Frequently asked questions
How quickly can you respond?
Immediately in an emergency. For everything else, you’ll get an answer within 24 to 48 hours.
Do you work outside Montreal?
Yes. We cover the entire province of Quebec, as well as Ottawa and Gatineau. Travel fees apply outside Quebec.
Do you offer annual maintenance contracts?
Yes. We set up annual maintenance contracts to monitor your systems throughout the year, so you don’t have to worry about it.
I already have a supplier. Why should I call you?
Ask us for a quote—even if it’s just to compare for when you might need it. One quote is good; two are better. And consider the benefits: we don’t just test the water, we also carry out repairs, and we are available at any time.
Do you do residential work?
No. We focus on commercial, industrial, and institutional facilities. Residential water treatment is not among our services.
