"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 truly regret hiring HavenHub for my backyard project. After a salesman came to our door, he designed our landscaping plan — retaining wall, stairs, shed pad, boulders, and sprinklers — and quoted $24,995. I paid in full around July 8, 2025, with a contract promising completion by July 28. No one ever showed up until I contacted them. Since then, I’ve dealt with four project managers, endless delays, broken promises, and almost zero communication. One crew came but didn’t know what they were supposed to do and couldn’t reach anyone for direction. Another poured a footing wrong, according to one of their own workers. Months later, my yard is still torn apart, and HavenHub continues to ignore me despite taking full payment. I’ve had to involve a lawyer just to try to get a response. Terrible communication, unreliable crews, and no accountability. Be very careful before hiring this company."

"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."

FAQs for engineer structural projects in Claremont, CA

The right type of engineer depends on the house you’re looking to build. Most builders work with structural engineers to ensure safety of the structure itself. For builds beyond a typical home up to 3,000 square feet, you might need a construction engineer.

Engineers work in a variety of fields, specializing in anything from structural to electrical work. Some work independently and are hired by large construction companies for complex projects. Others form engineering firms that oversee the entire construction project. They spend time on construction sites, but also work in offices to make calculations and prepare recommendations.

All 50 states require licenses for building engineers. Don’t work with a professional who doesn’t have an active license or doesn’t want to share their licensing number with you. It’s a crucial step in making sure you’re working with a reputable expert.

When you build an extension, you most likely need a structural engineer. They’ll work with the builder to make sure the space is safe, but also make sure that your addition follows the right zoning laws.

Loft conversions generally call for an engineer. The project will include working with beams and trusses that most likely hold up your roof or other parts of your home. You need a pro who can calculate the impact of making any changes.

Structural engineering is technically a subset of civil engineering. Most commonly in residential projects, civil engineers are accountable for sewage, water, and drainage, while structural engineers focus on the structure and its integrity.

Structural and architectural engineering are very similar. Both work with architects to make sure the designs don’t just look good but will hold up. The former is typically involved early on, making initial calculations. The latter is more closely involved with the architect, carrying a design from initial concept to actual build.

Hiring a structural engineer costs between $300 and $650 for most homeowners. The price is typically fixed at the beginning of the engagement. Your budget may need to range upwards of $1,250 if the pro doesn’t just provide an initial evaluation but partners with you throughout the construction.
