Masonry & Tuckpointing in Vernon Hills, Illinois
The Census survey counts an estimated five Vernon Hills homes built before 1940. The village building code, meanwhile, says how to clad a chimney, what exterior walls should be built of, and how deep to dig. Between those two facts sits most of what fails on a Vernon Hills wall.
What the Census says about Vernon Hills housing
The American Community Survey (2020-2024 estimates) counts 11,497 housing units in Vernon Hills. An estimated 5 were built in 1939 or earlier; 33 date from the 1940s, 196 from the 1950s and 289 from the 1960s. Only about 4.5 percent of the stock is older than 1970.
Most of it came after: 3,085 units in the 1970s, 1,914 in the 1980s and 1,986 in the 1990s, together about 61 percent of all housing in town. The median year built is 1991, and 3,989 units went up from 2000 on. These are survey estimates with margins of error, so trust the round numbers, not the last digit.
The curve follows the village's history: incorporation on June 16, 1958 with 123 residents and 125 houses, a 1971 annexation that brought a shopping center of about 1.2 million square feet, and further annexations in 1986, 1988 and 1994. The population passed 20,000 by 2000.
For a mason that sets the agenda. Hardly any wall in town is pre-war, so the work is mostly about the age of the hardware: flashing, sealant, lintels, weeps, wall ties and chimney tops. A house from 1979 is 47 years old in 2026; one from the median year, 1991, is 35.
What the Census cannot tell you is what your walls are made of. It does not record exterior wall material for any town, and we found no source that does. Face brick, stone veneer, siding with a brick front: you settle that by looking at the house.
A town whose building code reads like a masonry specification
Vernon Hills adopted a new building code by Ordinance 2026-008 on February 3, 2026, effective March 1. It adopts the 2024 International codes, residential code included, with local amendments, and where the two conflict the village code wins (Sec. 5-56). The amendments are unusually specific about masonry.
Section R330.1 says that, unless the Board of Trustees approves otherwise, structures shall have exterior walls of materials such as face brick, natural or cultured stone, glass, EIFS (spelled EFIS in the code) or other approved non-combustible materials, with soffit, fascia and trim in cedar; above the first floor, cedar or textured fiber-cement siding is allowed. Aluminum and vinyl siding are limited to existing buildings in subdivisions where it was already installed, and barred in subdivisions built only in cedar and masonry. Sec. 5-78 gives office, commercial and retail buildings, and new residential developments of five or more units, a longer approved list.
That is the rule for new work today. We did not find the year each rule first appeared, so do not assume it governed your house.
Why it matters: face brick on a wood-framed house is a veneer, a skin hung on the structure, not the weatherproofing. The Brick Industry Association (BIA) says one wythe of brick will not resist moisture penetration, so flashing must redirect whatever gets through. On a veneer wall the first question is not the brick. It is where the water goes behind it.
The chimney rule: visible chimneys get a masonry jacket
Section 5-77(b) requires every chimney and mechanical vent on a residential building that is visible from any direction to be enclosed. On an outside wall that means a chase clad in full-wythe four-inch nominal masonry or two-inch natural or cultured stone, with its narrowest part no less than two thirds of its widest. A metal flue rising above the chase is covered with a section of clay chimney liner, or another approved means, so the top reads as masonry. Chimneys inside the house get a chase, clad in cultured stone or masonry tile, where they come through the roof.
Section M1801.1.1 says spark arrestors and rain caps coming out of the chase must be black, and the amended R1001.1 asks the same of attachments to a clay liner. Whoever replaces a cap on a Vernon Hills chimney should know that before the part is ordered.
Read this as a map of what may be on your roof. A solid masonry chimney, brick on brick from the firebox up, is one thing. A framed chase with a factory-built metal flue inside and a skin of brick or stone outside is another, and this rule covers the second kind. You cannot always tell from the street. If yours is a clad chase, the cladding behaves like veneer, and the flue inside is a separate part with its own failure modes.
Where Vernon Hills chimneys fail, top to bottom
The cap or crown
A brick-industry weather-resistance checklist is blunt about the top. A cap should overhang the walls with a drip edge, slope away from the flue and sit on flashing. The flue tile should stand at least four inches above it and not be bonded to it: a 3/8 to 1/2 inch gap of resilient sealant lets the tile move without cracking the cap. The failure it singles out is the thin, feather-edged mortar skim, which shrinks, cracks and lets go of the brick beneath.
Flashing at the roof
Roof-to-chimney flashing is normally two parts: step flashing under the shingles and counterflashing from the chimney wall turned down over it. BIA's guidance gives minimum laps of 4 inches along the roof and up the chimney face for the base flashing, with counterflashing lapped at least 3 inches over it. A chimney wider than 30 inches usually needs a cricket. The checklist treats caulk in place of metal flashing as inferior workmanship.
Joints and brick
Freeze-thaw damage starts with saturation. General Shale, a brick manufacturer, describes spalling as the face separating, usually one-eighth to one-quarter inch deep, after repeated freezing and thawing of saturated brick, and says soluble salts speed it up. The checklist names head joints never filled to full depth as the most common source of leakage in brick walls, and favors concave, vee or grapevine joints on chimneys over raked ones, which leave ledges.
The flue
The flue is the part you cannot see from the ground. The Chimney Safety Institute of America (CSIA) procedure, built on NFPA 211, has the sweep look up the flue, recommends sweeping at an eighth of an inch of buildup, checks the crown and flashing, and says to recommend a Level 2 inspection after any sign of a chimney fire.
When to have it looked at
NFPA 211, as CSIA quotes it, says chimneys, fireplaces and vents shall be inspected at least once a year. BIA recommends looking at masonry each season and notes that chimneys, sills and copings may need repair at shorter intervals than walls. A workable routine: binoculars from the ground each season, a sweep or mason up there once a year, and a fresh look after a chimney fire or an appliance change.
What a sound repair scope looks like
- Every component named: cap, flue tile height, flashing, joints, brick, liner, termination.
- Joints raked to a uniform depth, at least twice the joint width and generally three-quarters of an inch, repointed in quarter-inch lifts with Type N, O or K mortar matched to what is there. BIA's triggers: mortar eroded more than a quarter inch, crumbling, voids, hairline cracks.
- Metal flashing, not a bead of sealant.
- Replacement brick matched against a sample panel.
- Black terminations where a cap comes through a chase.
- No coating as a shortcut: BIA says to find the moisture source first and correct deficiencies before any coating goes on.
Lintels, weeps, ties and sealant: the hardware behind the brick
BIA's maintenance note lists the ordinary jobs on a brick wall: replacing failed sealant, repointing, opening weeps, repairing flashing and replacing ties.
- Steel lintels. BIA says galvanized lintels should be considered in harsh climates and that unprotected steel needs periodic maintenance against corrosion, with flashing over the angle and weepholes at lintel level. It notes that many cracks over openings come from excessive lintel deflection. Rust streaks below a window head point at the steel before they point at the mortar.
- Weeps. Open joints at the base and above openings that drain the cavity. BIA says to clear clogged ones with a thin dowel or stiff wire and drill new ones where none exist, without damaging the flashing.
- Wall ties. They hold the veneer to the wall behind it and cannot be seen. BIA lists remedial anchors and ties, where they are damaged or missing, as ordinary maintenance.
- Sealant. Joints at windows, doors and control joints rely on sealant and backer rod, and BIA says to replace torn or inelastic sealant. General Shale adds caulk at porch brick-to-concrete joints.
The bottom of the wall
General Shale's homeowner bulletin lists habits that wreck good brick: sprinklers aimed at the wall, rock salt and piled snow against it, soil or mulch buried against the base, downspouts that dump at the footing. Vernon Hills adds its own rules: a downspout not tied to a storm sewer must discharge onto a splash block, and neither it nor a sump pump may send water across a walk or drive (R801.3, Sec. 5-77(g) and (j)).
Frost, snow and stormwater
The village's own design table for residential construction lists Vernon Hills weathering as Severe, the frost line at 42 inches, ground snow load at 30 pounds per square foot, and an ice barrier as required on roofs.
Vernon Hills sits in the Indian Creek watershed, 38 square miles of southern Lake County, and the village adopts the Lake County Watershed Development Ordinance by reference. For masonry the practical point is water at the foot of a wall and frost under a step. The village code asks new additions for foundation walls at least 42 inches below grade (Sec. 5-77(f)) and stoops wider than two feet to sit on full foundations, not wing walls, unless reinforced (Sec. 5-77(i), written for concrete stoops). If someone proposes rebuilding a brick stoop on a shallow footing, ask how it is founded.
Permits, associations and who pulls the permit
We could not find a village page that says whether tuckpointing alone, or chimney repair, needs a permit. The residential exemption list (R105.2) covers painting, tiling, carpeting, cabinets and similar finish work, shallow prefabricated pools, playground equipment, awnings and small sheds. Masonry repair is not named, so treat the question as open and ask the Building Department, 290 Evergreen Drive, 847-367-3700.
The village's residential permit checklist, revised May 2024, shows a 10 business day review and asks for a plat of survey, the signed homeowner contract, a contractor list and, where one applies, HOA approval. Under Sec. 5-175 securing required permits is the contractor's responsibility. There is no Sunday construction.
Who owns the wall? About 60 percent of units are single-family (4,350 detached, 2,536 attached) and about 27 percent, 3,060 units, are in buildings of five or more. If you own a townhome or condominium, the association may control the exterior. Read your declaration and ask the board before you call anyone.
No local historic review that we could find
The village's Commissions and Committees page lists no historic preservation commission or architectural review board, and the National Register list for Lake County (updated June 3, 2026) shows no entry located in Vernon Hills. We could not search the full code of ordinances, so call this absence of evidence, not proof. The National Park Service says National Register listing places no restrictions on what a private owner may do.
The village's historic Cuneo Mansion and Gardens property was built from 1914 to 1916 for Samuel Insull to designs by Benjamin Marshall, and in October 2025 the village board approved taking it over from Loyola University Chicago. We found no source for its exterior material, so we say nothing about it.
Questions worth asking before anyone climbs a ladder
- Is my chimney solid masonry or a clad chase around a metal flue, and how do you know?
- Where is the flashing, over lintels, at the base and at the chimney, and what shape is it in?
- Which mortar, what joint depth, and a sample panel first?
- Is flashing replaced in metal or sealed with caulk?
- Does the quote name every component, or only say chimney repair?
- Who pulls the permit, and did anyone ask the village whether this scope needs one?
- If a lintel or tie is bad, what is the plan? Repointing fixes neither.
- Who does the repointing? BIA warns that an excellent mason may not be qualified for it.

Questions Vernon Hills owners ask
Do I need a permit to tuckpoint or repair a chimney in Vernon Hills?
We could not find a village page that answers it for tuckpointing alone or for chimney repair, and the residential exemption list does not mention masonry repair. Rebuilding a chimney or changing its enclosure is a bigger question than repointing it. Call the Building Department at 847-367-3700 with your scope, and ask your contractor who pulls the permit.
How old are Vernon Hills homes, and what does that mean for repairs?
In the 2020-2024 American Community Survey estimates, about 5 of 11,497 housing units date from 1939 or earlier, about 65 percent (7,508) were built before 2000, and the median year built is 1991. The usual problems are the parts that wear out before brick does: flashing, sealant, steel lintels, weeps, ties and chimney tops. The Census does not record wall material, so check your own.
Does Vernon Hills have historic district or landmark review for masonry?
None that we could find. The village lists no historic preservation commission, and the Lake County National Register list shows no Vernon Hills entry. We could not search the full code, so that is absence of evidence, not proof. A rule that does apply to you is more likely an association rule or the building code's exterior material standards.
Is my Vernon Hills chimney solid masonry or a brick-clad chase?
You cannot always tell from the street. Sec. 5-77(b) of the village code requires visible residential chimneys to be enclosed in a chase clad in four-inch nominal masonry or two-inch stone, and we did not find when that first applied. If yours is a clad chase, the cladding behaves like veneer and the flue inside is a separate part. A mason can tell from the roof or attic.
How often should a chimney in Vernon Hills be inspected?
NFPA 211, as quoted by CSIA, calls for at least one inspection a year. The Brick Industry Association recommends looking at masonry each season and says chimneys may need repair at shorter intervals than walls, and the village rates local weathering as Severe. A Level 1 inspection is the routine annual level when nothing has changed; CSIA recommends Level 2 after any sign of a chimney fire.
What does a proper chimney crown or cap repair involve?
A brick-industry checklist describes it: an overhanging cap with a drip edge that slopes away from the flue and sits on flashing, flue tile at least four inches above the cap and not bonded to it, and a sealed 3/8 to 1/2 inch gap, instead of a thin mortar skim. In a clad chase here, a replacement cap or spark arrestor should be black. Local code can ask for more, so ask who checked.
What do white powder, rust streaks and flaking brick faces mean?
White powder is efflorescence, salts left when moisture moves through brick and evaporates, and BIA says efflorescence that keeps returning means water is still getting in. Rust streaks under a window head point at the steel lintel. Flaking faces are spalling, which General Shale ties to repeated freezing of saturated brick. Painting or sealing over them cures nothing; BIA advises correcting deficiencies before any coating.
Can 1970s to 1990s brick veneer simply be repointed?
Sometimes. BIA's triggers are mortar eroded more than a quarter inch, crumbling mortar, voids, hairline cracks or cracks between brick and mortar, and it suggests Type N, O or K mortar and a sample panel. It also warns that a grinder on head joints can damage the brick. If the wall leaks because of flashing, lintels or ties, repointing treats the symptom.
I own a townhome or condo in Vernon Hills. Who repairs the brick?
That depends on your declaration and association rules, which we have not seen. In the Census estimate 2,536 Vernon Hills units are single-family attached and 3,060 are in buildings of five or more, and some may sit under an association. The village permit checklist asks for HOA approval where one applies. Ask the board who is responsible for exterior masonry, and bring any inspection findings.
