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. Knowing what type of pool you have is the first step in repairing it.
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. The gunite below the plaster will begin to show through due to the cracks, chippings, wear spots, and hollow spots that pop up when the pool ages. You will be able to fix these problems by yourself with the help of the readily available repair kits.
If you own a fiberglass pool you would probably notice that they often get bubbles or blisters along with the cracks that pop up. You can easily do this using a fiberglass repair kit that can be purchased at any boat and marine 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. If you want to fix the aesthetic as well is to have your entire pool resurfaced in order for the color of the old and new fiberglass to match.
Vinyl pools or vinyl lined pools are considered the easiest pools to fix without the help of a professional. Vinyl pools are quick and easy to repair that you only need to find the crack and use the vinyl repair kit which is easy to use. What is special about vinyl repair kits is that you can use it to fix the tear or crack while under water, but it would still be a good option to drain your pool first before doing the fixing.
On the other hand you can hire a contractor to fix the damage for you if the damage is beyond your capabilities even with the help of the repair kits. Before you hire a professional to fix your pool you should consider knowing about the contractor and how long it will take for the project to finish. It would really help you save a lot of money if you hire the pool repair contractor a few weeks before swimming pool season because during that time the workload for such professionals is very low. Problems like huge cracks, plumbing issues and filtration system failure are best left handled by professionals.
