everything in plain terms.
Nisan was very helpful on guiding me via the permit process for earthquake retrofit. Work was executed quickly. Thanks
We were very happy with the results of our inspection with Ryan! He explained the settling in homes and what things we should look for, and was very professional, friendly, and efficient. Thanks!
Had a great experience working with Kyndell from Golden Bay Foundation Builders. I recently purchased the home and was looking for help with earthquake retrofitting options. He inspected my foundation carefully and determined that past bolting was likely adequate. He had suggestions about monitoring the foundation. He was very thoughtful and detailed in his approach, and worked to determine what was best for the home. In this case, that meant no need for additional work now. But if I need any additional assistance in the future, will be calling him again.
We needed crawl space repairs due to pests and moisture damage. They sealed it up, reinforced the beams, and added vapor barriersnow it’s dry and structurally sound. Excellent service from start to finish!
