What our customers say
Thank you Gary!! I’m extremely satisfied with the electrical work you did. This is the first time I hire contractor and did not have a bad experience. Very knowledgeable and the work meticulously perfect.
Gary Has done many jobs in our home throughout the years from electrical and construction. He has always been very honest and professional and very competitive with cost. Always does an outstanding job! Would highly recommend him to everyone!
Great work for extremely reasonable prices. Gary responded to my call quickly and came to troubleshoot and fixed everything promptly and provided very professional service. I have an electrician for life now. I hope you are around for a very long time to service our community.
Great service, very professional got the job done on time. Highly recommend
Absolutely the best, fast service you can rely on, quality you can depend on!!!
Excellent service from start to finish. Hillside GC they did a great job on my townhouse and they finished it on time. I’m so glad I found you guys. I highly recommend Hillside GC
Professional and efficient. We needed our garage to be upgraded with a grounded outlet for our ev charger. Since our rental home was grandfathered in with 1950s wiring which our landlords wouldn’t update, Gary found a way to install a separate circuit for our garage to also meet code. His initiative and diligence solved the issue for our situation and we are very thankful to him for that. On top of that, he also worked a Sunday with 2 other jobs before us. Its nice to know there are still people with a great work ethic like this. Thank you Gary.
