It can work in a period house & if you get the colour right it can work in a contemporary home too’

We would like to thank George Clarke for highlighting that radiators can be a stunning piece of art, in a period or contemporary home. We have always felt the same and that’s why we love and are passionate about what we do.

PetalProof Super 8 Films at our workshops in Basildon

PetalProof Super 8 Films came into film us working for the morning!

We were approached by Joanne Colley of PetalProof Super 8 Films, a London based Super 8 film maker who wanted to film radiator restoration, which is of particular interest to her. Of course we were delighted to have someone show such interest in us & in what goes on behind the scenes here at Blast Spray & Polish LTD.

We showed Jo our workshops and showroom along with some of the fabulous radiators that we have the pleasure to work on.

Jo was dedicated, passionate at what she does & had a great professional way of working. She had a small hand held camera and took some great shots. It’s a certain unique style which would be appreciated by those who love restoration and super 8 filming. It has a certain distortion of movement and colour, it captures the essence of working with radiators in their true form.

Many Thanks Jo for spending your time on this project we love it and hope you all do too!! If you’d like to take a peak copy and paste this link below to view it.

We are highly skilled in manoeuvring very heavy cast iron radiators.It’s what we have done for years! We don’t ever get complacent.

We are very aware that each individual radiator that comes to us for restoration is a very important part of someone’s home interior.

So every radiator gets our full attention, careful handling and our expertise during every part of the restoration process through to packaging them ready for delivery or collection.

After each radiator has been restored and either spray painted or hand polished, we wrap them up in shrink wrap, and then finally wrap them with a thick layer of bubble wrap.This protects the surface of the restored radiators.Keeping them free from dust and damage.They are then suitable for upright travel.
