"They repaired sheet rock and completely repainted my bathroom, doing an excellent, neat job. In addition, they repainted my front door, and it looks like new. When I hire a painter, I watch for the small things like removing hardware and light switch plates. This company performed great in all categories. "

At Generator Supercenter, we are committed to securing your home and peace of mind with back up power solutions. When bad weather hits or an electrical circuit malfunctions, a power outage is likely. When that happens, you can recover quickly if you own a reliable home backup generator. Once your generator is installed, you’ll need reliable technicians available 24/7 and capable of providing quick services. Generator Supercenter of New Hampshire provides experienced technicians for generator installation, repair, and maintenance. Benefits of working with our team: Full-service – Whether you need a new generator, or your current one is malfunctioning, we won’t leave until your generator is up and running as it should be. Convenience – If something goes wrong with your generator, you don’t have to worry about going out to buy a new one or to replace parts. We will come to your home or business and take care of it for you. Free on-site estimate – When you call us, you’re not committed to a service—our estimates are free, so you can meet with a member of our team to learn about your options with no strings attached! Unfortunately we do not do anything with portable generators or any brands not manufactured by Generac. We are also not a parts distributor.

"Matt Sanford and the team at Generator Supercenter were professional, knowledgeable and efficient when surveying my property. They spent quality time educating me on their generator product line and monitoring services. If you're looking for a superior product, company, and team to support you throughout our long New England winters, look no further!"

Subcontractors questions, answered by experts
  • Installing a new electrical meter box

  • Replacing your meter base

  • Replacing your service entrance cable 

The cost to install or upgrade an electrical meter box ranges from $100 to $650, including $50 to $250 for the unit. The meter base passes the power from your electric company to your panel. The cost to replace a meter base is roughly $50 to $250. 

Service entrance cables are electrical cables with multiple wires, bringing power from electrical companies to residential buildings. The cost to replace a service entrance cable ranges roughly from $1,000 to $1,500.

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

Common pitfalls include underestimating the cost of site preparation, overlooking permit and utility fees, and not setting aside funds for unexpected changes. Change orders during construction can disrupt your budget. It’s best to plan a detailed budget, obtain multiple quotes, and include a 10% to 15% contingency fund for unexpected expenses.

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.
