Chimney Repair Eden Prairie MN
Prior to looking at chimney repairs, it is important to evaluate 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 permeate the chimney’s composite structure.
Harm to chimneys may be brought on by a number of factors. Nonetheless, the scope and size of repairs is most normally a factor of the age of the structure but can also be brought on by severe 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 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 harsh freeze/thaw cycles adds even more weight to the requirement for consistent inspections.
Expert repairs are needed when you feel that the scope of the deterioration is above and beyond what you can easily handle. Inspection by our CSIA certified experts will supply you with a report which offers correct 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, particularly on chimneys that have a leaking cap that has allowed water to both the interior and exterior of a wall, can swell considerably causing a detectable (sometimes unsafe) 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 a lot more frequent fluctuations in the freeze/thaw phenomena. We have seen tall chimneys that were leaning so precariously that we strongly recommended 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.
Also, note that unforeseen damage can possibly be caused by pressure washers and sandblasters. High-pressure sprayers and sandblasting can remove a portion of the brick and mortar surface area. Care must be taken if pressure washing becomes required. Steer clear of using a machine that is overpowered for the job or getting too near to the surface of the masonry with the spray tip. Sandblasting should only be undertaken by a knowledgeable specialist.
In spite of many essential preventative measures, if you find any cracks, signs of degeneration, crumbling mortar in the chimney, it is time to get call our professionals here at Dayco General for a chimney inspection to verify the safety and security of your home.
