Thank you so much for all the hard work you have done at my house with your colleagues. I have been incredibly impressed with the work, the perseverance (in the mud and rain), the final result and with the invoice. It all looks very promising as the Canary reader (after having been reset to 0 yesterday morning) shot up to 231 but has been steadily dropping and reads now 166 and seems to dropping still (normal readings in the kitchen have been above 400 consistently). I know it is still early days and I will let you know what the final reading will be in the rest of the house once all has been settled.
I will certainly recommend you highly to anyone I know who needs radon-work done.
