After several years of learning the trade, he opened his own company and named it after himself “Lainez Contractors”. Oscar and his team are focused more on quality and honesty than anything else. He always had a plan of quality work to be done can provide quality works at honest and reasonable prices.

My real estate business is based in Brooklyn, NY; my partner and I are investing in Chicago via a 3 family in the Old Town section. Around the middle of October ’18, the foundation started to leak water and our tenant’s apartment was unlivable. Contractors, it seems in Chi-town, are very hard to find. Oscar was the first one to call me back and meet me at the address. We both inspected and went over what was wrong and what had to be fixed. Oscar even caught a few (very legitimate) hidden problems, such as holes and gaps in the brick mortar and seams between the wall and ground. Cutting to the chase: everything was fixed in a very professional and timely manner. Oscar communicated with me a lot and is very patient when it comes to going over the details. I wish he was in New York.

As a long- time homeowner who also has had parcels of income properties thru the years, I regularly require the services of general contractors. I usually came across 3 categories: 1. Mediocre. 2. Good. and 3. Excellent. Thanks, Oscar, Romero and the rest of the O&L crew. They were easily in the highest rung. Without me even asking, they suggested innovative ideas that other contractors I have in the “Excellent ” rankings said was too hard a job, totally re-routing electrical, water and gas pipes, giving me much more space, and the quality was top notch. Ask him to show you the before- after pictures from our basement. You’ll be as impressed as I am.
