Once the mortar is replaced, the joints are tooled to match the rest of the structure - some joints are concave, flat, cut, weeping, and some reveal exposed aggregate. Proper tuck-pointing can take years to learn it is not easily mastered. It is important to blend compatible materials to create a uniform restoration job. Poor tuck-pointing can actually cause more harm than good to a masonry structure and accelerate its deterioration. Is the mortar soft or hard? Is it lime putty or Type S cement? Is the aggregate large or fine? Would hydrated or hydraulic lime be best suited for the project? Modern day mortars are very hard compared to the lime putty mixes from a hundred years ago. Matching mortar includes taking into account the age of the existing mortar, the mortar type and mix, the aggregate used, the base color of the cement, and the correct tints to achieve the right match.Īn often overlooked aspect of tuck-pointing is the age and composition of the structure's mortar. Once the area needing repair is identified, a professional mason carefully removes the mortar between the brickwork to a depth of ¾ to 1" - then, properly-matched mortar is formulated to replace the old mortar. What do you do if there are cracks in the mortar between your bricks? Or if parts of the mortar have been washed out by rain or snow? That area of your masonry wall needs to be tuck-pointed. Why settle for a meh job? Let us go that extra mile for you and bring your building/home back to life. If only patching is required, we can do that too. Because of modern innovations and technology, we have access to products that allow us to recreate historic features, working from intact samples. These features add unique character to many of our local homes and buildings. Many decorative features on older buildings are no longer produced, such as decorative terra-cotta features, sandstone carvings, ornate arches and ledges, and patterned designs such as egg and dart, and quatrefoils. Tuck-pointing or repointing is often needed when restoring a building or home - shifting and settling, weather, and exposure often play a big role in the deterioration of mortar joints. Sometimes it requires removing/replacing damaged brick/masonry units from the structure. We offer "face-lifts" for homes and buildings - usually including restoration cleaning the envelope of the structure, removing decades of staining, pollution, and grime from the façade. Masonry restoration can take many forms - it can involve structural repairs and/or cosmetic work. Have a masonry repair project? Let us know how we can help! It is important to understand the original mix used on a structure, then recreate a matching mix for masonry repairs. New, rock-hard, mortars can actually cause more harm than good when applied incorrectly to older homes and buildings made with softer mortar. The type of mortar used is important, especially when working on old/historic masonry. Finesse and proficient extraction, using old and modern techniques, is key to maintaining the integrity of the structure.Ī well-matched mortar helps blend the newly replaced masonry units into the surrounding structure. When extracting the units, there is danger of damaging the surrounding areas. If masonry units are cracked, spalling, or deteriorated and require replacement, it is important to select the correct replacement materials: size, color, style and finish, and a properly matched mortar each impact the final masonry repair product. These masonry issues can be examined by qualified professionals to determine the best course of action. Many times cracks in masonry structures are exterior signs of internal/foundational issues. Many factors can damage masonry units: weather, water, exposure, freeze/thaw cycle, poor repairs, foundational issues, and improper drainage. Matching mortars, not just color, but using the right mortar mix - appropriate to the age of the structure - is key for the longevity of the structure and preservation of the masonry unit(s). Using matching/complementary materials and the right blend of old and new make the repairs flow aesthetically. A well-executed repair should not stand out when it is complete. Proper masonry repair is an art form - it can take years to master.
