The electrical box on the house is 100 amp ( the licensed electrician that actually came and fixed the house said 100-amp is more than adequate for a 1300 square foot house a 100-amp box is more than enough for a 2600 square foot house) . This company said 8,000 for the upgrade ( not needed ) . We actually hired a electrician that is a licensed electrician not a handyman like this company sends out he said it was a faulty GFI in the garage and have had no issues . Thus company just wanted to rip off a disabled person because he figured I was stupid ."

Subcontractors questions, answered by experts

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

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

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.

Most commercial projects take 3-7 days, including curing time, depending on size and weather conditions.

While it can be easy to reupholster small items like outdoor cushions or pillows yourself, bigger projects are better left to the professionals. Hiring a professional reupholstery service is the best way to ensure your furniture is properly fixed, especially if you’re working with larger pieces, like couches, or high-end materials, like leather, where mistakes can be costly.
