I know i am late but for future people reading through this should also consider automatic pool covers if you are looking for all year round safety.  The safety covers mentioned above are more for winterization or covering your pool during a time you dont want to use it.  They take time to install and are not an in season friendly option.  

automatic safety covers like coverpools are a key switch operated safety cover that covers and uncovers the pool in a matter of seconds.  When installed by a professionaly trained installed they can easily hold the weight of multiple adults and children.

I work with a lot of pool guys and also have a pool   On an anual contract you should expect to pay 2500-3500 to open, close and maintain your pool for the year. 

There are so many variables that will affect the overall costs of maintenance, chemicals, etc.  For starters, where you live makes a difference in how many months of the year that the pool will be operational and energy costs will vary from region to region.  

Another factor to consider is if you will rely on a pool services company to open and close your pool annually or if you will be doing some of these services on your own.  The cost to open and close a pool is determined by the size of the pool.  In addition, many companies (including ours) offer discounts on pool chemicals if purchased in February, March, or April.  This can save customers a lot of money.  

In general, figure your annual costs could range from $500 to $4,000 depending on what services, i.e., openings/closings, weekly maintenance, repair, chemicals, etc. that will be used compared to how much you plan on doing yourself.

Your pool builder should be able to give you a fairly accurate assessment when you get to the final design stage.

In the Houston Metro Area our customers expierience an annual cost of about 1,500-2,000,  this includes electrical, gas, and chemicals.  

These numbers represent an average sized pool, average spa usage, and properly maintained pool chemistry.

I do not work on pools, but used to have an in ground with vinyl liner in my home.  The first thing that came to mind when I started reading your post was switch to salt water.  Then I read that you mentioned that!  I don't know all the benefits why you should, but I thought the largest were that they are easier to maintain and don't require as much chemical as a chlorinated pool.  Some people I know say that they are much more enjoyable to swim in as well.  

Great questions. Answer will depend on your overall renovation budget and projected use of the pool.

You may wish to track your use and cost (maintanence, electric, water, personal hours cleaning, chemicals)  for one year to help assist you with a renovation option.

Galloway Roofing & Siding does not work on Pools.

Start by deciding if you'd like to have an above ground pool or below ground pool. There's gotta be a significant cost factor there I'd think.
