"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."

For more information or to schedule your inspection, call today!
"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."

We offer free inspections to homeowners looking to sell or potential homebuyers. We also are opening our new office in Riverside. Call today!
"We hired Professional Foundation Repairs (Ozzy and Darin) during our home purchase after they identified foundation/leveling issues. After the work was completed the leveling showed little improvement and they told us the contract ?wasn?t specific enough.? Four years later three different foundation companies inspected the house and found multiple areas where the previous repairs are failing and large visible sections (including the entire front of the house) were never brought up to code or properly retrofitted. I contacted Ozzy and was initially told Darin would cover the corrective work (there are text messages confirming this), but the company then stopped returning calls and messages. Darin (the owner) has not returned my calls. I have inspection reports, photos of the deteriorated repairs, and our text messages documenting their agreement. Their advertised 10-year warranty proved meaningless in practice. Bottom line: poor workmanship, broken promises, and no aftercare. I canno"
