Is your subfloor showing signs of damage? At Houston Flooring Company, we specialize in professional subfloor replacement services that restore the critical foundation of your entire flooring system. Our comprehensive subfloor solutions typically range between $3 and $10 per square foot for materials, with expert installation labor adding $25 to $30 per hour to the overall project investment.



We expertly handle all types of subflooring materials—including traditional wood plank, engineered plywood, oriented strand board (OSB), and concrete subflooring systems. Our experienced technical team efficiently replaces damaged sections or manages complete room installations with precision, ensuring your new flooring receives the solid, level foundation essential for optimal performance and longevity.

With over a decade of specialized experience serving Greater Houston's diverse neighborhoods, we intimately understand the unique challenges local homeowners face with subflooring deterioration caused by our region's humidity, potential termite activity, and normal structural aging. Houston Flooring Company delivers thorough professional assessments that identify underlying issues, transparent pricing that respects your budget constraints, and expert installation techniques that protect your valuable flooring investment for years to come.

Our dedicated specialists address this essential foundation with the same meticulous attention to detail we bring to every visible flooring surface, ensuring complete structural integrity throughout your entire flooring system.

Common Grout Issues and Solutions

A strong subfloor is the backbone of any successful flooring project. When intact, it provides stability, prevents flexing, and creates a smooth surface for your finished flooring materials. Moisture damage is the primary enemy of subfloor integrity, particularly in bathrooms and kitchens. Water infiltration can lead to warping, rotting, and mold growth that compromises the entire floor system.

We recommend tongue-and-groove plywood or OSB (oriented strand board) for most subfloor replacements. These materials create a tight seal that distributes weight evenly across floor joists. For tile installations, an additional layer called an underlayment is essential. This provides the rigid, flat surface necessary to prevent tile and grout from cracking over time.

Common Issues and Diagnosing Them

Identifying subfloor problems early can save significant time and expense. The most obvious signs include squeaky floors, uneven surfaces, and springiness when walking across certain areas. More serious indicators include visible sagging, water stains on ceilings below, or musty odors that may signal mold growth beneath your finished flooring. We inspect these thoroughly before recommending replacement.

Vinyl flooring installations are particularly revealing of subfloor imperfections. Any bumps, dips or uneven areas will telegraph through this thin material, affecting both appearance and longevity. For concrete subfloors, we check for cracks, moisture issues, and proper leveling. Concrete requires different preparation techniques than wood subflooring but is equally important to address before new flooring installation.

Our Replacement Process

Our professional subfloor replacement process follows a systematic approach to ensure your new subfloor provides a solid foundation for your finished flooring.

Preparation and Removal

Before beginning any subfloor work, we conduct a thorough assessment of the damaged area to determine the extent of replacement needed. We then clear the space of all furniture and remove existing floor coverings to access the subfloor.

Our team takes careful measures to protect your home during this process. We set up containment barriers to prevent dust and debris from spreading to other areas of your house.

The removal phase involves cutting out the damaged sections of subfloor using specialized tools. We're careful to avoid damaging any electrical wiring, plumbing, or HVAC components that may run beneath or through the floor.

Selection of Materials and Underlayment

We use premium-grade materials for all subfloor replacements, typically selecting from:

• Plywood: 3/4-inch tongue-and-groove plywood for maximum stability
• OSB (Oriented Strand Board): A cost-effective alternative that still provides excellent structural support
• Cement board: For bathroom installations requiring water resistance

The underlayment choice is equally important for your floor's performance. Proper underlayment helps with sound dampening, moisture control, and creating a smooth surface for your finished flooring.

Installation Techniques

We begin installation by ensuring the floor joists are sound and properly spaced. If necessary, we reinforce or sister damaged joists before attaching the new subfloor.

We maintain consistent communication throughout the process, keeping you informed of our progress. For large projects, we can work in sections to minimize disruption to your daily life.

Our experienced team follows manufacturer specifications and building codes to ensure a properly installed subfloor that will provide a stable foundation for years to come.

Additional Services and Considerations

When replacing your subfloor, several complementary services might be necessary to ensure a complete restoration of your living space. Houston Flooring Company provides comprehensive solutions that address all aspects of your flooring project.

Plumbing and Electrical Adjustments

Subfloor replacement often requires modifications to existing plumbing and electrical systems. We carefully evaluate all fixtures and connections that might be affected during the replacement process.



For bathrooms and kitchens, we temporarily disconnect toilets, sinks, and appliances to access damaged areas underneath. Our technicians work with licensed plumbers to ensure all water lines remain intact and properly sealed after installation.

Electrical considerations include addressing any wiring that runs beneath or through floor joists. We take special precautions around electrical outlets and HVAC vents to prevent damage and ensure code compliance.

Cleaning and Maintenance Post-Installation

After completing your subfloor replacement, we implement a thorough cleaning protocol to restore your space to pristine condition. Dust and debris are inevitable during construction, but our cleanup process minimizes disruption to your home environment.

We use professional-grade equipment to remove all construction particles from the work area. This includes vacuuming exposed spaces and wiping down surrounding surfaces that may have collected dust.

Our team provides detailed care instructions specific to your flooring materials. We're available for follow-up questions about maintenance practices that will extend the life of your investment.
