Site Coordination and Division of Responsibilities
A productive labour-only or installation-only subcontract depends on a clearly agreed division of site responsibilities between the main contractor and our glazing company installation team:
| Operational Area | Main Contractor Responsibility | Window Fitters Ltd Installers Team Responsibility |
|---|---|---|
| Materials and Delivery | Procurement, site delivery, unloading, verification against supplier packing lists, and vertical distribution to fitting floors. | Pre-installation condition check, defect logging, hardware inventory check, and protective film management. |

Pre-Installation Defect Inspection & Glass Breakage Protocols
Operating as an installation-only glazing company where materials are supplied directly by the client or trade fabricator, protecting the manufacturer warranty requires strict material intake controls. Prior to lifting any frame or glass unit, our lead glazier conducts a joint condition inspection with your site agent:
Checking glass panes for transit scratches, edge chips, inclusions, or hermetic seal failures before installation into openings. Any defect is photographed and logged immediately on the site delivery manifest.
Checking powder-coated aluminium or foiled uPVC frames for transit dents, mitre joint gaps, or hardware discrepancies prior to anchoring into masonry reveals.
Ensuring double and triple glazed units are correctly packed diagonally using calibrated bridge packers to maintain sash squareness and prevent dropped sashes over time.
Installing structural frame anchors to specified torque tolerances under BS 8213-4:2016 without distorting outer frame profiles or bridging thermal breaks.
JCT Labour-Only Subcontracting, Crane Lifting and Site Logistics
For commercial main contractors and residential developers procuring their own glazing packages, Window Fitters Ltd provides reliable integration under standard UK subcontract conditions. We operate under JCT Design and Build (DBSub) or Minor Works (MWSub) labour-only subcontract orders, ensuring full statutory compliance under the Housing Grants, Construction and Regeneration Act 1996 with agreed monthly payment applications, timely payment notices, and standard CIS administration.
When installing heavy glass units, oversized patio sliders, or structural curtain walling, our teams coordinate contract lifts in accordance with LOLER 1998 and BS 7121 standards. We deploy Maeda MC285 and Unic URW-095 compact spider crawler cranes, paired with Woods Powr-Grip MRTA611LDC dual-circuit vacuum lifters (up to 600 kg capacity). Qualified CPCS Appointed Persons prepare lift plans, while certified crane supervisors and slinger / signallers manage lifting zones, stillage offloading, and floor-level distribution.
