New for old as good as new
25 year old house glazing and 15 year old conservatory in south facing sun exposure takes its toll on sealed units. Getting replacements for failed units on a DIY basis for size and appearance is key and Sealedunitsonline have been great suppliers for a couple of years now. Good contact before manufacture to get exactly what you need give confidence

I ordered a one double glazed unit
I ordered a one double glazed unit a few months ago ago. I was happy to wait just over 3 weeks to get a free delivery cost. The dimensions of glazed unit was exactly to my dimensions even although it could’ve been + or - 1 or 2mm.
Delivery was good by their own van /driver. So overall a very good experience and would definitely use this company again and recommend them 100%.

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!
