Our living area has 3.6 m high super heavy industrial-style sliding doors that had started rumbling during opening and needed replacement rollers.
Stephen did an excellent job. He replaced 2 sets of 2-wheel rollers with 2 sets of 4-wheels which are capable of carrying a heavier load and should last for at least another 10 years.
We are very satisfied with his knowledge of the problem and the quality of his work.
Thank you Stephen.
