Wow! It looks like you installed a new carpet! Thank you!
'I would like to thank you for making my old carpets look brand new! I have never seen such a great job! Also, I hired you because of allergy problems I have been plagued with for more than a year...I am a new woman in health and 'new looking' carpets. Prior to his cleaning I was seriously thinking about removing old, tired, stained carpets, no need to now, if you clean once or twice a year maybe it'll be another 20 years before I replace carpets.'
'Thank you - what a pleasure to do business with a company that knows what customer service is all about. You will definitely get referrals from us. You've got it right - just don't change!
