"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

"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

Generally, the retrofitting process can take two to four weeks. Your contractor will let you know if staying in your home for the entire project is feasible. However, most people are able to remain at home. If your home is undergoing earthquake rehab, it's more likely that you'll need to leave until work is complete. Your earthquake insurance may cover boarding costs if your home is deemed unsafe.

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.

Ensure proper ventilation, fix leaks, and schedule regular pest inspections to protect your property.

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.

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.
