Friends recommended William from De Exclusive and we hired him after comparing his consultation with that of the other IDs we visited. One extremely important criterion in finding a good ID is that he/she must be willing to listen. William listened very carefully to ensure he understood our needs and preferences. The other important criterion for us was workmanship. Part of the reason we were convinced by our friends' recommendation is the workmanship we can see in their houses. William and his team did not disappoint us. Furthermore, unlike the many horror stories I hear from my neighbours, William and his team were prompt in their work and there were no unnecessary delays. He was also understanding and tries to accommodate to our schedule where possible whenever site visits were needed. We strongly recommend William to anyone who is looking for a reliable and experienced ID!
