Serving the Central Coast and surrounds
Renovations & Extensions on the Central Coast

JWT Construction & Maintenance is a licensed builder based in Lake Munmorah, right in the heart of the Central Coast. Whether you're renovating a bathroom in Gosford, adding a deck in Terrigal or extending your home in Wyong, we're local and we're ready to help.
The Central Coast is home territory for JWT Construction & Maintenance. Our base in Lake Munmorah puts us within easy reach of the region's coastal suburbs, lifestyle properties and established family homes — and we've built and renovated across the area for over 13 years. Led by Jesse Theil, a fifth-generation builder who learned the trade through his family's building business, we bring genuine craft and real attention to detail to every Central Coast project we take on.
Homeowners across the Central Coast are increasingly investing in their properties — whether that's a full bathroom renovation to modernise an older home, a timber deck to make the most of the coastal lifestyle, or a ground-floor extension to add space for a growing family. We handle every stage of these projects ourselves, from design and council requirements through to the finished result, so you're not juggling multiple trades.
We're also available for after-hours maintenance callouts, insurance make-safe work and strata repairs across the Central Coast. No job is too straightforward — if your property needs attention, we're a call away. All work is backed by our NSW builder's licence, Home Building Compensation cover and public liability insurance, giving Central Coast homeowners genuine peace of mind.
