We specialize in the sale of fine antiques through high end auctions and estate sales.

GEORGE COSTOPULOS 339 - 227 - 7085 EMAIL costopulos@mac.com web site http://georgecoestatesales.com

"I hired George to sell the contents of my aunts estate because he was the most professional and knowledgeable of all the the estate sale companies and numerous dealers who I interviewed, . My aunt's estate had many quality antiques, jewelry, and household furnishing and I wanted the right company that would know what these items were worth and would have the following to get good prices. In the course of my research I found that George had been in the estate sale & antiques auction business for over 30 years and came highly recommended on many levels. He was written up in the Boston Globe antique section on many occasions and the national antiques paper "the arts and antiques weekly". I felt, at this point with such a wide experence in selling fine antiques and household items George would be the right estate company. He came to my aunt’s estate and went threw everything and found items that I thought were junk and I had planed to through away. Thank goodness he had the knowlege to recognize their value because he got a lot of money for these items. After George looked at everything, he photographed all the pieces that he thought would attract buyers to the sale and made a page on his website dedicated to my sale and it came out beautifully. He sent out over 2000 emails from his list of people who had attended and purchased items from pervious estate sales and auctions and also advertised on estate sale .org, which send out over 12,000 emails. He also advertised on Craig’s list. Prior to the sale he came to my aunts home and organized everything and set up jewelry cases with lights and by time he was finished the place looked like a show room. He schedule the sale on Saturday from 9am to about 2pm. The day of the sale there was over 100 people waiting outside. It was a bit chaotic at first but George and his crew handled the crowd with ease. After the sale, George explained that letting the whole crowd in, is a good strategy because it creates a buying pressure. He said people feel other people are looking over there shoulder wanting to buy the item they are looking at so they pay the price that George wants and everything goes very quickly. He also said that the people who come early have all the big money and are highly motivated to buy. Sounds complicated but he was right. George had five workers besides himself and they were very helpful and curtious, bring furniture and other items to peoples cars. The sale has a steady flow of people after the hectic first 2 hours with people buying items all day long and by the time he was finished most everything was gone and he made us a pile of money. I was so thankful we hired george to do this sale. Everything went perfectly without a hitch as he predicted. He is truly a professional and I have recommended him several times."

FAQs for electrical wiring or panel upgrade projects in Plymouth, NH

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
