Carpentry- 16 May 2016
Obtained 3 quotes and selected Nathan after he visited the site and reviewed work and had conversation. Waited 2 weeks for him to become available and on first day contacted me to say he was pulling off the job. Apparently the door frames of this 1920's house required him to do much remedial work to get them square - primarily Nathan blàmed the plasterer who had overboarded the walls. Walls were passed for payment by two separate surveyors with over 80 years experience of the contruction industry. While it is accepted there were remedial efforts to make the frames square, this is to be expected on a house of this age - and perhaps this is where Nathan lacks experience. If Nathan had wanted to outline additional work and additional money this was open to negotiation - the most unprofessional thing is to turn up on the day of work starting and say you don't have time to do any additional work - especially as the job had been viewed before the work commenced. Didn't want to damage his reputation by providing "sub-standard work", but seemingly oblivious to the reputational damage of letting a customer down at the last minute. I have my doubts as to whether Nathan has the skills to work on houses of this age.

What experience do you have with similar extensions in Pentre?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Pentre extension builder’s ability to deliver a result that meets your expectations.
