Tuckpointing in Tower Grove and Shaw, St. Louis

Most brick in Tower Grove and Shaw dates from roughly 1890 to 1915, which puts it squarely in the soft common brick era. Joints here fail first on the south and west elevations and on the alley side, where nobody looks. We quote by elevation so you can start with the wall that is letting water in and stage the rest.

The buildings here

Dense blocks of two-family brick flats and brick single family homes built between about 1890 and 1915, with front bay windows, cut stone sills and lintels, corbelled cornices, rear wooden porches and alley garages behind almost every property.

What the brick in this part of town is like

The blocks running off Tower Grove Park were built out fast in the twenty-five years either side of 1900, mostly as brick two-family flats with a second flat stacked over the first. Walk Flora Place, Russell, Magnolia or any of the numbered streets in Tower Grove South and the pattern repeats: a bay front, cut stone sills and a flat stone or steel head over each window, a corbelled cornice at the roofline, and a shallow flat roof behind a low parapet.

That parapet is the detail that brings most owners here to us. It is masonry exposed on both faces with the roof membrane turning up behind it, and on a lot of these houses the original coping is gone or cracked. Water goes straight into the top of the wall and works down through the cornice brick, which is corbelled out and has the least support of anything on the elevation.

Soft brick and the wrong mortar

Nearly everything in Shaw and Tower Grove predates 1930, so the common brick is soft by modern standards. Around here a good deal of it has already been repointed once, in the 1970s or 1980s, with a gray portland mix that is far harder than the brick. You can see the result on side walls: proud gray joints standing out from a brick face that has eroded back behind them, and spalled units scattered through the wall.

Repointing over that work means cutting out the hard mortar carefully, which is slower than cutting out soft lime mortar and costs more. We price it honestly rather than quoting a soft-mortar rate and discovering it on day two.

Access, parking and scheduling

The gangways between these flats are narrow, often three or four feet, and both buildings drain into them. That gangway wall is usually the wettest masonry on the property and the hardest to get a scaffold into. Alley access makes rear work simple. Front work on blocks near the park competes with festival and farmers market traffic on weekends, so we schedule street-side elevations midweek where we can.

What matters locally

Historic district review applies on much of it

Shaw and the Tower Grove Heights and Tower Grove East areas include City of St. Louis local historic districts, where the Cultural Resources Office reviews exterior work and district standards can govern mortar and joint profile. We check your address before quoting.

Front elevations were built to be seen

The street face of a Shaw flat usually carries better fired face brick with tight joints, while the side and alley walls are softer common brick with wider joints. Those two walls need different mortar mixes and often different pricing per square foot.

Alleys are the access advantage here

Almost every block has a working alley, so rear scaffold and material drops are straightforward. Front elevations are another matter, because the houses sit close to the sidewalk and street parking is tight around Tower Grove Park on weekends.

Rear porches load the back wall

The wooden rear porches on these flats bolt into the brick and leak at their ledger connections. Rotted porch framing and failed brick at the porch pockets show up together, so we look at both while the scaffold is up.

Tower Grove and Shaw questions

Does work in Shaw need historic district approval?

Often yes. Parts of this area sit in City of St. Louis local historic districts, and exterior masonry work there is reviewed by the Cultural Resources Office. Standards can cover the mortar mix, the joint profile and the tooling. We check the address against the city's district map before quoting and build the review time into the schedule.

Why does the front of my house look so different from the sides?

It was built that way. Builders here used their best fired face brick with thin, neat joints on the street elevation and cheaper common brick with wider joints on the sides and rear. The two walls absorb water differently and need different mortar. A single square foot price for the whole house usually means somebody did not look closely.

Can you work from the alley?

Yes, and it usually saves you money. A rear elevation with alley access takes scaffold and a material drop without closing any street. Front elevation work on these blocks is tighter, and depending on the setback we may need a sidewalk permit from the city for the scaffold footprint.
