"Robert and his team did a fantastic job removing (5) trees from my yard at a fairly reasonable price. They covered my pool before proceeding with any work. They're very efficient, polite, and left my property clean. Even my neighbor hired them on the spot. We're very pleased with their service and will recommend them to anyone. Two thumbs up!"

"I'm looking for more quotes just to see who can handle the jobs I have, but Pedro called me very quickly after I had set-up a HomeAdvisor. He was very prompt and respectful over the phone and spoke with me in an extremely professional manner. I would definitely recommend Castaneda's Tree Trimming service to anyone looking for Tree Removal or other arborist services."

"I had a landscaping design/build company until illness kept me from continuing. I felt like I was in good and knowledgeable hands when Rock came out for the estimate - he is an arborist so he understood exactly what I wanted. His crew showed up on time and were very professional with a very capable foreman who interpreted Rock's job description accurately, so the job was done perfectly and the place was clean afterwards."
