see our review here four years ago for this firm. Amazing job again! Our bathroom fan was old loud and near useless. Worse yet we had black mold on the shower tiles. Nick ordered a lovely new window (removing the solid glass block window) and installed a new Whisper Quiet Panasonic fan. The new fan is so quiet I sometimes have to check the switch that it is even on! It is very effective and the new window is great. The mold is gone! Thanks to Nick's team led by the amazing Carlos! They came on time when they said they would and we are very happy with the results.
