Mine done just that on December 2023 at Irispro. Negotiated and arranged with Irispro management, whatsapp/email pic/pdf of insurance policy, car registration car, driver license (owner), ic (owner) car brand, model and year info, take a pic of your windscreen brand and specs (normally printed on bottom left/right of windscreen to ensure its the exact FWS model). They will liaise with Dr. Windscreen (co-incidentally, my previous windscreens of other cars also change with this windscreen vendor, excellent service) to check for insurance validity and insured amount. Irispro will inform the actual FWS pricing without tint to you. If you agree, you can go there and select a tint range or nego an Irispro tint that you want. They will add the tint pricing into the FWS claim.
Depending on the windscreen insurance amount, your cracked FWS must have existing tint if you want to claim tint. If you cracked FWS has not tint, cannot claim tint even if you insurance can cover them. In that case, any new tint from Irispro, you need to top up fully, the negotiated price. If got tint and the price of windscreen with your selected tints exceed the amount insured, you can top up differences directly to Irispro.
How to pay, you negotiate. For me, I select a tint range that I want and asked for pre-tinting. Dr. Windscreen will send FWS a couple of days in advance to the Irispro branch, they pre-tint FWS with the tint spec you requested in advance. Pre-tinting this way is better coz they no obstacle (vs tinting inside car) will swipe the tint very clean and clear of water bubble on a rack. If you want additional 7" black sunshade tint on top (I requested that too), they will add that extra layer on top for you (pricing, you negotiate). If there is an existing dashcam, I would suggest to leave the cable there and reinstall the dashcam again after the tint cured couple of weeks later.
Then on the day that you arranged for windscreen installation (with Irispro), Irispro will be holding the pre-tinted FWS and Dr. Windscreen mobile unit will go to Irispro branch indicated to install the pre-tinted FWS. Before they remove the FWS, they will tear a part of your existing tint and take pic of the cracks and the torn tint (insurance needs proof of crack and torn tint on the car to claim tint as well). Bring photocopies of your insurance policy, car registration card, IC, driver license and submit to Dr. Windscreen on site before installation. You must have all documentation ready (photocopy) if not, cannot install. Clear digital pdf and pics might also do although photocopy will ensure clarity but must be super clear and complete.
No need to wait for tinting after FWS installation. Install and go. Since you already pay Irispro (if tint exceed insured amt), they will handle financial and tint documentation transaction with Dr. Windscreen.
