Dave is easy to work with and no problem big or small is unsolvable for him. I reccommend DRH for their knowledge, experience, and punctuality.

Worked with Dave, great guy. I felt he was really set on helping me out rather than just generating work. I needed him for a crawlspace inspection as a result of a home inspection when we sold our house. I knew the crawlspace was fine, but got extremely nervous when they required us to have an inspection by a structural engineer. At one point they were asking us to do 16k worth of work...to a crawlspace. After the inspection, Dave's more realistic recommendations cost us only 2.5k. Obviously, definitely worth the money.

I've worked with DRH Engineers on a regular basis for the past year. They've done a substantial amount of work for us during this time. DRH has always offered great service to our firm. DRH's pricing is fair, their work is precise, and the turn around time to produce certified plans for our solar company is great as well.

I reached out to several structural engineers familiar with retaining wall details for Fairfax county codes. David Hall responded quickly and due to my tight time requirements, visited my property 2 days later on a Saturday. I had the final Retaining Wall Plans in my hand Wednesday and breezed through the permit process on Thursday! David's final structural drawings saved the day!
