Other than same question with Haruko, does Fosin provides service of measuring and installation of the rods? How much do they charge?

I'm looking for rails and curtains for my new house.

This is a quotation that I got from a curtain make:

1 sliding door 9'4" tall X 8'4" width
1 window 9'4"tall X 7'6" width (black out)
2 windows 6'10" tall X 7'6" width
4 sets waterproof roller blinds 4 feet x 4 feet.

All french pleat blinds, aluminium double tracks with organza layer except roller blinds. Total 4.3K.

Reasonable?

Weikee, mind to share the material you buy from Baagus?

Nilai 3 provide rail installation to Shah Alam? How's the quality?

One more thing, is there a need to specification I should take note when it comes to the curtain tracks? They told me it's double track but is there anything I should ask like the thickness of the aluminium they use etc? Wooden and aluminium track, which one is more durable?
