Complete heating system installation

Dalex systems installed a complete heating system with boiler, new pipes & 7 radiators in one day with minimum disruption, they worked very efficiently and cleanly leaving no mess, all rubbish was removed at the end of the job all workers were very pleasant and helpful and explained the workings of the new system. After installation a rep from the company came to check the installation and to make sure we were happy with everything and arranged for a joiner to fix a small problem with the floorboards, the joiner went above and beyond to rectify the problem and extremely helpful with a couple of small decorative problems due to the installation, not the fault of Dalex, the rep also made sure we understood how to use the new system.
Altogether a pleasant experience with little upheaval

Untidy pipes showing

After having a new gas boiler fitted there were untidy pipes showing.
David Brownlee was the super nice joiner who came in and boxed the pipes off. He did a fantastic job and I'm very happy with the result 😃
