Got Questions?

Frequently Asked Questions

How much does it cost to install or repair a toilet in 2026?

A standard toilet repair (like a fill valve or flapper replacement) typically ranges from $150 to $300. For a new installation, labor costs usually fall between $250 and $1500. This price assumes the floor flange and shut-off valve are in good condition; if the subfloor is rotted or the flange is broken, we provide an updated estimate for the structural work.

Why is my toilet constantly "running" even when not in use?

This is usually caused by a degraded flapper that no longer creates a watertight seal, or a fill valve that is set too high, allowing water to spill into the overflow tube. It’s a silent leak that can waste up to 200 gallons of water a day. Replacing these internal components is a fast, cost-effective way to stop the waste.

What causes water to pool around the base of the toilet?

A puddle at the base almost always points to a failed wax ring seal. When the wax ring stops sealing the connection between the toilet and the sewer flange, water escapes every time you flush. This must be addressed immediately to prevent the wooden subfloor from rotting and causing the toilet to eventually collapse.

Why does my toilet rock or wobble when I sit down?

A rocking toilet is often caused by an uneven floor or a closet flange that sits too high. However, it can also mean the floor underneath has become soft due to a long-term leak. We level the unit and secure it with shims and new closet bolts to ensure it’s stable and the seal remains intact.

How long does a standard toilet last?

The porcelain itself can last 50 years, but the internal moving parts usually fail every 5 to 7 years. If your toilet is an older model (pre-1994), it likely uses 3.5 to 7 gallons per flush. Upgrading to a modern High-Efficiency Toilet (HET) that uses 1.28 gallons per flush can significantly lower your monthly water bill.

Can you fix a cracked toilet bowl or tank?

No. Porcelain cracks are structural failures and cannot be safely patched. Even a hairline crack can suddenly burst under pressure, leading to a catastrophic flood. If we identify a crack in the tank or the bowl, we recommend an immediate replacement of the entire unit.

Why is my toilet not flushing completely?

This is often caused by low water levels in the tank, a clogged "jet" hole at the bottom of the bowl, or a partial blockage in the trap. Over time, calcium deposits can also clog the rim holes where water enters the bowl. We clear these passages and adjust the lift chain to ensure a full, powerful flush.

What is the benefit of a "Chair Height" or "Right Height" toilet?

These models sit about 2 inches higher than standard toilets (approx. 17-19 inches). They are compliant with ADA standards and make sitting and standing much easier for people with knee or back issues. They have become the standard choice for most master bathroom upgrades in 2026.

Do I need to replace the shut-off valve during a new installation?

If the valve is an old "multi-turn" style and feels stiff or shows white mineral crusting, yes. These valves often leak the moment you try to use them after years of sitting idle. We install modern quarter-turn ball valves that are much more reliable and easier to operate in an emergency.

Do you provide 24/7 emergency service for toilet backups?

Yes. A toilet that is overflowing or completely backed up is a major sanitary issue. We offer 24/7 emergency response to clear the blockage, inspect the line with a camera if necessary, and ensure your bathroom is safe and functional again.
