"We just had our kitchen completely renovated by Beverly Builders Group, and we couldn't be happier with the end result! Lawrence was our contractor and he fully brought our vision to life!!! My family and I went out of the country while the kitchen renovations were done and Lawrence took care of everything for us. He was super easy to get in contact with when we needed him or had any questions. He honestly went above and beyond for us and I loved how transparent he was about the job along the way. I've worked with other contractors in the past that weren't so honest and it was such a nice experience this time around. Emily was our project coordinator and designer and kept us updated daily on what was happening. We were always in communication with her and she overlooked our shopping list of all appliances so nothing was missed on our installation dates. Their team was amazing and I highly recommend them to anyone who wants the best! We were so happy with them that our master bathroom"

Bathroom Fan Installation questions, answered by experts

Installing additional vents or return air pathways and ensuring existing ducts are unobstructed helps improve airflow. A qualified technician can offer solutions to optimize your ventilation system based on room layout and needs.

Yes, most services include ductwork and venting to ensure adequate airflow. Confirm with your contractor.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Costs range from $150 to $400, depending on fan type and labor.

A bathroom fan lasts between five and ten years, depending on its quality, how it’s installed, and how often you use it. If you notice your fan is no longer working as well as it once did, consider replacing it before it stops working altogether. Installing a bathroom fan costs between $240 and $550.
