"They assessed project, did preliminary design, got helical pile subcontractor. We paid for soil and test drilling, and for topological survey as requested. The sub contractor hired to do scaffolding never did it, so we had to arrange that. So after 4 months of all the prep and 3 or 4 site visits by the engineer, we were ready to go. They never produced the design. After 2 months of emailing and calling we never got a single response. So we were out a couple grand engineering fee, and lost the entire build season. Had to start all over. (This was for a collapsing Livingroom on piers, so it was kind of urgent.) Trying to decide if it is worth going to small claims court to recover our feet. But the big problem is it just did not get done and the engineer just ghosted us, very unprofessional."

"The landscaping of my home needed to be redone. I interviewed a number of Landscapers but after I spoke with Don of D&S Landscaping, Inc., I didn’t contact anyone else. Don told me which shrubs to keep and which to remove. He did a quick sketch of plants he would recommend that would do well in my yard. He showed me pictures of the plants and gave me a very fair written estimate of the cost. He asked for a reasonable deposit and we scheduled a date for the work to be done. He started when he said he would and finished on the same day. His crew is wonderful, polite and very hardworking. They worked from the time they arrived in the morning until early evening adding the unexpected bonus of mowing the back and front yard. Don checked to see that everything was done correctly and to see if I was satisfied. The front looks wonderful and I am more than just satisfied. I would recommend D&S to anyone looking for someone to do landscaping. You won’t be sorry it you do!"

FAQs for engineer structural projects in Warren, NJ

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.
