What we run into most

Real-World Pipe & Fixture Problems We Resolve

We've seen every issue a shower can develop. Here are the problems our clients call us about most often.
🚪

Shower Door Won't Close All the Way

This usually means the frame has shifted out of square or the hinges have loosened enough to change how the door hangs. Forcing it shut can crack the glass or bend the hardware further. We check the frame and hardware together to correct the actual cause.

💧

Water Leaking Outside the Shower Enclosure

Leaks almost always trace back to failed silicone sealant, which typically lasts five to ten years before it dries out and pulls away from the surface. Left untreated, the water works into subfloor and drywall and can lead to mold. We remove the old caulk and apply a fresh seal along every affected edge.

🚿

Low Water Pressure From the Showerhead

Mineral buildup inside the showerhead's spray holes is the most common cause of weak pressure, though a worn valve cartridge can also restrict flow from inside the wall. We identify which cause applies and clean, replace, or repair accordingly.

🌡️

Sudden Hot or Cold Temperature Swings

Unpredictable temperature changes usually point to a worn cartridge or valve that can no longer balance pressure correctly. This is a genuine scald risk, not just an inconvenience. We replace the internal component to restore consistent temperature control.

🧱

Cracked or Missing Grout Around the Shower

Gaps in grout give water a direct path into the wall or subfloor behind the shower. A thin patch over cracked grout will not hold up the same way properly applied grout does. We remove and replace damaged grout rather than covering it over.

💦

Persistent Dripping From the Showerhead

A showerhead that keeps dripping after the valve is fully shut off usually means a worn washer or cartridge inside the valve assembly. Left alone, constant dripping wastes water and can accelerate wear on the valve. We replace the worn component to stop the drip completely.

🧽

Shower Door Sticking or Hard to Slide

Mineral buildup combined with soap residue forms a hardened film in the track that narrows the channel over time. Forcing a sticking door accelerates wear on the rollers and hardware. We clean the track fully before any hardware adjustment so the fix actually holds.

🔁

Shower Repaired Before But Problem Came Back

A door or leak that keeps needing the same type of fix usually has an underlying issue a surface-level repair never fully resolved. Continuing to patch it eventually costs more than addressing the root cause. We diagnose the actual source before recommending another repair.

⚠️

Rust or Corrosion on Shower Hardware

Corroded hinges, tracks, or handles often stain surrounding tile and weaken the hardware's grip over time. Left alone, corroded hardware can eventually fail and let the door come loose from its mounting points. We replace corroded components with properly rated hardware.

Testimonials

Hear From Homeowners We've Helped

Natalie B.

Found the real cause of our leak

We assumed the caulk was fine since it looked okay, but the water test showed the leak was actually coming from behind the valve trim. Core Ontario Plumbing Services fixed the actual source instead of just resealing everything and hoping.

Door finally closes properly

Our shower door had never closed all the way since we moved in years ago. The technician found the frame was slightly out of alignment and fixed it in one visit. Such a small thing but it makes a real difference every day.

Good fix, cartridge took a few extra days

The hinge repair was done same day, but the replacement cartridge for our older shower had to be special-ordered and took a few extra days to arrive. The technician kept us updated the whole time and it works great now.

Honest about repair versus replace

I called expecting to need a whole new shower but Core Ontario Plumbing Services explained the hardware was still in good shape and a targeted repair would do the job. Saved me a lot of money and it has worked perfectly since.

Water pressure back to normal

Our shower pressure had been weak for months and I assumed it was a plumbing issue. Turned out to just be mineral buildup in the showerhead. Ten minute fix and now it feels brand new.

Same-week appointment for an active leak

We noticed water pooling outside the enclosure and called Core Ontario Plumbing Services right away. They got someone out within a few days and explained exactly what caused it before starting any work. Very professional the whole way through.
