"Mr. Ohi came to our home to inspect the foundation and support walls prior to us doing home renovation work. He did a thorough visual inspection and level measurements and located some small issues, but, thankfully, recommended that no foundation work be done. Mr. Ohi was pleasant to be with and knowledgeable about residential support structures."

"Bashir and Noorullah were a pleasure to work with. They were very detailed, providing a full set of plans to have a load-bearing wall removed in my home. Bashir was attentive and he and Noorullah answered all my questions. I would have no problem providing a strong recommendation for Structurist for any structural engineering needs especially when it comes to your home."

"I had a list of concerns and Mr. Gutt explained what he thought about each and gave recommendations so that I understood clearly. He was willing to answer as many questions as I had and stay until I had no more. Concerns: large tree 2 ft from house, recent plumbing work by plumber enlarged a hole in joist, check on bathroom subfloor repair and wobbly floor in a bedroom. Very clear instructions on how to fix the joist and subfloor. The tree wasn't a structural danger but advised to have it removed anyway."

David was on time and very professional. He spent an appropriate amount of time evaluating the 2 areas we had requested. He documented the inspection w/ photos, measurements, and sketches. He provided a verbal preliminary report and is to provide a written final report w/ specifications for the mods we are proposing. (Removing a wall upstairs and a post downstairs.) We were happy to hear that our mods were going to be less complicated than originally thought and consequently less expensive. We have the peace of mind that the proposed changes are structurally sound and will be done correctly.

"Working around the house initially made us nervous but it was clear then and throughout the project that Suncrest?s engineers are incredibly skilled and excellent builders. Work started in June and finished in September. We were sad to see them go! Bryan, the foreman, was fantastic throughout, and communicating regularly and making sure that our lives were minimally disrupted. He answered every question we had ? even going out of their way to research energy issues not relevant to the work they were doing. 
Although there was an expected hiccup of a re-design based on what they found after starting, Suncrest tackled those as timely as possible. They responded to every request or question with a can-do attitude.  In fact because of the extra time spent waiting for plans to be re-done and re-assigning crews to finish the job, they elected not to charge us some of the overrun charges that come with a job of this scale. 
The stairs far exceeded our expectations; we were completely blown away. To say they installed new stairs is like saying Michelangelo painted a church ceiling. Every detail was addressed with top-of-the-line materials. When we explained we were concerned about paint fumes, they didn?t hesitate to specially order water-based stain. They matched our existing stairs as much as possible (handrails, paint color, floor molding, even bar railing) and covered their work throughout the house so that it actually looked better than before. 
All in all, I would highly recommend working with Suncrest.  They are professional, ethical, friendly and will work with you to find the right design. They do it all, from electric, to woodwork, to plumbing.  We would not hesitate to use them again.

"James and his team were quick, punctual, and James was incredibly responsive, always responding to calls or texts within minutes. Proposed a sound engineering solution to a challenging problem, where other contractors I spoke to offered expensive decorative solutions that would not have addressed the problem. The finished work is also beautiful, and adds to the appeal of our back yard. I would hire him and his team again."

FAQs for engineer structural projects in Arlington, VA

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.
