I was very fortunate to have them realize a project that was centered around creating an in-law apartment in an existing space in my home for my father. They worked with me every step of the way which resulted in a collaborative design with a nautical theme. The end result is stunning and everyone who sees it wants to live in it! Thank you Timber and Megan for making my vision a reality."

"Vincent Police, the owner, started and completed the work as per the schedule. He was on site the majority of the time both supervising his crew and performing the work. He kept me informed on a daily basis and was very helpful explaining the scope of work as it took place for removing the slab in my 2 car garage and pouring a new reinforced slab. The finished product has a professional looking appearance and the crew left a totally cleaned site. I'm very satisfied with the work and i recommend AA Outdoor Services for similar projects.d"
