Subcontractors questions, answered by experts

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.

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.

No, builders and general contractors don’t expect tips. In fact, some companies may prohibit their employees from accepting client tips. If you want to show gratitude for a job well done, consider writing a review of your builder or contractor or agreeing to be a reference for potential new customers.
