FAQs
Frequently Asked Questions
Pricing, licensing, emergencies, and the water itself, covered below.
Are you licensed for plumbing work in St. Marys?
Yes, licensed and insured, with permits and inspections handled through the proper authority for every qualifying job, so the work is documented for resale or insurance.
Do you respond to emergencies around town?
Yes. Floods, burst pipes, sewer backup, and no-water calls get urgent response across St. Marys, Kirkton, and the neighbouring Perth countryside, day or evening.
How soon could you replace our water heater?
Commonly same or next day, depending on the unit chosen. We stock standard sizes and quote the swap plainly, including disposal of the old tank.
Can you repipe without wrecking the stone?
Yes, and that is the whole craft of it. Routes are planned through chases and joist bays, openings are minimized and patched, and testing happens before anything closes.
We are outside town on a well. Can you treat the water?
We do that across the rural routes south and west of St. Marys. The well gets tested, then the softener and filtration follow the results.
Is the water here hard enough to need a softener?
Most households find it is, and the kettle usually agrees. A softener sized to your actual hardness protects fixtures, heaters, and skin.
How does your pricing work?
Quotes are free, written, and itemized before any work begins, and they hold unless the scope changes with your say-so.
What areas do you serve from St. Marys?
St. Marys itself, plus Stratford, Kirkton, Thorndale, Embro, Thamesford, and Sebringville, along with the rural roads between.
