The last few years have seen improvements in the way that natural stones are being quarried, processed, and prepared for installation into the home. Dupont is now offering an extended warranty program for their StoneTech Bulletproof sealer. This warranty guarantees protection against food-related stains for 15 years. During this period if issues or concerns arise with the seal on the material, DuPont will offer repair or replacement services through their warranty guarantor. Exquisite Stone is an approved dealer for this warranty, and offers it for $175 with any kitchen installation. At less than $20 per year for the life of the warranty, this peace of mind is a nice reassurance that your countertop investment is being protected. Please visit Exquisite Stone for more details.
