Chem-Dry of Northern Maryland unique approach to carpet cleaning provides a better experience and leaves your home healthier. Chem-Dry by Northern Maryland uses the power of carbonation to extract more dirt and grime from your carpets, giving them a deeper clean. As well, our carbonated cleaning substances only require us to use a fraction of the moisture steam cleaners require. This allows your carpets to dry quicker and helps prevent the growth of mold and mildew under your carpet.
