We recently had our windows and door replaced by Global. Our experience was second to none. They have a great team, from sales to the fitters and any of the staff we dealt with during the process. They might be a little more expensive than their competitors, but it was money well spent for the finish, product and peace of mind. I would have no hesitation recommending Global to others after our experience.

We need to replaced the guttering and soffit on our semi detached house. A Global rep gave us al the information we needed, using pictures from previous jobs to help us see what was going to happen.We made or choice and once the work started the 2 Global workers did an excellent job. They took a few days, and kept us informed about what they were doing. During the work it was also nice to get a call from the Global offices to ask us were we happy or did we have any issues. We can honestly say we are totally satisfied with the result. We are 100% happy to recommend Global for this type of Gome improvement.

Highly recommend Global Home Improvements for window installation. I only needed one window, but this was still not a problem with Global as it is with many other window installation companies. From the 1st point of contact, through any queries I had, to installation, it was all seamless. I love the new window, looks great but is also so sturdy and secure with a fantastic warranty. After installation, the place was left spotless. I will definitely be a returning customer to Global when I need to get windows in the future.

Eamon Fitzpatrick

My windows & doors were installed in 2017. A patio door eased it's way lightly out of alignment, possibly due to being a heavy triple glazed door. I rang Global about 11am, as I could not lock the door. They had an Engineer out to me, who adjusted a hinge grip, and the problem was fixed. By 3pm, the same day! I went to Global originally, as I knew they are a 2nd Gen family business, that manufacture the windows, & not just a sales outlet, so the buck stops with them. My particular job included, changing a door opening into a small wall & window, getting rid of garage doors to be replaced by a brick wall & window, & on another window space, we wanted to lower the brick level on the bottom end, for a deeper new window space. The Global price included all this additional required building work, and their works crew did it all. Perfect!

I recently had Global windows replace three windows and my front door. The experience was excellent from start to finish. The salesman and the team both on and off site were efficient and professional, the various necessary appointments made were kept at the stated time and date. They answered any queries or concerns I had clearly and precisely, and cleaned up after themselves ! All in all a great job.

I phoned Global to ask would they install new windows and doors in all the rooms on the ground floor of our house. A representative arranged a meeting and called to the house. He took me through everything: showed me all the options for the windows and doors and helped me select.Two weeks before anticipated, Global phoned to ask could they install the windows and doors the following week. I was delighted.Two men worked 5 days. They asked questions if questions arose, or I could ask them questions, no problem. Each day they cleaned the room and put any furniture they had moved, back where it belonged.And when they finished at the end of the week, they polished all the windows and doors, explained how they opened and locked, and left the house in shining order.The Sales Representative and two men who carried out the work were very accommodating and a pleasure to deal with.And now we have wonderful Global windows and doors throughout the downstairs of our house. They give this 35-years- old house an enormous lift. We face winter fortified.All in all, an excellent experience.

After Much deliberation and research, we chose Global for our Windows, doors and sunroom replacement. They have excellent reviews and are the only company with a 20 year gaurantee! I'm so pleased to say, we were not disapointed!From the initial, in dept sales consultation with Andrew to the final finished product, the quality of the service and installation really delivered on their promises!The installation team of Arthur and Adrian was a great one and they really are the type of people you are happy to have in your home. The disruption to the house was super miniimal with literally just a little bit of painting needed afterward. They knew exactly what they were doing and thoroughly hoovered and cleaned up at the end of each day. They even removed the old windows and doors each day to avoid any debris hanging around on site, perfect.A special shout out to engineer Mick who is a complete gentleman and his expertise and vast knowledge was invaluable both before and after the job was finished. He even tweaked the initial design to make sure we got the best outcome and were clear on what we were getting! Everything was efficiently overseen by Sandra and Taylor in the office who kept us up to date on scheduling throughout.I would 100% recommend Gobal and wouldn't use any other company on a future project. They really are the best in the business!

We are very happy with the work Global did on our Kitchen roofs in June 2004. The job was complex and involved a lot of work, even though it was quite small. Marion and his team, who worked on site, got on with the job and caused no disruption. Job well done!

Pat McCann

12:59 07 Jun 24

I purchased a new front door over seven years ago and recently noticed that the colour had badly faded, so I rang seeking a quote for it to be repainted. To my delight I was referred to the service team who informed me it was still under guarantee. Within a couple of weeks, at a mutually convenient time, a painter arrived and within 45 minutes my door looked as good as the day it was first installed. But don't just take my word for it, see for yourself in the photos. Well done Global and your Team.
