Some things can add clear value to a home, while others, like soundproofing, aren’t so clear. Soundproofing is something you cannot see, so unless you are told it is there, you most likely won’t notice it’s there. It can also be fairly subjective; a soundproofed home theater will only be valuable to buyers who want a home theater. Meanwhile, soundproofing to minimize noisy streets or neighbors could be seen as improvements that increase a home’s value since these types of renovations will ensure a homeowner’s peace and comfort.
