Browse Forums General Discussion 1 Feb 26, 2014 7:45 pm A friend of mine is thinking of making an offer on an old brick cottage in Hobart. We can see that it has rising damp; efflorescence is visible in several places on both the internal end external brickwork, and the paint is bubbling. I suspect there was no damp course installed when it was built. The house was built in 1910 and is 2 bedroom, 108 m2 (about 12 squares). I'm just trying to get a rough indication of how much this might cost to rectify, so we can take it into account in the purchase price.... it's really hard to find any indication at all online, and I don't even know if we're talking about $1000, $10000 or $50000! Has anyone had this done? I'd love to hear what company or method you used and how much it cost you. Thanks! Re: Cost to install a damp course 2Feb 26, 2014 9:42 pm Gday I wouldnt be surprised if the footings are sandstone. About a year ago i renovated an old terrace from the early 1900's its actually on the heritage list here in Sydney. Had the same situation and it wasnt confined to one area. I used an injection application into the affected areas and it worked like a charm. im not sure of the price someone would charge but its pretty simple to do just get a 10- 12 mm masonry drill bit and and drill horizontally into the bed go at least 3 quarters of the way in do this every 30-40 mm.you will find that the worst area's are really quite wet. the mortar back then was often done with minimal if any cement as was the render finishes. Then in goes the silicone based injection material. The kit i brought for the job had nozzles and a little version of a caulking gun. Not sure where you will find the silicone based material you use in hobart but im sure a hardware would stock it cant think of the brand name off the top of my head but just mention dampcourse injections and you should be led to something. Hope this helped and good luck Re: Cost to install a damp course 3Feb 27, 2014 9:46 am You could ring any number of these guys to perhaps get a quote of what the repair cost may be. http://www.yellowpages.com.au/find/risi ... hobart-tas Or if you prefer DIY http://www.saltdamp.com.au/diyweb.html Settlement 1/2/12 New Shed 23/3/12 Slab poured 27/3/12 Frame complete 4/5/12 Roof complete 1/6/12 LOCKUP 29/6/12 Our new build blog http://kareenhillsownerbuild.blogspot.com/ Re: Cost to install a damp course 4Mar 02, 2014 10:11 am Thanks for the replies. I was hoping to find an accessible ballpark figure on the internet outside of business hours, but it seems like maybe there isn't one! My friend didn't put an offer on that house in the end, as she decided it was too much work.
