Community❓Common Questions
Yes, the City of St. John's requires a plumbing permit for new installations. In 2026, the minimum plumbing permit fee is $42.24, or $18.48 per fixture if part of a larger renovation.
While base wages for plumbers in St. John's average around $31.26 per hour, homeowners should expect to pay contractor billable rates between $85 and $145 per hour for professional installation services.
Given the high frequency of power outages during North Atlantic storms, a battery backup is highly recommended. It typically adds $500 to $1,200 to the total project cost but prevents basement flooding when the primary electric pump fails.
St. John's often has rocky or clay-heavy soil. If a new sump pit must be excavated through solid rock or thick concrete slabs, labor costs can increase by $500 to $1,000 due to the need for specialized jackhammering equipment.
