About Tradewind Building Maintenance

Tradewind Building Maintenance has been serving Wollongong since 2007, bringing almost 20 years of hands-on carpentry, renovation, handyman and building maintenance experience to homes and small businesses across the Illawarra. Behind the name is one person, John Douglas, a licensed tradesman who takes on every job personally, from the first phone call through to the final walk through. When you work with Tradewind Building Maintenance, you work with John.

Meet John Douglas

John Douglas is the tradesman behind Tradewind Building Maintenance, and has been since registering the business as a sole trader in 2007. Over almost 20 years across the Illawarra, John has built a reputation the old fashioned way, through word of mouth, repeat clients, and homeowners who recommend him to their neighbours. That reputation matters more to him than any marketing line. Customers who leave reviews across Wollongong mention John by name, not a company, because that is exactly who turns up to do the work.


John holds NSW carpentry contractor licence 203410C and operates under ABN 29 415 606 559. He carries public liability insurance and workers compensation cover on every job, so homeowners across the Illawarra are properly protected whether the work is a single repair or a full renovation.

How Tradewind Building Maintenance Began

Tradewind Building Maintenance was registered in 2007 as a one person carpentry and building maintenance business, and it has stayed that way by choice. John set out to offer Wollongong homeowners something a larger outfit often cannot, a single licensed tradesman who is personally accountable for a job from start to finish, rather than a rotating roster of subcontractors. Almost 20 years later, that is still the model. Tradewind Building Maintenance has grown through the trust of local homeowners rather than through expansion, and John still measures the business by the same standard he started with, quality craftsmanship and a job done properly the first time.

What We Do

Tradewind Building Maintenance covers the full range of carpentry and building maintenance a Wollongong home is likely to need, all delivered personally by John:


  • Carpentry, including structural framing, decks, pergolas, doors, architraves and custom joinery
  • Renovations and alterations, from single room upgrades, bathrooms, to larger extensions
  • General building maintenance and handyman work, for the small jobs that keep a property in good order
  • Custom built and tailored joinery, shelving and cabinetry, built to suit your space rather than off the shelf
  • Repairs, including timber rot, storm damage and general wear from the Illawarra's coastal climate

Every job, large or small, gets the same attention to detail and the same tradesman turning up to do the work.

How We Work

Tradewind Building Maintenance runs on a simple, consistent process, from your first conversation to the final finishing touches:


  • Assessment: John discusses your job, visits the site, and looks closely at what is actually needed before recommending anything
  • Design and planning: the scope, materials and timeline are agreed upfront, with a clear written quote so there are no surprises
  • Construction: work is carried out with care and respect for your property, treating it as if it were our own
  • Finishing touches: a final walkthrough and tidy handover, with John remaining contactable afterwards if anything needs revisiting

This same process applies whether the job is a full renovation or a single repair, because the standard of care does not change with the size of the job.
