If you have a new swimming pool or have purchased a home with a one, and wish to hire a company to maintain it for you - how do you find such a company? If you had it installed by a professional company, then you can inquire about whether they also do maintenance.
Get a quote on maintenance rates from this company and compare it to the rates of other local pool companies.
Keep in mind that just because the company that installed your pool did an excellent job and were competitively-priced, that does not necessarily mean they will be equally good or well-priced when it comes to regular maintenance.
Otherwise, you could ask neighbors with pools about the companies they use for maintenance.
Ask more than one neighbor and see if the same company is recommended more than once.
If one of these neighbors has a scheduled pool maintenance coming up soon, it doesn't hurt to ask if you can "sit in" on the pool maintenance and meet the company representative doing the work.
If you happen to be the only person on your block with a pool, or are in a brand-new subdivision with no other completed houses, or are in a rural area with the nearest neighbor being miles away, then it's time to get on the internet and check the yellow pages.
First, find the nearest companies through the yellow pages then do a web search for them and check reviews.
But regardless, make sure you do have proper maintenance done on your pool so that it stays in working order for many years to come!
