The glass units were not wrapped-…

The glass units were not wrapped- protected in any way. One unit was cracked across the unit on one side.
Took 6 weeks to be delivered.
Cannot speak to anyone about this situation- no one answers the phone.
So ordered a new unit from another company. Delivered in 5 days . Wrapped up and protected.
And 1/2, the price.
Not good.

Hi Martin,
Thank you for your feedback, and we are sorry to hear about your experience.

We take all reports of damaged or faulty units seriously. Our glass is transported in purpose-built, racked vehicles and is delivered unwrapped as standard, as stated on our website prior to ordering. All units are finished with black edge tape for protection during handling and installation.

We are sorry to hear that one of your units arrived damaged and that you were unable to reach us by phone. This is not the level of service we aim to provide, and we understand how frustrating this situation would be, particularly alongside the longer lead time you experienced.

If you have not already had a response, please follow up with our team so we can ensure this is reviewed and resolved as a priority.

Thank you again for taking the time to leave your feedback.

Excellent service, production and delivery of bespoke glazing units.

The ordering process was really effective, enabling bespoke sizes and configurations to be created. Production and delivery were similarly swift and I was kept updated throughout the process. Definitely recommend SealedUnitsOnline. Very impressed.

Panels were as ordered but delivered late

The ordering process was straight forward and clear, their prices competitive and the panels that were delivered were exactly as ordered.
However, I paid for a premium delivery and they arrived late leaving us boarded up for longer then necessary, hence the loss of a star.

Thank you again for your feedback and support – we appreciate your recommendation and hope to provide a smoother experience next time.

Glass was delivered not wrapped just sheet of glass with address sticker on
Delivery man handed it to my daughter at the door and she realised it was rough on edges and in taking it had cut her hands -both badly
I emailed the company and sent pictures as requested and haven’t had a response
Completely wasted money - glass is no good to me as dangerous

For safety purposes, the sealed units are finished with black edge tape to help protect the perimeter of the glass during handling and installation. We are sorry to hear about the concerns you have raised regarding the condition on arrival and any injury sustained.

Easy and to specification

Good glass, easy to use website, lots of options and arrived on time and to specification for a fraction of the cost of getting someone in to change the panel.
