"I would not recommend this company. They performed fire escape inspections at two of our commercial properties and charged an outrageous amount for each. To make matters worse, they failed to communicate their payment terms upfront and then demanded full payment immediately upon receipt of the invoices?totaling thousands of dollars. Their communication throughout the process was unprofessional and unnecessarily rude. There are plenty of other companies that offer the same services with better transparency and professionalism. Look elsewhere."

"The salesperson David was very honest and had no interest in upselling. He strongly advised against any interior drains for my basement, and he instead recommended an exterior drain called HydroBlox for my backyard. The estimate for the HydroBlox was $3,400. The installation occurred a few weeks later. Three employees used a machine to dig a trench in my backyard, and then because of utility lines, they hand-dug another trench in my side yard. They installed the pieces of HydroBlox and covered them with dirt. I expect the HydroBlox to properly drain the water from my yard, but if they do not, then I will update my review in the future."

Providing Professional Engineering and Structural Inspection services to the Pittsburgh area. Proprietor is a PA registered Professional Engineer with over 15 years of experience.
"Tim is the consummate professional. He's very thorough in his inspection, and he writes clear reports with excellent pictures. His report on the termite damage was much better than that done by our original inspector. He explained everything he found so I felt like I had a good picture of what needed to be done. When he returned, my contractor was so impressed with him that he took his contact information to refer him to future customers who needed engineering reports."

Faust Enterprises Inc
General contractor. Owner operated. No employees. Cost is determined by job. No travel charges. Award Winning.
"Clint remodeled my upstairs and downstairs bathrooms in 2019. I originally thought he had done a great job, but my naivety got the best of me. I brushed off things like paint splatters and runs (though he made multiple comments on the pride he took on his paint work), and tile not set flush or with even/consistent grout gaps (he blamed it on my old house w no right angles/flat walls or floors), but I didn't have a great frame of reference back then. Clint went MIA mid way through the project, ghosting me only responding after I reached out to the design consultants that subcontracted him. He said he had ran into health/family complications, along with other prior scheduled projects, but his lack of communication left me to wonder. He eventually returned but technically never completed my bathrooms, as he never finished the upstairs threshold. Worst thing was his choice of metal flashing for the shower pan. I just had to demo the entire shower due to corrosion and leaks to downstairs. "

Arnold Construction
3 Employees. Uses subs for larger jobs.
"Like any contractor they talk about how great of a job they do. In this case the kid has the knowledge to do a good job but like most fails on execution. He just can't do it. Ratter than bore you with the detail of how I got screwed by Arnold Construction I would just warn anyone that thinks about using him to not pay for the job until it has been completed and inspected. He also failed to contact zoning once the structure was completed to have an inspection. If you don't have an inspection you can't get other permits, like electrical, until the inspection is complete. There are to many other good contractors out their to waste your time with someone you can't trust. You've been warned."
