Mayo is a vast Atlantic county from the heritage town of Westport to Castlebar and Ballina. Much of it is exposed western coast and bog, with a high share of one-off rural homes and holiday properties.
Local demand: Coastal exposure makes roofing, rendering and reliable heating essential, while Westport's tourism drives guesthouse and holiday-let upgrades.

What Mayo homeowners hire builders for
General builders manage and carry out larger construction projects — extensions, full renovations, attic and garage conversions, and structural alterations. A good main contractor coordinates all the other trades (groundwork, blockwork, roofing, electrics, plumbing, plastering) and keeps the job on programme and on budget. For anything structural, you'll also need engineer and, often, planning input.
- Single and two-storey extensions
- Full house renovations and refurbishments
- Attic and garage conversions
- Structural alterations (removing walls, steels)
- New builds and self-build management
- Knock-throughs and open-plan conversions
- Project-managing multi-trade jobs
