Subfloor Repair and Leveling in Atlanta, GA — Fix Before You Install

Subfloor repair and leveling in Atlanta addresses the structural layer beneath your finish flooring — the plywood, OSB, or concrete slab that all flooring types are installed over. Problems in this layer cause squeaks, soft spots, bouncy floors, and premature failure of new flooring installations. We handle four main types of subfloor work. First, squeaky subfloor repair: subfloor screwing or gluing to eliminate squeaks caused by loose fasteners or delaminated plywood layers — the most common complaint in Atlanta's 1980s–2000s housing stock. Second, soft spot and rot repair: replacing water-damaged OSB or plywood sections caused by plumbing leaks, roof leaks, or window condensation — a significant issue in Atlanta's humid climate. Third, concrete leveling: applying self-leveling concrete compounds to flat out slabs that have settled, cracked, or were poured with humps and dips — required before any tile, LVP, or laminate installation. Fourth, subfloor build-up: raising sections or the entire subfloor to match adjoining flooring heights, or to install heated floor systems. Subfloor repair is not optional — installing new flooring over a compromised subfloor is the leading cause of flooring warranty voids and premature replacement.

Subfloor repair pricing in Atlanta depends heavily on scope. Squeaky floor repair for a single room costs $150–$400 for screwing and gluing. Replacing a water-damaged section of subfloor (one room, up to 200 sq ft) typically runs $500–$1,500 including materials and labor. Full subfloor replacement for a larger area or whole floor runs $1,500–$3,000+. Concrete leveling (self-leveling compound for 200–400 sq ft) runs $400–$900. Extensive concrete grinding and leveling for problematic slabs runs $1,000–$3,000 depending on the variance to correct. Most subfloor repair projects are assessed and priced during the same visit as the new flooring estimate, so you have a complete picture of total project cost before committing.

Metro Atlanta's housing stock creates predictable subfloor challenges. Georgia's expansive red clay soil shifts seasonally, causing concrete slabs to crack and settle — particularly in outer suburban communities where construction on unstable fill is common. Crawl space homes, common in older Atlanta suburbs and rural fringes, develop subfloor rot from ground moisture vapor and poor ventilation. Plywood subfloors in 1970s–90s Atlanta ranch homes often have delamination from decades of foot traffic and humidity cycling. Slab-on-grade construction, which dominates newer Atlanta suburban builds, frequently requires self-leveling for tile and rigid flooring installations because builder-grade concrete pours are rarely flat enough for modern large-format tile specifications. We encounter these issues in every area we serve, and our crews are equipped to handle all of them on the same project.
