Masonry Repair Houston, TX

Small problems cost far less to fix than to ignore. Open joints let water into the wall, and that water carries salts, feeds algae, and works on the core behind the brick or stone. Catch it at the joint stage and you repoint. Wait, and you may be rebuilding.

• Mortar joints that are recessed, sandy, or crumble when scraped with a key
• Stair-step cracks along mortar joints, or cracks splitting bricks and stones
• Loose, rocking, or cracked caps on walls and columns
• White, powdery deposits on brick or stone, known as efflorescence
• Brick faces flaking or popping off, known as spalling
• Dark wet bands at the base of walls, or water seeping through planter walls
• Gaps opening between a feature and the patio or house

Settlement cracks are the most common structural issue. Clay under a footingFootingThe widened base at the bottom of a wall, column or structure that spreads its load into the ground. dries and shrinks in a long summer, swells in a wet spring, and the masonry above rides along. Stair-step cracks through mortar joints usually mean one end of a wall has moved relative to the other. A crack that is wider at the top than the bottom, or that keeps growing, points to a footing problem that repointing alone will not cure.

Water is the other driver. Downspouts dumping against a garden wall, sprinkler heads spraying brick every morning, flat caps that let rain run down the face, and planters with no liner all keep masonry wet. Wet masonry grows algae under shade trees, pulls salts to the surface, and loses mortar faster. Tropical storm rain driven sideways finds every open joint.

Each repair is matched to the masonry in front of us. The goal is a repair that blends in and lasts, without making the wall harder or less breathable than the original.

• Repointing: raking or grinding out failed mortar to a depth of about two to two and a half times the joint width, then packing new mortar in layers and tooling it to match
• Brick and stone replacement: cutting out cracked or spalled units and setting matched replacements
• Settlement crack repair: diagnosing movement, correcting drainage, and repairing or rebuilding affected sections
• Cap resetting: lifting loose caps, re-bedding them, and adding a drip edge where possible
• Leak repair: tracing water entry at caps, joints, planters, and kitchen counters and closing the path
• Efflorescence and stain cleaning with methods matched to the material
• Water-repellent sealing with breathable penetrating sealers

Repointing done wrong does more harm than leaving joints alone. New mortar has to be softer and more permeable than the brick or stone around it, so that future movement and moisture work through the joint, which is easy to repoint again, instead of through the brick. Older brick laid in lime-rich mortar should be repointed with a compatible lime-based mix, not a hard Portland cement mix that can crack and chip the brick edges.

We also match the look: sand color, joint width, and tooling profile. A concave or V joint sheds water better than a raked or flush joint. On walls that are mostly sound, we repoint the failed areas. When joints are failing everywhere, full repointing gives a more uniform result.

Efflorescence is salt carried to the surface by water moving through masonry. On new work it often fades on its own in the first months. Persistent blooms mean water is still getting in, so we find the source first. Cleaning starts with dry brushing, then, if needed, a masonry cleaner suited to the material, applied to a pre-wetted wall and rinsed thoroughly. We avoid high-pressure washing, which cuts into joints and drives water deeper into the wall.

Sealing comes last, after repairs and cleaning. For vertical brick and stone we use breathable penetrating water repellents, typically silane or siloxane products, which cut water absorption while letting vapor escape. Film-forming acrylic coatings can trap moisture behind the face in our humidity and then peel or cloud. Horizontal surfaces such as brick patios may suit different products; see paver sealing.

Repair costs depend on scope and on what is causing the damage. Fixing the cause, such as moving a downspout, is often part of the job. Our ballpark price tool is a starting point, and a site visit tells us what is really going on.

• Linear feet of joints to repoint and how deep they have failed
• Number of units to replace and how hard they are to match
• Height of the work and whether scaffolding is needed
• Whether a footing has moved and needs correction
• Area to be cleaned and sealed
• Related drainage or irrigation fixes

Many repairs pair with a small drainage fix. Downspout rerouting carries roof water away from walls and columns. Irrigation repair adjusts heads that soak brick every day. A wall that leans or bulges because it holds back soil is a job for our retaining wall repair team, and if a slab under the masonry has cracked or dropped, concrete repair may come first.

As a masonry contractor in Houston since 2016, we handle the repair and the water problem behind it with one team. A Home Scout visits before any proposal is written, the proposal is itemized, and the price we quote is the price you pay. We return 72 hours after completion to walk the work with you.
