"Mister Sparky is supposed to be an Electrical Franchise in the State of Florida. But, what they are is an "ORGANIZED CRIME Group" operating to defraud people from multiple offices throughout the state of Florida. This is NOT the case of 1 individual Contractor working without a license. My request to Angie's was for a license Electrical Contractor to have entered an Application for an Electrical Permit in the city of Miami Lakes, Florida where I live. A job that other local individual Licensed Electricians had quoted me $800-$900 dollars. But, I choose Mister Sparky because of being a Franchise group, I thought they would have been more reputable and professional and I paid them in full $4,152 on the day they came to my home. Jean, the electrician who came to my home and took my money on Friday August 8, told me they would enter the Permit Application into the city of Miami Lakes in 3 days on Monday 11, 2025. Since then, I have called numerous times to multiple phone number and NO one has called me back, including Bruce Howard Fort, Jr the person holding an Electrical Contractors License showing on the signed contract."

Subcontractors questions, answered by experts

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

The timeline for building a game room depends on the project’s complexity. Converting an existing room may take one to three weeks, while building a new addition or highly customized space can take several months. Factors such as permitting, material lead times, and contractor availability also impact the project schedule.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

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.

While some people are confident in their ability to replace concrete by drilling out the broken pieces and replacing them with bagged concrete, it’s possible to run into snags that make hiring a professional worth it. Trying to level concrete slabs can require special equipment, which can be pricey to rent and tough to operate. It's also crucial to contact your town's municipal office to ensure you are allowed to take on the project without a permit.
