Glass grinding – a smart alternative to replacement
Watec Solutions offers professional glass grinding, sanding and polishing – a specialized service developed for contractors, or private individuals, who want an effective and environmentally sound alternative to glass replacement.
























Damage to glass in construction projects
The increased use of glass in facades, balconies and railings has made damage to glass surfaces a common challenge in new construction projects. Typical deviations include:
- Scratches and nicks – caused by accidental contact in the final phase of the project
- Mineral-based tarnishing – as a result of runoff from concrete, mortar or chemical impregnations
- Burnt-in deposits and coatings – which cannot be removed with conventional window cleaning
These damages are often cosmetic, but they reduce the perceived quality upon handover – and trigger demands for repair. Our solution is targeted: repair rather than replacement.
Glass grinding and polishing – functional and time-efficient method
Watec Solutions uses a specialized method for glass grinding and polishing that:
- Removes scratches, tarnish and deposits
- Restores the optical quality of the surface
- Preserves the integrity of the glass without reducing strength or durability

Our process uses appropriate chemistry and abrasives developed specifically for architectural glass. This provides documentable results without the need for disassembly or replacement. We refer to this as technical glass grinding – a precision work that is different from traditional window cleaning.
Typical applications and surfaces we renovate
- Windows and facade glass in residential and commercial buildings
- Glass railings and balcony glazing
- Glass surfaces in common areas, stairwells and entrances
Causes of damage include physical impact during installation, post-work with dust and particles, and chemical stress from runoff from facades.
Integration into the construction process – before and after handover
- We assist in all phases:
- Before handover: Registration, reporting and correction of glass deviations
- After handover: Coordinated follow-up directly with end customers/residents

- We have systems for:
- Inspection and assessment of the nature of the damage
- Technical feasibility in a cost-effective manner
- Communication with the responsible project manager
Environmentally friendly and efficient
- Replacing entire glass surfaces entails:
- High material cost
- Logistics challenges
- Increased greenhouse gas emissions (transport, production, waste)
- By choosing to repair existing glass, you achieve:
- Considerable cost reduction - compared to new purchases
- Reduced environmental impact – lower carbon footprint for our customers
- Higher customer satisfaction – due to fast and discreet execution, which means our customers use our services time and time again
Operation and maintenance – also for existing buildings
We also undertake assignments after the construction phase, as part of a maintenance strategy for:
- Residential building
- Office building
- Combination buildings and commercial properties
Common defects include tarnishing of patio glass, older scratches and surface deterioration. Our glass restoration restores the clarity and aesthetic value of the surface without structural intervention.
