dpc

I live in a 3 bed 1930s semi detached I got my house painted and the area on and below DPC was painted in Zinsser all coat. I am now trying to remove this paint so I can get it repointed in lime mortar and make it breathable. Then get a aco drain fitted due to floor level. I have used home...

Hi All I'm building a non habitable outhouse amd confused as to where I out the tye DPC and cavity tray. I have laid the raft. I am 3 courses up with Eng bricks on outside and 1 block inside making both level. By the time the outside patio is laid it will be 2 bricks (150mm) above it. I...

First of all - thanks for reading. I'm an amateur DIYer so please forgive me if I use the wrong terms or just generally sound like I don't have a clue... I basically don't :LOL: I bought a (brand new) new-built house in September 2024 and have had numerous issues with the company - fobbing me...

Hi folks. I'm planning to paint the floor (after rescreeding) and the breeze block walls on the inside of my garage. I'll paint the breeze block with a normal interior white emulsion, probably watered down to seal. At the bottom of the interior of the external walls there are two rows of brick...

Purchased new home couple years ago - The DPC at the front of my house is visible however, at the rear I can't see it? We haven't had any damp or mould issues so far in any of the rooms facing the garden. I was wondering if I should paint on bitumen DPC or should I leave it? Don't want to...

Hi I’ve removed rotten decking and planning to lay a patio. Patio level needs to match other paving, which is 3 bricks down from the dpc in these pictures. From patio to door threshold height will be about 260mm. My problem is building a step to the back door. The air bricks are under the door...

Halfway through installing this patio, the stone pavers are set in mortar and go right up to the house. There is a decent fall away from the house. They're about 80mm below the DPC. Is that enough to prevent the wall getting damp?

Hi All, Bit of a DPC/DPM conundrum I've got here. Long story short, I'm self-designing an extension which is required to go on a raft slab. I envisioned this would end up on a raft with a boot/stepped edge detail, however my structural engineer has recommended (and designed) a flat raft slab...

Hi, go easy on a lady! looking at our new extension walls, it looks like the DPC on the inner wall is higher than the original house. The floor joists in original house are sat on a wall, and I think an old DPC material... this level is lower than the DPC hanging from the walls in the new...

Hi Everyone, TLDR; How should a DPM in a new floor slab connect to the DPC in the walls? Does it seem like I should add a DPM to the walls based on the plastering we found? I'm trying to get my head around how the (rising damp) moisture management in my house should work. It's a 1930s semi...

I have a driveway where the previous owner has built up right to the house raising the external ground level almost up to the DPC - the DPC is on top of the first course of bricks from the ground in the pics. How would you reduce the ground level on this driveway. Would you remove the line of...

I have a subfloor void in a room which has a unused fireplace of a 1930s semi in the north west of england. There is lots of white deposit on the subfloor void and when I dig the floor the ground is like clay. Is this deposit mould or salts? I cant see any on the underside of the floorboards its...

Hi all, I am after some advice with regards to damp in my single skin detached garage. I have had a damp survey done and it confirmed that I have damp bridging into the existing concrete slab floor from the engineering bricks below the DPC. Apparently fairly common in garages. No visible signs...

Recently bought a house and didn’t pick up on survey a brick missing below bay French doors that jut out from the house (see picture). It’s below the DPC with some sort of polystyrene I think at the back. Would this be a missing air brick or something more major to worry about?

Hi everyone! I'm looking for some advice on converting my brick outbuilding to the rear of my house into a small home office. I am just trying to guage and plan out what exactly I will need to do it this (and how much I can do myself) to achieve this and would really appreciate some guidance...

We have identified a damp issue which is much worse than we thought. The downpipe from the gutter had been failing for some time (bodge job by the roofers). The frame for the front entrance rotted and we had to get the frame nearest the corner cut out and replaced and had someone in to do the...

So I live in a house buuikt in 1890. It’s an end terraced house down the side of the house the bottom course of bricks is very weathered and the mortar is in a bad way. The side of the house is rendered above the DPC. There was a an injection damp proof course done before we moved in and all...

Right, here we go.. I have a detached garage built in the sixties with a substantial plinth. The garage is now gone allowing me to have a good look at the plinth. It's square and has a depth of over 150mm. It's downside is that there's no DPM. The plan is to build a garden office on top of...

Occasional DIY bodger here, haven't done external work before. The problem is damp on the floor in the garage which was built as a recent extension before I bought the house. There's a drainage channel on the outside of the wall that isn't rendered and I think the water's coming in there...

Hi Appreciate some advice please Side of a double length garage build 1920 ish, probably 15 metres long. Wall is solid brick wall, but not really - never seen this type before, it is two courses bonded with a few odd headers every 7 or 8 courses with a 1-2cm cavity. Due to weathering over...
