From the first time we popped into the showroom for a chat, to the final payment, everything about our conservatory roof replacement has been excellent. Everyone at Global has been both pleasant and professional. The price they quoted us was fair. All work started and was completed on time, and we had visits from the Project Manager almost every day. Although different teams were involved (roofers, electrician, plasterer) they all communicated with each other, so they all knew what was going on, and what our requirements were. They were great at keeping us up to date as work progressed, and we got a daily update before they left the site each day. Work was completed to a high standard, and they were very respectful of our property and always left the site clean and tidy. Having work of this sort done was a big investment for us, but we felt confident that they were looking after us throughout. We gladly recommend them to anyone considering a conservatory roof replacement. And now that the roof is done, the conservatory is much warmer and quieter.

So Glad we chose Global windows
Customer Service
I would like to take this opportunity of thanking Global windows for doing an excellent job from start to finish: After visiting the showroom which is nicely laid out showing all the different types of windows and doors and patterned glasses to help us make our decision Trevor the salesman – very knowledgeably having done it for a number of years and his recommendations on colours and door accessories were appreciated, the quotation was easy to understand. We were kept up to date with the installation date by David, which was kept to and was a shorter delivery time than other companies we spoke to. The scaffolders arrived the day before and were excellent, keeping the driveway clear so we could garage our car at night. The installation team Steve and Becks arrived at 8am on the day of installation and immediately got to work covering the carpets and furniture in case any dust was shed after taking out the old windows, it was like this for the whole 3 1/2 days they were here, they treat our home like they would there own and after each working day cleaned up to a high standard. On completion, the scaffolders arrived the same afternoon and took down the Scaffolding. Pat in the office was very friendly and made sure that all the paperwork went through and certification sent through with a few days. Overall I would recommend Global windows every day of the week to anyone wanting new doors and windows Great Job

Excellent company.
Customer Service
We decided to go with Global to replace our existing conservatory. We had a number of quotations from various suppliers and chose Global after visiting their showroom and meeting their representatives. They visited our property and following discussions to meet our requirements and their recommendations. Friendly outgoing staff, not pushy but professional. After a number of visits we agreed and start date was set. Although a number of months away, they arrived on the agreed date and all work was completed to our complete satisfaction and a high standard. We are very happy with the service we received and would not hesitate to recommend them or use them again in the future.

Hindsight's a wonderful thing!
Customer Service
Global have just replaced our French patio doors, and the difference is amazing. This sliding unit feels solid and substantial unlike the previous. Not the cheapest company in the book, but the attention to detail, product quality and the undoubted expertise of the two guys who did the installation make the extra few quid feel really well spent. I've a bit of a jaded outlook on the quality of current day customer satisfaction ethic, but would suggest that Global has given me hope. Great job.

Excellent service
Customer Service
The job was to install a Guardian roof on an existing conservatory. The workers arrived on time and completed the installation in the agreed timeframe and on budget. We were kept informed of who would arrive and when and also of any changes to the original schedule. Final inspection was immediately after completion and any snagging details were completed the next day. A professional service from start to finish.

New Guardian roof fitted to an existing conservatory.
Customer Service
Third time we have used Global. All the work was carried out speedily, on time and professionally from start to finish and could not be faulted. A special mention for Michael in Sales, Joe for overseeing the work, Ian and Aaron, (fitters), Craig (plastering) and Steve (electrician) who all worked tirelessly throughout. Global must be proud to have such great people working for them. Everyone arrived on time as promised and left the place tidy afterwards.

Great work all round
Customer Service
From the initial consultation about our front door and the help with choosing which to have fitted, to the finished job, everyone involved was very helpful and knowledgeable. The door is very strong and draughtproof, and the quality is first class. We are very pleased we chose this firm and highly recommend them.
