5* Service, from a 5* Company! Professional, honest and reliable company that can not do enough to make your experience with them smooth and easy. Punctual, ensuring that they are always ready to start the job on time. Very obliging too with times and days. They keep to their word and know their stuff!

Company are brilliant Company are brilliant, emailed them and got back to me straight away regarding attending a site and quoting the works that are required. Got a phone call after they surveyed site and advised they will send costs over which I received shortly after. They kept in contact after regarding any updates. Great company and very helpful.

Well priced, helpful and friendly We got in touch after receiving a quote elsewhere we perceived to be extortionate. within days of enquiring, Crystal Sigma were in the premises and produced a quote which was far more competitive. Following that within a week or so we had the Unit fitted. Very pleased with the service from the office staff as well as the two guys who fitted the unit. Very impressed with the entire service

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.
