"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"Bob Warren was simply terrific, i had a great experience consulting on my crawl space. Really, Ive never had a crawl space and while having one in my first home i did not know what to look for that was in need of repair. Bob did a thorough job looking over it for me and very honestly delivered me feedback. Turns out i am not in a dire need of repairs but when i do, i know who to turn to. Thank you Bob, and GroundWorks for the professionalism "

"Would not recommend these people for foundation repair. My appointments were rescheduled 2 times with little to no communication. Took time off of work to be home for the installation and canceled on me that morning. Work quality was ok but definitely too expensive."

"I had Built Strong level my home and quite impressed. Their crews are extremely knowledgeable and experts at what they do. They took photos throughout the project, even custom fit/ repaired my foundation in specific difficult areas and my home now leveled like new. Impressed with Built Strong."

"It went very well!  They were really professional and I had them also repair some weak spots.  They were also very accommodating to the tenants."

"I am selling my house and needed to fix the foundation as it was sagging in one of my rooms.  I contacted E.J. and he came to the house and explained the entire process.  He was very friendly, knowledgeable and professional and answered all of my questions and concerns.  I received the quote when they said I would and found the price to be reasonable.  They did not try to up sell me which I appreciated.  The crew was also professional and clean.  They cleaned up around the house daily, I had no problems.  The floor feels solid now and no longer squeaks!  I am very happy with the work performed and the experience with E.J. and his crew was very smooth and stress free.  I will definitely recommend them to anyone who needs foundation work. <br />"

"I've dealt with a number of contractors throughout the years and I must say Adam Othman is truly one of a kind. Adam only works on one job at a time and the quality of service really shows. I knew Adam was the right person for our project immediately after our very first phone call. He took his time to really understand my objectives. You immediately get the sense that Adam is unlike other contractors. He is extremely sensitive to the client's budget and goes beyond the call of duty to get the job done right and on budget. Our project involved a 1922 Spanish home with a very low tiled ceiling. The ceiling was extremely out of scale in relation to the size of the room and it was our objective to raise it as high as possible. Prior to our contract, Adam dedicated so much time surveying the attic on two separate occasions and helped us come up with a solution that didn't require any major structural modification to our existing roof. Adam is a very methodical thinker. You could literally see his mind coming up with solutions as he quietly studied the project. You know you are in good hands because of the questions he asks. He anticipates problems before they even happen and that really put us at ease. Our project time frame was 4 weeks. Adam started the project on time and finished EXACTLY on the week he promised. He is by far the most organized contractor I've ever dealt with. Workmanship was superb. The work area was always left clean and the framing he personally did on the ceiling was truly a work of art. Before the drywall went up, he and I joked that the framing was too beautiful to cover up. He did absolutely beautiful work. The drywall crew did an outstanding job skim coating the plaster walls and their workmanship was as superb as Adam's. He clearly hires the best sub contractors in the business. It was the most stress free experience we've had from any previous contractor and that is testament to the way Adam runs his business. The living room is now quickly becoming my favorite room in the house and I am grateful to Adam for putting all his heart into it. He is truly a wonderful contractor who I now consider a friend. I have absolutely no hesitation recommending him to anyone. He is truly the best!"

"Will and his team at CXC did a great job replacing a failing stem wall perimeter foundation on my 1920s mid-city home. I bid the project out to six different contractors. His bid came in close to most and it became quickly apparent that his crew would delivery the highest quality and integrity to the job. His ability to accommodate my scheduling needs, the crew's many years of experience and overall professionalism, and the quick communication from the office administration all resulted in a great experience. A big shout out to WILL (Owner), CELSO (Foreman), and ROSANNA (Administration). Word of advice, get multiple bids and always verify general commercial liability insurance and that it covers the type of work that is going to be done. CXC's was easily verified...others were not and in some instance foundation repair was not even underwritten into their policies. CXC is BBB accredited, many others are not. I would not hesitate to work with Will and CXC again on my future projects."
