Accountability & Trust

Mannion Plumbing & Heating scores well for accountability and trust. They have been in business for 68 years, and they have not had any complaints filed against them with the Better Business Bureau over the past 3 years. In our view, they could improve some more by becoming accredited by the Better Business Bureau.

Online Reviews

When it comes to online ratings and reviews, the company could do better by improving on some of their low reviews on Google, HomeStars, and Yelp. It would be nice to see more reviews for this company. So if you use them, make sure to let everyone know how they did by leaving a review for them on Google, HomeStars, or Yelp.

Warranties & Satisfaction Guarantee

We think it is important that every plumbing company stand behind their work with a parts and labour warranty and ideally a satisfaction guarantee – guaranteeing you the paying customer that the job you pay for is not done until you’re satisfied.

While warranties and satisfaction guarantees are common in some Canadian cities, only 30% of plumbers publically offer them in the Greater Ottawa Area.

Mannion Plumbing & Heating has not published any information publicly about offering a specific warranty or satisfaction guarantee.
