Far from impressed

1
Arrived late, no apology.
Apparently Seal are specialists in low-hanging fruit, unwilling to consider anything slightly out of the ordinary, inconvenient or difficult.
Scared of scaffolding.
Very disappointing.

Brilliant service

Seal fitted a new conservatory for me in April. Brilliant service, workmen polite competent and punctual, great job. The ‘Pearl’ roof has done a sterling job in this hot weather keeping the conservatory cool. We practically live out there now. Would highly recommend
