Had my roof and my neighbours roof (two semi bungalows) cleaned this week by NII Clean.
The weather was atrocious for the job on the first day with frequent sleet and rain showers and cold throughout but I have to say the lads never stopped. The job was done very professionally and unlike so many tradesmen they cleared up the debris and washed down facia and guttering etc and brushed up, leaving both houses the way they found them. A pleasant and helpful team and I would have no hesitation in recommending them to friend, family member or stranger.
