"I searched many and started off with others and nobody came close in handling what we needed. I found Richard, he came in and took care of it all; it was completed in a timely manner with his accurate thinking. He definitely thought ahead and it saved me a lot of time, grief and money. He got ahead of any issues and resolved potential problems that could arise. He knew exactly what the city would require and did what needed to be done which saved us an untold amount of time and money. I did not know him from Adam, he works at a very different level of ability and knowledge. His pricing for me was the best! He is a gem, get him if you can!"

"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."

"Do not be fooled by the positive reviews. It’s evident they are paying for reviews or having their buddies create fake ones. We had a lackluster experience with Haven Hub. I’m giving them two stars bc the job eventually got done, but I wouldn’t recommend them. Poor communication, project manager changes with no notice, and unprofessionalism made the process frustrating. (I have an endless list of things that went wrong but only 1000 words.) Contractors tried to upsell us under the table for work already in our contract, and the concrete wasn’t poured to spec. Crews didn’t show up for weeks; they left a dirt pile that got us warning from the city. Sprinklers in the park strip were initially promised by the salesman, then left out of his poor drawing. Even when we scheduled a final wrap-up date, they didn’t show. The park strip was never finished, despite many promises to do so. We signed March 5 and didn’t finish until May 29 — nearly three months when it should’ve taken weeks"

FAQs for engineer structural projects in Northridge, CA
The timeline for basement ceiling modifications spans four to 12 weeks, with the specific duration depending on your chosen method and project complexity. Floor-lowering projects often require more time due to careful excavation and foundation reinforcement processes.
Weather conditions, permit processing, and unexpected structural discoveries can extend the projected timeline. Most homeowners should prepare for some disruption to normal household activities during critical construction phases.
Converting previously unusable basement space into a functional living area often increases your home's assessed value, which may impact property tax obligations. Tax assessment practices vary significantly between municipalities, with some jurisdictions basing calculations on finished square footage.
To avoid surprises, contact your local tax assessment office before beginning construction to understand potential tax implications and budget accordingly for any anticipated increases.
Engaging a qualified structural engineer represents an essential first step for any basement ceiling project. These professionals evaluate foundation integrity, soil conditions, and load-bearing requirements to determine feasibility and recommend appropriate approaches.
Their expertise helps prevent potentially catastrophic structural issues while ensuring compliance with building codes. Although this consultation adds to initial expenses, it provides crucial guidance that may prevent costly mistakes or safety hazards.
Historic or aging properties present unique challenges when modifying basement ceiling heights. Older construction methods, outdated materials, and accumulated settlement issues require specialized assessment. Heritage designations may impose additional restrictions or requirements on modification approaches.
House-raising often provides advantages for older homes with compromised foundations, as it allows simultaneous foundation repair or replacement during the ceiling height modification process.
While professional contractors must handle all structural modifications, homeowners with appropriate skills may complete certain finishing aspects independently. Tasks potentially suitable for DIY include non-structural elements like painting, trim installation, or basic finishing work.
However, all excavation, foundation modification, and house-lifting operations require specialized equipment and expertise. Attempting structural work without proper qualifications creates significant safety risks and potential property damage.
