Landscaping- 29 Jun 2026
Dan, Lee & Rob are a great team each having their role and skills to contribute to that team dynamic. Dan engaged us at each decision and made a few suggestions to improve our design which resulted in an even better outcome. Attention to detail was great and the team listened if we had any concerns or amendments to make as the job progressed. They worked tirelessly even through 35oC heat. True work ethic. Thrilled with the outcome and finish. Really glad to have met the guys and have them deliver everything we asked for.

Ben at Jenstone did a full refurbishment including all new plumbing works, including an external oil fired boiler, and a rewire through out. He completed the work to the specification exactly and the overall finish was excellent. He also went above and beyond to get the best prices on materials costs and arranged all of the materials delivery’s making the process for myself a pleasant experience with the refurbishment rather than a head ache. If you are after someone to not only complete the work, but project manage, Jenstone are the outfit to use. Very professional indeed.
