Blue Diamond Window Cleaning in Peterborough has provided efficient window cleaning services for more than 27 years. The key to our success is that we clean the window frames through brushing and power-washing so that rain water doesn't dirty them. You can rest assured that our staff is highly professional and fully trained and our services are fully bonded and insured. We carry our own water and our own chemicals in our modern fleet of vans, for your convenience. To top it off, we don't need you to be home while we clean your windows. We will leave the invoice at your home after we've done our job. If you're happy, pay us, if you're unhappy, call us. Contact us today to take your first step towards squeaky clean windows. more...
