Dumac Engineering
Two caravan travellers called after hours and had their power fixed by the following morning.
That said, based on those 4 reviews, the standout pattern is rapid next-day response for caravan electrical problems, with two separate customers independently noting that Peter's team showed up the morning after an evening call and fixed the issue fast. Pricing drew a favourable mention in one of those jobs too. It's worth knowing that one review raises concerns about quality of work on a residential new build — specifically lights installed incorrectly during a construction project — though with only four reviews total, it's impossible to say whether that reflects a one-off or something more. Before booking for new build or detailed installation work, it's worth asking Peter directly about the scope of the job and confirming his approach to sign-off and checking finished work against plans.

About Dumac Engineering
Peter runs Dumac as a family-owned electrical and air conditioning business out of Gracemere, and the pattern in reviews points clearly toward a niche: caravan and mobile home electrical work. Two separate customers mention calling late or after hours with caravan power problems — a 240V fault and a general caravan issue — and both report Peter's team arriving the following morning and resolving the job within an hour. That kind of fast-turnaround, next-morning response for mobile travellers is a genuinely specific capability, and it matters in a regional centre like Gracemere where caravan travellers passing through can't afford to wait days for a booking. Beyond caravans, Dumac holds GST registration and operates as a company, which means they can take on residential and contractor-side new build electrical work — and reviews confirm they've worked as the electrical subcontractor on residential builds through NT & CA Smith Building Contractors. The business spans both the licensed electrical and air conditioning trade categories, so split-system installs and related electrical connections are within scope, though reviews don't speak directly to that work. If you're a traveller with a caravan power emergency or a local homeowner needing a licensed electrician for a repair or safety switch job, Dumac's quick-response model appears to be the clearest strength on offer.
Best for: caravan travellers needing fast next-day electrical fault repairs near Rockhampton, and local homeowners needing safety switch replacements or general residential electrical callouts.

Does Dumac Engineering do after-hours or emergency callouts?+
Based on two customer reviews, Dumac has responded to evening calls and arrived the following morning — one customer called late one evening and Peter's team was there early the next day. Both jobs involved caravan electrical faults, so this responsiveness appears most proven in that context. If you have an emergency outside caravan work, it's worth calling directly to confirm whether after-hours response applies to your job type. Either way, fast turnaround appears to be a genuine part of how they operate.
What areas does Dumac Engineering service from Gracemere?+
Dumac is based in Gracemere, QLD, which sits just outside Rockhampton. Reviews don't mention specific suburbs or travel radius, so it's unclear how far they'll travel for a job. Given they've responded quickly to caravan travellers in the area, they likely service the broader Rockhampton region. Confirm your address with them directly when you call, especially if you're outside the immediate Gracemere area.
Is Dumac Engineering experienced with caravan electrical work?+
This appears to be a genuine strength based on the reviews available. Two separate customers mention calling with caravan power problems — one involving a faulty safety switch on a 240V setup — and both reported the issue was diagnosed and resolved in a single visit the morning after they called. Pricing was described as reasonable in one of those jobs. If you're travelling through the Rockhampton area with a caravan electrical fault, this looks like a practical option to call.
Does Dumac do new residential builds or just repairs?+
Reviews confirm Dumac has worked as the electrical subcontractor on at least one residential new build through NT & CA Smith Building Contractors. However, one review from that project raised concerns about lights being installed incorrectly and not matching the electrical plan. With only 4 reviews total, it's difficult to draw a firm conclusion about their new build track record. If you're considering them for a build, it's worth discussing quality control processes and how they handle plan compliance before committing.
What do customers say about Dumac's pricing?+
Only one review directly addresses cost, describing the pricing as reasonable for a caravan safety switch replacement job. Reviews don't mention pricing for other job types like new builds or air conditioning installs. The business is GST registered, so they can provide formal tax invoices. As always with electrical work, getting a written quote before the job starts is the safest approach regardless of what others have paid.
