Resilvering is a process that can help restore old mirrors to its original appearance. We recommend hiring a home service pro to get the job done, since the process is fairly complex and incorrect methods could do more damage than good to the mirrors.
Got a mirror installed in our basement gym. Ordered through their rep over the phone, paid 50% down and within 2 weeks, got it installed and service was great. Everything as agreed. No complaints, just praise. Thanks.
