Replacement bathroom window
I ordered a new unit for my bathroom window, I opted for free delivery as I wasn’t in a rush.
Unit arrived on the date specified and fitted perfectly.
Good price, top notch web site and communication.
Hopefully I won’t need to use you again but I’ll highly recommend you.
Many thanks…👍

Door double glazing panel
This is the first time in ordering double glazing panel and the website made this quite an easy task. Easy to input the dimensions and choose other extras for it.
Good delivery options and we choose the free one and the panel was delivered on time.
The panel was a perfect fit with no issues at all.
Good email communication throughout the process and would happily use them again.

Hi,
Thank you for your feedback.
We are sorry to hear that you were unhappy with aspects of your experience. However, we would like to clarify that replacement units are manufactured and delivered within 14 working days, as stated on our website. These timescales, along with our delivery and handling procedures, are clearly outlined to ensure full transparency prior to purchase.
Our glass is transported using purpose-built, racked vehicles and is carried unwrapped, also stated on our website. This helps us minimise costs, whilst doing our bit for the environment.
We appreciate you taking the time to share your comments, and your feedback has been noted.

You get what you pay for
You get what you pay for. The window units were cheap but they were poorly finished. One had marks on the inside of the glass and both units were covered in spots and smears of black sealant, which took a bit of effort to remove. They came without any protection, which I knew beforehand, so I had prepared an area in the garage putting some dust sheets down to protect the edges. However, the delivery guy put them straight down on the drive and then rang the doorbell and left. I had to pick stones out of the edges. I don’t know how they will perform in the long term, but as I said, you get what you pay for!

Great place to get replacement double glazed sealed units
If you need a replacement double glazed unit, look no further than SealedUnitsOnline. It's very easy to order the exact size and style you want from their easy to navigate website. The prices are very reasonable. I bought three units for my Mums front door. I wondered whether the Units would be damaged in transit but to my surprise they delivered them personally, which was amazing.

One star because I can't leave zero
One star because I can't leave zero. Shocking service. 2 months to deliver one small pane of glass. Never answered questions regarding delivery of whichthere were many. I will never use this company again. I even received two texts on separate occasions informing me my order for a double glazed unit had been delivered. I didn't order a double glazed unit.. Absolutely hopeless.

Very poor quality and late
Takes a long time to arrive and wasn’t given even an estimate day, it was simply lucky I was in. Delivery driver was really nice but the sealed unit was poor quality. The fitter had to cut down much of the overflowing black as there were thick lumps over 10mm in some places. I’ve have sealed units from other places and usually it’s flush and even so the glass sits evenly — but this was horrendous. Just so messy and was still tacky when it arrived you could sink your finger into it and any hair or dust got stuck to it.
Wouldn’t order from here again and would definitely not recommend it. Fitter was appalled by the quality and I just hope it doesn’t fail, I’d probably pursue a small claim if it does as I’ve evidence everything with photographs.

We take comments regarding product quality very seriously. All units are manufactured to the specifications selected at the time of order and are checked prior to dispatch. However, we are sorry to hear that you were unhappy with the finish described and the condition on arrival. Your comments regarding excess sealant and tackiness have been noted and will be fully reviewed with our production team.
We also regret that the delivery timing did not meet your expectations in terms of advance notification. While estimated lead times are provided at the point of order, we appreciate that clearer delivery day updates would improve the customer experience.
