Chimney Repair St. Louis Park MN
Prior to looking at chimney repairs, it is important to look at the structural form of the chimney as this is the foundation of the preliminary procedures. The brick and mortar should not allow rain or other elements to infiltrate the chimney’s composite structure.
Deterioration to chimneys may be brought on by a number of factors. Nevertheless, the scope and size of repairs is most frequently 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 due to deteriorating mortar, excess moisture within the chimney, or a chimney fire will weaken clay tile liners and the brick, it is vital 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 excessive freeze/thaw cycle, adds even more weight to the demand for frequent inspections.
Expert repairs are needed when you feel that the scope of the deterioration is over and above what you can easily 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 service 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 raises considerably. This often leads to rapid expansion damage during the freeze/thaw.
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.
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 noticeably causing an observable (sometimes hazardous) lean as time goes by. Remarkably, a chimney that leans due to this process will usually 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.
Regardless of many essential preventative measures, if you find any cracks, signs of degeneration, crumbling mortar in the chimney, it is time to get reach out to our professionals here at Dayco General for a chimney inspection to verify the well-being of your home. Ignoring masonry chimney issues may possibly be downright costly and dangerous for your family.
