"Bait and switch. I obtained multiple quotes for my foundation. Dalinghaus Construction quoted me 19 piers to stabilize my home. I questioned why their competitors were quoting me over 30 piers; and they reassured me I was being over quoted by their competitors. Long story short, I went with Dalinghaus. During construction, a rep (David F) came by to drop off some tools and found that 19 piers would not be enough. They said I needed 14 more piers (totaling 33– same as their competitors). I’m stuck because I cannot leave my home half stabilized. No other reputable company would complete the job if another company started it. I was obligated to move forward with Dalinghaus. No one called to apologize for the misstep. They invoiced me and could care less how much this would affect my family. They proceeded to install14 more piers but left 14 large holes— they said backfilling was not part of the scope of work, while the original 19 were backfilled. Insanely strange why they think I wanted 14 large holes at my home. So this is where they gave me a “discount.” They backfilled the holes for free. Free? It should be included in the work. All in all, why do I have to pay for a mistake of this magnitude? I’ve tried to work it out with them peacefully but they have not provided me anything that would make this right. Only excuses why they should not compensate me. They have no integrity. They only care about their reputation at this point (they want my bbb review taken down). I would like to be compensated for the 14 additional piers that were missed from the original quote. 14 additional piers is a completely new job, not a “new work order.” They are the professional and should have done a more thorough assessment to provide me an accurate quote. Their competitors seemed to have done so but I was sadly duped by Dalinghaus. They baited me in and switched the price after the work started. $38k is a lot to lose. I have 2 small children and a home that needs to be completed. Ps. I’ve been waiting over 2 months for a resolution."

Earthquake Retrofitting questions, answered by experts

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.

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.

Projects will vary based on size and scope, but an average earthquake retrofit takes between two weeks and two months. This includes the initial evaluation and plan, bidding and contract paperwork, permitting and approval process, actual work, and final inspection. Your contractor should give you a more accurate time estimate for your specific project, and they may be able to estimate how long the permitting process will take for your area.

Depending on where you live, your insurance company may require you to have a seismic shut-off valve. It depends on local regulations along with the specific provider. If it’s not a requirement, many providers will offer a discount if you install an earthquake valve, which can save you 5% or more. Contact your provider to learn about potential savings for your plan.

Hearing or feeling vibrations in your house can be unsettling, but there are a few possible causes for a vibrating noise in your wall or floor. Light bulbs and fixtures, circuit breakers, loose pipes, or faulty wiring could all cause vibrations. If you’re not sure what’s causing the vibrations, you can call a contractor to assess your home and narrow down the cause.
