Why our customers choose us

Not all big changes are big builds

You may not need a whole new building, you may just need help with some small adjustments to make your current space work better for you. McMullen Builders can help with that as well. From internal alterations and additions, as well as full interior fit-outs for commercial sites and schools, we can find something that fits your specifications.

Making it whole again

Our attention to detail and knowing how important it is to get going again, helps us under-take insurance works and fire damage up-grades. Getting you back in the premises as soon as possible is hopefully one less head-ache during what can be a testing time.

A fully-qualified team

In our continuation to offer all services and skills to help make the build process easier, we also specialise in the secondary parts of demolition and construction. With fully-qualified experts to handle full building asbestos removal as an example, McMullen Builders have the systems in place to handle all situations.

The know-how to make it happen

With our investments into the latest in building technologies and in the constant training of our team, we are able to complete most projects twice as fast as others in the industry.

The continued partnership

An extra element we pride ourselves on is our 24 hour on-call service to help get you the right person for the right job. The build may have finished, but we continue to provide support if an emergency happens.
