Testimonials
What Sydney Homeowners Say About UrbanArch
"I have just had my deck replaced with Trex. Tony replied immediately, came to measure and quote within days, and returned a few days later to discuss. The transformation is amazing, but I cannot talk highly enough of the service I received. The boys on site were reliable, capable, polite and extra helpful with everything I asked."
"I cannot speak any higher on the professionalism, pride, and workmanship of the Urban Arch team. We were kept updated and the project finished on time. The deck looks fantastic. If there was a score out of 10 with 10 being the highest, I would rate them 12."
"From the very first consultation to the project's completion, Tony and his team were nothing short of professional, friendly, and genuinely committed to going above and beyond. The quality of the work is exceptional, and we absolutely love how our new deck and entertainment area turned out."
"I recently had a two-storey deck built and could not be more thrilled with the results. Tony and Dean demonstrated exceptional professionalism, clear communication, and attention to detail. The project was finished on time and exceeded my and my wife's expectations."
"Tony and his team redid our deck area which required strict compliance with council rules. They were very professional, completed the task in good time, and the transformation was outstanding. The team kept us informed every step of the way."
"Thanks so much Tony. Can I just take this opportunity to thank you for the way you and your team approach the work you do. It's the little things that show the value we are receiving."

Our Process
What Happens When You Enquire With UrbanArch
A lot of people put off calling a builder because they are not sure what they are walking into. Here is exactly what to expect — no hard sell, no pressure, no judgement.
1
A Quick Call (15 Minutes)
We ask about your space, your ideas, your rough timeline, and whether you have a budget in mind. No pressure, no judgement. We want to understand whether we are a good fit for each other.
2
Free Consultation
We share information so you can make informed decisions — decking brands, substructure options, special features, finishes, handrails, lighting, privacy screens. We provide samples and answer every question honestly.
3
Indicative Pricing
Once we understand your project, we provide an honest indicative price range — always very close to the final figure.
4
In-Home or Site Visit
We visit your property, go over all the details in person, and confirm the pricing. Then we provide a detailed fixed-price quote covering everything discussed.

FAQs
Common Questions About Deck Building in Sydney
Do you use subcontractors?
No. The team building your deck are our own skilled carpenters — they work only for UrbanArch. No subcontracted labour, no handoffs.
What warranty do you offer?
Every UrbanArch deck comes with a 10-year installation warranty covering the substructure to the surface. Composite boards also carry manufacturer warranties — which we protect by following installation guidelines exactly.
How long does a deck build take?
This depends on the size and complexity of your project. We will give you a clear schedule before work begins and keep you updated throughout. We commit to a timeline and honour it.
Do you handle council approvals?
Yes. We can manage council applications and certifier approvals as part of your project. We will advise you on what is required for your specific site and location.
What is the difference between composite and timber decking?
Composite decking (Trex, Millboard, TimberTech) offers the look of timber with virtually no maintenance — no oiling, no sanding, no staining. Timber decking offers natural warmth and character, and with the right species and care, is extremely durable. We will help you choose the right material for your lifestyle, budget, and home during the free consultation.
Do you service areas outside Sydney?
Yes. We service Sydney-wide, plus Wollongong and the Southern Highlands.
Is there any pressure to sign or commit on the spot?
None. We will never ask you to sign today for a discount. Take your time, compare if you want to, and come back to us when you are ready.
