Looking for outdoor fireplaces & fire pits in Atlantic Heights in Portsmouth, NH? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Portsmouth and the rest of Rockingham County, NH from our Boston base. Portsmouth's historic brick downtown requires soft lime mortar and traditional joint profiles.
Housing in Atlantic Heights in Portsmouth includes homes sitting on fieldstone and block foundations, and New England's 60–100 freeze-thaw cycles a winter is what wears this masonry down. That is why our outdoor fireplaces & fire pits work starts with understanding what your building is made of — brick type, stone, mortar hardness, and drainage — before we price anything. An outdoor fireplace or fire pit turns a patio into a space you use most of the year. We build with firebrick cores, correct flue sizing, and finishes that tie into the rest of your masonry.
