What Goes Wrong

Where indoor court installs fail, and how to avoid it

Skipped Slab Testing

Laying a floor over untested concrete traps moisture vapour, which buckles hardwood and lifts tile adhesive within months.

Moisture Test First

The on-site assessment tests vapour emission rates and checks flatness before any surface system is specified.

Wrong Surface Match

Choosing a floor system by cost alone ignores load-bearing profile, meaning a sport tile rated for light use fails under basketball traffic.

System Matched to Sport

The written estimate names the surface, hardwood, sport tile, or polyurethane, matched to your slab condition and intended sport.

Early Line Marking

Painting lines before a surface has fully cured or acclimated causes peeling and forces a costly re-strip within the first season.

Lines After Full Cure

Regulation line marking is applied only after the surface has completed its full cure or acclimation interval.

No Barrier Membrane

Skipping a moisture-barrier membrane on a slab with high vapour emission readings voids most floor system warranties outright.

Barrier Where Required

Readings outside tolerance trigger a moisture-barrier membrane or slab grinding before the floor system is installed.

How It Works

Getting the subfloor right before any indoor court surface goes down

An indoor court is only as good as the concrete slab it sits on.

Request an Estimate

Moisture in a concrete slab is the most common cause of indoor court failure. Before any surface is specified, the slab is tested for moisture vapour emission and checked for flatness with a straightedge. Readings outside tolerance require a moisture-barrier membrane or slab grinding before the floor system is installed.

Surface options include maple hardwood on a floating sleeper system, interlocking sport tile, or a poured polyurethane layer. Each has a different load-bearing profile and acclimation or cure interval. The written estimate states which system suits your slab condition and intended sport, with no lump-sum figures.

Line marking is applied after the surface has fully cured or acclimated. Regulation dimensions are used for basketball, volleyball, pickleball, or multi-sport layouts as agreed. A final walkthrough checks line placement, surface flatness, and anchor points for any wall-mounted equipment against the written spec.

Common Questions

Questions about indoor court installation in California

  • How do I know if my garage or barn has enough ceiling height?

    The required clearance depends on the sport. The site assessment measures the lowest fixed point (beams, lights, HVAC ducts) against the play zone. That check happens before any flooring system is selected, so you know whether the space qualifies before committing to materials.

  • What happens if my subfloor is uneven or damaged?

    Uneven subfloors need leveling compound or structural repairs before any flooring system goes down. Skipping this step causes tiles to shift and hardwood to cup over time. The site assessment identifies the extent of prep needed, and the written estimate includes that scope so nothing is hidden.

  • What is the difference between modular tile, vinyl, and hardwood for an indoor court?

    Hardwood gives the most consistent ball response and is standard in gym retrofits. Modular tile installs faster and handles minor subfloor irregularities better. Vinyl with an underlayment suits spaces where leveling is limited. The right choice depends on the sport, the subfloor condition, and how heavily the court will be used.

  • Can one indoor court be set up for more than one sport?

    Yes, but the room must meet the ceiling height and floor area requirements of every sport you plan to play. Line layouts and net or post anchor positions need to be planned together before installation starts, not added later, to avoid conflicts between court markings.

  • What happens if I delay the installation on a worn or uneven floor?

    An uneven or deteriorating subfloor gets worse under foot traffic. Surface irregularities that need leveling compound today can develop into structural repairs if left. A floor that is already slippery or soft also raises the risk of injury during play, which is a more immediate concern than the installation timeline.

  • Is a DIY surface kit a workable alternative to a full installation?

    A basic kit does not address subfloor flatness, ceiling clearance, or anchor requirements for net posts. Courts installed without those checks tend to play poorly and wear unevenly. A full installation includes the assessment and prep steps that determine how the court performs and how long it lasts.
