New Door, great job

Replaced my front door in a very efficient manner. The team arrived on time and took away all the debris. They were meticulous in ensuring that the door furniture was in the positions that I wanted. They were courteous and very professional.

New gutters and soffits

I had new gutters and soffits fitted in the height of the heatwave in July. The fitters were Valentin and Darryl. Two of the nicest people ever. Very capable, efficient, tidy and pleasant. The work was done to a very high standard and I would recommend Global to anyone.

Checked out window handles, arranged to have them replaced, friendly worker

Yes surely! Came at arranged time, efficient and amiable young man who followed up on the task to be undertaken when the part was not available at Global. Adjusted window ‘settings’ and oiled window joints. Did the work under a guarantee for our door installation though the windows were well out of guarantee! Many thanks. Caoimhe
