Damp proofing - DIY vs professional

Gday,

I'm investigating damp proofing by gravity-fed injection method.

(House is a Victorian Terrace, solid brick on Bluestone footings)

Quotes for supply and installation range from $4500 - $7000 for the whole house (basically all walls need it)

Or there's the DIY option from TechDry. Which will come in around $1760

Basically you drill 10mm holes into the bricks and fill with fluid.

Obviously I won't get the 20 year guarantee, but I visited them and was given good clear instructions, and told the product is the same as if installed by them.

I read a couple of very old posts about satisfactory DIY attempts, just wondered if anyone else has used the product and what they thought of it? Particularly ease of use/ how it has stood up?

Thanks in advance.

Ben.
