Who we are

About Shamrock Joinery

With locations in Sydney, Newcastle and the Central Coast, we offer our services to a wide range of residential and commercial buildings.

Working with Shamrock Joinery’s professional team, you can order custom made designs measured to your space, or bespoke windows and doors specially made for you.

We work with both traditional and modern architectural styles. Because of our experience working with old and new buildings, we even create doors and windows for heritage properties. For buildings of all types, styles, and ages, we at Shamrock Joinery are ready to work with you for an incredible result.

Materials We Use

All our products are crafted using sustainably sourced timbers from around Australia.

Choose between:
  • Jarrah
  • Blackbutt
  • Grey Ironbark
  • Spotted Gum
  • Merbau
  • New Guinea Rosewood
  • Western Red Cedar
  • Accoya
  • Manilkara (Pacific Jarrah)
  • European Oak

The WRC timber is our choice for most projects, due to its naturally superior characteristics. It’s naturally resistant to moisture, decay and insects, making it an ideal choice for use both internally and externally. WRC is also highly durable, along with its smooth, refined appearance.

All timber products are supplied with a clear water repellent treatment, or with a white primer undercoat, depending on the eventual plans of the builder or owner. Based on the location and climate where the product will reside, we can make a recommendation to help you choose an appropriate finishing treatment.

Working with
Shamrock Joinery

We strive to serve every customer with respect and dignity. Our team works with you to deliver a product of superior quality that perfectly suits your needs. Bring your expectations to Shamrock Joinery, and we will work with you to create the ideal design.

Behind our success as a company is our dedicated team of hard-working people. Our team is as passionate about the perfect result as you are, with our goals revolving around providing the best service and products possible.


As part of our commitment to working in a way that doesn’t damage the environment, we source our timber from publicly managed forests. Our choice wood, the Western red cedar timber, is always harvested responsibly and sustainably.

Every year, less than 1% of the cedar grown in British Columbia (BC) are harvested. These are trees specifically planted for harvesting and use in the timber industry. In the BC publicly managed forests, three trees are planted for every one that is harvested.
According to lifecycle assessments completed throughout the years, wood has consistently been named as the most environmentally friendly construction material. Wood is a renewable resource that can be recycled easily and used in versatile applications. As long as the timber is sourced from a well-managed forest, it’s the best choice for the environment.

– Renn

As residential architects we are often designing bespoke solutions for our projects and windows and doors are a very important part of the spaces we create. We have worked with Shamrock Joinery over a number of years and several projects and we have developed a close working relationship. They are reliable, efficient and make positive contributions to the process of creating the window and door solutions that work with our architecture. They consistently produce a high-quality product and I have no hesitation recommending them for timber windows and doors. As an architect with over 25 years’ experience I see the value in fostering relationships with good companies and Shamrock is certainly one of these.

I thought I would drop you a line and say how happy we are with the renovation and especially the front door you made for us last year. The front door to the house is what makes the first impression to the property and the door that you made certainly makes a great first impression. Thanks again for your brilliant workmanship and superb service and we have been telling anyone who asks where they can get well-priced quality joinery. Thanks again

I have just taken delivery of my new doors and windows from Shamrock Joinery and I wanted to send you a quick email to say thank you.

We live in a very old small house and since moving in 3 years ago we have needed to do quite a bit of work on the property. In all this time I have dealt with various suppliers/trades people and I can honestly say that Shamrock Joinery has been magnificent.

Brendon has been my main contact and has been such a pleasure to work with. He has answered all my many questions and his attention to detail and customer service skills have been exceptional. The fact that he came back to the house to double check all measurements at a time that was convenient for me and also the carpenter was outstanding.

I also need to mention Jessie who has also been so wonderful to work with. She has such a warm, pleasant manner on the telephone and has been really helpful.

Last but not least, Patrick the driver today actually blew me away. He called to advise that he would be arriving at approximately 10:45, and it was literally on the dot that he arrived. Normally you are given a ridiculous delivery time slot and never a time that a driver actually keeps to, so a big thank you to Patrick as well. Thank you so much, you have a great team.

I have been requested to forward a reference to recommend Shamrock Joinery for the Scots College Project. Shamrock’s quality and craftsmanship speaks for itself, for example all the windows and doors of the Annexe building; the restoration of Aspinall House; the restoration of the main school corridor and the Principals office; the restoration of Fairfax House; and the most recent restoration of Kirkland House has been carried out by Shamrock Joinery. I can only speak highly of their company and their approach to their craftsmanship. The College has the highest admiration of their workmanship, particularly when you come to the restoration of the old buildings. They have been able to tool up to be able to replicate within a millimetre to match existing.

One of the most particular and intricate jobs that they supplied and installed was the new Atrium at Aspinall House which was constructed to replicate the original building which was demolished in the 60s and was subsequently replaced two years ago.

Shamrock is my preferred company when I do work outside of Scots because I admire their craftsmanship.

As you can see from my high praise of this company, I would highly recommend them and the College is completely satisfied with all of the work that they have carried out from them over the years.

My experience with Shamrock Joinery & Associates has been exceptional.

They provided a top-quality product, with the utmost standard of joinery work I would be happy to comment. They were able to meet my specifications with no reservations and were always courteous in their dealing with the project.

The staff at Shamrock are professional, experienced and reliable and the customer is treated with respect. In addition, my product was delivered on-time and with no hassle, with great communication provided. I would be happy to consider Shamrock Joinery & Associates for future projects and would recommend the quality of their work.

Please do not hesitate to contact me should you wish to discuss.

Thank you

My dealings with Shamrock Joinery to this point have been a pleasurable experience.
I have contracted Shamrock Joinery for the fabrication and delivery of timber and glass doors and windows on two high-end projects at Whale Beach and Palm Beach.

Both projects have involved custom joinery that was architecturally challenging. At every instance I have found their staff to be punctual, reliable and knowledgeable.

I have found them willing and able to assist me in getting the best product onsite to meet my design, performance and durability requirements.

All deliveries have arrived in good order and on the agreed date. I have no hesitation recommending Shamrock Joinery.

Please feel free to contact me to discuss this reference on 0422 308 237.

Dear Richard & Shamrock Team,

I just wanted to take time out to say thanks to the team at Shamrock Joinery, the new French doors you provided are fantastic. The panels match up perfectly to the heights of the wall panels, really impressing our very detail-oriented client, and wanted to let you know that your attention to these finer details and the fact that nothing was too much trouble (from order through to delivery) was really appreciated.

We look forward to working with you in the future.

Yours sincerely,

– Linda Ryan – Ryan Constructions &
Project Management Pty Ltd

I have recently had work done at my property by your company and would just like to say how happy I am with the outcome. The quality of material and workmanship is second to none. The workers were on time everyday and very pleasant to have around. The house was left very clean at the end of each day. From the start deciding which doors to use through to completing the job was made so easy by your company. Also it was a pleasure dealing with Richard Dowdall. I would have no hesitation in recommending Shamrock Joinery to my friends. Thank you.
