"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

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.

Depending on your structure, you may not need planning permission. Major excavation, anything that changes the external appearance of your home, or any construction that will affect your neighbors will need planning permission. However, no planning permission is required if you’re just converting an existing space into a root cellar.

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

There are several different steps in the pole barn building process. First, you’ll need construction plans, which you’ll use to obtain permits. Then, you can clear the land so it’s suitable for building and installing the foundation. Your contractor will frame the barn using large poles, then rough in the plumbing and electricity (if your barn has those elements) before finishing the interior, adding siding, and installing the roof. 

After that, they’ll finish up the electrical work and plumbing and add your windows and doors. You may have a few other finishing jobs to do like painting or waterproofing.

A contract should outline the scope of work, timelines, costs, payment schedule, and materials used for clarity and protection.
