The Basics of Subfloor Repair and Replacement

Subfloors form the critical foundation beneath your visible flooring materials. We frequently encounter situations where damaged subfloors compromise the structural integrity and appearance of homes throughout Sacramento.


Subfloor Damage Assessment


When evaluating subfloor issues, we begin with a comprehensive inspection to identify the extent and cause of damage. Water damage is the most common culprit we encounter, often resulting from plumbing leaks, flooding, or prolonged moisture exposure.


Telltale signs include discoloration, warping, soft spots, and visible mold growth. We use moisture meters to detect hidden dampness that might not be visible to the naked eye.


Pest infestations, particularly termites and carpenter ants, can also significantly compromise subfloor integrity. Their damage appears as tunneling, small holes, or sawdust-like material.


Age-related deterioration is another factor we assess, as many older Sacramento homes have subflooring that has simply reached the end of its serviceable life.


Materials Used in Subfloor Systems


Plywood remains the most common subfloor material we work with, prized for its strength, durability, and cost-effectiveness. Typically installed in 4'Ă—8' sheets with thicknesses ranging from 5/8" to 3/4", plywood provides excellent support for most flooring types.


Oriented Strand Board (OSB) represents a more economical alternative that still offers good structural performance. However, it's more susceptible to moisture damage than plywood.


For concrete subflooring, we often apply a moisture barrier to prevent potential issues with humidity transfer.


Engineered panels that combine OSB with a plywood veneer provide enhanced moisture resistance while maintaining structural integrity. These hybrid options work well in Sacramento's varied climate conditions.

FAQs on Subfloor Repair or Replacement

We've gathered some of the most common questions our customers ask about subfloor repairs and replacements to help you better understand this crucial aspect of flooring maintenance.

  • How much does subfloor repair cost in Sacramento?

    Subfloor repair in Sacramento typically costs between $300-$800 for isolated damage areas like water damage patches or limited rot. Costs vary based on damage extent, accessibility, material type, and required labor. Repairs addressing squeaky floors may start around $200-$500 depending on the solution needed. Most companies offer free inspections and estimates, allowing precise quotes based on your specific situation rather than general pricing.


  • What is the average price to replace a subfloor in Sacramento?

    Complete subfloor replacement in Sacramento averages $2-$3.50 per square foot for materials and labor. For an average 1,200 square foot home, expect to pay $2,400-$4,200, though most replacements only involve a portion of the total floor area. Factors affecting price include subfloor material choice (plywood vs. OSB), removal/disposal fees, floor joist repairs if needed, and accessibility challenges. Homes with extensive damage from water, termites, or rot may reach $5,000+ for full replacement.


  • How long does subfloor replacement take to complete?

    Subfloor replacement typically takes 2-5 days to complete for an average room (150-300 square feet). Smaller patch repairs can be completed in 1-2 days. Whole-house subfloor replacement may require 1-2 weeks. Timeline factors include existing flooring removal, extent of damage, discovery of additional problems (mold, rot, joists), and drying time needed between steps. Weather conditions in Sacramento can also impact scheduling, particularly during rainy seasons.

  • Can you replace a subfloor without removing all flooring?

    Yes, subfloor sections can often be replaced without removing all existing flooring, though this depends on your flooring type. Hardwood and engineered floors installed with nails or floating methods allow for sectional work. Tile, glued-down materials, and vinyl generally require complete removal. Professional contractors can sometimes access subfloors from below through basement or crawlspace access. Partial replacement maintains budget and timeline advantages but requires precision to ensure seamless transitions between old and new subfloor sections.


  • Do I need to move out during subfloor repairs in my Sacramento home?

    Most subfloor repairs don't require moving out completely, though you'll need to relocate furniture and avoid using the specific rooms under repair. For extensive whole-house subfloor replacement, temporary relocation might be necessary for 3-7 days. Factors affecting livability include dust containment systems used, whether water/electricity needs shutting off, bathroom accessibility, and your sensitivity to construction noise and odors from adhesives. Professional contractors can typically work in phases to minimize disruption for occupied homes.
