How We Work
Every exterior job is different, so we scope each one carefully and coordinate delivery through our trusted partner, keeping you with a single point of contact throughout.
01. Enquiry
You tell us about the building, the surfaces and the result you need. We talk through access, timing and any site constraints so we understand the job before we go any further.
02. We Scope & Coordinate With Our Partner
We scope the work, arrange a site assessment where needed and brief our vetted specialist partner. We confirm method, access and scheduling, and gather the insurance and RAMS documentation so everything is in place before work starts.
03. Partner Delivers, We Oversee
Our trusted partner carries out the specialist cleaning to the agreed scope and method, while Optimum manages the schedule and oversees delivery on your behalf. You continue to deal with us, not a separate contractor.
04. Sign-Off
We check the finished work against the agreed scope and confirm you are happy before the job is closed. Completion records and any documentation are made available on request.
Who is it for?
We coordinate external cleaning for organisations that want a clean, well-kept exterior without sourcing and managing a specialist contractor themselves.
