"Gabriel and Lana and their team have been incredible to work with for many of our projects. They are responsive, professional, accommodating to our busy schedules, and more importantly to the often sensitive schedules of clients and owners. Their inspections are thorough and we have great trust in their ability to deliver a quality assessment. For anyone inquiring, GLS would come with our highest recommendation."

"GLS was very professional and prompt with their communication and delivered quality work. We interviewed a few guys for the job, but only trusted Gaby as he was straight forward, very knowledgeable and fair with his pricing. Hands down the best experience related to my construction project thus far. Highly recommend!!!"

"I am NJ, and NYC licensed Professional Engineer. For many years GLS performs asbestos inspections/investigations on my projects. If you run a checklist of essential items, they all will deserve the highest mark. Timely and polite service - check. Knowledge of the latest regulations in the convoluted and highly regulated field - check. Minimal required number of relatively expensive laboratory tests - check. The GLS team does not miss asbestos - check. Recommendations on asbestos abatement - check. Highest mark - check."

"Gabriel was personable and helpful. With my wife expecting, I needed someone that would do more than just test the air - I needed to see someone who knows what they are doing and cares. Gabriel did all the relevant testing but also spent an extra hour with me reviewing how to keep my home free from hazards."

"Straightforward, timely and professional service from the inspectors at GLS, no run around, no gimmicks! Once you have your plans in place, they’ll coordinate and execute the inspection process seamlessly. They were recommended to us and we’ll happily continue that cycle of recommending them to others!"
