The great thing about Non-Surgical Spinal Decompression Therapy is that there is no cutting, no anesthesia, and nothing inserted or installed in your spine that has the potential to cause infections. Nothing is wired, pinned, or screwed to the spine itself, and no bone is cut away or transplanted from cadavers.
Bearing in mind these cost factors, the average cost of a professionally-installed lawn irrigation system is $500-$1,000 per zone, or around $2,500 to $5,000 for a typical Â½ acre lot. Note, however, that zones are, proportional to the entire system cost, cheaper to install.
Cost of installing sprinklers declines. According to a recent NFPA research report, fire sprinkler costs have dropped in recent years. âIn 2008, the average cost we found was $1.61 per square foot of installed sprinklers,â Carli says. âIn 2013, the average is $1.35.â She credits mandates, which means more contractors are installing fire sprinklers in those areas, with the price drop. In some parts of California, according to the report, the cost is lower than $1 per square foot.
