We must have all rockwork, if there are boulders and waterfalls to be done on your pool completed prior to deck. This is also a good time to install any masonry such as barbecues, firepits, benches, and equipment walls. Any gas lines, landscape sprinkler and drip lines, landscape lighting lines etc. that are to be run under the deck should be in before we form for the deck. This is also a good time to review and make sure that your deck that you have planned is on the plan the way you want it. Extra costs may result if you have us form the deck one way and then decide to change it after forming.
