It is very important to have a professional shower restoration, cleaning and sealing service in order to maintain the quality of shower. These steps can be very helpful in prolonging the life of a shower. Overtime caulk and grout in the bathroom become very hard and with regular movement grout cracks and forms holes. This results in the shower getting cracked in caulk and grout leading to the formation of mildew and mold. This is something that needs to be taken care of and if you fail to do so then you might be reducing life expectancy of your shower. When do you need a Shower Renovation? Whenever you take a shower, water slowly gets into the cracks where it gets soaked up by the sheetrock found behind tiles. This causes the shower walls to turn spongy resulting in larger problems. Mildew and mold cannot be removed with regular scrubbing because it grows from the rear side of the grout and caulk line. Therefore, it is very important to treat this condition as soon as possible. If this condition is left untreated, water will continuously get into the shower walls and the tiles will gradually pop off. However, repairing the shower at this point of time can turn out to be a little expensive. This is when you need to go for a shower refurbishment.
