"I did like James. I hired him to draw up plans for building and safety for existing exterior entry stairs. I took all the measurements for him and sent pictures to help him. He drew up the plans in a timely manor, he was paid in full. Building and safety wanted revisions. He did the first revisions but building and safety asked for more revisions of information that should of been included in the original plans. He said he would work on them and get the revisions to me. After months of waiting I sent numerous texts, calls and emails he never responded to any of them and he never did the revisions. Very very disappointed that I have to hire a new engineer to finish the job I paid him to do."

FAQs for engineer structural projects in Running Springs, 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.
