My husband and I are very happy with the French drain that Foundation Builders installed. Their quote was fair, they worked efficiently, and left the work area clean and tidy. If you end up with Andreas as your foreman, you'll be in good hands. After the rains in February, our house is nice and dry thanks to Foundation Builders.

Foundation Builders did a great job for us. We had water intrusion issues related to bad drainage systems in a somewhat tricky backyard configuration that ended up requiring helical piers for our fiundation. The entire Foundation Builders team worked with us every step of the way, showing a willingness to make adjustments on the fly.

I had a crack in my slab foundation that was leading to several problems. Although it wasn't a serious structural issue, it was very discouraging to remodel a bathroom and then have cracked tiles a year later, or to watch large cracks in my walls and ceiling grow over the years.

Minor but numerous cracks had appeared on the interior drywall over the past few years and there was no drainage away from the foundation. My initial request was for an inspection of the crawlspace foundation and foundation waterproofing.

so I called foundation specialists to check my foundation amd floors sinking and out of the 5 only 2 called back and set appointments for their assessments. Only 1 showed up and provided an estimate 10 days later for a very high price with no explanation on the work they will be doing.

Needed an earthquake retrofit for my home. I have a raised foundation and my insurance is with CEA. As CEA has threatened me with a letter saying my insurance may be cancelled without a retrofit I decided to find a contractor and have it done. I found Foundation Builders. They gave me a competitive contract for the work.

Foundation Builders were very responsive, and they reached out right away to respond to my request. They took the time to assess my mold concern to give me a rundown of what the next steps would be. I appreciate the team going over and beyond to give me the best solutions.

Foundation Builders came out to inspect my home after I noticed moisture in my garage. Their team was very professional and took the time to show me the root cause of the problem. They explained that a new drainage system would solve the issue and gave me a few different options to consider. I really appreciated how clearly they explained everything.

Structural & Retrofitting Services For Homes & Commercial Properties

At Foundation Builders, we can execute structural and retrofitting work on a vast range of properties. Here are the details for readers in brief.

Residential Homes

Your needs could vary from fixing minor foundation cracks to complete structural leveling for your home, and our team will do everything to restore the property to its pre-damage stage.

Office Buildings

Are your building’s safety and compliance being sidelined due to weak ground-floor structures? It impacts your property’s value and safety. We will quickly reinforce the space for you to ensure it meets all modern safety standards.

Factory & Industrial

We are ready to execute any seismic retrofitting or foundation repair service you may need for your factory; ensuring your structure is fully prepared to withstand earthquake activity.

Steps to Follow After Structural Damage

When your home or building is affected by structural issues or seismic shifts, you need to be careful and follow a few simple steps to ensure the complete safety of your property as well as your loved ones.

Identify the Signs of Damage

If the cause of the structural issue cannot be immediately detected, you should look for visible signs like wall cracks, uneven floors, or sticking doors. Try to look closely at foundation walls and ceilings for new gaps. Check your crawl space for moisture or shifting. If you can’t assess the extent of the damage on your own, give our team a call immediately for a professional inspection.

Contact Your Insurance & Engineering Experts

Once you identify a potential structural failure or seismic vulnerability, it’s crucial to document the issues as early as you can. Take high-quality photos or detailed notes of all cracks and shifts. You need to keep a record of these for insurance claims or structural engineering reports. Make sure you have answers to potential questions regarding when the cracks first appeared or if the building has undergone previous retrofitting.

Ensure Occupant Safety

If you must enter a building with significant structural damage, you need to do so with extreme caution. Structural instability can lead to sudden collapses. Avoid areas with large ceiling cracks or leaning walls. If the damage is severe, turn off the main gas and electricity lines to prevent secondary hazards like fires or leaks. Always prioritize your safety before attempting any minor DIY fixes.

Begin Reinforcement Immediately with Professionals

In structural situations, you need to act quickly. The longer you wait to address foundation settling or soft-story weakness, the further the damage could spread, leading to higher repair costs. Once our professionals declare the best course of action—whether it’s leveling or retrofitting—you should begin the repair process to secure your investment.
