Owning a home that has a swimming pool is really going to make you popular during summer, but with that honor, you have to think about maintenance. The average home owner will be able to do some of the maintenance on their own; the other projects are best done by a professional. Below are steps of what a pool maintenance contractor may do.

Pool Maintenance 101

If you own a pool, then the maintenance is going to be a requirement. A neglected pool is quick to become a frog pond or ponds that are filled with algae, mosquito nests, and other aesthetic and health issues. Fortunately, the right pool maintenance is easy when you have a regular schedule.

  • Skimming – This is the first step to pool maintenance. A skimmer is a mesh net that is attached to a long pole and is used to remove any floating debris like drowned insects and leaves. If it is left alone, debris will clog the filters and sink to the bottom where it can cause stains. You may also notice that debris will cause issues with the circulation system of the pool. Skim the pool every few days. Be sure to remove, dump and then clean the strainer baskets weekly.
  • Vacuuming – A skimmer won’t get everything, so even when you are skimming regularly, the fine particles such as dirt and dust will sink and settle in the bottom of the pool. That is why your pool will need to be vacuumed regularly. There are 2 types of pool vacuums which are manual and automatic. Automatic vacuums will run in the bottom of the pool and suction things up in a random pattern while a manual vacuums attach to a long pole that will let you steer the suction. When you use an automatic vacuum ensure that your passes are overlapping to get all the fine debris. If you have a large pool, vacuum in sections and do it weekly.
  • Brushing – Brushing will keep your pool walls clean. The type of brush you will need will actually depend on the material of your pool walls. A plaster pool will need a stiff bristled brush while vinyl, fiberglass, and tile will need a soft bristled brush. For the stubborn buildup you can use a putty knife, pumice stone or a 50/50 mix of muriatic acid and water but be sure to wear eye protection and gloves. Brush the pool walls weekly before you vacuum. Brushing will loosen up any particles for your vacuum to get.
  • Cleaning Filters – There are 3 types of filters: DE, sand and cartridge. Each type will have unique requirements for cleaning. Sand filters need to be backwashed and treated with a special cleaning chemical. Cartridge filters need to be removed and sprayed down with a garden hose. The DE filters need to be backwashed, but you will need to add more DE to it. DE filters tend to trap smaller particles.
  • Pool Heater Maintenance – The average pool heater can last a few years before it needs to be serviced. Sometimes there can be a build up of calcium or other minerals on the heater tubes, which restrict the operation. Whenever this happens, it is best to hire a professional to take it apart and repair the heater.
  • Water Level – Your pool can lose water from splashing, natural evaporation and people getting in and out of the pool. Check your water level each time you skim the pool and clean the baskets. Water levels shouldn’t fall below the intake tube on the skimmer. This may ruin your pump. When the water level gets low, simply use a water hose to fill it to the right level.
  • Maintaining pH – The pH level of your pool water will determine the alkalinity and acidity. There is a certain level of acidity that needs to be met in the pool. A pH of 7 is best. Any pH lower than 7 is too acidic. Having acidic water may damage the liner of the pool, your skin, and pool equipment. Water that is too alkaline can cloud your water and clog filters and even cause your nose and eyes to burn as well as cause itchy and dry skin. A home testing kit can tell you the pH of your pool. Adding chemicals to neutralize the water is recommended.
  • Shocking the Pool – Organic contaminants like nitrogen and ammonia can build up over time in your pool. These contaminants will interact with the chlorine to create chloramines which cause the chlorine odor that comes from your pool. Just add more chlorine can take care of that. This is called shocking. Some owners will shock their pool weekly while others wait longer. Follow the instructions for your pool to ensure that your adding the right amount to fix your problem.
  • Leak Detection – If you are having to add more water a lot, you could have a leak. Finding the leak is easy. Fill a plastic bucket about ¾ of the way up and mark the water line inside the bucket. Float it in the pool and mark the water line on the outside of the bucket. After a few days compare the water lines. If the amount lost is the same, then its due to evaporation, but if there is a difference then you have a leak. You will need to call a professional for repairs.
  • Winterizing – If you live in an area that freezes, you will need to winterize your pool. This means you have to remove water from the pluming with an air compressor and drain as much water from the heater and filter. Remove the rest of the water with a special antifreeze made for pools. Disconnect the heater, pump, and chemical feeders. Clean and store the chemical feeders. Clean the pool and close skimmer valves and lower the water level to 18 inches below the pool edge. This will allow for freezing expansion without there being pressure on your pool liner. Lastly, shock the pool and cover it to prevent debris from falling in.
  • Reopening – When it is time for swimming season, clear the debris around the pool. Refill your pool to normal levels, open your skimmer valve to get the water circulating. Test your pH level and shock the pool. Turn the pump on and leave it running. Decrease this time by 1 hour every day until the water is balanced and then you can swim.

If you are unable to maintain your pool, hire a pool service. Pool services can handle everything from closing and opening your pool for the seasons to regular treatments. Most pool maintenance services will cost around $75-$100 hourly. Some services could cost extra.

Common Pool Repair Costs

It doesn’t matter how well maintained your pool is, it will need repairs eventually. When this happens, call a professional. Leave the pool repairs to them which keeps repairs from causing major issues.

  • Pump Motor Repair Cost: The most common part of the pool that will need repairs is the pump motor. Besides the cover, the pump will affect your pool.

  • Pool Filter Repair Cost: If you maintain your filter, you won’t have to worry about replacing the cartridges as often. If your filter needs cleaning a lot, it is probably trapping oils which are hard to remove. The right sized cartridge needs cleaned every 3-5 weeks. A new cartridge can cost around $13-$75.
  • Sand Filter Repair Cost: Sand filters come with a pressure gauge. If the pressure is too high, the filter isn’t working right. It can cause failure and cause the tank to rupture. If the pressure is fine, but you have to clean it a lot, then you may need to replace the sand. New sand is rough, which helps to trap particles. Over time, water will make the sand smooth and reduce how it works. Sand is about $12 per bag. Replacing the filter system is around $150-$500+.
  • DE Filter Repair Cost: The DE filters may fail like a sand filter. A failing DE filter will put DE in your pool. A professional will tell you if it is time to replace the valve or O-ring. Your stainless steel tank may also have pinhole leaks. When this happens, the tank needs to be replaced. Replacing a DE filter system is around $625-$725.
  • Pool Leak  Repair Cost: Finding out if you have leak is easy when compared to fixing it. A pool repair technician can find if the leak starts at the filter or in the pool. You can patch a vinyl liner for around $20 with a patch kit or you can hire a professional to do it for $225. Fiberglass liners need to be repaired by a professional for around $300. Gunite or concrete pools needs to be drained, sanded and properly sealed. This can cost around $900-$2000.
  • Heater and Heating Tube Repair Cost: When water goes through the heating tubes and back in to the pool, minerals will buildup and cause blockages. Insects will also crawl around and in the system which can affect how it works. The average cost to repair a pool heater is around $400. If left alone, the pool heater repair can cost around $1300.
