Real Feedback from Our Customers
Expert Windows Ltd. supplies and installs windows and doors in Dún Laoghaire and the surrounding areas of Monkstown, Sandycove, Glenageary, Sallynoggin, Killiney and Dalkey. Our team has fitted windows and doors in South County Dublin for over two decades, from Victorian terraces on the seafront to apartment blocks and offices in the town centre.
The housing around Dún Laoghaire asks more of a window company than most areas. Period homes need sash windows and doors that keep the proportions of the original, and some are protected structures where the specification has to be agreed in advance. Apartments in Monkstown and Glenageary often have management company rules on colour and style. Homes on the coast need frames and glass that stand up to salt air and wind. We work through all of that at survey stage so the quotation is right first time.
Whether it is a full-house replacement, a front door with a glazed surround, or new double glazing in a second-floor apartment, we survey, manufacture to measure and install with our own team.
Our Range of Windows in Dún Laoghaire
Sash, casement, tilt and turn and bay windows in uPVC, aluminium and Aluclad, with double, triple and acoustic glazing. Sliding sash windows in uPVC or timber-look finishes are our most requested window in Dún Laoghaire’s period streets.
For apartments we replace windows to match the existing block, supply the specification the management company needs, and work around access to upper floors.
Slim aluminium windows with low U-values suit the contemporary homes and extensions around Sandycove and Killiney, and the offices and clinics in Dún Laoghaire town. Marine-grade finishes are available for exposed coastal positions.
A-rated uPVC casement and sash windows replace single glazing at the best price. Available in white, cream, grey, black and woodgrain finishes, including brown for homes that want to keep a timber look.
Aluclad sash and casement windows are the right choice for Dún Laoghaire’s larger period homes: timber inside, aluminium outside, excellent insulation and no maintenance in the sea air.
Our Range of Doors in Dún Laoghaire
Composite, timber-look, aluminium and uPVC front doors, doors with side panels and glazed surrounds, French and sliding doors to patios and gardens, and apartment entrance doors. All made to measure with multi-point locking.
Palladio and Apeer composite doors in Georgian, Victorian and contemporary styles, with side panels and fanlights to match period entrances. Solid, secure and never need repainting.
Contemporary aluminium entrance doors with U-values under 1.0, and aluminium sliding and bifold doors for garden openings and sea views.
