We recently had 8 replacement windows ( including a bay ) and new patio door fitted by Global and…read morethey did a marvellous job. Their representative gave us a quote without any pressure, advised us and didn`t once slate any other companies off, to try and gain favour and was professional throughout. Having instructed Global to do the work, the fitters did a great job. They arrived as promised and completed the work within the time frame stated. They were very friendly, efficient, neat and tidy and cleared up after themselves everyday. Nothing was too much trouble, and we were kept informed all the way about adjustments and snags, until things were resolved. The customer service and after care by their office has been equally very good - a brilliant service all round !! Linda and myself would have no hesitation in recommending Global. P.Addinell & L. Parker - very satisfied customers.

Owner's real name is Gary Higginson, although I have only ever known him under his pseudonym "Gary…read moreHiggs". I originally hired Gary to do two small jobs to the roof of my flat and on completing them successfully, Gary 'notified me' of another problem. He then used a gently-gently approach to gain my trust and once he had this, he advised me that if this job wasn't done then there would be serious structural implications for the entire flat and that it was incredibly urgent. Over 7 months, with unsightly scaffolding up around the property, we were held at ransom, bullied and essentially blackmailed in order to part with more money. As soon as I began to realize he was a fraudster, I confronted him about the lack of progress on the roof and where all the money I paid him had supposedly gone. I was initially met with aggression but then pretty soon after that, radio silence at which point he refused to speak with me. So in summary, he lied about the cause of the job (it didn't need doing), he then put up scaffolding outside my house for 7 months, the only work he ever did was to take tiles OFF my roof and just left the house bare, he then just got aggressive and then refused to turn up for work. I had to pay someone to re-tile the roof and take the scaffolding away. Please contact me before even thinking about working with this guy. DONT WORK WITH THIS GUY!!!
