Season Master, Replacement Windows and Doors in Mayo

Season Master is listed on the SEAI register for external windows and external doors, as of the register download on 7 August 2026. Registered with SEAI for windows and doors only. The register changes, so check the current entry with SEAI directly.

Season Master is based in Mayo and works across Castlebar, Ballina, Westport, Claremorris and Belmullet. The SEAI register also lists 4 other counties in their service area, so it is worth asking how far they travel for a job your size.

Most of the housing here is dashed render bungalows built to take weather, farmhouses, and fully exposed coastal properties. The local condition that shapes the job is sustained Atlantic wind and horizontal rain, among the harshest conditions in the country, which is why wind-driven rain finds any weakness in the perimeter seal, so fitting quality outranks glazing spec here.

Use the enquiry form on this page and it goes straight to them, or ring them on 094 903 1153. Ask for a measured survey before any price, get the quote in writing, and confirm who makes good the plaster inside and the render outside once the old frames come out.

Ask for a measured survey before any price, and get the quote in writing afterwards. Confirm three things in particular: whether removing and disposing of the old frames is included, who makes good the plaster inside and the render outside, and what the lead time is. Made to measure frames run six to twelve weeks, so the survey date is not the start date.

Castlebar is in Mayo, where Season Master is registered, so yes. They work across Castlebar, Ballina, Westport and out to Belmullet. Whether they will travel to a specific townland is worth asking directly, particularly for a smaller job.
