"             We called the company  (AAA Construction  Restoration Services) to repair a leak in our roof. John Walters responded immediately and made an appointment to come to our home the next day. He was on time , looked over the situation and gave us an estimate by text.!  We agreed and the very next morning , on time as promised, several men showed up and began working right away.  They were very hard working, no goofing around, and repaired the problem . They even painted an area where there was damage (which was not even in the estimate) They also cleaned up everything and hauled away any debris.
           Having previously dealt unhappily  with Miami construction companies, I was very happily surprised and pleased with all aspects of the way AAA dealt with me.  They were ON TIME,  EFFICIENT, REASONABLE and DID  A GREAT JOB.  I would recommend them  to anyone with a similar need

"Steve not only knows construction and design but can also think outside the box when issues arise. He has good ideas and can help the less experienced through a project. Not only that but my master sewer line backed up while he was working and he brought his snake out to try to unclog it which wasn’t included in the original scope of work. Overall he’s a very nice guy who gets the job done right."

FAQs for engineer structural projects in Jacksonville, FL

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.
