I have personal experience with this company - their work is based on a concept of honesty and fair prices. Simply put, they do a WAY better job than their competitors. They will give you an estimate that is VERY close to what the actual cost ends up to be. No overestimating/overcharging here! This is because of their postive, up-front attitude in dealing with their customers.
A minority-owned business, they are located in NE, and recently opened up a new office off of Rhode Island Avenue, so as to be easily accessible to all of the DC Metro area. They do both residential and commercial electrical wiring - I got them to up the 'amp load' in my home and thier work was perfect.
