Excellent responsiveness in communication. Excellent work quality. Would recommend.

The technician arrived on time, was very neat and clean, and very professional. I will always use Mister Sparky for all my electrical needs.

While the electrician arrived on time and was clean and courteous the pricing was very high and we unfortunately could not agree to purchase their services. Over $500 for an estimated 2 hour job, requiring only $40 of materials from the vendor!
