Excellent job by a professional team Excellent job and done on time and a good price. Any issues resolved quicky without impacting rest of the operation. Will use Crystal Sigma for future installations and also the maintenance contract is a must. Good job, well-done team. Happy customer. Definitely would recommend.

Recommendation I recommend Crystal Sigma

Crystal Sigma work at our property Crystal Sigma have carried out a number of installations for us at a residential block we own, including in line electric boilers, air source heat pumps and general heating and plumbing works. Their work has always been excellent, the premises left clean and tidy, and their response time and flexibility also excellent. We continue to use them for all our future needs related to the above

Friendly experts Jason and his colleagues were friendly and knowledgable: they clearly know their business well. Communication was always good
