"Jev, Richie, and Emily were all professional, and efficient. This bathroom was an old 70's bathroom with tile on the walls. We weren't sure what Jev would find, but he communicated with us every step of the way. He did a beautiful job. I would recommend him."

Unique idea to brighten a small bedroom- glass wall to the master bathroom
Before...
A personal spa - custom-made steam/shower cabin
After...
Another custom-made tiled shower cabin combines a remarkable selection of ceiling, walls, floor tiles, brushed nickel hardware, and crystal-clear shower doors.

"Mark was great from the start. I called on a Wednesday hoping to have work done in a short 3 week window. He happen to have an opening and working in my area on Friday. Mark gave me a 2 hour window and checked in to let me know he was on his way. He cleaned the chimney and installed the cap and flashing in about an hour. Everything looks great and no mess left behind. Mark has been very responsive to questions in timely manner. I would highly recommend Eastern Chimney to anyone who has chimney needs."

"LeakMasters was one of three bids we received. Jerry was responsive, thorough, and a pleasure to work with. He got on the roof, his measurements and estimates were spot on, he provided us with options for shingles, ventilation, and warranties. He always answered our questions thoroughly and followed up diligently. Once we agreed to the terms, we went forward very quickly. Jerry's large and experienced crew arrived early on a Saturday and the new roof was installed and the property thoroughly cleaned by 2:30pm. Amazing! And the roof is wonderful. We'd hire Jerry again and recommend him to anyone looking for a new roof."

"We hired Gage and his team to finish an expanded deck project abandoned by another contractor. Gage met with us and patiently heard our ideas, our concepts and immediately set to work making them possible. He was efficient, thorough, and most importantly, made our new deck safe and ready to be used in just five days. He and his team are consummate professionals and craftsmen, kind, friendly, attentive and patient. Gage was super communicative and checked in with us and provided updates every day of work, showing us what he’d been doing as well as bringing us ideas and new concepts. This level of customer service, professionalism and master craftsmanship is unparalleled in this market, and any homeowner would be lucky to have the chance to work with Gage, and we’re excited to work with him for future projects."

Bathroom Fan Installation FAQs, answered by experts

You should generally avoid using WD-40 on a ceiling fan. While it might quiet a squeak temporarily, it is primarily an anti-corrosion and water displacement agent, not a true lubricant, and can damage the fan's components over time. Most modern ceiling fans have sealed bearings and do not require oiling, so a squeak may indicate another issue. For fans that do require lubrication, it is better to use a light machine oil, 30-weight motor oil, or a lubricant specifically designed for ceiling fans.

Most ceiling fans have a lifespan of anywhere from five to 15 years or 10 years on average. Just how long your ceiling fan lasts depends on the quality of the parts, how much it’s used, and how well you maintain it. A fan with a weak motor that runs on the medium setting nonstop is likely to have a shorter lifespan compared to a fan with a powerful motor that runs on the slowest setting for air circulation.

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.

While wood stove fans are effective for improving heat distribution, they rely on the stove reaching a certain temperature to operate efficiently. If the stove does not generate enough heat, the fan may not start or may not move air effectively. Additionally, like any fan, wood stove fans cannot cool a stove or reduce its heat output—they only redistribute existing warmth.

The number of blades for your fan poses both advantages and disadvantages. Typically, the more blades on a fan, the better the air distribution and cooling effect, but this also means that your fan will have more wear on its motor. For small rooms, three-blade fans should work fine. For larger areas like living rooms, four or five-blade fans might be the better option.
