Masonry Repair for Greenfield's Postwar Homes and Condos

Brick Repair, Tuckpointing and Chimney Repair for Greenfield Homes and Condos

Our Greenfield work covers chimney repair and rebuilds, tuckpointing and repointing with mortar matched to the original and softer than the brick, brick repair and replacement, rusted steel lintel replacement, veneer flashing and weep holes, sills and copings, masonry stoops, steps and retaining walls, and concrete steps and flatwork. For foundation walls and the larger condo and apartment buildings we handle masonry waterproofing and building restoration. Greenfield’s own permit list shapes several of these jobs. The City’s list, dated February 2026, includes window and door header changes, concrete steps and patios, foundation repairs and drain tile, retaining walls over 24 inches and exterior alterations, and it sends wood-burning units, stoves and fireplaces through an HVAC permit. The list says it is not all inclusive, and in Greenfield the contractor applies for the permit on contractor work, through the City’s online system, not the homeowner.

Veneer, Lintels and Chimneys on Greenfield’s Postwar Stock

About 55 percent of Greenfield’s homes were built between 1950 and 1979, and where those houses carry brick veneer, it depends on what is behind it. Brick Industry Association guidance for veneer calls for at least a 1 inch air space behind the brick and flashing and weeps at the base, over lintels and heads, under sills, at roof lines and where a stoop meets the wall; white bloom that keeps coming back after the first year points to water getting in. The association calls sills and copings among the most vulnerable spots on a wall; they need to slope and be flashed beneath. Over windows and doors, steel lintels rust, and rust can take up to ten times the volume of the steel it came from, cracking the brick above; the association calls for flashing them and, in harsh climates, galvanizing or maintaining them. On Greenfield’s condo and apartment buildings those lintels can run window after window. Exterior revisions on multi-family and commercial buildings go to the Plan Commission and then the Common Council, with elevations and a color rendering, so on those buildings we confirm with the City whether a repair counts as a revision before work starts. When we rebuild a chimney, Brick Industry Association guidance calls for Grade SW brick, Type N mortar, flue liners to ASTM C315, base flashing at least 4 inches up and counter-flashing lapping it by 3 inches, and it prefers a prefabricated cap to one cast in place. Winters add the stress: NOAA readings at Milwaukee Mitchell airport, not Greenfield itself, average 74.8 days a winter that cross freezing, in a range of 51 to 94 (winters 2015-16 to 2024-25).

Greenfield’s Older Cream Brick and 1930s Revivals

An older layer existed in small numbers. Patch’s 2011 list, drawn from Wisconsin Historical Society records, named four cream brick buildings from 1859 to 1872, including a former winery on Forest Home Avenue that was a residence from 1940, and a 1930s revival cluster on S 44th Street, S 46th Street, S Schauer Avenue and W Vollmer Avenue included brick houses from 1932 to 1941 and two limestone Tudor Revivals on Vollmer. Cream City brick was fired from Milwaukee-area lake clay high in calcium and magnesium and is soft and porous; sandblasting damaged it, and chemical washes are the accepted way to clean it. At Trimborn Farm, now in Greendale, local limestone was burned into lime at up to 200 barrels a day until Portland cement ended the trade. The National Park Service warns that hard repointing mortar on soft brick trapped water until the pressure popped the faces off the bricks, so repointing mortar has to be matched to the original, softer and more permeable than the brick and no stronger than the original mortar, with its sand matched, as in our historic mortar and stone matching work. Brick Industry Association guidance matches replacement brick for size and color range against a sample panel, and warns that a hard brick set next to a soft one cracks the softer; we never promise an exact match. We found no National Register listing in Greenfield, and before exterior work we confirm with the City whether any design or landmark review applies.

Masonry and Permit FAQs for Greenfield, WI

Does tuckpointing need a permit in Greenfield?

Greenfield’s permit list does not name tuckpointing, brick repair, chimney work or veneer either way, and it says the list is not all inclusive. That does not make the work permit-exempt, so we confirm permit needs with Greenfield Inspection Services (414-329-5325; the City’s permit list gives 414-329-5330 for questions) before work starts. Where a permit is needed on contractor work, the City requires the contractor to apply for it, so it is our job, not yours.

Does replacing a rusted lintel need a permit in Greenfield?

Possibly. The City’s permit list includes window and door header changes, and a lintel is the steel that carries the brick over a window or door, so we confirm with Inspection Services whether a lintel replacement on your house falls under that line before work starts. Rust can take up to ten times the volume of the original steel and crack the brick above, and the Brick Industry Association lists rust building up on lintels among the signs a professional engineer should look at.

How deep does a stoop footing go in Greenfield?

On a one- or two-family house, Wisconsin’s Uniform Dwelling Code, SPS 321.16, puts footings for foundations, landings and stoops below the frost line or at least 48 inches below grade, whichever is deeper, unless a code exception applies. Greenfield’s permit list includes concrete steps, so a rebuilt concrete stoop needs a City permit, and for any other stoop we confirm permit needs with Greenfield Inspection Services before work starts.

Does a retaining wall need a permit in Greenfield?

Retaining walls over 24 inches are on the City’s permit list. For lower walls we still confirm with Inspection Services before work starts. Brick Industry Association guidance for garden and retaining walls calls for Grade SW brick, Type M or S mortar, weeps or drains to relieve water behind the wall, and no untested salvaged brick.

Is my Greenfield house under historic preservation review?

We found no National Register listing in Greenfield. Before exterior work we confirm with Greenfield Inspection Services whether any design or landmark review applies. Condo, apartment and commercial buildings are different: exterior revisions there go to the Plan Commission and then the Common Council, with elevations and a color rendering, which the City puts at about 45 days for basic changes.

When is a crack in brick a structural problem?

The Brick Industry Association says a professional engineer should investigate cracks wider than about 0.075 inch, cracks through several bricks, stepped or diagonal cracks, widespread spalling, rust building up on steel lintels or shelf angles, and brick that has moved out of plane. We do not diagnose foundations; when we see those signs on a Greenfield home, we document them and recommend an engineer’s assessment before any masonry repair.
