"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"We asked Sam to meet us with very little notice, and he was able to accommodate our schedule. He came on time, inspected the property in question, and two days later we had a very thorough written report which documented his observations , recommendations and conclusions. He also provided a diagram of the suggested repair for the problem area. We were very happy with his services."

"Our home had an outdated layout. All the different living spaces were closed off by walls. We wanted an open concept from the living room to dining room to kitchen. After interviewing several contractors, we felt that Pacificland Constructors better understood our needs and their price fit our budget.
Martin and his crew at Pacificland Constructors came in and did an outstanding job! The
first thing that they did was place up plastic ?walls? to block off the dust to the rest of
the home. They also laid down two layers of thick cardboard paper on the ground too
prevent the existing floor from being damaged. After the prep work, they quickly
removed the two non-load bearing walls. Pacificland hired an engineer to do the
structural design of the load bearing beam that would be used to support the roof and ceiling in lieu of the existing wall. A temporary wood wall was constructed to support
the existing ceiling and roof while the crew removed the existing walls. Next they
installed the structural beams, wood posts, and the metal connectors. After the beams
were set in place, the temporary wall was removed.
Once the flush ceiling beams were installed, came all the easy finishing work. The crew
moved all the existing electrical outlets and switches to adjacent walls, installed the
drywall and did the rough taping, and closed up an existing window. Pacificland
Constructors was done in 5 days and did a great job cleaning up the job site. Whenever I
had a question all I had to do was either call, text, or email him. He was very accessibly
and helped answer all my questions during the construction process. I would definitely
recommend and use him again for future projects.

FAQs for engineer structural projects in Claremont, CA

You should replace floor joists as soon as you see clear signs of structural trouble—sagging floors, wide wall cracks, uneven door frames, wet or rotting wood, persistent squeaks, or windows that no longer latch. Tilted or sinking supports in the crawl space are another red flag. If you notice any of these signs, call a pro right away to keep your home’s structure safe.

If the joists are exposed from below, a pro can swap them out without touching the finished floor above. In an unfinished basement or crawl space, you’ll often see the joists and can easily reach them. When insulation, subflooring, or finished flooring blocks access, the crew must remove these materials before repairs can begin.

Sistering allows a pro to reinforce a cracked or undersized joist without tearing up the entire floor. The contractor slowly raises the frame, then fastens a new joist snugly against the damaged one to share the load. When done correctly, sistering restores full structural strength and keeps the floor level without the cost of a complete replacement.

Floor joists installed correctly in a stable environment can last for 100 years or more, often outlasting the house itself. However, termite damage, moisture, leaks, and other problems can significantly reduce a floor's lifespan. For instance, if the floor is exposed to consistent moisture, you'll likely need to replace the joists every 20 to 30 years.

Homeowners' insurance covers floor joist damage resulting from sudden and accidental events, such as fire, windstorm, or water damage from a burst pipe. It will not cover repairs resulting from gradual deterioration, poor maintenance, or termite infestations. Review your insurance policy and consult your provider to verify the conditions that guarantee full coverage. Doing so ensures you are fully aware of your responsibilities and can plan your repair work with complete confidence.

Floor joists are essential structural components that provide a stable foundation for your home. They directly transfer the weight of floors, furniture, and occupants to the foundation, ensuring stability and a safe living environment. Without these robust beams, the structure would face compromised load distribution, leading to potential safety hazards and costly repairs. Proper installation and maintenance are crucial for long-term durability and safety.
