Question 1

Why does my toilet wobble?

Accepted Answer

A wobbly toilet is almost always caused by a failed wax ring seal or loose floor bolts — and it's important to fix it promptly before water damage occurs beneath your floor.

The most common cause is loose closet bolts. These are the two bolts (called "closet bolts" or "Johnny bolts") that anchor your toilet to the floor flange. Over time, the plastic nuts can loosen or the bolts can corrode, allowing the toilet to rock. Sometimes this is a simple fix — tightening the nuts carefully (without ove

Question 2

Why is my bathtub drain gurgling?

Accepted Answer

A gurgling bathtub drain is almost always a venting problem — air is being pulled through the water in your drain trap because the plumbing system can't breathe properly.

How Drain Venting Works

Every drain in your home has a P-trap (the curved pipe that holds water to block sewer gases). For water to drain smoothly, air needs to enter the system through a vent pipe that runs up through your walls and exits through your roof. When that venting is inadequate or blocked, draining water creates a

Question 3

Why is my shower pressure so low?

Accepted Answer

Low shower pressure is typically caused by mineral buildup in the showerhead, water pressure issues in your home's plumbing system, or problems with the shower valve or pipes. The most common culprit in Ottawa's hard water areas is calcium and lime deposits clogging the showerhead openings.

Start by removing and cleaning your showerhead - unscrew it and soak it overnight in white vinegar to dissolve mineral deposits. If buildup is severe, use an old toothbrush to scrub the holes clean. Many Ott

Question 4

Why is my shower grout turning black?

Accepted Answer

Black grout in your shower is typically caused by mold and mildew growth, which thrives in the warm, humid environment of bathrooms. This discoloration occurs when moisture gets trapped in porous grout lines and isn't properly ventilated or cleaned regularly.

Mold and mildew are the primary culprits behind black grout. These fungi feed on soap residue, body oils, and organic matter that accumulate in grout lines. Poor ventilation exacerbates the problem by allowing moisture to linger after show

Question 5

Why does my toilet keep clogging?

Accepted Answer

Frequent toilet clogs usually stem from one of several common issues: low water flow, improper items being flushed, or problems with the toilet or plumbing system itself.

The most common culprit is flushing inappropriate items down the toilet. Even products marketed as "flushable" like wet wipes, feminine hygiene products, or excessive toilet paper can cause recurring clogs. These items don't break down quickly and can accumulate in your pipes or catch on rough spots in older plumbing.

Question 6

Why is my vanity countertop cracking?

Accepted Answer

Vanity countertop cracks typically develop from structural movement, improper installation, or material stress over time. The most common cause is inadequate support underneath the countertop, especially around sink cutouts where the material is weakened.

Structural issues are often the primary culprit. If your vanity cabinet is settling, the house is experiencing foundation movement, or the countertop wasn't properly supported during installation, stress cracks will appear. This is particularl

Question 7

Why does my bathroom drain smell bad?

Accepted Answer

Bad bathroom drain smells are typically caused by dried-out P-traps, buildup of hair and soap scum, or sewer gas escaping through compromised seals. The most common culprit is a dry P-trap - the curved section of pipe under your drain that should always hold water to block sewer gases.

If a bathroom isn't used regularly, the water in the P-trap can evaporate, allowing sewer gases to rise up through the drain. This is especially common in guest bathrooms, basement bathrooms, or floor drains. The

Question 8

Why is there mold on my bathroom ceiling?

Accepted Answer

Mold on your bathroom ceiling is almost always caused by excess moisture and inadequate ventilation. When hot, humid air from showers and baths rises to the ceiling, it condenses on the cooler surface, creating the perfect breeding ground for mold spores.

The most common culprit is poor ventilation. Many Ottawa homes have undersized exhaust fans or fans that aren't used consistently. Your bathroom fan should move at least 1 CFM per square foot of bathroom space, and it should run during showers

Question 9

Why is my bathroom always humid?

Accepted Answer

Bathroom humidity is typically caused by inadequate ventilation combined with moisture from hot showers, baths, and daily use. Without proper air circulation, water vapor gets trapped and creates that persistently damp feeling.

The primary culprit is usually an undersized or poorly functioning exhaust fan. Many older Ottawa homes have builder-grade fans that move only 50-80 CFM (cubic feet per minute), which isn't sufficient for most bathrooms. The fan should be sized to move the air volume of

Question 10

Why is there water on my bathroom floor after showers?

Accepted Answer

Water on your bathroom floor after showers is typically caused by inadequate shower containment, poor ventilation, or failing seals around your shower enclosure. This is a common issue that needs prompt attention to prevent water damage to your subfloor and potential mold growth.

The most frequent culprits are failing caulk or grout around your shower base, tub, or glass doors. Over time, these seals deteriorate and allow water to escape onto your bathroom floor. Check the caulking around your

Question 11

Why is water leaking behind my shower wall?

Accepted Answer

Water leaking behind your shower wall typically indicates a failure in your waterproofing system - either damaged grout, failed caulking, or compromised waterproof membrane behind the tiles.

The most common culprits are deteriorated grout joints between tiles and failed caulk seals around the tub or shower pan edges. Over time, these materials crack and shrink, creating pathways for water to penetrate behind the wall surface. Once water gets behind the tiles, it can cause significant damage to

Question 12

Why is my bathroom exhaust fan not working?

Accepted Answer

A non-working bathroom exhaust fan is usually caused by electrical issues, a burned-out motor, or blockages in the ductwork. Start by checking if the fan is getting power, then inspect for physical obstructions or motor problems.

First, check the electrical connections. Make sure the wall switch is working by testing it with a voltage tester or trying a different electrical device in the same circuit. Check your home's electrical panel for any tripped breakers. If the fan has been working inter
