Calls are coming in from homeowners all over the city.
"A lot of them are anxious and rightly so, it was a serious event that happened on Friday and it's just giving them some reassurance that it is safe," says Martin De Gouw, the company's managing director.
Master Plumbers, Gasfitters and Drainlayers has seen a surge in calls from all over the country.
"One of our members in Wellington has had the biggest spike in enquiries about that," says Greg Wallace, the company's chief executive officer.
An investigation into what caused the house at Marble Court to explode last Friday is ongoing, the most likely cause according to Fire and Emergency coming from the neighbourhood's reticulated gas supply.
Gas specialists say if you can't smell gas then there's probably no danger - but gas fittings should be checked and serviced annually.
"It take doesn't long, it's not a big cost. You may have to wait for six to eight weeks but it gives you peace of mind and I think that's important for consumers," says Wallace.
That's reassurance in the aftermath of an event no one wants to see happen again.
