Warning do not use this company. They appear initially to be friendly and polite.
Bobby doesnot seem to know much about how to treat concrete cancer.
Agreed in writing to a fixed quote with no variations five year guarantee.
Showed up this morning left a mess peeled off cement render off balcony ceiling then proceeded to tell me he had not quoted accurately and tried to vary it.I said this is not acceptable.
Bobby then stormed off not resolving the issue
leaving the mess.
Underquotes to get the job tries to vary it not honest
not trustworthy has little knowledge of how to treat it.

Very impressed with Bobby's standard of work. He has done quite a few jobs for our Strata Plan and nothing is too much trouble for him. He's a genuinely nice person and cares. I would happily recommend him to anyone looking for abseilling work, waterproofing, ceiling replacements and painting.
