    It was a very positive experience working with BST. They were able to exceed expectations across the entire customer experience. We were pleased with their pleasantness, responsiveness, professionalism, and best practices from taking note of the requirements to performing the work until it was done. I highly recommend using BST and plan to do so again when upgrading a different part of our home.

    Darren and James brought my house up to current building codes adding GFI's to the kitchen, garage and basement. Repaired and brought up to code my wiring on my air conditioning. Converted two fuse panels to circuit breaker panels. Diagnosed an electrical problem in my hallway and restored lighting. Added new electrical for a living room ceiling fan, Kitchen Microwave, Dishwasher and door bell. Installed 3 out door security lights and repaired/replaced a older existing one. Every step of the way (I had a three phase project) Darren Carroll's entire staff was polite, accommodating and available by phone, text or email. Their knowledge of their trade, their professionalism and their attention to detail is the reason why you would want to consider this company for your electrical needs. The cost for this extensive project upgrade to a residential property was reasonable and worth every penny. They left the site after each phase, neat and clean. Any debris left behind was disposed of in my dumpster while it was on site. Some debris needed to be handled through the St. Louis County Recycling program and that was separated and neatly organized for me. You have every aspect of your project covered: Professionalism, Knowledge, Communication, Availability, Response and Value.
