"Tom at TAS Engineering was professional, friendly, helpful, patient and highly competent and efficient. He did the assessment of my attic structural issue and identified the simplest and most cost-effective solution. He ensured that my contractor did the work to his specifications and provided the certified engineering letter that all had been addressed properly. This was exactly what I needed. I would highly recommend him and would hire him again."

"Darren was professional and courteous. He called to let us know he was running a bit late. He was great at explaining things and very thorough. He got an official report to us in a timely manner. But most importantly he assured us the house we were about to purchase was structurally sound. He even suggested ways to keep the small structural shifts in the older home from occuring."

"RES Engineering was awesome. I'm building a deck in my back yard and had done a ton of code research. I had the entire design planned out already and really just needed an engineer to tell me how deep I needed to make my footings. Through a simple phone call, RES consulted with me on how deep the footings should be as well as the live/snow load and soil assumptions that went into it. They didn't even charge me for their advice. I'd recommend them to anyone who needs some engineering support."

"From the start I knew Ryan was the right person, because he called me, the only one of the engineers that actually called me. He communicated regularly, let me know straight up the results and explained it all to me. Is also willing to answer questions from my contractor."

FAQs for engineer structural projects in Boulder, CO

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.
