Fantastic, efficient, friendly service. Restored an oven we had thought unusable to full, gleaming working order. The previous owner of our house had left us with an oven layered with archaeological levels of burnt on dirt and grease. Not feeling remotely up to the challenge of dealing with this ourselves (Mr Muscle fainted at the sight), we contacted Martin from Oven Wizards, who came round the following weekend. Although also shocked at the state of the thing ("one of the ten worst" he'd seen, we were proud to find out), he set to work with gusto, even cheerfulness. To our amazement (we were all watching this miracle take place), after dismantling, scraping, degreasing and some other wizardry, the oven looked as good as new. We were able to use it straight away (and did that evening); there were no unpleasant fumes while cooking, or through any of the process. While ours was an extreme case, I'd recommend the service to anyone whose oven (or extractor hood, or hob, which we also had cleaned) is getting beyond normal household cleaning. Since the cleaning gets into areas we can't usually reach (interior panels were removed and cleaned separately), we'll be back for regular services (though hopefully with a less grimy oven!). Martin was not only very capable and thorough, but also friendly and able to give useful advice. He left both the oven and the kitchen floor beneath it spotless.
