As of January 2015, the professional installation cost for a new dryer vent ranges from about $110 to $235. This cost includes the price of a dryer vent kit, labor expenses, and miscellaneous materials and supplies.
The cost of replacing a dryer vent may be higher than stated if additional work is necessary. Many contractors charge additional fees for incidental repairs and modifications, as well as tasks such as debris removal and appliance relocation.
The cost of dryer vent installation by a bonded, insured and licensed professional may be on the high end of the stated scale. Getting bids from several contractors helps to ensure the best price.
