GreenStream Environmental came to my home and conducted an inspection of the attic for mould. A few days earlier other workers had commented on the presence of mould and so I had to deal with it before adding insulation to the attic. The managing director was on time and very courteous. He spent about 10 minutes checking the attic and then informed me that a small amount of old water damage was visible on several rafters but that it was all dry and inactive. We concluded that this damage occurred when repairs and reconstruction had been done 20+ years ago. He recommended that I paint over the underside of several beams and then increase the insulation as planned. There was no charge for this very professional service. I would highly recommend using this company for any of the services they provide.
