At Precision Home Remodeling, our foremost goal is to provide clients with a multifaceted expertise, supreme quality, extensive knowledge, and unmatched professionalism, all complemented by extraordinary customer service. We are committed to elevating your home renovation journey into an exciting and rewarding adventure.

"I am very pleased with the work done on our home by Precision Home Remodeling. We had a leak from our air conditioner with severe water damage to 2 bathrooms, master bedroom, and hall. Kris from Precision Home Remodeling helped us to negotiate with our insurance company to get double the initial amount they offered for the repairs. Kris was able to give us a reasonable bid for the home repairs plus for additional work we needed for roofs on part of our home and flooring with baseboards throughout our house. We also requested a new window that other contractors had been unable to replace due to the restricted space around the old window. Kris also had great recommendations for a new mantel that included painting of old bricks and some new tile work around the fireplace. Our home is old and Kris from Precision Home Remodeling authorized extra work to paint our ceiling, replace wood in our patio for the new roof, and leveling of our floors. We are very happy with the final results."

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.
