B2B Services // On-Site Survey
Eliminate ordering errors and idle subcontractor labor. Our on-site measuring service guarantees every custom aluminium sill fits first time, every time.
Digital Certainty
Aluminium window sills are completely unforgiving. Unlike timber or lead, they cannot be trimmed, stretched, or reshaped on site once they have been CNC folded and powder-coated. A 10mm error is the difference between a successful handover and a costly scrap scrap.
EWI (External Wall Insulation) and ICF (Insulated Concrete Formwork) projects introduce additional reveal thickness variations. Measuring these openings manually leads to transcription issues, wrong clearance calculations, and disputes.
By shifting to our guided professional measuring service, you hand off the liability of sizing to us. Our technical surveyors verify the masonry reveals, thermal breaks, and window frame clearances to ensure absolute precision.
When we measure it, we own the fit. If there is any sizing mismatch during installation, we fast-track a replacement from our Dublin workshop at zero cost to your project.
The Process
We inspect structural openings, checking reveals for squareness, insulation cavity dimensions, and potential cold bridges.
Using digital survey tools, we capture the exact millimetre data directly from the window frames and insulation margins.
Our technicians calculate proper margins for thermal expansion, upstands, drip edge projections, and stop-end clearances.
Survey data feeds directly into our Dublin workshop, generating the vectors needed for CNC folding machines with no manual transcription.
// Irish Coverage
From commercial developments in Dublin to ICF projects in Cork, Galway, Limerick, and Waterford, our surveying team travels to your site, keeping your project moving.
// Service FAQs
We recommend scheduling the site survey once window frames are fully fitted and the external insulation (EWI) or ICF boarding margins are established. This ensures we capture the exact final reveal boundaries.
Yes. You can download the Cills app or visit Cills.ie to use our guided 3D configurator, which walks you through entering your own reveal measurements step-by-step. However, for large commercial contracts or complex bay window configurations, our on-site survey service is recommended to guarantee the fit.
Our technical surveyors use high-precision 3D digital laser scanners, digital protractors for angled bay windows, and custom calibration gauges that replicate folding boundaries to verify window track clearance.
