A surface clean would not have touched this one. The soiling had been sitting in the fibre for a long time and the odour had built into it. This is what a professional carpet cleaner actually does with a carpet in that state.

The before photo above is a recent Gold Coast job. One area of carpet, a bedroom and the doorway into it, had been heavily soiled for some time. The discolouration you can see was only part of it. There was a strong odour in the room that had worked its way right down into the fibre and the backing, which is what happens when soiling is left for months rather than days.
Three steps brought it back. First, a full stain treatment across the whole soiled area, not just the darkest patches, so the soiling released from the fibre instead of being smeared around. Second, an antibacterial treatment flushed through the carpet to deal with what was causing the odour at the source. Third, a proper rinse with the truck mounted extraction unit to pull the treatment, the loosened soiling and the moisture back out. The after photo is the same spot with the wand still on the carpet.
Most disappointing carpet cleaning results come down to one thing: cleaning without treating. A hire machine, or a quick once-over from anyone who skips the treatment stage, works the top of the pile. On a lightly used carpet that is fine. On a carpet like this one, the soiling and the odour are below the surface, so the top looks a little better for a few days and then the same shadowing and the same smell come back as the carpet dries.
Treating first means the products have time to work on the soiling before anything is rinsed. Rinsing with a truck mounted unit rather than a portable means that what has been loosened actually leaves the carpet. The unit pulls far more moisture back out than a hire machine can, so the carpet dries faster and nothing dries back in. This is the part people are really paying a Gold Coast carpet cleaner for, and it is the part that gets skipped when the price looks too good.
Not every heavily soiled carpet comes back this well. A stain that has dyed the fibre, or soiling that has damaged the backing, will leave a mark no matter who cleans it. What we can do is look at the area, tell you what we expect to shift and what we do not, and then do the work properly. In this case the carpet responded well because the fibre itself was sound, it just needed the soiling treated and flushed rather than brushed over.
A heavily soiled single room and a whole house of lightly used carpet are priced very differently, because one of them needs treatment time and the other does not. Our minimum call-out fee is $145 plus GST anywhere in the Gold Coast to Tweed Heads service area. Beyond that, the estimate follows the room count, how bad the worst area is and whether odour treatment is needed. Send us a photo of the worst patch along with the number of rooms and we will give you an honest estimate before anything starts. An estimate, because we do not know exactly what is in the fibre until we see it.
