About seven months ago my mom and sister decided to add an addition to the house... From the moment they walked in I loved their energy. They are top notch professional, Johnny on the spot, and most importantly they are trustworthy.

Excellent communication throughout the project and VERY clean and respectful of my home. I met with about a dozen contractors, they were not the highest or the lowest, but the quality is by far exceptional.

Home Additions FAQ — Lexington, SC

All renovations are an investment in your home, but adding heated square footage is one of the most reliable ways to add value. The best way to calculate this is to find the average price per square foot in your Lexington neighborhood. For example, if homes sell for $220 per square foot, adding a 200-square-foot addition can add $44,000 to your home's equity!
Yes. Any renovation that involves structural changes, foundation work, electrical wiring, or plumbing requires permits and county inspections to ensure code compliance. Palmetto Renovations manages the entire permitting process with Lexington County for every addition we build.
Most home additions take between 2 and 6 months from the start of construction to final completion. The exact timeline depends heavily on the complexity of the build, material selections, weather conditions (for foundation and framing), and the speed of local permitting.
Usually not! Because most of the structural work for a home addition happens on the exterior of your current home, disruption to your daily life is minimized. We only break through the connecting walls toward the end of the project, and we plan our schedule to keep your home comfortable and secure.
Home additions vary based on scope and finishes. Generally, labor and raw materials for a basic addition start around $50,000, with finishes adding approximately 50% to that base price. Expect to invest anywhere from $75,000 to well over $150,000 for complex master suites or second-story additions. We will help you determine the scope you can afford during the initial design process.
