There were issues with a piece of equipment he rented-not his fault, that prolonged the project by many weeks. At the end, he gave us a new quote of 30,000. He stated this was for hours worked and many more days than originally needed. Unfortunately we didn't pay attention to days he was there, hours nor crew. There were days he didn't come, his crew would be there for an hour or so and we didn't keep track. Not once did he mention how much more it would be. He made a statement that he'd have to rent the equipment longer and that would increase the price, but that was all. We used our entire savings, and had to pull out 10,000 from our 401K to pay him. We now have a dirt lot we can't do anything with due to no funds. The work itself isn't bad. The job was well done. But I'd keep track of exact hours, crews and make everything written down in the contract. This destroyed us financially.

I needed a full pool removal and, after getting several quotes from different contractors,…read moreultimately chose Colossal Excavation. It turned out to be the right decision. From our first meeting, Francisco took the time to clearly explain every step of the process, including obtaining the city permit, demolition, backfilling, soil compaction, and providing a soil compaction/inspection report that will be valuable if I ever decide to build an ADU. He also walked me through the removal of the pool equipment, demolition of the surrounding flatwork, and the proper capping of the electrical and gas lines. His knowledge and attention to detail gave me confidence that the project would be done correctly. On top of that, his pricing was competitive and very reasonable. Francisco and his father, Rigo, make an outstanding team. They arrived promptly at 7:00 a.m. every day, kept me informed throughout the entire project, and coordinated every step seamlessly--from city inspections to imported fill dirt and soil compaction testing. Everything happened exactly as Francisco had explained from the beginning. Throughout the demolition and backfilling process, they worked carefully and professionally, always prioritizing safety and leaving the job site clean and organized at the end of each day. It's rare to find contractors who are this dependable, communicative, and take such pride in their work. I highly recommend Francisco, Rigo, and Colossal Excavation to anyone needing a pool removal, excavation, grading, or site preparation project. Their professionalism, honesty, and quality of work exceeded my expectations, and I wouldn't hesitate to hire them again.
