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."

We offer complete satisfaction on every job. Hundreds of happy customers after more than 30 years in business. References available upon request. Go with a company that has the experience to back up t

"Len and his workers were excellent. Great customer service and great pricing. Len had great suggestions, and, in the end, Len renovated my entire condo from custom made fireplace with mantle and ceramic tile, high hats to cornice lighting, to back splashes, wainscoting, crown molding, chair rails, baseboards, drywall, everything. It looked spectacular and all my neighbors raved about it. No detail was left undone. His work is phenomenal, real quality old school worker who values and takes pride in everything he does. I referred Len to my sister, and he installed an entire front porch, and they love it. Always call Len first for any home renovations. Jackie Campo"

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.
