Insurance Backed Guarantees
The guarantees provided by Calibur Glass & Glazing Ltd are not insurance backed guarantees.
Calibur Glass & Glazing Ltd operates as an independent company providing direct guarantees to its customers alongside manufacturer warranties on the products supplied.
Guarantee Conditions
Guarantees apply to products supplied and installed by Calibur Glass & Glazing Ltd under normal residential use and are subject to reasonable care and maintenance by the Customer.
Guarantees do not cover damage caused by misuse, accidental damage, structural movement of the property, extreme weather conditions, lack of maintenance or work carried out by third parties.
Blinds & Window Warranty Limitations
Please note that the installation of blinds directly onto our window or door products can affect the validity of your warranty. The following conditions apply:
Screw-Fixed Blind Clips
If blind clips or brackets are screwed into the window or door frame, sash, or glazing beads, this constitutes a physical alteration of the product. As such:
• Any warranty on the affected window or door will be void.
• We will not accept liability for damage or performance issues resulting from such fixings.
• Any required repairs or replacements caused by screw-fixings into the product will be fully chargeable to the customer.
Push-In Blind Clips (Tension-Fit Behind Beads)
If blind clips are pushed or wedged behind the glazing beads, sitting against the sealed glass units, this also carries risk. In these cases:
• We will not accept responsibility for any cracked, shattered, or otherwise damaged glazing that may occur during or after the installation of these blind types.
• If glass breakage occurs where blind clips have been installed in this manner, all remedial work (including sealed unit replacements) will be chargeable in full.
General Advice
If you intend to fit blinds to our products, we strongly recommend using non-invasive methods such as magnetic, adhesive, or tension-fit systems that do not pierce or interfere with the frame, sash, or beadwork. If you are unsure, please contact us prior to installation.
Repairs and maintenance
Calibur Glass & Glazing will carry out all repair works using reasonable care, skill, and professional judgement in accordance with industry standards. Our warranty applies solely to the workmanship and materials supplied and installed by us as part of the agreed repair works. It does not extend to any pre-existing structures, installations, defects, or conditions that fall outside our scope of works. Where existing elements, site conditions, or previous installations affect the performance of the repair or limit the effectiveness of the work, we will inform the client and, where appropriate, recommend a suitable course of action based on our professional assessment. Calibur Glass & Glazing cannot accept liability for any additional defects, failures, or issues arising from or related to elements beyond the agreed scope of works.
Glass and Product Appearance
All glass units, frames and associated products supplied by Calibur Glass & Glazing Ltd are manufactured in accordance with recognised industry standards.
Due to the nature of glass manufacturing, minor imperfections such as small marks, blemishes, optical distortion or slight variations in appearance may occur. These are considered acceptable provided they fall within the tolerances set out in relevant glazing industry standards and do not affect the structural integrity or performance of the glass unit.
Glass units should be viewed at a distance of not less than two metres in natural daylight, looking directly through the glass and not at acute angles. Minor imperfections that are not visible under these conditions are considered acceptable and are not deemed a defect.
Similarly, slight variations in colour, tone or finish may occur between batches of frames, foils, trims or roofing materials due to manufacturing processes. Such variations are normal and do not constitute a product fault.
Calibur Glass & Glazing Ltd shall not be held responsible for perceived defects that fall within accepted industry tolerances.
