The old grille was installed with nails. It took about 30 minutes to remove the old grilled because of the nails. It took my husband 10 minutes to install the new grille. Instructions were spot on. The quality of the grille is superb. Its durable. Solid construction. From what I could see while at the shop, the two guys were working on one vent at a time, which speaks to the quality. More than what I expected. Absolutely worth the price. Everyone who has a generic, white, ugly grille in a high traffic area of the home like I had should know about you.
