"Very prompt I rang them for a quote and that same day they came to my home and had a look at the job, the following day I received my quote and they began the work when I gave the go-ahead Reliable and pleasant people to deal with. Friendly and professional with reasonable prices."


"July 2011, I was need of a builder for renovations to my property. After consulting another 2 builders, I was impressed with Shaun and Tony Spencer’s honesty. I had my own ideas, but they showed me other ways of doing the job, more cost efficient, and aesthetically more pleasing to the eye. They have since been back several times over the years and carried out further work to my residential property and rental property. No job too big or too small, as i had both. Shaun and Tony are not only honest, they are punctual and reliable. I have no problems in leaving them in my house during my absence.

I would highly recommend Gaspen Pty Ltd for any building requirements."


"Hi all,
I recently used Gaspen Pty Ltd to do some renovations for me. The renovations were quite extensive and out of the ordinary.I found Shaun, the main builder, to be hardworking, honest willing to be flexible with my changing plans and he delivered a very high standard of workmanship.As usual there were extras, these extras were discussed with me prior to the changes and a reasonable price was discussed and agreed to.
Gaspen Pty Ltd is a honest, reliable family business and I will use them again for my next building project."


"Hi Tony and Sean,
We have used Gaspen on 2 occasions now and have been thoroughly impressed with the quality of their work and the timely manner in which that work has been completed. We have no hesitation in recommending them to anyone, having recommended them to friends already that were also very impressed with their work."

Gaspen Pty Ltd is a third generation building company with over fifty years of experience. We are Tony (2nd generation, in the building game since 1977) and Shaun (3rd generation, since 1986). George, Tony’s father and Shaun’s grandfather is now in his nineties having a well- deserved break.

We moved to North Queensland in 1995 where we have enjoyed calling it home, loving the weather, the fishing and the people. We are proud of the fact that we buy our materials and tools from locally owned suppliers. We also have a strong connection with our local sub-contractors whom we trust and work closely with.

Being carpenters we love to work with timber and really enjoy a challenge. Queenslanders are definitely our specialty, however we are not limited to this building style. When it comes to building, we do it all! From maintaining existing structures, to enhancing a current space, to creating something totally new.

Our aim is to make you happy. We want to give you an honest, no BS building experience. We are not salesmen, we are simply builders. We have the experience in the industry to help with your design ideas and the skills to build it to your expectations. Most importantly, we don’t blow our own bags and claim to be the best builder in town, we let our workmanship speak for itself.
