"My dad is elderly and needed a new HVAC system. So I decided to find a person who could install a new HVAC system and we found Cody. Cody was very friendly, honest, and communicated very well. At one point he told us we could probably go another 3-5 years with the current system, but since my dad only has so many years left we told he to go ahead and install a whole new system in. He treated us like gold and even spent the time showing my Dad all the new features with the thermostat. I would highly recommend Cody for any repairs or HVAC needs you have."

Subcontractors questions, answered by experts

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.

While some people are confident in their ability to replace concrete by drilling out the broken pieces and replacing them with bagged concrete, it’s possible to run into snags that make hiring a professional worth it. Trying to level concrete slabs can require special equipment, which can be pricey to rent and tough to operate. It's also crucial to contact your town's municipal office to ensure you are allowed to take on the project without a permit.

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.

  • 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.

Many providers assist with obtaining necessary permits. Confirm with your contractor.
