Damp proofing & removal advice/DPC/recommendations MEGATHREAD

[mark1867]

Can anyone recommend anyone who can deal with damp problems? Noticing damp patch on wall in the attic room which is affecting the ceiling to the room directly below slightly. I believe that it caused by rain water leaking through external wall but by no means an expert.

 

Based in S6 area. Thanks for your help

Hi all, 

 

Apologies if this is the wrong place - I had a look on the megathread but couldn't find many recent recommendations and would also like advice. 

 

I have had a pre-purchase homebuyer report which has picked up on damp and boring beetle in the cellar. 

 

I would ideally like a free inspection/quotation for works on both issues as my outlay before purchase is mounting up. However, I have heard that free ones may just recommend new DPC as it is in their interest to obtain work. 

 

Can anyone advise on free vs. paid surveys and give any recent recommendations?

 

Thanks

Hi,

 

The truth is damp proofing is a con, as they drill holes and inject either under pressure or a gel into the holes. The theory is great the reality is different.

 

One wants a complete barrier from rising damp, and the only one is an actual physical cut through the wall, and placing a membrane through it, this cutting off the damp completely. That is 100% guaranteed.

 

Injection is suppose to do this but the porosity of the bricks, crappy mortar and cracked bricks make it more hit and miss, as damp will be reduced but find its way round or through the new. Doing two rows helps more and three as you can guess gets expensive.

 

The fact is its not rocket science, first you drill a 10mm hole and with pressure injection into 2-3 inches in the brick and inject. IF it is gel then in a 9 inch wall about 8 inches, just tape the drill bit at the right length. The gel uses a gun, and you just squeeze the trigger. You can get the whole lot for a fraction of the price of the so called professionals, who are just after the money. A certificate is a worthless piece of paper, except is you want to sell, and then it means something till like you the next lot find the firm is no longer.

 

You can do a better job, and it’s done right, yourself, otherwise shell out hundreds for a bodge done in a few hours.

 

After it is injected the wall in theory dries out, the rate is one inch a month, so 9 months to see if it cures the problem, so the grab the cash and run brigade can then just fob you off.

 

Most builders are all mouth and no trousers like politicians; they are in it for the money.

Injecting the bricks and not the mortar leaves a path for the damp to rise. Damp company my sister used 3 yearS ago  injected a paste into the mortar every 6 ish  inches. When I queried this I was told that Injecting the bricks was the old way of doing things. None of the damp has re appeared by the way.
