"Flavio is very good at what he does. He remodeled both my bathrooms for well under what other large stores and boutique folks quoted for. His team of plumbers, plasterers, electricians and painters did an amazing job at budget rates. I would definitely hire again."

"We had a complete front entry remodel done. The project involved tearing out old front stairs and building a new entryway with awning. The project came out beautifully!! Even better than I had imagined. Jeff and his team were great to work with and very talented. We really could not be any happier with the results."

"Every step of the way was above expectations. Scheduling was easy, I was notified of ETA, and Al, our technician, was prompt and thorough. We needed our gas fireplace cleaned, and the job was done thoroughly, carefully, and efficiently. Our 25+ year old fireplace now functions perfectly and looks amazing. Can’t beat the price. 10/10 recommend."

FAQs for garage remodeling projects in Portsmouth, RI

A garage apartment represents a valuable addition to your property when properly constructed according to local regulations. The potential benefits include additional living space for family members, rental income possibilities, and increased property value. 

Your specific return depends on local housing market conditions, construction quality, and ongoing maintenance. Consider consulting with a real estate professional regarding potential returns in your neighborhood.

Building a garage apartment requires multiple permits, with basic residential garage permits starting at $74 in most locations. You'll need separate approvals for structural elements, electrical systems, plumbing installations, and mechanical components. 

Many jurisdictions also require specific approval for accessory dwelling units. Contact your local building department early in your planning process to understand all requirements and associated costs.

Converting an existing garage into living space presents an alternative to new construction. The feasibility depends on your garage's structural condition, foundation type, and local zoning regulations. Key considerations include insulation requirements, utility connections, and moisture control. Research local codes thoroughly, as many municipalities have specific requirements for garage conversions.
