Aron Bathtub Refinishing offers Bathtub Refinishing Estimate Chicago IL. Our Bathtub Refinishing service starts with the removal of your drain cover and overflow plate. During these initial steps, we also remove any caulking that exists around the edges of the tub. If you’ve had tub reglazing done in the past, we strip the old glaze from the tub. After your tub is stripped down to its most basic form, we complete any needed repairs. Often times, the bathtub surface will have chips, holes, or cracks in it. We repair these areas with body filler and then sand the surface to a smooth finish.
