Close scratched-glass punch-list items without disrupting the schedule
Service for Project Managers who need to correct scratched glass, control unplanned costs, and release areas before handover.
Scratches often appear on the punch list when the schedule is already under pressure and several trades depend on release of the same work area.
Immediate impact
The observation prevents areas from being closed out, forces coordination among glazing, cleaning, supervision, and access teams, and can generate unplanned costs.
What can happen if it is ignored
If correction is postponed, replacement can interfere with completed finishes, affect handover milestones, and trigger responsibility disputes among contractors.
Technical cause of the damage
Abrasive cleaning, grit, or tools can leave lines that become visible near the end of the project, when the façade should already be closing out. The Project Manager needs to identify panes, responsible parties, dependencies, and the deadline.
Common alternatives and hidden costs
Postponing the open item shifts milestones; replacement reopens coordination with glazing, façades, and finishes. On-site restoration allows the correction to be integrated into the schedule without dismantling complete systems.
Benefits of evaluating restoration
- Intervention by areas compatible with the project schedule
- Defined scope and estimated times to coordinate dependencies
- Evidence of correction and closure of open items
- Work-front comparison versus dismantling and replacement
Service process
- We convert the punch list into work areas, estimate hours per square meter, agree on access requirements, intervene according to the handover sequence, and provide visual evidence to close each package.
Scope and limitations
For scratches, there is usually an approximate limitation of 4 to 7 cm from certain edges. The final scope depends on the system, glass type, access and assessment.
We do not work on broken, cracked, fractured or structurally damaged glass. We restore deep damage when the glass is not broken or cracked. Depth changes the work time and sequence, but it does not rule out recovery.

Frequently asked questions
Is the work performed with the glass installed?
Yes. We work with the glass installed as long as it remains intact and safe access is available, avoiding removal and reducing disruption to your space.
Can tempered glass be restored?
We restore tempered glass with superficial or deep damage as long as the glass is not broken, cracked, fractured or structurally compromised.
Does the glass become distorted or weakened?
The specialized process recovers the surface in a controlled manner without distorting the glass or altering its function. Before starting, we confirm the scope using the case’s technical information.
Can deep damage be restored?
Yes. We restore deep damage when the glass remains intact; depth determines the work sequence and time, but by itself does not require replacement.
How is the price determined?
It depends on the type and depth damage, area, number of panes, access, height, location, sector and volume.
When is restoration not possible?
We do not work on broken, cracked, fractured glass or damage that structurally compromises the glass.
What information do you need for an evaluation?
Damage type, location, quantity or area, access conditions and case-specific information. We do not request photographs in the first contact.
Is it worth evaluating before replacement?
Yes. Technical confirmation makes it possible to compare scope, timing, operational risks and direct and indirect costs against replacement.
What happens if a pane cannot withstand the process?
This is very uncommon because Grupo GNOVIA personnel are trained to restore glass using a controlled sequence. In exceptional cases, previously damaged glass may not withstand the intervention. If that occurs, we do not charge for the service performed on that pane; however, we do not assume the replacement cost of glass that was already damaged before work began. This condition is explained clearly before the work starts.
Do you need an on-site visit to confirm the service?
Not in most cases. We can confirm service remotely using the damage description, dimensions, glass type, location, and access conditions. On-site visits are primarily reserved for construction projects or projects involving a large volume of glass.
