Drain Blockage

I would like to thank Mr Brace, he is a credit to your company. He came out to us with a smile and left us with one. He was very quick and efficient and cleared the outside drain blockage effectively. Deflo were called to come out on a Saturday afternoon and they were on the job within the hour. Will recommend them to friends and family. Thanks Deflo Ltd.
