Masonry Waterproofing in Chicago Ridge, IL — Brick Sealing

Masonry waterproofing in Chicago Ridge, IL — done in the right order

Sealing brick only works when the masonry underneath is sound — and that is where most waterproofing goes wrong. Paul Lally's Masonry waterproofs brick and masonry for Chicago Ridge homeowners the right way: we repair the failing mortar joints first, then apply a breathable penetrating sealer that keeps water out without trapping moisture inside the wall. Family-owned and serving Chicagoland since 1988, licensed, bonded, and insured. Free on-site estimates: (708) 448-8866.

What masonry waterproofing really means

Waterproofing brick is not painting a coating over the wall and calling it done. On a brick home, water mostly gets in through the mortar joints — not the face of the brick — so real protection is a two-part job:

• Repair first. Repoint open, cracked, or sandy mortar joints and replace any spalled brick so the wall is watertight on its own.
• Seal second. Apply a breathable, penetrating water repellent that soaks into the masonry and lets it shed rain while still allowing the wall to dry from the inside.

That order matters. A sealer is the finishing step that protects sound masonry — it is not a substitute for fixing what's already failing.

Signs your Chicago Ridge masonry needs attention

• White, chalky staining (efflorescence) on the brick — a clear sign water is moving through the wall.
• Damp spots or water stains on interior walls or in the basement near brick.
• Open, cracked, or crumbling mortar joints that let water straight in.
• Spalling brick — faces flaking, popping, or pitting after freeze-thaw winters.
• Darkened, saturated brick that stays wet long after the rain stops.
• Peeling paint or a flaking old coating on a previously "waterproofed" wall.

Why waiting lets the damage spread

Water is the engine behind almost every masonry failure. Once it gets into open joints, Chicago Ridge's freeze-thaw cycles take over: the water freezes, expands, and pries the masonry apart — spalling brick faces and widening the joints a little more each winter. A wall that only needed repointing and a breathable sealer this year can need brick replacement or rebuilding later. Sealing at the right time, on sound masonry, is the cheapest insurance you can buy for a brick home.

Our waterproofing process

1. Free inspection. We find where water is actually getting in — joints, cracked brick, a failed old coating, or flashing — instead of just coating over the symptom.
2. Repair the masonry. We repoint failing joints with color- and type-matched mortar and replace any spalled brick so the wall is watertight first.
3. Let it cure. Fresh mortar needs to set before anything goes over it.
4. Apply a breathable sealer. We use a penetrating water repellent that lets the wall breathe — never a film-forming coating that traps moisture.
5. Protect the details. We mask windows, trim, and landscaping, and leave the site clean.

Materials we use

We seal with breathable, penetrating water repellents that bond into the masonry rather than sitting on top of it — the kind of product that repels rain while still letting trapped moisture escape. For the repairs underneath, we match mortar by type and color (Type N or S as the wall calls for) and match replacement brick by size, color, and texture. We avoid waterproof paints and heavy film coatings on brick, because in a freeze-thaw climate they trap water and cause the very spalling they're supposed to prevent.

What drives the cost of waterproofing

We never publish a flat price, because every wall is different. What moves the number:

• How much repair comes first — sealing a sound wall is far simpler than repointing failing joints and replacing brick before sealing.
• Square footage and height — more wall and higher elevations need more material and setup.
• Access — tight side yards, landscaping, and multi-story walls add work.
• Condition — efflorescence, old failed coatings, and saturated masonry take extra prep.

Local context: brick homes in Chicago Ridge

Chicago Ridge sits in the heart of Cook County's southwest suburbs, where brick bungalows, ranches, and two-stories take the full force of Midwest weather — wind-driven rain off the prairie and hard freeze-thaw swings all winter. Those swings are exactly what drive water through tired mortar joints and spall unprotected brick. Sealing here is not cosmetic; it's how you keep a brick wall watertight through another Chicago Ridge winter. The key is doing it in the right order and with a breathable product — which is how we've protected Chicagoland masonry since 1988.
