"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they â completed the job, I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they are saying that leveling the kitchen was not included in the original scope, blaming the remaining dip on my kitchen island and fridge being â too heavy and lacking proper support an issue they failed to identify in the initial assessment. To properly address this problem, they are now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I cant help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that was not there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as standard and providing terms within the contract absolving them despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to â settle naturally a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you are considering foundation work, I strongly recommend looking elsewhere this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

Earthquake retrofitting services FAQs

Most earthquake retrofitting jobs take one week to 10 business days to complete. However, your professional retrofitting expert will be able to give you a more accurate timeline for your home once you complete an initial consultation. The total time may be longer for projects requiring more extensive work or homes with structural damage due to a prior earthquake.

You can expect to pay between $3,370 and $8,610 in earthquake retrofit costs, ranging from $500 to $15,000 or more, depending on your type of home and foundation and retrofitting method. 

If you have a slab foundation, you can expect to pay on the lower end, between $500 and $3,000. If you have a wooden foundation, that cost jumps to $5,000 to $10,000. A hillside home, not as vulnerable to earthquake damage, typically costs between $5,000 to $10,000 to retrofit while a soft-story home ranges from $10,000 to $80,000.

It is not advisable to try to retrofit your home without the expertise of a professional. These projects usually require a consultation with a structural engineer and a plumber for any gas-related adjustments. Working with a professional earthquake retrofitting contractor is the best way to ensure that any structural work done to your home will help protect you and your family.

First, you can expect the project to be loud. If you have pets, you might want to take them to a friend's house during the day so they are not disturbed by any of the loud noises. In addition, you’ll need to provide the retrofit team access to areas of the house that will need to be worked on, meaning you’ll need to relocate personal items, clear clutter, and make pathways for the crew. Once the project is complete, a local building inspector will conduct a final inspection to ensure that the retrofitting is up to code.

Earthquake retrofitting can increase your home value, making it a great return on investment. This feature is especially valuable in areas prone to earthquakes. Besides the increased safety value (not only for your family but for the next family who moves in), earthquake retrofitting also helps lower homeowners insurance rates. In addition, having your home earthquake retrofitted can make it easier to get a home loan since they are considered lower risk.
