Dripping Bathroom Faucet Repair

A dripping bathroom faucet wastes water and money. At one drip per second — a typical slow drip rate — a faucet wastes approximately 20 litres of water per day, or 7,300 litres per year. At Peel Region water rates, this represents a measurable addition to a household’s annual water bill. A cartridge replacement or seat washer repair stops the drip completely and typically costs far less than a year of that water waste.

Most bathroom faucet drips originate from a worn cartridge (in single-handle and cartridge-based dual-handle faucets), a worn seat washer and O-ring (in older stem-type valves), or a failed ceramic disc (in high-end dual-handle disc faucets). We identify the valve type during the service call, confirm the correct replacement component, and complete the repair in 45 to 90 minutes in most cases.

Peel Region’s hard water accelerates faucet cartridge wear. Calcium scale deposits inside the cartridge body increase friction on the moving parts, shortening the cartridge lifespan from the manufacturer’s expected 10 to 15 years to 5 to 8 years in high-hardness supply areas. Homeowners with recurring faucet cartridge failures should consider a water softener as a longer-term solution to appliance and fixture wear.

Bathroom faucet leaks at the base of the spout — where the spout connects to the faucet body — are caused by deteriorated O-rings on the spout tube. These O-rings seal the connection between the rotating spout and the fixed faucet body. Water appearing at the base of the spout only when the faucet is running, and stopping when turned off, is the characteristic sign of spout O-ring failure. Replacement is a straightforward repair requiring the spout to be lifted off the faucet body after the retaining clip is released.

Bathroom Faucet Cartridge Replacement

Faucet cartridge replacement is the most common bathroom faucet repair. The cartridge is the internal valve mechanism inside a single-handle faucet that controls both flow rate and temperature through a single rotational motion. When the cartridge wears, the faucet either drips from the spout, leaks from the base of the handle, or becomes difficult to adjust — requiring excessive force to control temperature.

We carry replacement cartridges for the most common bathroom faucet brands on our service vehicles. Moen cartridges are identified by the faucet series (1225B, 1222B, 1200 series, and others). Delta cartridges include the RP19804, RP70537, and common 13/14 series. Kohler GP77759 and Pfister cartridges are also stocked. For faucet brands or models not in our vehicle stock, we source the cartridge same-day from our Mississauga wholesale supplier in most cases.

After cartridge replacement, we run both hot and cold water through the faucet to confirm no drip at the spout or base, test the temperature range from full cold to full hot, and confirm the handle position indexing is correct before completing the service call. If a cartridge replacement does not fully resolve the drip — which can occur when the valve seat is also worn — we advise on whether valve seat resurfacing or faucet replacement is the more cost-effective next step.

Ceramic disc faucets — a premium faucet type that uses two ceramic discs to control flow and temperature rather than a cartridge — are more resistant to Mississauga’s hard water than standard cartridge faucets because the ceramic disc material is harder and less reactive to calcium than plastic cartridge components. When a ceramic disc faucet does develop a drip, it typically requires a ceramic disc replacement kit rather than a standard cartridge.

Bathroom Faucet Replacement — All Configurations

When a bathroom faucet is beyond economical repair — typically after 15 or more years of service, or after two or more cartridge replacements within a few years — replacement is the better long-term value. A new faucet installation delivers a manufacturer warranty, a fresh cartridge at full service life, and the option to update the finish and style of the bathroom hardware.

We install all bathroom faucet configurations: single-hole (one hole for the faucet body), centerset (three holes on a 4-inch spread, faucet covers all three), widespread (three holes on 6 to 16-inch spread, faucet body and handles separate), and wall-mount (supply connections at the wall, faucet body mounts to the wall above the sink). Each configuration requires different supply line lengths and angle stop positions.

For supply-your-own faucet installations, we handle the complete installation including supply line connection, drain stopper linkage installation, and confirmation of zero leaks. We typically recommend replacing the bathroom sink supply lines and drain stopper assembly at the same time as a faucet replacement — all components are already disconnected, and the incremental cost is small.

Matching faucet finish to existing bathroom hardware is an important consideration when selecting a replacement faucet. Polished chrome is the most compatible finish across hardware brands. Brushed nickel and matte black finishes vary between manufacturers — two brushed nickel faucets from different brands may have noticeably different hues. We advise homeowners to match hardware from the same manufacturer line when uniformity across all bathroom fixtures is a priority.

Faucet Aerator Cleaning & Hard Water Maintenance

The faucet aerator is the screen assembly at the tip of the faucet spout. It mixes air into the water stream to produce a smooth, splash-free flow and determines the faucet’s rated GPM (gallons per minute) output. In Mississauga’s hard water supply, aerator screens accumulate calcium scale within 12 to 18 months, reducing flow and producing a distorted, multi-stream spray pattern.

Aerator cleaning involves removing the aerator housing (typically by hand or with a strap wrench), disassembling the screen stack, soaking the components in white vinegar for 30 to 60 minutes, and reassembling. When scale accumulation has blocked more than 50 percent of the screen area, aerator replacement with a new unit is faster and more effective than cleaning.

During any bathroom faucet service call, we inspect the aerator condition and advise on cleaning or replacement. For homeowners experiencing rapid aerator scale buildup, we discuss the water softener and treatment options that address the root cause in Peel Region’s high-hardness supply area.

Swivel aerators and pull-out aerators on bathroom faucets designed for face washing or hair rinsing require a different cleaning approach than standard fixed aerators. The swivel mechanism can trap scale at the pivot point, causing the aerator to seize in one position. We confirm the aerator type and mechanism during the service call and clean or replace accordingly — replacement aerators cost $5 to $25 and restore full swivel and flow function.

Frequently Asked Questions

Q: How much does a dripping bathroom faucet repair cost in Mississauga?

A: Bathroom faucet cartridge replacement typically costs $80 to $180 including the cartridge and labour. Stem-type valve seat washer replacement costs $60 to $120. Full faucet installation (supply-your-own faucet) costs $120 to $250. Call 416-910-2550 for a free estimate.

Q: How do I know if I need a new faucet or just a cartridge replacement?

A: If the faucet is under 10 years old and the only symptom is a drip at the spout, cartridge replacement is the right first step. If the faucet is over 15 years old, has had two or more cartridge replacements, leaks from the base of the faucet body, or has visible corrosion on the spout or handles, replacement is the more economical long-term choice.

Q: How long does bathroom faucet replacement take?

A: Standard bathroom faucet replacement — removing the old faucet and installing a new one — takes 45 to 90 minutes for most single-hole and centerset configurations. Widespread faucets with separate hot and cold handles take 90 to 120 minutes. We complete the full job including cleanup and leak confirmation in a single visit.

Q: Does Delex Plumbing supply the faucet, or do I need to purchase it myself?

A: You can supply the faucet yourself for installation, or we can supply and install a faucet from our preferred brands. Supplying your own faucet gives you the broadest choice of style and finish. We recommend confirming the configuration (single-hole, centerset, or widespread) matches your vanity top before purchasing.
