When Should You Replace Your Skylight?
Not every skylight issue can be repaired — sometimes a full replacement is the most cost-effective and long-lasting solution. Our network of specialists can help you determine whether repair or replacement is the right choice for your situation.
- Skylight is more than 20–25 years old
- Repeated leaks despite previous repairs
- Badly yellowed, cracked, or delaminated acrylic dome
- Structurally damaged frame that cannot be repaired
- You want to upgrade to a larger or energy-efficient model
- Hail or storm damage requiring full replacement
Types of Skylights We Replace
- Fixed skylights — standard non-opening models, available in flat and domed styles
- Ventilating / opening skylights — open manually or electronically for airflow
- Tubular skylights — compact light tunnels ideal for bathrooms, hallways and small rooms
- Custom or heritage skylights — bespoke designs for older homes and commercial buildings
- Commercial polycarbonate roof panels — large-format skylight systems for warehouses and retail
The Replacement Process
A typical skylight replacement involves:
- Inspection & measure-up — the repairer assesses the existing opening and recommends suitable replacement options.
- Product selection — you choose from available brands and styles. Popular brands include Velux, Fakro, Solatube and ODL.
- Removal of old skylight — the existing unit is carefully removed and the opening prepared.
- Installation — the new skylight is fitted, flashed, and sealed to ensure a weathertight finish.
- Internal finishing — plasterboard, paint touch-ups, and internal trim are addressed.
