Hi there. I have measured the lead pipe and it's 22mm.. I bought 2 MDPE Lead Loc Plus for 7lb, 23mm lead before accurately measuring. My question is do they need to exact match ie what's the tolerance as I read it's better to get a 22mm fitting for a 23mm pipe and shave it down so it's...

Hi, We had a patio done over a year ago, but have started noticing some damp and some smells. Upon investigating one possible cause could be that the patio seems to be badly laid and not following standard rules e.g. butting up against external wall too high, no drain for rain water and fall...

I've built a garden office last year and is well insulated, breathable membrane, air gap then cladding for breathable aspects. On the warm side i.e. before internal walls is vapour barrier which I research as the best for stopping moisture in winter, and effectively creating a sealed box. The...

I am doing a patio with pure mint flags and want a light coloured (no iron stains either from normal mortar) joints filled with something strong i.e. grout or mortar? Conflicting opinions from 2 builders: 1 says go for easy jointing compound, swept in and done in no time. The other suggests...

hi there. I have planning permission for a loft extension (needed as it's a flat i.e. not permitted dev rights) and is about to lapse. I've been told I can just start the job a number of ways to keep the planning 'alive' but might need some sort of evidence. I've got structural engineer...

I have rather regretfully painted the walls (OSB) of a garden office with Dulux exterior weather shield masonry paint on the advice it would be fine. I now have a smelly office which is rather annoying. I believe it’s the biocides in the paint that is the smell. I’ve painted over it with an...

I have purchased new scaffold boards which I intended to lay as floorboards in a garden studio, but when they arrived I noticed they seemed quite damp and some heavy. Obviously rained on for a while. I’ve stored them stacked with ventilated gaps, but now it’s not summer they don’t seem to be...

I know this sounds familiar, but have read the posts and find the info I need, so any advice appreciated. So from top to bottom I was thinking (for garden studio); - 225mm x 38mm wooden floor boards - (maybe VCL or foil tape joins in celotex sheets) - celotex - concrete floor Will the floor...

Not sure where to post this query, but hope someone can help. I've mostly built a garden studio, insulated, cladded and now onto the internal finish with the vcl, but am unsure how to approach the electrical sockets, window frames and doors. How do you get around sockets, frames, fixings for...

After much deliberation, I decided to clad my garden studio in ply sheets and some cedar as an added feature. I will cut the ply sheets so they have a shadow gap between each one so will definitely need to treat the edges properly which will be exposed. I want to stain the ply a dark...

Been looking for weeks but cannot find any specific details on this; I'll try to explain but apologies if I waffle. I'm building a garden studio, timber frame, without overhang. The top of the cold roof has 25mm air gap above celotex insulation then osb roof, then will be epdm. The walls have...

About to wrap my timber framed garden office with the breathable membrane and battens but am unsure how the edge detail is finished with an EPDM roof. The cold roof rafters end flush with the stud wall rather than any overhang. If I go by the limited diagrams seen so far (see attached), then...

some advice needed. Before I ask advice I will be getting any wiring signed off and completed by a qualified electrician before connecting to the house mains. I just want to save some time / money by running the cables around the stud frame of my garden office and want some basic advice if...

Hi there. I've had some very helpful advice from this forum recently, but need some more if possible. Just wanted to confirm the insulation specs. The plan is currently; Floor 75mm PIR insulation laid directly on concrete with glued battens spanning front to back as a fix for scaffold...

Hi, I need some advice if possible on the best type of membrane for a timber framed structure for a garden office. I was going to have the stud wall, membrane, battens, then ply cladding sealed with Osmo oil. Parts of the cladding might be open joint cladding with vertical battens, but am...

Hi, going nuts here a bit. I'm trying to do the dims for my garden office and am doing 5x2 roof joists with firring strips on top for the pitch. I am doing 400mm centres, but this does not seem to work to get the end of the OSB (1220x2440) to end on half the joist. I've read somewhere you do...

I'm building a 4.8m x 2.8m (ideally) garden room and need some advice on the base / subfloor and possibility of overhang on the floor joists. As you can see in the image, I've got a concrete slab (not insulated) that I was going to sit the 3x2 treated joists directly on with DPC underneath each...

I'm thinking about materials to clad my garden room in and was going for ply panels or battens which I want to stain/paint black. Ideally with ply I'd like to see some wood grain through it, but am confused about the different types of ply. Marine ply is too expensive and possibly overkill, WBP...

Hi there, Firstly I'm new to this forum, so apologies if I've not posted in the correct place etc. Any advice on the following would be much appreciated: I'm building a garden office 4.8w x 2.4d x 2.5h. The concrete base is already done (about 80mm on top of hardcore, mot and dpm, no sand...
