Toilet Installation & Repair FAQ
How long does toilet installation take?
A straightforward toilet replacement takes about an hour in a Southern NH home. If the flange needs repair or there is subfloor damage, it may take longer.
My toilet is running constantly, what's wrong?
Usually a worn flapper, a faulty fill valve, or a float set too high. All are inexpensive repairs. A running toilet can waste 200 or more gallons per day, so it is worth fixing promptly.
Can you install a bidet toilet seat?
Yes. Most bidet seats require a nearby GFCI outlet in addition to the supply line connection. A.J. LeBlanc Heating handles both.
Should I repair or replace my toilet?
If the porcelain tank or bowl is cracked, or the toilet has recurring clogs, leaks, or hard-to-source parts, replacement may make more sense. We inspect it and compare repair with replacement. For newer toilets with minor issues, repair makes sense.
