I have found many good companies through Angie's list and this is another absolutely stellar company. I have an existing invisible pet system that was installed in 2000 around a 2.7 acre yard. My current dog has been particularly bad about digging in the flower beds and front yard. I recently had some landscaping done and did not want her to tear it up. I called Nathan when the landscaping was finished and he came out, took time to listen to all my concerns, and advised me on the best solution to the problem. He quoted me what I felt was a very reasonable price in a large yard and he and a helper were able to install the wiring and connect it to the existing fence that very afternoon. My dog was already familiar with the existing fence and quickly learned her new boundaries. It works perfectly and is exactly what I wanted. Both Nathan and his helper were personable, knowledgeable and professional. I would definitely recommend them to anyone wanting to install or repair invisible fencing.
