A BIG thanks to Ryan and his crew for doing an excellent job doing the Earthquake Brace & Boldt at my parent's house. Easy to work with from the beginning to the end and completed in a timely manner. Also, Ryan answered all my questions even on his days off (Thanks again Ryan!).
These guys came highly recommended and didn’t disappoint, professional, fast, and very communicative throughout the process. Now I feel a lot safer knowing the structure is reinforced.
David was a lifesaver when it came to fixing our foundation issues. He thoroughly explained the problem areas and worked efficiently. We felt confident in the repairs and appreciated his attention to detail.
Nisan was very helpful on guiding me via the permit process for earthquake retrofit. Work was executed quickly. 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!
Our home needed retrofitting, and they did an amazing job reinforcing the foundation. They preserved the home’s character while making it structurally sound. If you need an expert who respects older homes, these are your guys.
We had a terrible experience with another contractor before finding these guys. They corrected the shoddy work, fixed our foundation properly, and treated us with respect. Finally, a business that stands by their word and does quality work.
We had a sinking foundation that caused doors to stick, but they fixed it with piers and proper leveling. Their team was professional, answered all our questions, and even followed up afterward. No more sticking doorsjust a solid, stable home.
A quick inspection by the crew revealed minor cracks that could’ve turned into big problems. They fixed them affordably and even gave tips to prevent future issues. So glad we called them before things got worse proactive and professional!
The neighborhoods of Oakland, from the Craftsman structures in Rockridge near the iconic Lake Merritt to the contemporary constructions in the hills overlooking the Bay, and the historic Jack London Square waterfront, are located on some of the most diverse landscapes in the Bay Area. The presence of slopes on the hills, fill soil and heavy soil of clay nature causes movement of the foundation to be a frequent problem. Long dry summers with rainy winters make the soil to stretch and shrink resulting in cracks, sloping floors or window and door gaps.
Our Push Pier Foundation Repair Systems services will be applicable to the complicated soil conditions of Oakland. We are able to restore balance, lift settled areas and block future movement using the help of precision-engineered push pier systems. No matter what is the location of your property it can be Lake Merritt, Montclair or Temescal, we offer long-term stability and tranquility – guarding your home foundations to the roof.
Beyond every successful repair there is a homeowner who eventually discovered his or her way to peace after years of stress and uncertainty.
The Home on the Hillside Close to the Montclair
A family realized that their back deck was inclining and floors were sinking. Our crew used 10 steel push piers to fix the base in the solid ground. The house was hoisted up to the point of rest, since then not a single movement.
The Craftsman in Temescal
This is a home that was built in the 1920s, the cracks could be seen and the corner was sinking. We have installed push piers in strategic positions below the points of concern to ensure that the structural balance was restored and so no further cracking would occur without the need to change the historic appearance of the home.
The Contemporary Construction by the Lake Merritt.
There was a more recent property which underwent addition and restructuring between the property and the old house. Both parts of the building were brought together by push piers to form a smooth and flat base that enhanced stability and resale value.
When foundation problems are overlooked, cosmetic harm is not the only thing that will arise. There is expansion of cracks, misaligned doors and windows and eventually intrusion of water or separation of framing may take place. A little repair may develop into a significant structural maintenance.
The early identification of foundation issues will save money and prevent the secondary damage to the homeowner. The push pier stops the settlement in the spot therefore not only protecting the structure of your home but its future value and safety.
One of the largest contributors of foundation settlement in Oakland is expansive clay soils. The soils swell in presence of moisture and contract in absence causing unequal pressure to the construction overhead. It is addressed by the use of push pier systems which anchor deep below the active layer of soil.
The piers are operated hydraulically into dense load-bearing strata which does not move with changes in moisture. The weight of the house once installed is transferred to this stable layer, thus avoiding the problem soil. The outcome is a foundation that remains flat, even with the extreme weather cycles – a very important feature to homes constructed on the fluctuating terrain in Oakland.
We’re here to help! Swiftly addressing these concerns is key. Our experts will promptly inspect and repair your foundation, ensuring the lasting strength and safety of your home. Reach out without hesitation for reliable assistance.
