DECCA Aftercare
Due to our extensive experience in water Tanks we have recently launched our new Repair and Maintenance Division. We offer an onsite Consultancy programme giving the client a recommendation of works in a detailed report.
Aftercare works included but not limited to recommendations are: Tank Upgrades, Full Tank Services, Connection or Fitting Replacements, Cleaning and Chlorination, Tank Strip-Out and Replacements.
Having not really had much experience in this area before, I was a dubious to say the least how this GRP Housing project would turn out. "How wrong could I have been". This product surpassed everyone at the company's expectations and then some. Decca really pulled this one out of the hat and everyone I've spoken to on site is very impressed with the look and quality of this. Needless to say, the next time I need something along these lines again there's only one company I'm turning too.
Hi Decca, Just a quick line to thank all of you for all your hard work to get my Balance Tank turned around and installed so quickly. Loving your work.
