Costello Construction is involved in making sure the the town you live in is up to code.  We are involved in tearing down old depleted houses and building new.  Every project we do is put under the microscope and is done efficiently and cleanly.  These two pics are of the latest lot, we took a house down.  The house was older and never built to last.  This is in a nice area and was one of the few houses in such bad shape.
