"No matter what problem you have, Clint is the man for the job! He not only fixed the plumbing issues I discovered during a remodel but was able to fix the electrical issues, flooring problems, install the cabinets, cut and grout backsplash tile, and fix a handful of minor issues that came up along the way. Clint is on time, dependable, courteous and respectful of your property - he even cleans up afterwards! I could not have completed this project without Clint Hatcher and highly recommend him to anyone who needs work done - you will not be disappointed!!"

"My initial need was 2 bathroom fan repairs, but after quickly solving that problem, Brian did additional electrical projects in my basement. This job was not listed, but Brian stayed and installed task and room lighting. He did a great job."

"THANK YOU to the two men who replaced my fence six posts and a section of pickets yesterday. They worked well together. They listened to me before and after their work. They worked steadfastly through the morning. Much appreciated here. If I were their employer, I would keep these men."

Bathroom Fan Installation FAQs, answered by experts

A ceiling fan can become unbalanced for several reasons. Common causes include an accumulation of dust and dirt on the blades, which adds uneven weight. Over time, hardware like screws and fasteners can loosen due to wear on the blade holders. Other potential issues are damaged or bent blades or blade arms, worn-down parts, or an incorrect initial installation.

Exhaust fans push air out of spaces, removing moisture, heat, odors, and pollutants. They vent air outside through ducts, preventing mold and improving air quality. Unlike ventilation fans, which circulate fresh air in and out, exhaust fans focus solely on expelling unwanted indoor air.

While it may seem like it makes sense to put a fan in the attic to cool it down, it won’t be as effective as installing attic fans. Ventilation installed near the peak of the roof, whether passive (just allowing heat to escape) or active (drawing the air up and out) will be more effective at cooling the attic.

While ceiling fans shouldn’t get loose over time, they still can—especially if they’re installed incorrectly. A wobbling or tilted ceiling fan can shift the screws out of place, causing it to loosen and become a fall risk. It’s important to tighten screws and balance blades as soon as you notice that they’re misaligned or uneven to prevent the ceiling fan from loosening further and becoming a hazard.

The square footage of your room will dictate the correct ceiling fan blade size. For example: 

  • Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

  • Rooms up to 175 square feet require 42- to 48-inch fans.

  • Rooms up to 350 square feet require 52- to 56-inch fans.

  • Expansive spaces over 350 square feet need a fan larger than 60 inches.
