Whitney replaced the wrong outlets and forgot to pull permit for the water heater, causing me to fail re-inspection and incur fines. Once it became clear that I was asking them to fix a job they had already received money for, they became difficult to reach, repeatedly dropping my calls and not returning my messages for days. They refused to compensate me for the city's fine, refused to re-do the electrical work without charging again, and charged me again to pull the permit. They're never getting another cent of my business.

I asked for a discount due to the 2 times they had to reschedule. They said yes and it was going to be $99. Well the day a young man came he refused to work on it because it was old and he said unsafe. He gave me every song and dance to have me buy a new furnace. I said no I am getting a second opinion. I have had my furnace inspected every year that I have owned this house. Yes it's old but in good working condition. All the burners lit right up, the fan worked, and no dust. So this young pup did nothing. Then they have the balls to try and bill me for $99.
