As a registered Velux installer, our team supplies and fits the full range of Velux roof windows across Knocklyon — for new installations, loft conversions and like-for-like replacements. We also carry out repairs to existing Velux units where the flashing kit, frame seal or glazing has failed, which is among the most common sources of persistent roof leaks in Knocklyon properties with Velux windows installed 15 or more years ago. Installation starts from €800 per window, supply and fit. Free survey and same-day written quote available.

Knocklyon is a well-established south-west Dublin suburb built predominantly in the 1980s, with a close-knit community feel and a range of residential estates on elevated ground between Rathfarnham and the M50. Properties in Knocklyon are predominantly 1980s semi-detached and detached estate houses, some 1990s townhouse developments, and a small number of bungalows on the higher roads. Common roof issues we address here include concrete tile deterioration and ridge tile repointing on 1980s stock, felt underlay deterioration on properties now exceeding 40 years, flat roofs failing on garage and extension roofs, and fascia and soffit replacement, making professional roofing maintenance essential for Knocklyon properties. Our roofers understand the construction methods and typical materials used in Knocklyon — every inspection is free and every job begins with a written quote.
