"Two large projects. Couldn’t be happier. On time, excellent workmanship, wanting to please but open to making suggestions when asked. Superior design and quality of work. Reasonably priced. Thorough clean up after the job . Owner on site to supervise work. Owner very knowledgeable. Owner returns calls promptly. Neighbors LOVE our fencing and landscape."

"Edgar and his employees were amazing. Their bid was the best. Other guys said they would have to rip up pavement that this crew could do no problem minimally. The guys were so well groomed and polite. Not that that matters but it was an extra bonus. Lovely crew and incredible job in a few days. I will for sure use them again."

"Giovani and Dell of Ultra Construction were great to work with and they responded quickly and efficiently to our contractor inquiry. They came out the next day and provided a fair and reasonable estimate. Dell and his crew, including Julian came out and had the concrete walkway and stairs installed in just one day. It looks great and we couldn’t be happier with the results. Their prep work and cleanup were outstanding. Would highly recommend this company for any concrete construction work"

"This was basically a demolition project. I had to have a 75 year old concrete circular retaining wall buried in the center of my asphalt driveway that had to be removed so that we could plant an oak tree. The wall was approximately 25 feet in circumference, 4 feet high and the concrete at least 3 inches thick. The bottom foot and half of the wall was covered with earth that had to be dug out by hand. Jose accomplished this extremely difficult job in a day and a half working right along side his helpers. He was able break up and haul away the concrete and did a great job cleaning up the site. He is courteous, professional and his rates are extremely fair. I would definitely recommend him for any job."
