At R. Campbell Construction, I take great pride in my work and work with you every step of the way to ensure you're fully satisfied with the end result. I know your home is your biggest investment and want to help you protect, maintain and increase that investment while creating your own personal space. I'm hardworking and always on time. Give me call and see the difference.

"I am so glad I found R Campbell Construction through your service. The bathroom remodel project went so well that I also contracted with Rich to renovate my kitchen. Rich and his team are of the highest caliber, conscientious, polite, timely and knowledgeable. In particular Rich Campbell has the experience and design sense to give great advice in making design decisions. Unfortunately I've run out of projects for him to work on but certainly recommend him to anyone seeking to modernize their bathroom or kitchen."

Vick B's General Contractors, LLC proudly offers top quality workmanship. Let our consultants assist you in translating your dream in to a comprehensive and affordable design. With nearly 20 years in the business, we have formed a family of tradesmen that are experienced, driven, and dedicated to establishing the look you have always wanted. We are capable of working with a budget for any project, whether it be for a home, office or commercial property. From painting and flooring to renovations and full custom remodeling, let our expertise and experience produce your vision.

"It was a great experience working with Vick. There was no way we would've been able to quarterback the project and have it done as quickly as he was able to, so 100% worth hiring him. Our project was gutting the kitchen and expanding it into the dining room (eliminating the wall to create one big kitchen), painting and new flooring throughout the 1st floor. He was able to get us on schedule QUICK and was good at communication. The job was subcontracted out, but the people Victor brought in were reliable, friendly, and hard working. Demo started 3/1 and the project was completed 5/3. A majority of the time was waiting on the appliances, then cabinets, then counters to come in so really all out of Vick's control. Once they were in though, Vick was quick to get the crew working again."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
