Trade-Grade Fitting Services

Fitted aluminium window sills must do more than look clean—they must provide a permanent weathering barrier. Improper installation leads to water ingress, thermal bridging, and structural render cracking.

Our dedicated team of fitting technicians specializes in installing deep-reveal window sills, parapet wall cappings, and custom architectural trims. We work closely with main contractors, SEAI insulation installers, and glazing companies to align with project schedules.

By coordinating measuring, manufacturing, and fitting under a single contract, we remove the risk of finger-pointing between different trades. If we measure it and fit it, we guarantee a watertight seal.

// Watertight Seal Guarantee

Our technicians use only B2B-certified low-modulus silicones, EPDM rubber expansion gaskets, and thermal break decouplers to isolate the aluminium from the masonry.

Our Fitting Standards

  • 01

    Sub-Cill Preparation

    We clean and level the masonry sub-cill, applying high-performance damp-proof membranes (DPM) before positioning the aluminium.

  • 02

    Thermal Expansion Gaps

    We establish precise movement gaps between long linear runs, utilizing internal joiner plates to guide thermal movement.

  • 03

    Reveal Stop-End Sealing

    We seal and mechanically secure high stop-ends to prevent rainwater from spilling sideways into EPS insulation or render reveals.

  • 04

    Final Quality Sign-off

    Every installation undergoes a quality check, ensuring all drip edges align, expansion joints are sealed, and finishes are flawless.

// Fitting FAQs

Installation Details

Do you fit sills on deep External Wall Insulation (EWI)?

Yes. In fact, deep-reveal retrofits are our specialty. We supply and fit extra-deep sills (350mm+) with specialized support brackets and thermal breaks, ensuring render reveals remain crack-free and watertight.

Can your team fit custom capping systems?

Yes. Our installation technicians regularly fit parapet wall cappings using both secret-fix bracket systems and direct-fix configurations, including fully welded corner units and expansion splice joints.

What is your coverage area for fitting?

Our fitting service is available nationwide across Ireland, serving developers and trade contractors in Leinster, Munster, Connacht, and Ulster.
