Martin Kay

“We have employed Trinity Harper to clean our offices and workshops for well over 10 years and we have always found Andries and his team to be very accommodating and professional.  As our company has grown Trinity Harper has been flexible to our needs and we would be happy to recommend them to other businesses.”

“We have been using Trinity Harper Cleaning for a while now and have been very pleased with their service. They are always very helpful in arranging last minute cleans for us and the cleaning is always completed to an excellent standard.

We would definitely recommend their services to anyone.”

“I have worked with Andries and Trinity Harper for the last four years, no matter whether the project has been large or small we have received nothing but a first class professional service from him and his team, sometimes at very short notice and usually with difficult constraints. His operatives amaze with their work ethic and I cannot recommend highly enough.”
