"The fence is beautiful. The problem I had is that our neighbor didn't go in with half the cost. He had someone to do the job cheaper. I stayed with this company and the guy told me they could put it in front of the old fence. So they saved time and labor plus haul away expense and did not give me much of a discount. I am a senior and on a fixed income."

"Security Fence and Gates did an excellent job on replacing my rod iron fences with a more contemporary design. All of the workers were very skilled and knowledgeable and did an excellent job in measuring what was a sloped area. I received many compliments on the fence. I appreciate the variety of both and color selection. The price was reasonable, and the time it took from taking measurements to installation was good."

"I just had my new backyard fence installed by CQ, and I couldn't be happier. I was referred by a contractor who worked on my house, and I trust. He was so right about this company. Their customer service is wonderful. Have to give a shout out to Daniella who I spoke to and made arrangements. She was awesome! it looked so nice when done that I'm thinking I need to expand to the side of the house with the fence as well. Liz W."
