Conservatory Roof

"A great service from Global from start to end. We had a few different quotes to replace an old conservatory roof and create a large opening between our living room/conservatory to make a large room and Global offered the best package. Every one of the skillsmen were professional, courteous, friendly and good-humoured - and great at cleaning up after themselves :) Glad we chose them as the finished result is exactly what I wanted. The Guardian roof gives so much light to what was a dark cold room - I absolutely love it. I would definitely recommend Global Windows."

Global Windows – Simply the Best

"Had 2 large bedroom windows and patio doors fitted. Patio doors needed walls chopping and some plaster work. Two men arrived and worked very hard, professionally and politely. Cannot fault them or the work they have done. Windows a massive improvement on the old ones. The patio door recommended by the company looks fabulous."

New composite front door and PVC patio doors

"Global Windows were excellent from initial enquiry all the way through to installation. At no point was anything too much for them. The installation was exactly what I wanted with the look and feel of quality doors. I now have a new front door and patio doors to be proud of. I will be back to them later this year for new windows to match."

Installing a conservatory

"This Company is superb and I cannot recommend them highly enough. All the personnel they used were smart, tidy and professional. Subcontractors were also of the highest quality. The work was done for a more elderly lady and every member of the team really looked after her and treated her with the utmost courtesy and consideration. All the work was to an exceptionally high standard and the team cleaned up each day after work. The company management team kept in regular contact with updates etc. A superb team and COMPANY."

Front Door & Patio Doors

Conservatory & Doors

"Very impressed with Global Windows. I contacted them regarding my 16 year old conservatory. After 16 years one of the doors has dropped slightly, I phoned for advice on how to adjust the door, the response was, don’t worry we will come out and adjust it for you. Not many firms will do that for something 6 years out of warranty."
