Reading the positive reviews here put me at ease with dealing with the right person for the job, which is why I chose Joel at Marshal Electric.
There have been droplets of water from condensation coming down from the bathroom exhaust vent during the winter months, so much so, that part of the ceiling around the exhaust fan was wet. Apparent ceiling damage and mold would be imminent.
Joel came by and took a look at the whole thing and it was obvious that the duct work itself needed to be replaced and well as the positioning of how the duct vents up into the attic and out to the roof. The previous owners/builders who had set it up was done poorly and inefficiently. Basically the whole thing needed to be redone and done properly and this is exactly what Joel had delivered.
In addition, he provided a new super quiet fan which now performs much better than the previous one I had. More importantly, I don't have to worry about condensation and leakage problems as he re-did the duct work and sealed everything up properly.
Joel was very efficient with his time, did a great job, cleaned up properly afterwards, and charged a fair price. I would definitely recommend him.
