Masonry Waterproofing in Orland Park, IL — Sealing That Actually Protects Brick

Most of what gets sold as "brick waterproofing" in the southwest suburbs is a sprayed-on afterthought. Someone coats a wall that already has open joints and cracked brick, the homeowner feels protected, and two winters later the face of the brick is flaking off worse than before — because the coating trapped the water instead of keeping it out.

Paul Lally's Masonry Inc. provides masonry waterproofing and brick sealing in Orland Park, IL — finding and repairing the actual water path first, then applying a breathable penetrating repellent that keeps driving rain out of the masonry while letting the wall dry. Family-owned, serving Chicagoland since 1988, insured. Free on-site estimate: (708) 448-8866.

The rule that decides whether sealing helps or hurts

Repair first. Seal second. Never the other way around.

A penetrating water repellent is designed to handle one thing: wind-driven rain hitting sound masonry. It cannot bridge an open mortar joint, a cracked brick, a failed sill, a rusted lintel, or a gap at a window. Water entering through any of those goes past a sealer as if it were not there — and then the sealed face slows down how fast the wall can dry back out.

So the honest sequence on an Orland Park home is:

1. Diagnose the water path — where is it actually getting in?
2. Repair it — tuckpointing, brick repair, sills, lintels, caulk joints, flashing
3. Let new mortar cure
4. Then apply a breathable repellent to the sound wall

Do it in that order and the sealer earns its keep for years. Do it backwards and you have paid to lock the problem inside.

Breathable repellent vs. film-forming coating

| | Penetrating repellent (silane/siloxane) | Film-forming coating (acrylic, "wet look") | |---|---|---| | Where it sits | Soaks into the masonry pores | Sits on the surface as a film | | Water | Repels liquid water | Blocks liquid water | | Vapor | Lets the wall breathe and dry | Traps moisture inside | | Appearance | No gloss, no color change | Glossy, darkens brick, can cloud | | Failure mode | Gradually wears and is reapplied | Peels, blisters, and spalls the brick face |

Brick walls are not meant to be airtight. They are meant to shed water and dry out. Anything that stops them from drying is working against the wall, and in Chicagoland's freeze-thaw climate trapped moisture is exactly what pops brick faces off. That is why we use penetrating silane and siloxane repellents chosen for the substrate — dense modern face brick, softer older brick, and limestone or cast stone trim do not all take the same product.

Why Orland Park walls need it

Orland Park's housing stock is largely 1970s through 2000s brick-veneer subdivisions, plus the older brick and stone around Old Orland, and a substantial commercial and multi-family stretch along the LaGrange Road and 143rd Street corridors.

Brick veneer is a drainage wall: a single wythe of brick with an air cavity behind it, flashing at the base and over openings, and weep holes to let water back out. It is designed to get wet and drain. That design assumes the mortar joints, the flashing, the sealant joints, and the weeps are all doing their jobs — and after twenty-five to fifty winters, on a lot of Orland Park homes, several of them are not.

Add the local exposure. Open subdivision lots and the ground around Centennial Park and the Lake Sedgewick area give west and south elevations very little shelter from driving rain. Wide-open backyards on newer streets do the same. Those elevations absorb the most water, go through the most freeze-thaw cycles, and show efflorescence and spalling long before the protected sides do.

Our waterproofing process

1. Walk the whole envelope. We look at joints, brick faces, sills, lintels, chimney, caulk lines, weeps, grade, gutters, and downspouts — because water rarely enters where it shows up inside.
2. Repair the entry points. Repointing, brick replacement, sill and lintel work, and sealant joints are completed first.
3. Let the mortar cure. New mortar needs curing time before anything is applied over it.
4. Clean and prepare. Surfaces are cleaned appropriately — never sandblasted, never blasted with high pressure, both of which permanently open up the masonry and make the water problem worse.
5. Test-apply. A trial area confirms absorption rate, coverage, and that there is no unwanted change in appearance.
6. Apply the repellent properly. Low-pressure, flood-coat application with correct overlap and coverage rate, masking windows, trim, and plantings. Under-applying is the most common failure — the material has to saturate, not mist.

What drives the cost of waterproofing in Orland Park

• Square footage of wall to be treated
• Height and access — a ranch elevation versus a two-story or a chimney needing staging
• Masonry porosity — thirsty older brick takes considerably more material than dense modern face brick
• Repairs required first — usually the largest part of the job on an older home
• Substrate mix — brick, limestone trim, and cast stone may need different products
• Surface prep and cleaning needed before application
