"Carlos was extremely attentive to what I needed for my closets and provided great recommendations as we were brainstorming different solutions for how to customize for my new condo. He was prompt in all of our correspondences and transparent about the entire process. I have a couple of oddly designed closet doors that we had to work around; but when the drawers I was hoping for weren't available, Carlos said that he would custom build to what I wanted! We hit a speedbump with me catching covid, but Carlos was very supportive and still came through to complete 2 out of the 3 closets I contracted him for while I stayed at the far opposite end of the condo. I was so grateful for the enthusiasm, professionalism, and straight up care Carlos and his partner put into this project. And I am LOVING the work that's been done so far! Can't wait to get better so that we could start back up on the master bedroom closet!"

Stone Electric Corp. is owned and operated by Shaun M Stone. We are a family owned business focusing primarily on residential and commercial work. We believe making relationships and quality of work are the two most important factors when it comes to business. We come from a long family history of IBEW union trained electricians. My father has spent the last 40 years working in the industry. I myself plan to do the same. The customer always comes first. We work clean and always communicate the project to the best of our abilities to ensure our customer satisfaction! We are licensed and insured to complete your next home project!

"I had a disappointing experience with Stone Electric. They charged $2400 via Zelle for AC installation. When the electrician finally showed up, they could have been more professional and seemed to need more skills to handle the job efficiently. They installed a drain pipe higher than needed so drainage didn't occur; they left the freon gas pipe leaking. There was a six-month warranty, and when I called them to fix it the next day of installation, they kept blaming the head of the unit rather than the installation, which went wrong. Their unhelpful response and refusal to take responsibility were disappointing. I called Diakin company, and they discovered the real problem. I have to pay an additional $1100 to another company to refix the mistake they made. The unit was leaking water and frozen gas the day they installed it. On the phone, Mark, the head project guy, was rude and refused to take responsibility. Instead of a check, they took money via Zelle. Be cautious."

Generator Install questions, answered by experts

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home’s value, especially in areas prone to extreme weather and power outages.
