Lightning Defense, LLC

The Lightning Defense company responded quickly to re-install our pre-existing Lightning Protection System (LPS) after our roof replacement was completed. Lightning Defense personnel worked quickly, efficiently, safely, and were very professional, courteous and clearly explained everything. They told me that our LPS was up proper standards and met all the county, state and any federal related requirements. They re-certified our LPS. I'm very satisfied with the results.

John is very kind its like working with your father. He explained everything very well, showed me all the materials he was using. When we spoke on the phone he did the same. When he came out he showed me his license, insurance, that he is bonded and he had a book of photos of his work. He cleaned up very well after the job was done left no screws or anything behind. This was the best service Ive had with any company at any time.

They did a great job a a very good price. They arrived on time and finished quickly. Wires were all neatly run and hidden along ridges and downspouts. Very satisfied.

A seamless experience. John showed up promptly with an estimate and sent me a copy of his liability policy as promised right after the estimate. I hired them and they promised to be at our house between 11:30 and 12. They showed up at 11:45, exactly the midpoint of the estimated arrival window. John estimated the job would take three hours but they completed the work in a bit less. He ran the cables along the gutters so they are not visible unless you look behind the gutters. I hope never to test the system (do not want my home struck by lightening at al, thank you!). but the materials are all UL listed.

Outstanding job. They got right on the job and had it done in a couple of days. I would HIGHLY recommend Mr. Sherlock.

Very good experience, showed up on time for estimate, started project immediately, came back on time the next day and finished the job. We were satisfied with the explanation of the work and the products used. I highly recommend this company for this job.

The owner John Sherlock was very professional, knowledgeable and did the job very efficiently. Cleaned up after the job. His wife was with him, they are a great team. The price is unbeatable. Would definitely recommend him. He is a no pressure guy. Educates you on all the different products.

Very knowledgeable in field.

Highly knowledgeable, friendly, on time and it was an excellent experience.

Very good job

I was given the fact of what was needed. there was no pressure. suggested to talk with another company, which i did. i was given a song and dance which enriched my decision to choose LD. What would you do differently?
