"I contracted with TVP for engineering plans for a home addition in February, 2023. The sales person Phil McDodson, made an agreement to stay with the project through to the permit but walked away as soon as the county required additional information. At that point Janae Spinney stepped in and would not quit on me until that promise was complete. A special thanks to Joseph and Caleb for getting us through to the end.

"Israel and his team were great to work with and I am really happy with both of the projects they competed for me. They replaced an old, failing retaining wall with a beautiful stone retaining wall with a French drain behind it. I showed Israel pictures of what I wanted it to look like and his team did an amazing job making my vision a reality. They were careful with my existing plants and landscaping and went above and beyond by moving and repotting a shrub that I was unable to move by myself before the work began. They also replaced parts of my backyard that had been removed by neighbors and built a beautiful new fence and gate out of cedar. They did an amazing job matching the style of the existing fence and my yard looks so much better now. I am so happy with everything and I would work with GI Landscaping again anytime!"

FAQs for engineer structural projects in Portland, OR
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.
