Our services



PDH Estimating provides a complete breakdown of all services, materials and labour costs associated with building a residential or small scale commercial project.


Builders & Developers

“Are you tired of pricing projects in your spare time?” Then let us do it for you. We can apply your own supplied rates to your estimates, thus giving the estimate a more accurate end figure, or you can use our rates to compare and keep your sub-contractors in check!

All costs are broken down into individual items and listed into their respective trades, allowing you to easily locate each individual item and cost.

We can also prepare for you, just to frame, lock-up or the fix stages. We even can just estimate the materials or labour if that’s what you want.
Just ask us!


Project Builders

Have your standard house plans costed with the ability to have those costs updated at your request and also have changes made as per your clients request, easy!



Architects & Designers

Get your designs estimated from the initial sketch stage to ensure that your client can afford to build the project, then, at the working drawing stage or the tender stage, we can review the costing to ensure the project is still within that budget, taking away future stress of unhappy clients who cannot afford to continue with the project.


Owner Builders

Owner builders, from the outset, know what the cost of you project will be and don’t be overcharged by trades because you have no idea of the cost, be armed with an entire breakdown of every cost for each trade and take back control of your budget. Compare our estimated costs with your quotes and then feel confident in negotiating a better deal to finalise your project.


Estimating fees


The last thing you need is another expensive service that adds to the thousands of dollars your project has already costed before you even start to build. We have set out a few examples of the types of projects and what our complete service charge would be. Estimating is a rather straight forward process and the size of a project is not to be considered in relation to the service fee, so don’t pay square metre rates for the estimate as it doesn’t take twice as long to estimate an 600m2 house than one of 300m2. It should be based on time, not size or postcode, just because your project is being built in the inner city and may carry a million dollar price tag makes no difference in how we estimate it!

We don’t charge extra to include decks, outdoor entertainment areas, extensive paving and the like. It’s all part of our inclusive service! Just email or post your drawings to us and we will send you a fee proposal to confirm our service fee and our current timing schedule, but generally we like to allow between 7 to 10 business days from the “OK” to proceed.
