Tuckpointing and Brick Repair in Soulard, St. Louis

Soulard holds some of the oldest brick in St. Louis, much of it laid between the 1840s and the 1880s in soft handmade brick and pure lime mortar. That brick will not tolerate a modern portland mix. Soulard is also a City local historic district, so exterior masonry work goes through Cultural Resources Office review before it starts.

The buildings here

Two and three story brick rowhouses and flats from the 1840s through the 1880s, built wall to wall on narrow lots with shared party walls, flat roofs behind parapets, tall chimney stacks, stone lintels and sills, and dug-out basements with rubble limestone walls.

The oldest brick stock in the city

Soulard was built before most of St. Louis and it shows in the masonry. Blocks around the market, along Allen, Russell, Ninth and Twelfth carry buildings from the 1840s through the 1880s, some of them with handmade brick that predates mechanized brickmaking here. That brick is soft, irregular and porous. It was laid in lime mortar with wide joints, and that combination has worked for over a century precisely because the mortar gives before the brick does.

The buildings sit wall to wall on narrow lots with flat roofs behind parapets and tall stacks rising above them. There are no eaves to speak of and no overhang to keep rain off the face, so the brick takes direct weather on every elevation that is not shared with a neighbor.

What goes wrong here

Three things dominate the work in Soulard. Parapets, because they are wet on both faces, often missing their original coping, and carry the roof membrane turn-up. Chimney stacks, because they are tall, exposed on four sides and frequently shared. And previous repairs, because a lot of the rehab work done here through the 1970s and 1980s used a hard gray mix on brick that was never going to tolerate it. Walls repointed that way show the same pattern: standing joints and an eroded, spalled brick face between them.

Basements add a fourth. Soulard sits low, close to the river, on older dug cellars with rubble limestone walls laid in lime. Those walls need repointing in lime, and sealing them with a cement parge or a waterproof paint simply moves the damp somewhere else.

Working on a street with no room

Practically, the constraint in Soulard is space. There is no side yard to stand a scaffold in. Front elevation work means the sidewalk, and that means a permit for the closure and pedestrian protection during Mardi Gras season and market weekends. Rear access often runs through a courtyard or a gangway a person can barely turn a wheelbarrow in. We look at all of this on the estimate visit and price the access honestly, because it is a real part of what the job costs on these blocks.

What matters locally

Local historic district review is the norm

Soulard is a City of St. Louis local historic district. The Cultural Resources Office reviews exterior alterations, and district standards address mortar composition, joint profile and tooling. Approval time has to sit in the schedule, and a contractor who skips it can cost you a stop work order.

Party walls make it a two-owner conversation

Most Soulard buildings share a wall with the building next door, and often a chimney stack too. Repointing a party wall or rebuilding a shared stack usually needs the neighbor involved, and access to their roof. We raise that early rather than on the morning the scaffold arrives.

The oldest brick in the city is here

Pre-Civil War buildings in Soulard can have handmade brick that is genuinely soft, laid in lime mortar with no portland in it at all. On those walls we recommend a mortar analysis before specifying a mix, because guessing at a building that age is expensive to get wrong.

No side yards, so no easy scaffold

Buildings sit on the lot line with a narrow or nonexistent gangway. Front elevation work generally means scaffold over the sidewalk and a permit for the closure, and rear work often means carrying material through the house or over a courtyard wall.

Soulard questions

What approvals does masonry work in Soulard need?

Two things usually. A permit from the City of St. Louis Building Division for the repair work itself, and review by the Cultural Resources Office because Soulard is a local historic district. District standards can specify the mortar mix and the joint profile, so the scope has to be written before it is submitted. We check the address and handle the submission.

Who pays for a shared party wall or chimney?

That is between you and your neighbor, and it is worth settling before work starts. Physically, a shared stack has to be rebuilt as one piece and a party wall above the roofline has to be pointed on both sides to be worth doing. We can write the estimate so the shared portion is priced separately and you can split it cleanly.

Is a mortar analysis worth paying for here?

On a building from the 1850s or 1860s, often yes. A lab takes a sample of the original mortar, breaks it down and reports the binder and the sand, which tells us the mix and the sand color to match. It costs a few hundred dollars and it removes the guesswork on a wall where a wrong mix will spall the brick face.
