Protect final project quality from rainbow-like stains
Iridescence diagnosis for project directors who need to decide between restoration and replacement using technical and financial criteria.
The façade or windows show rainbow effects that affect visual uniformity and raise questions about defects, contamination, or chemical attack.
Immediate impact
The decision affects the budget, project reputation, and acceptance by the client, investor, or supervision team.
What can happen if it is ignored
Replacing without a diagnosis can consume contingency funds and create new operations; ignoring the effect can compromise perceived quality.
Technical cause of the damage
The rainbow effect can result from deposits, chemical residue, cleaning products, or surface alterations. Identifying the cause protects the investment decision and helps avoid unnecessary replacement approvals.
Common alternatives and hidden costs
Ignoring the effect compromises the final appearance; glass replacement consumes contingency funds and adds contractual risk. Restoration provides a measurable alternative before turning an optical condition into widespread replacement.
Benefits of evaluating restoration
- Identification of the probable cause
- Technical criteria before authorizing replacements
- Protection of investment and reputation
- Evaluation using representative samples or areas
Service process
- We select representative areas, document appearance and lighting conditions, define the scope by façade or level, perform the correction, and review uniformity from the project’s acceptance viewpoints.
Scope and limitations
Iridescence does not have a single cause. We identify whether the effect comes from deposits, chemical attack, or a surface alteration and apply the appropriate sequence to restore uniformity and clarity.
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.
