Walls, plaster and glass
Squash court walls, plaster, glass and doors.
Understand the surfaces and fittings that determine rebound, visibility, safety and the practical life of a squash court.
In short
A wall repair is successful only when the finished surface is sound, smooth, durable and plays consistently. Compare plaster, panel and glass systems by their construction, repair method, evidence and maintenance, not appearance alone.

Coverage note
This guide explains questions for a competent contractor. It does not approve a material, certify a wall or replace a condition survey.
The wall system is part of the court
A squash ball may strike a wall thousands of times over its life. The surface, substrate, joints, fixings, finish and surrounding structure all influence rebound and durability.
A court can look clean while still having cracks, hollows, loose panels, inconsistent patches, damaged corners, poor seals or unsafe fittings. Inspect the playing characteristics and the physical condition together.
Common approaches
| System | Potential use | Evidence to request |
|---|---|---|
| Hard plaster or render | Traditional solid-wall court or specialist wall refurbishment. | Product system, substrate preparation, thickness, curing, repair method and rebound consistency. |
| Panel system | Manufactured wall construction or replacement of damaged sections. | Panel specification, joints, fixings, impact resistance, repairability and compatible finish. |
| Glass back wall or enclosure | Visibility, spectators, events or a brighter visual connection to the facility. | Glass construction, safety standard, thickness, doors, fittings, seals, cleaning and replacement route. |
| Paint or coating | Refreshing a sound wall or completing a prepared repair. | Compatible substrate, reflectance, durability, impact resistance, preparation and future touch-up method. |
Squash court plaster
Armourcoat lists racket-court plaster systems for fives, rackets, real tennis and squash. Its Squash product should be treated as a specific system with its own preparation, application and maintenance requirements, not as generic decorative plaster.
A contractor should explain whether the existing substrate is suitable, how moisture or movement will be managed, how corners and junctions will be treated, how long the court remains closed and how the finished wall will be inspected.
Glass walls and doors
- Check panels, doors, handles, hinges, seals, protective edges and visible fixings together. Replacing a pane may not resolve movement or a damaged support.
- Ask for the safety-glass construction, thickness, relevant standards, replacement process and the competent person responsible for installation.
- Keep glass clean without creating a slippery floor or residue. Make sure visibility does not introduce glare or distracting reflections.
- Confirm that doors, locks and clearances work for the intended users and match the applicable court requirements.
How to specify a wall repair
Describe the wall type, defect, dimensions, location, court use, access, photographs and any previous repair. Ask the contractor to separate preparation, removal, repair, plaster or panels, painting, glass, fittings, cleaning, inspection and aftercare.
Do not accept a vague promise to make the wall look new. The handover should explain what was repaired, what remains outside scope, what cure or drying period applies and how the operator should monitor the work.
