Levi and colleagues installed Ubiflex for me to seal the joint between a roof and wall. The guys came on time and did a very neat job. It looks well installed, patted down, smoothed over and fixed. Some neighbours saw the result and promptly asked the guys to do the same at their house - so there's added testimony.
For a balanced review, two things to satisfy yourself of when agreeing with Levi what they will do:
1. Do get a detailed idea, when assessing the costs estimate, of how many people will actually be working for how long each, as actual working time may be less than you might assume from the overall proposal.
2. Make sure you understand in advance what exactly the guys plan to do to or on neighbouring property. You may find that what they consider appropriate (and take it they're allowed to do) doesn't match what you would expect to be able to do without prior discussion with the people next door.
So in summary: very neat and punctual job, but make sure you know in detail what they propose so you're all on the same page. Subject to those points I'd hire the guys again.
