Tips for Picking a Company You'll find refinishing and tub lining companies in the yellow pages and on the Internet, but the best advice is to act as you would when hiring any contractor -- by asking lots of questions. First of all, get recommendations from friends and neighbors. Also obtain references from the salesperson (and check them!), and find out how much training the installer has had (Re-Bath requires a nine-day course). "Word-of-mouth is our best advertising," says Davis Glassberg, of Luxury Bath Systems. "Ask how long the company has been in business, too," he adds. If you're considering a tub liner, determine whether the company has your exact tub model before you sign a contract. Call the headquarters where molds are made if you don't get a convincing answer. Also avoid companies that use PVC liners. They are less expensive, but they tend to yellow with age, and they are thinner than acrylic. Because there's no regulation or certification of this industry, ask for product-safety data sheets on adhesives and any other chemicals that will be used. Different refinishers use different chemicals, and you should be skeptical of any claim that the solvents are "safe." They may well be after they've been washed away or once they have dried, but make sure the refinisher ventilates the room thoroughly, and cautions you to stay away from the work area until the fumes are gone. If you follow these suggestions, you will get a safe installation as well as a tub that looks brand-new.
