Church & Institutional Masonry Restoration in Naperville, IL — Written for the Building Committee

A congregation buys masonry differently than a landlord does, and almost nothing written for this market accounts for it.

The money is raised rather than budgeted. The decision goes to a building committee, a board, or a council — several people, most of whom do not work in construction, meeting monthly. The building is occupied every weekend and often most weekdays. And the work will very likely be phased across years, because that is how restricted funds and capital campaigns actually arrive.

What a masonry contractor should actually be telling a church board

There is a lot of material aimed at congregations that promises to restore your building "from floor to ceiling" — steeples, stained glass, altars, roofing, electrical, plumbing — and never once names a mortar type, explains what tuckpointing is, or says how a committee should sequence and fund the work.

That is general contracting with a church label on it. It is a legitimate business, but it is not a masonry answer, and it leaves a board unable to evaluate the single largest line in most sanctuary restoration budgets.

Here is the masonry answer.

The five places institutional buildings actually fail

Mortar joints on the weather elevations. South and west walls take driving rain and the strongest wet-dry cycling and run years ahead of the north and east on the same building. On a masonry sanctuary a hundred years into its life, the joints are the consumable — they were designed to be, and they are due.

Towers, steeples, and belfries. The most exposed masonry on the property, weathered on every face with no roof over it, and standing directly above the entrance most people use. Louvred belfry openings admit driving rain into the core of the wall by design, which is why tower masonry is almost always in worse condition than the nave below it.

Limestone. Sills, water tables, hood moulds, tracery surrounds, buttress caps, and entry surrounds. Limestone delaminates along its bedding planes when water freezes inside it, and once a sill loses its pitch or its drip edge it starts feeding the wall beneath it. Our page on limestone and sill repair covers the mechanism.

Parapets and roof edges on the education wing, the fellowship hall, and the flat-roofed additions almost every congregation has built at some point. Weathered on three surfaces with no heated space behind them, and directly over walkways.

The junction between the original building and its additions. Cold joints where 1920s masonry meets a 1958 wing meets a 1994 addition. Three different mortars, three different movement rates, and a seam that opens.

Naperville, specifically

Naperville gives this work an unusually wide range, because the city's institutional building stock spans well over a century.

The older congregations near downtown — around the Jefferson and Main corridor and the streets off the Riverwalk — sit in genuinely historic fabric, with soft brick, lime-rich mortar, and cut limestone detail. That masonry is not fragile; it has stood for a hundred years. It is, however, intolerant of hard modern mortar and aggressive cleaning, both of which do permanent damage. Mortar softer than the surrounding units is not a preference here, it is the requirement.

The post-war parish and school buildings through the older neighbourhoods — brick and block, steel lintels now at the end of their service life, cast stone trim, and flat-roofed wings with parapets.

The large campuses out along Route 59, 75th Street, and the newer corridors — 1980s-onward masonry veneer over frame or block, where the issues are sealant renewal, expansion joints, shelf angles, weep holes, and flashing rather than wholesale repointing.

Schools and municipal buildings across DuPage, where the funding source rather than the building determines the procurement rules.

Three different eras, three different repair vocabularies, frequently on the same campus.

How we scope work for a committee

The deliverable is not a number. It is a document your board can actually use.

1. A free on-site assessment, elevation by elevation, with photographs.
2. A written scope with square footages, the repoint-versus-rebuild split, access method, materials, and — importantly — stated exclusions, so the committee is not surprised later.
3. A defensible priority order: overhead and structural first, active water entry second, deterioration third, appearance last. If money is short, this is what tells you where it should go.
4. A phasing proposal across two, three, or five years, grouped by access rather than by category — because the expensive part of tower work is getting up there, and doing two tower items in one mobilisation costs meaningfully less than doing them in different campaigns.
5. A schedule written around the building's calendar — weekend services, weekday programs, school hours, funerals, weddings, and the seasons when mortar can actually cure.
6. COI, W-9, and lien waivers provided on request, before work begins.

Materials and technique

Mortar matched to the existing masonry in type, hardness, colour, sand, and joint profile — with softness relative to the surrounding units treated as the governing constraint on historic fabric. Type N where the wall calls for it, Type S where it genuinely does. Salvaged brick reused wherever it is sound, and replacements matched in size, colour and texture. Limestone repaired in place, patched with stone-appropriate repair mortar, or cut out and repaired with a matched Dutchman insert where the unit is largely sound. Through-wall flashing and coping detailed to move water back out of the wall rather than trapping it.

No sandblasting, and no high-pressure washing. Both strip the weather-resistant outer skin from historic brick and limestone, and the damage does not grow back.

What drives the cost

Elevation area and height. Access — ground-level walls, staging, lifts, and tower work are four different cost structures. The ratio of repointing to rebuilding. Limestone and decorative unit scope. Parapet, coping and flashing work. Overhead protection where the public passes beneath. Whether the project is phased and therefore mobilised more than once. Whether prevailing wage applies. Weather windows, since mortar needs workable temperatures to cure properly.
