About us

Alteration Specialists was first established in 1987 and has been providing the Palmerston North and Manawatu with high quality construction ever since.
Our key goal at Alteration Specialists when undertaking any alteration/extension work is to make sure the renovation is in keeping with the style of the house. If we have done our job properly, you shouldn’t be able to tell if we have been there – there should be a seamless flow between the alteration and the original building.
“Alterations and renovations are what we specialise in and working within clients homes is something we are very experienced at. We know that a poorly maintained site can be hazardous to homeowners and children. Respecting you and your home is something we take seriously and insuring a clean, tidy and safe work site is something we pride ourselves on.”
