Keep your home safe with professional chimney repair and rebuilding from experienced masonry contractors.

Why Chimney Safety Cannot Wait
Your chimney does critical work protecting your home from smoke, carbon monoxide, and fire hazards. When it starts to fail, the risks go beyond just cosmetic damage. A deteriorating chimney can allow deadly carbon monoxide to leak into your home, create fire hazards from cracked flue liners, or cause water damage that spreads to your ceilings and walls.
Here in McAllen, TX, chimneys face unique challenges. While we do not deal with snow and ice like northern climates, our intense sun, heavy rains, and temperature swings still cause significant wear and tear. The heat causes expansion and contraction that can crack mortar and bricks over time. Rain can penetrate through tiny gaps and cause internal damage you cannot see from the ground.
Warning Signs Your Chimney Needs Attention
- •Crumbling or missing mortar between the bricks
- •White staining on the exterior indicating water damage
- •Damaged or missing chimney crown at the top
- •Rusted or damaged chimney cap or flashing
- •Visible cracks in the chimney structure or leaning
- •Water stains on the ceiling near the chimney
If you notice any of these warning signs, call MAC McAllen Masonry for a thorough inspection. We climb up and examine every part of your chimney structure, from the foundation to the cap, and give you an honest assessment of what needs repair or replacement.
Chimney Repair or Complete Rebuild
The decision between repairing and rebuilding a chimney depends on the extent and location of the damage. Minor issues like deteriorated mortar joints or a damaged chimney crown can usually be repaired without a full rebuild. However, structural problems like significant leaning, large cracks through multiple bricks, or extensive water damage throughout the chimney often make rebuilding the safer and more cost-effective long-term solution.
When Repair Makes Sense
Chimney repair works well when the damage is localized and the overall structure remains sound. Common repairs include repointing mortar joints where the mortar has weathered away, replacing damaged bricks in specific sections, fixing or replacing the chimney crown, repairing flashing to prevent water intrusion, and installing or replacing chimney caps to keep out rain and animals.
These targeted repairs can extend your chimney's life by many years when caught early. We use high-quality materials that match your existing chimney and follow proper installation techniques to ensure lasting results. The key is addressing problems before they spread and cause more extensive damage.
When Rebuilding Is Necessary
Sometimes a chimney has deteriorated beyond the point where repairs make financial or safety sense. A complete rebuild involves taking down the damaged portion and reconstructing it properly from the ground up. This is necessary when the chimney is leaning significantly, when there are major structural cracks affecting stability, if the flue liner is damaged throughout, or when water damage has compromised the entire structure.
While rebuilding costs more upfront than repair, it gives you a chimney that meets current safety codes and will last for decades. We handle the entire process from obtaining permits to final inspection, and we build your new chimney to exceed industry standards. You get peace of mind knowing your chimney is safe and built right.

Chimney Crown Repair and Replacement
The chimney crown sits at the very top of your chimney and acts as the first line of defense against water. A properly constructed crown sheds water away from the flue and protects the masonry below. When crowns crack or deteriorate, water seeps into your chimney and causes extensive damage over time. We rebuild crowns using durable materials with the proper slope and overhang to provide maximum protection.
Flashing Repair and Installation
Flashing creates a waterproof seal where your chimney meets your roof. This is one of the most common spots for leaks to develop. We install new flashing using quality materials and proper techniques that ensure a watertight seal. Whether you need step flashing replaced, counter flashing repaired, or a complete flashing system installed, we have the roofing and masonry knowledge to do it right.
Structural Chimney Rebuilding
For chimneys that need complete reconstruction, we provide full rebuilding services. This includes demolishing the unsafe portions, installing proper reinforcement and flue liners, building the chimney structure with carefully matched bricks, installing a new crown and cap, and ensuring everything meets current building codes. We coordinate with roofing work when necessary and handle all inspections so you do not have to worry about the details.
