Chimney Repair Rockford MN
Prior to delving into chimney repairs, it is critical to examine the structural form of the chimney as this is the grounds of the preliminary procedures. The brick and mortar should not allow rain or other elements to seep into the chimney’s composite structure.
Deterioration to chimneys may be brought on by several issues. Nonetheless, the scope and size of repairs is most often a factor of the age of the structure but can also be brought on by harsh weather (falling tree limbs or lightning strikes) or a chimney fire. Problems brought on by deteriorating mortar, excess moisture within the chimney, or a chimney fire will weaken clay tile liners and the brick, it is extremely important that chimneys are inspected from time to time. The Chimney Safety Institute of America recommends yearly chimney inspection. In the Twin Cities Metro area our harsh freeze/thaw cycles adds even more weight to the demand for consistent inspections.
Expert repairs are needed when you feel that the scope of the deterioration is over and above what you can adequately handle. Inspection by our CSIA certified experts will supply you with a report which offers appropriate maintenance procedures.
Swollen bricks or swollen mortar joints can cause the chimney to lean and lose its stability. Masonry swelling results from age and water leaks in the structure. Both brick and mortar are relatively water resistant when they are brand-new, but without the routine maintenance treatment of a waterproofing sealant, this quality is gradually lost in time and toward the end of their life span the moisture absorbency of masonry escalates substantially. This often leads to increasingly rapid expansion damage during our freeze/thaw.
Older brick and mortar that has been through many freeze/thaw cycles, notably on chimneys that have a leaking cap that has allowed water to both the interior and exterior of a wall, can swell considerably causing an easy to see (sometimes unsafe) lean as time goes by. Surprisingly, a chimney that leans due to this process will often tip away from the sun. In the Northern hemisphere, this means an older chimney with severe freeze/thaw expansion damage will lean toward the North because the sunny side will have a broader depth of temperature variation and even more frequent fluctuations in the freeze/thaw phenomena. We have seen tall chimneys that were leaning so precariously that we advised non-occupancy of areas below the hinge point of the chimney until repairs could be made.
Spalled brick is a very common damage found in chimneys.
Missing mortar joints should be properly repointed with new
mortar to minimize further damage to the chimney structure.
