The Renovate service is extremely thorough, and does involve stripping every drum down to its component parts.
I always allow at least a week turnaround time for a 5 piece kit after drop-off to allow me time to complete the job properly.
The cleaning process can get very dirty, which is another reason that I do all servicing work in my workshop rather than in your home.
This also ensures that I have all of my tools and spares to hand.
* Drum kit servicing prices quoted apply to a standard 5 piece drum kit with a set of hardware (hi hat stand, bass drum pedal, snare stand and 2 x cymbal stands).
Larger kits may cost more to service - please ask for a quote.
