I had hired William's firm based on his competitive quote, the extra 50 years guarantee from the manufacturers and that he was confident in being able to do an extra bespoke work linked to it. Whilst I was not able to present for the majority of the work, I have been told by my family that they had been polite and kept mess to a minimum. They had also kept us updated on the progress whilst they were working. Though, instead of finishing within two days, they had to work an extra third day to get the job complete. I was not concerned by this as I preferred that they take their time in doing a good and proper job rather than rushing it.
I always hold back from leaving feedback straightaway to review the work and especially with gutters as I wanted to survey the whole thing when it rained. As it turns out, there was a leak from a joint and when I had informed William of this, they had pop round within that same week and recified the problem.
All-in-all, I am quite happy with the work and the exterior of the house now looks updated and with confidence that the new materials will last (hopefully) beyond my lifetime.
