"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

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.

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

On average, the cost to transform your garage into a workshop is about $2,000. The overall project cost depends on the type of workshop you want to build and its size. Regardless of the type of workshop, you’ll still need basic workshop spaces and equipment such as a workbench, cabinets, and space for storage and for working.

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.

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.
