Extensions- 7 Oct 2025
I cannot recommend Marcin and his men more. They were immensely helpful throughout a difficult (due to my inexperience and space and budget constraints) and rushed project. They worked to my budget and schedule and delivered to high quality - really an unbelievable job. If you choose them, you are in good hands. They are honest, reliable, and trustworthy.

Electrical- 9 May 2026
He was good on price for the first inspection and attended as agreed. However, I was less happy with the remedial quote. Several items quoted did not appear to be needed, while some items that did need attention were not included. Overall, fine for the inspection, but I would have preferred a more accurate and practical quote for the follow-up work.
