Chimney Leak Detection: Flashing, Crowns, and Flue Liners
Water leaks in your chimney can cause serious damage if left unchecked. Most leaks start in three common areas: damaged flashing where the chimney meets your roof, cracked chimney crowns at the top, or deteriorated flue liners inside. Our team knows exactly where to look and how to fix each problem properly. We inspect every chimney thoroughly before recommending repairs, so you only pay for work you actually need. Flashing repairs require careful waterproofing techniques to seal the gaps between brick and roofing materials. Crown repairs involve rebuilding the concrete cap that protects your chimney from rain and snow. Flue liner work ensures smoke vents safely while keeping water out. Our chimney repair services address all these issues quickly and affordably. Do not wait until water stains appear on your ceiling or walls. Contact us today for a complete chimney inspection that protects your home.

Safety First: Repairing Loose Steps and Uneven Walkways
Loose brick steps and uneven walkways are more than just an eyesore. They create serious trip hazards for your family, guests, and delivery people. Elderly family members and young children are especially vulnerable to falls on damaged masonry surfaces. We take these safety concerns seriously and prioritize repairs that prevent accidents. Our team rebuilds settled steps, re-levels sunken walkways, and stabilizes loose bricks before someone gets hurt. We address the underlying causes like poor drainage, soil erosion, or failing foundations that led to the problem. Our step repair services restore both safety and beauty to your property entrances. Every repair includes proper base preparation and drainage solutions to prevent future settling. Do not wait for an accident to happen. Contact us today for a safety inspection of your outdoor masonry surfaces. Let us fix these hazards before they cause injuries or liability issues.


The Dangers of Water Intrusion: Why Prompt Tuckpointing Matters
Water is the number one enemy of masonry structures. When mortar joints deteriorate, water seeps behind your brick and causes expensive damage you cannot see. This moisture freezes in winter, expanding and cracking the brick from the inside out. Wet masonry also promotes mold growth, wood rot, and insulation damage inside your walls. These problems start small but grow worse every year you delay repairs. Tuckpointing replaces old, crumbling mortar with fresh, waterproof joints that keep moisture out. This preventive maintenance costs far less than repairing extensive water damage later. Our skilled masons match the original mortar color perfectly so repairs blend seamlessly with existing masonry. We also seal cracks and gaps that allow water entry. Regular tuckpointing extends the life of your brick by decades and protects your investment. Do not ignore deteriorating mortar joints. The longer you wait, the more damage occurs and the higher your repair costs climb.

Structural Retaining Wall Codes in Ontario, CA: What You Need to Know
Building a retaining wall in Ontario requires more than just stacking blocks or stones. Local building codes have specific requirements for height, drainage, structural support, and setbacks from property lines. Walls over a certain height need engineering plans and city permits before construction begins. Our team understands these regulations completely and handles all the paperwork for you. We design retaining walls that meet code requirements while matching your property's aesthetic. Proper drainage behind the wall prevents hydrostatic pressure that causes failures and collapses. We install drainage systems, geotextile fabric, and compacted base materials according to engineering specifications. Our retaining wall services ensure structural integrity and long-term performance. Trying to build without permits can result in fines, removal orders, and liability if the wall fails. Let us build your retaining wall the right way from the start, with proper permits and professional engineering when needed.
