"Had Gridwise install a transfer switch and inlet box for our portable generator. We lose power a few times a year during wind events and got tired of running extension cords everywhere. Michael handled the install and walked us through exactly how to connect and start the generator when the power goes out. He was patient with all my questions. Permit was pulled and inspection passed first try."

"Just got a hot tub delivered and needed the electrical run to it. Mark and crew came out and installed a 50-amp GFCI breaker and ran conduit along the side of the house to a disconnect near the tub. Looked way cleaner than I expected. Passed inspection and we were soaking that weekend."

"Oscar and his crew did an amazing job on our small drywall installation, which included baseboard installation and painting in our garage. Oscar was fast, responsive, reliable and great to work with. Will be recommending Oscar and looking to work together again in the future for sure."

"Rigo's team has been working on our house for about a year. Projects ranged from installing hardwood floors, replacing all windows, adding recessed lighting, to full-scale remodels of three bathrooms and a rip and replace kitchen. Rigo is godsent when it comes to complex remodeling projects for novices like me. Not only does he do a great job, but he's also proactive. He anticipates potential issues and resolves them ahead of time. Any unexpected setbacks were met with grace and ended up getting resolved in the end. Rigo is receptive to feedback and takes pride in his work. He's also honest - if he doesn't have the skills to do something (which is rare) he mentions it right away and helps find a qualified tradesman to it correctly. Overall, I am very thankful we found him and I'll continue to hire him for any upcoming projects."

"SGK came out and replaced 4 of our windows earlier this year. The team was professional and helpful from the office staff down to the installers. We love our new windows and we won't hesitate to use SGK again for future projects."

Bathroom Fan Installation FAQs, answered by experts

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.

Wood stove fans are designed to operate quietly, emitting only a subtle hum from their motor. This low noise level ensures minimal disruption in your living space, allowing you to enjoy the warmth without distraction. The fan blades, which are engineered for efficient air circulation, contribute to the overall quiet operation. This makes wood stove fans a practical choice for maintaining a peaceful environment while effectively distributing heat throughout your room or home.

Identifying the source of noises is your first step to soundproofing a room without overspending. Generally, sound comes from inside or outside of the house. Inside noises include creaking floors, living noises like TVs in the living room, cooking sounds, or kids being kids. External noises generally include incremental weather, disturbing neighbors, and street traffic. Inside noises require you to soundproof floors, ceilings, and doors, whereas outside noises may require you to soundproof your attic, windows, and walls facing the streets.

It depends on your budget and cooling needs. Whole-house fans keep your home breezy by pulling in cool air and pushing out hot air. In places with milder climates, they can replace air conditioning. On the other hand, Attic fans focus on keeping your attic cool—not your entire house. Often, whole-house fans cost more than attic fans, with installation ranging from $600 to $3,600.

Yes, ceiling fans come with a few other features that help with function, style, and convenience. Multi-speed fans can give you specialized control over the airflow. Consider getting one with an integrated light to save ceiling space. Some ceiling fans come with a remote control that enables you to change direction without climbing a ladder. Of course, you can also consider installing a wall switch to enjoy that convenience.
