"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."

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"
