Stone masonry is one of the world’s oldest building techniques. Masons have constructed some of the most impressive and elaborate architecture across the globe for centuries. However, even the work of an extremely skilled builder will still require occasional repair and restoration efforts to remain safe and viable. One of the most widely used techniques in modern masonry restoration in Wilmington, DE is known as re-pointing.
Re-pointing is a process in which a restoration specialist removes any deteriorated mortar from wall joints, and replaces it with new mortar. It’s important to complete this process prior to serious deterioration occurring. It’s also important to find an experienced contractor, such as those employed by Mara Restoration, as improperly completed re-pointing can actually cause additional damage.
There are a few ways to tell that re-pointing and other forms of masonry restoration in Wilmington, DE will soon be necessary before it is too late. One easy to recognize symptom of deterioration is cracked, or even missing, mortar between the joints. Any cracks will allow water an inlet to penetrate the wall, potentially causing serious damage when winter comes and it begins to freeze and thaw. Additionally, water getting into the joints causes a process known as efflorescence, in which the water-soluble salts within and on the surface of masonry work crystallize and contribute to even more rapid deterioration.
One common reason to have a wall or structure re-pointed is previous inadequate repair work. If the mortar used was too hard, it will stick out from the wall’s surface, creating an unattractive and inconsistent appearance. This can also lead to deterioration in other areas of the wall. The mortar used for repairs must be matched appropriately to the original mortar, which often proves to be a challenge for those without sufficient experience.
In historic buildings, matching the color and texture of the original mortar is particularly important. Less than professional masonry repairs will not only stand out like a sore thumb, but they may also cause irreparable damage, as the original materials used to construct the wall will most likely not be available to create a matching patch. It cannot be stressed enough that only a licensed professional should be entrusted with historical buildings.
