He got ahead of any issues and resolved potential problems that could arise. He knew exactly what the city would require and did what needed to be done which saved us an untold amount of time and money. I did not know him from Adam, he works at a very different level of ability and knowledge. His pricing for me was the best! He is a gem, get him if you can!"

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

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.
