OUR PROFESSIONAL, CERTIFIED TEAM
If you’re looking for a build partner you can truly rely on, Sureline Building Group is here for you. Our fully licensed and certified team delivers prompt, professional service backed by genuine care and decades of experience.
Whether you’re upgrading your existing space or extending your home, you can trust our experts to manage every detail with precision and respect for your time and property. We take pride in offering a stress-free, seamless renovation experience — one that reflects our family values and commitment to craftsmanship.
The cost depends on size, materials, and design complexity.
As a guide, most decks start from $15,000–$25,000, while covered outdoor areas or pergolas range from $25,000–$45,000+ for premium finishes.
We provide clear, itemised quotes so you know exactly what’s included — with no surprises along the way.
In many cases, decks and pergolas can be built under Complying Development (CDC) approval — especially if they meet height, boundary, and size conditions.
However, every property is unique. We’ll assess your site, confirm requirements with Shoalhaven City Council, and handle all approvals if needed.
We use only coastal-grade materials built to withstand Shoalhaven’s salty air and weather.
That includes:
Treated pine or hardwood framing (H3/H4 rated)
Hardwood, ModWood and all composite decking options
Stainless or galvanised fixings
Colorbond or polycarbonate roofing for pergolas
We’ll help you select the right materials to balance aesthetics, performance, and budg
Most projects take between 1 and 3 weeks once work begins, depending on size and complexity.
We provide a detailed schedule before starting and maintain clear communication so you know what’s happening each day.
Absolutely. We design every structure to blend seamlessly with your home’s style, proportions, and materials.
Whether it’s a modern extension off your living space or a coastal pergola with screening, we’ll make sure it looks like it was always meant to be there.
Yes — especially for decks adjoining living spaces or built over lower areas.
We provide all required waterproofing, proper falls, and concealed drainage systems to prevent leaks and ensure long-term durability.
We’re a local, family-run builder with deep experience in coastal conditions.
Every Sureline project is delivered by qualified trades with clear communication, reliable scheduling, and premium workmanship — from footings to final oil coat.
