Published prices, Durbanville, the Northern Suburbs and greater Cape Town
Nobody in this trade publishes prices, which is exactly why quotes are impossible to compare. Here is ours: the product prices, the coverage at three coats, all in one place so you can do the arithmetic yourself.
Problem & approach
Price per litre is the most misleading number in waterproofing. Every job is priced after a site visit, as one fixed price for the whole job. Per litre it is. Per waterproofed square metre that lasts a decade it is not even close, because the cheap figure assumes a single thin coat over an unprimed roof, which is a colour change with a shelf life of about eighteen months. The second trap is the missing lines. Primer, detail reinforcement at bolts and laps, the clean, and the third coat are all real costs, and a quote that leaves them out is not cheaper, it is smaller.
So here is everything, published. Rubber Sealant® is R199 for 1 litre, R790 for 5 litres and R1,990 for a 20 litre drum. Every job is priced after a site visit, as one fixed price for the whole job. Manufacturer's recommended retail prices including VAT, confirmed on enquiry. At the manufacturer's three coats a 20 litre drum covers about 40 m² on smooth flat surfaces, about 33 m² on metal sheeting, about 27 m² over old torch-on, about 20 m² on concrete or brick, about 17 m² on roof tile and about 13 m² on slate.Every job is priced after a site visit, as one fixed price for the whole job. Williams & Co does not carry out asbestos work. Take any quote you have and check it against these. If somebody is a third cheaper, ask which of those four things they are leaving out, and get the answer in writing.
