Two contractors walk your wall. One quotes you repointing. The other quotes you tuckpointing, for noticeably more money. Both are looking at the same crumbling mortar joints, so why isn't it the same price for the same fix? Because it usually isn't the same job, even though most people selling it use the words like they're interchangeable.
Repointing is the structural fix
Repointing is grinding out the old, failed mortar and packing the joint with new mortar that matches the original in strength and colour. That's it. It stops water from getting behind your brick, and on most London homes that's the entire problem that needs solving. Done properly, a repointing job holds for 30 to 50 years before it needs doing again.
Tuckpointing is repointing plus a trick
Tuckpointing starts with the same repointing step, then adds something extra: a thin, contrasting line of lime putty or fine mortar pressed into the fresh joint, or "tucked" in, to create the illusion of hairline-thin, dead-straight joints. It's a technique masons in England developed to make ordinary brick look like the far more expensive rubbed brick used on high-end buildings. On a heritage London facade with that fine-joint look already built into the original design, tuckpointing is how you preserve it. On a standard brick wall that never had that detail, you're paying extra labour for an effect nobody will notice.
The two get sold as synonyms because the first step is identical and most homeowners never see the wall up close enough to spot the tuck line. We've had customers who paid a tuckpointing price and got plain repointing, and customers who assumed repointing would give them the crisp heritage look and were disappointed when it didn't. Neither is a scam exactly. It's just sloppy language turning into a pricing gap nobody explained.
Check which one your house actually needs
Before you call anyone, go outside with a flashlight and look at your mortar joints up close, ideally on an original, unrepaired section of wall if your house is pre-1950s. If you see a thin, raised, contrasting-coloured line running dead straight down the centre of each joint, that's tuck work, and matching it later means paying for tuckpointing again. If the joints are just plain mortar in one colour, your house was built with standard joints and repointing will restore it to exactly what it looked like originally. That five-minute check tells you which quote you should actually be asking for.
While you're out there, check how bad the mortar itself is. Scrape a joint with a key or a screwdriver. If it crumbles or comes out as dust, water's already getting behind the brick, and that's a job for this season, not next year's. You can see what unmanaged joint failure eventually does to the brick itself in our piece on spalling brick, which is the next stage of the same problem.
Where this stops being a DIY job
Diagnosing which one you need costs nothing and takes ten minutes. Doing the repair yourself is a different story. Matching mortar strength and colour to a wall that's 60 or 100 years old requires testing sample mixes against your actual brick, not eyeballing a bag of pre-mix mortar from the hardware store. Get that wrong and, like we've seen on plenty of older London homes, a hard modern mortar ends up stronger than the brick around it, and the brick starts failing instead of the joint. Tuck work is worse to attempt without training: the tuck line has to be dead straight over an entire wall, by hand, and a wobbly line is more obvious than no line at all.
If your mortar's failing, a repointing assessment will tell you honestly whether you need the structural fix, the structural fix plus tuck lines, or nothing yet. Every job gets priced after we've seen the wall, since the mix, the coverage, and whether tuck work applies all depend on what's actually there. If you already know your home has the heritage tuck detail, our tuckpointing page covers what that process specifically involves.
Frequently asked questions
Is tuckpointing just a fancier name for repointing?
No. Repointing is the mortar replacement. Tuckpointing is that same replacement with a decorative contrasting line added on top. A lot of contractors use the words loosely, which is exactly why quotes for the same-looking wall can come in at different prices.
How do I know if my house has true tuckpointing?
Look closely at an original section of mortar joint with a flashlight. True tuck work shows a thin, raised line in a different colour than the base mortar, running perfectly straight. Plain mortar in one colour means your house never had it.
Does tuckpointing last longer than repointing?
No, both typically hold for 30 to 50 years when done with the right mortar mix. Tuckpointing costs more because of the extra labour for the decorative line, not because it's more durable.
Can I just get repointing on a heritage home instead of tuckpointing?
Structurally, yes, plain repointing protects the wall the same way. You'll lose the fine-joint look if the original brick had it, which matters more on a heritage facade where that detail is part of the home's character.
