			<![CDATA[Hi - Novice calling!!<br /><br />Our Dormer Bungalow was built early 80's and has a very attractive external brick with a coloured pointing which really makes it look good. My concern was raised when the Cavity Wall Insulation salesman told me that his system using 22mm drills was better than the other we had seen because the competitor uses 28mm drills. Checking our own pointing gap I don't see how he could avoid damaging the brick corners even with a 22mm drill and I am not convinced that he could match the pointing colour either.<br /><br />Is there an alternative, because I don't want to spoil the whole look of the place, just to save the planet!<br /><br />RoyC]]>

			<![CDATA[There are a number of alternatives. Just have a search around for wall insulation on the forum.<br /><br />However if you are concerned about the cosmetic effect of cavity insulation installation you won't like any of them; all are more expensive/disruptive, as well as either transforming the appearance of a house like yours or making your rooms smaller.<br /><br />Cavity insulation, when it works, is the biggest bang for you buck in insulation terms as it is subsidised heavily (I assume you are getting yours through a power company scheme). Everyone I have talked to both on this forum and in the real world swears by it, I wish we could do it to our house.<br /><br />S.]]>

			<![CDATA[The guys who did my house, filled the holes with a mortar mix with dyes. The lad  mixed 'em up by eye and the result is very good. A few holes  can be seen because of the different surface texture and the rest (30 +?) can't be seen and I reckon I know  where they are.  All depends on the operatives.<br />          Frank]]>
