We have the damp proof solution!

This completely breathable and impermeable exterior coating service could be just what your house needs.

Bricks are made to provide some form of weatherproofing for houses but over time the weather erodes this and the bricks start to let in water, starting a knock on effect of deterioration.

If left unchecked this causes untold damage to the house itself. Unlike DIY waterproofers, this will NOT leave a sheen on your walls.

This system is IDEAL for protecting listed or historic buildings. This cannot be bought in the shops

An amazing damp-proofing system!

As a demonstration of the coating's capabilities, we treated this ordinary house brick and waited just one day.

We then poured water on to it and this is what happened!

The compound forms a silicone barrier in the capillary channels (the billions of microscopic holes or voids within your walls that allow moisture to pass into the house), and leaves no sign of discolouration which helps to keep the surface of the walls clean.

After spending years attempting to remedy the damp and mould at the back of our house, NPA sorted it in only 3 days. This was 2 years ago. We have never had any damp since they did the work, so I am pleased to able to send this to you and say thank you and yes I would recommend you any day.

Mrs. "M" Glasgow, Scotland

Our home was in a sorry state before Never Paint Again repaired and weather protected the outside walls. Not only does the house LOOK better, it's warmer too.



Quite simply the best thing we ever did for our home! Years of damp, gone in a week, and 2 years later, still hasn't returned. Thank you!



I am writing to you all, to thank you profusely for not only the hard work your men put in, but also for the dramatic difference in our heating bills after the coating was applied. A recommended damp-proofing process.

Weatherproofing your outside walls without changing the look!

The fact that this coating makes no visible change to the wall, means that it can be applied (by us) on houses and buildings where, if the wall surface was painted, it would ruin the look of the house.

Once applied, using 2 generous coats, any rainwater will run off without soaking into the building.

It is fully breathable and does NOT "seal up" the house. Once applied, rainwater simply beads off like a teflon frying pan.

Suitable for modern homes as well as older or grade 2 listed buildings.
