I am a first timer so *hello*
My house was built in 2000 by Westbury homes (now Persimmons). An air brick just under the damp course of my back door leading into the garden has an inserted grille which has broken and in need of replacement without having to remove the whole air brick. I have measured the outside of the remaining air brick end to end which I have 216mm x 70mm. None of my local diy stores supply the same one. Can anybody enlighten me on where I can find a replacement?
Thank you. Scott
