Pittsburgh Structural Engineer Reviews

Pittsburgh Design and Engineering Services is hands-down THE company you need to use for any and all structural engineering needs. I placed a house under contract that had foundation issues and was both nervous and concerned about what the repairs might entail. Firas, the owner, responded to my inquiry within an hour and was very accommodating in scheduling the onsite visit. His knowledge, professionalism, and attention to detail seriously cannot be beaten. He correctly identified and quantified the issues at hand--something two other contractors I had brought out failed to do. I am so happy I spent the extra money to have him come out, as it has made me much more comfortable in my upcoming purchase and I am now using his observations as points of leverage in my negotiations with the seller. I would highly recommend Pittsburgh Design and Engineering Services to anyone and everyone who is involved with real estate (both commercial and residential) and in need of the expertise of a structural engineer. Firas is one of the most down-to-earth, honest, and knowledgeable professionals I have come across in the greater Pittsburgh area and I look forward to doing business with this firm for years to come.

I had Firas come over to my home to inspect a crack in one of my joists. He analyzed and provided me with clear advice on how to proceed in repairing the issue. He also performed an inspection of my foundation and outside areas for other issues. He noticed things which didn't catch my attention.
As a new owner, I want to ensure I'm doing everything I can to prevent major issues from occurring. Pittsburgh Design & Engineering are looking out for your best interests. I'll be adding them to my book of trusted professionals. Thanks again!

We are first-time homeowners looking to check if a wall was load-bearing for a potential removal. I called several structural engineering firms and Firas was the only one to pick up when I called (the others never returned my calls). He was courteous and was able to schedule with us quickly. When he came to our house he was thorough and explained his process in great detail. We really felt like we could trust him and he did not try to push us or upsell us on anything. Highly recommend!

I was lucky enough to find Firas who was able to get me scheduled within a tight timeline. He provided me with a detailed and clear report that outlined the specs and calculations needed for the placement of a structural lvl beam due to the removal of a load bearing wall during my kitchen remodel. He was extremely helpful and thorough throughout the process. I just want to thank you again, as our contractor followed your all of your guidance and the install went smoothly and our inspection went along without any problems. Thanks again!!

Firas was a lifesaver for me when a misinformed home inspector erroneously flagged floor joists as incorrectly installed in a 2 year old Ryan Home. My seller employed Firas to evaluate the situation. Not only was he accommodating with his schedule, he was super helpful in explaining why the inspector was wrong and he was able to relieve any fears from the buyers of the home. I would highly recommend him to anyone needing engineering services.
