Testimonials

"We are so pleased to find a company that was conscientious, responded quickly, and was able to help us from the design stage, project completion, through to ongoing maintenance. It is not unusual for them to get a kitchen back up and running the same day, which is crucial when working in care homes and commercial kitchens, for example.’
Kitchen Catering Company
‘It was so great to find a fellow family run business who were very knowledgeable and able to effortlessly help us resolve our extraction issues.’
Restaurant, London
‘Since employing Advent Maintenance we have saved enough on repairs and breakdowns to install new systems. They carry out planned preventive and reactive maintenance timely and efficiently and have a team of experienced engineers.’
Materials supplier
“From initial concept to final commissioning, the team demonstrated outstanding technical knowledge and attention to detail. The bespoke ventilation system they designed and manufactured fits our building perfectly and performs exactly as promised. Installation was smooth, well managed and on programme.”
Estates Manager, Commercial Office Development
“We have used Advent for multiple projects covering HVAC, ductwork manufacture, and plant installation. Every project has been delivered professionally, safely and to a high standard. Their in-house manufacturing capability gives them a real edge.”
Mechanical Consultant
“The quality of installation and attention to detail was excellent. The site team were polite, organised and proactive in solving problems. Commissioning and handover were thorough, and ongoing maintenance support has been first class.”
Facilities Manager, Healthcare
“Their ventilation and plant design was clearly developed around the building, not forced into it. Performance, access and future maintenance were all considered. This level of thinking is rare in the industry.”
Architect
