I can vouch for this stuff. Had a very slow leak which was never found. Put leak sealer in and left it. Pressure not dropped for years since.

Normally they fit in a pocket, loosen a grub screw and pull it out. If you have to unscrew a threaded connection with seal, at least depressurise the tank!

It’s fairly obvious where the condensation is formed, just wipe it. If it doesn’t come off, on the inside. My windows (unoccupied new build) have loads of condensation on the outside every morning, presume this will go when it is heated?

d) Buy a sheet of 30mm PIR and cut into strips. Put that on the screed with full sheets on top. Fill 5mm gap with foam.

Have a look at expat forums. When parents had a place in Spain there were a few ‘men in vans’ shuttling stuff back and forth.

Have to agree with others, #1 must be your primary route. Hope you find a slim downpipe

Why do you want a standard door? I agree they are easier to use but how often and what would be used for (putting bins out, letting dog or cat out)? Have you got another back door, utility? Would you not want a wide opening from the kitchen in the summer? I would be inclined towards option 4

Assuming the gutters will be joined at the corner, it’s all down to flow rates. Maximum rainfall per hour in your area vs. gutter/downpipe capacity. Meteorological data from various sites, capacity from the manufacturer. Unless the architect intended 2 pipes for symmetry?

Can’t you remember if they used Lime mortar? If so try 1:3:6 cement lime sand. Otherwise white cement and sand at 1:5. Unfortunately sand varies in colour quite a bit as well, so unless you know exactly what was used, you will have to try a few mixes

If the roof is waterproof, it sounds like something is not laid correctly. A bit of rain might penetrate gaps but shouldn’t be pooling inside! Photos might help.

Very common I’m afraid. Could be difference in moistures content for some reason, then it will even itself out. More likely they have used a different mix of mortar, in which case the difference might become less noticeable over time. I would be more concerned about what’s going on at the bottom of that wall. Is that the DPC sticking out?!

I think these type of trays have ABS capping so the most obvious reason is a void in the underlying stone casting. Can you feel any flex in the surface?

What is the temperature of air coming out of the vents? What is the temperature of the exhaust air going out of the house? Photo of the unit would be useful.

Not sure of the regs but I would strongly recommend separate drainage for each house. Nobody wants to deal with someone else’s blockage! ASHP condensate piped to a small soak-away so it doesn’t puddle.

I didn’t put any vents in and last winter the shed was constantly damp with condensation. I put two vents each side, high and low level, dried out by the next day.

You should consider resale as well. Even if it is your forever home, things can change. I would minimize any lending restrictions. Are you against a masonry skin?

Not done that, just leave a gap at the bottom where it meets a cill

As the man says, they prefer to sit in their vans. No one will challenge you to provide CDM welfare facilities on an individual site, just a portaloo (to stop them going elsewhere)

£12/m2 labour only, not finished yet but looking about about £4/m2 for materials.

Excellent thanks! I will check what has been fitted and change it if necessary. It will stick out like a sore thumb where it is now 👍

Continuing this discussion ... My plumber has installed an AAV about 1.2m above (first) floor level. I am going to box behind the toilet and sink but want the top around 900mm. Any problems dropping it 300mm, practical or regs?

Stick the reveals in with PB adhesive, then put a few screws in once it has set.

Unless they are asbestos tiles of course 🤔
