Tipping contractors, builders, or general contractors is not customary or expected. Unlike many service professions where tipping is built into the payment structure, construction professionals typically charge a full rate for their services. However, you may choose to tip a worker for exceptional service, such as if they go above and beyond, stay late to meet a deadline, or work on a holiday weekend. Before offering a tip, it's a good idea to ask about the company's policy, as some prohibit their employees from accepting gratuities. If you want to show your appreciation for a job well done without giving a cash tip, consider writing a positive online review or offering to serve as a reference for potential new customers.

Most professional appliance removal companies will not expect a tip, but offering one is a good way to show appreciation for a job well done. A tip of 10% to 20% is a good idea if your professionals are working in the rain or snow, if they take extra care not to damage your walls and furniture in the removal process, or if they need to maneuver the appliance through tight spaces or up or down stairs to get it out of your home.

If a contractor is in breach of your contract, sometimes it is possible to collect damages for unreasonable delays. However, such claims can be expensive and difficult to prove. If there’s a way to complete the work and maybe negotiate for a discount for some of the inconvenience, that might be a simpler and cheaper way to resolve any disputes.

Aside from a professional light installation company, there are a few other pros who may be able to help you hang Christmas lights. Along with specialty holiday decorators, a handyperson near you can also hang Christmas lights (and can fix that pesky drippy sink while they’re at it). Either way, not all of these pros will offer the service, so be sure to call ahead and get multiple quotes before you hire.
