"Finding someone trustworthy that does a great job with great customer service is hard to do. When the project is expensive it makes it more nerve wracking to decide who to go with. If you are lucky enough to find someone that checks those boxes, they become your go to people for your projects and as well as who you recommend. A few years ago I had Hoffman replace my driveway and was completely happy with their service from initial contact to completion. Years later I’m still completely satisfied with my decision to use them. Recently I decided to pour a shed pad and replace an old back patio. There wasn’t a doubt in my mind on who I should call. Like last time the entire experience was top notch. Jessica is amazing to work with from the start and is very friendly and communicative. The owner Mark really cares about the quality of work and clearly appreciates your business. His son, who runs the concrete crew, is also awesome to work with and really cares about a customer-first approach and performing quality jobs. The rest of the crew is also very engaging and respectful and performs high quality work. If you or someone you know is looking for concrete work I cannot recommend them enough. I have a high expectation for work done at my house and they exceed those expectations. You cannot go wrong giving them a call and having them perform the work. They will continue to be my go-to company for all things related to concrete."

FAQs for major home repair (general contractor) projects in O Fallon, IL

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.
