"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

"Don?t be fooled by Chapter?s sleek branding or ?hassle-free? pitch. Our semi-gut reno of a 3-bed, 2.5-bath Brooklyn co-op has dragged on for a year, burning money, time, and sanity. Chapter claimed high-end services, but this was not the reality. There was minimal project management, workmanship was terrible (damaged new items, blamed ?site conditions? when they couldn?t do basic work they?d promised, had to re-do many items because quality was so poor). They missed every deadline and overshot the timeline by months. We were often forced to procure items ourselves because Chapter weren?t engaged or competent enough to do so (they even failed to purchase a one-of-a-kind marble slab we designed our bathroom around. It was sold to someone else and we were forced to redesign last minute). They gaslighted us whenever we raised concerns and pressured us to make payments when work was defective / incomplete. Beware the other glowing reviews you read. "

FAQs for major home repair (general contractor) projects in Whippany, 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.
