A well-built and well-maintained pool will last for years. But after a while,
even the best care will not prevent a pool from showing signs of age.
An old pool, or even a poorly maintained pool, is not a lost
investment. A few repairs or may be all that is needed. If major work is called
for, you'll probably want a pool contractor to do it for you.
Repairing Cracks
In-ground cement or gunite pool walls may crack from earth movements
under the shell or around the deck. Hairline cracks are easily repaired with a
small amount of plaster, caulking compound or epoxy putty once you lower the
water below the damaged area.
Check the extent of the crack. Large cracks may indicate a serious
problem, possibly from soil movement or poor drainage. If a large crack should
appear, it may be necessary to drain the pool and be sure to consult a
certified pool professional.
Replastering Concrete Pools
For best appearance, concrete pools should be replastered about every
10 to 15 years or repainted every 3 to 5 years. This is due to daily contact
with pool chemicals and changing water temperatures, which often cause flaking
or chipping.
Slight damage can be buffed and patched or painted over. In areas
where mineral content or water hardness is excessive, it may be necessary to
replaster sooner.
Mending a Vinyl Liner
Most tears or punctures are easily repaired by the pool owner. Some vinyl
companies even offer underwater patching kits, so you don't need to drain the
pool for repairs. Tears longer than two to three inches are more serious. If
the repair is very costly to fix, it may be better to replace rather than
repair the liner.
Repairing Fiberglass Surfaces
Although this material is strong and durable, over time the smooth
finish may fade, chip or discolor. If this occurs, your warranty may cover the
cost. If the damage is small, patching the area may be all that is necessary.
For larger areas, you may have to recoat the entire pool. A simple coat of
epoxy paint may improve the appearance of an older fiberglass shell.
Be sure to always follow manufacturers' recommended procedures.
Tile Care
Tile trim along the inner edge of a pool can be very sensitive to shifts in the
soil, and it can crack or pop off. Stronger adhesive can be used to re-lay the
tile. If there is actual structural damage, some excavation and rebuilding may
be needed along the outer area of the pool.
