Second-Story Additions
Adding a full second floor to a Bergen County ranch or one-story home — foundation reinforcement, structural framing, new roof, plumbing stack, electrical, and finish work. Major project; major value-add when the lot does not support sideways expansion.
Going Up When You Cannot Go Out
Second-story additions are common in Bergen County where lot coverage and setback rules limit ground-floor expansion. They are major projects: roof comes off, foundation may need reinforcement, structural framing supports new load, plumbing stack extends, electrical service often upgrades, and the household typically lives elsewhere during the build.
- Foundation evaluation and reinforcement
- Roof removal and structural framing
