"From start to finish Steve was friendly, professional and had no problem helping us through every step of the process. Steve managed to keep the job site meticulously clean, kept to his promised timeline and was mindful of our budget. He has a great artistic eye and was able to make necessary design changes that took the job to the next level. The fireplace he installed is a STUNNING show piece with a complete shiplap surround, a beautiful handmade wood mantle, custom iron brackets and shiplap that continues across the entire back living room wall. Steve's attention to detail, talent and care for what he does shines through and we couldn't be happier with the end product! We are excited to have him continue our renovation process by remodeling our kitchen and other living space projects. We would highly recommend Steve to anyone we know. We were lucky to find him!"

"Tim and his crew are amazing. They built me an awesome deck!! From the beginning of the project to end I was thoroughly impressed. His quote was timely and fair. I’ve heard of so many horror stories about contractors so i was so pleasantly surprised at how great this experience was. The work began quickly and the workmanship is incredible. These guys know what they’re doing. Tim is so professional. He is prompt, he communicates everything in detail and really pays attention to detail in the work. He’s also a really nice guy. His crew is polite and work so hard. They’d get here and never stop working. Maybe 5 minutes to eat a sandwich. I plan to hire Tim for future projects. No question about it! Highly recommend."

"Paul O'Regan was a personable and professional pro. I hired him to build an in-law addition onto my son's house. I would not hesitate to hire him again. He was always available to answer any and all concerns I had during the build."

FAQs for garage remodeling projects in Londonderry, NH

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.
