No matter what type of swimming pool you have it will eventually require basic maintenance and repair to keep it safe and functional. Your approach will depend on how big or how small the damage your pool has, if it is big you will have to ask for assistance from professionals, but if the damage is small then you can do it on your own using repair kits sold by swimming pool supply stores. First thing you should do before doing some repairs is to know what type of pool you own.
When trying to repair pools made of concrete and gunite you will be needing plaster to cover up small cracks and holes as they tend to appear when the pools age. Specifically concrete and gunite pools get hollow spots, chippings, cracks, and wear spots which cause the gunite located below the plaster to become visible. Fear not because these types of problems can be easily repaired with the use of kits that are readily available.
If you own a fiberglass pool you would probably notice that they often get bubbles or blisters along with the cracks that pop up. To handle these kinds of situations you would have to do some fiberglass pool refinishing or resurfacing using a fiberglass repair kit sold at the swimming pool supply store. You will be able to swim comfortable and safely after repairing but there are consequences such as the color of the fiberglass, which means that evidence of repair will be available due to the color of the old fiberglass and the new one not matching. The only solution for this problem is to resurface your whole pool.
If you own a vinyl pool or a vinyl lined pool it will be much easier for you to fix on your own. The only challenge you will be facing when fixing a vinyl pool is finding the crack, and if you find the crack you can just easily use the vinyl repair kit and you are done. While under water you can still repair the crack or tear of the pool using the vinyl repair kit.
But if the damage is too big to fix on your own you can call a professional to fix the damage but with higher cost. But before you hire a contractor you should do a background check on the contractor and the company he or she is working for and also ask for an estimate of how long the project will take to complete. One strategy you can do to save money when hiring a contractor is to do it when the demand for such services is low for example during winter. Problems like huge cracks, plumbing issues and filtration system failure are best left handled by professionals.
