    What's causing this efflorescence on internal chimney stack?

    It was sealed a long time ago, probably at least 10 years+ and only lived in the house for 2 years so no idea. No bottom vent fixed and radiator in front of the old fireplace opening but no issues at all on the chimney stack apart from these salts. The bricks were completely white with salts...

    What's causing this efflorescence on internal chimney stack?

    In 2023 I had a chimney leak where the chimney stack below the roof line was getting extremely damp to about 1/3rd of the way down the stack below the roof line. In Jan 2024 we had the chimney sorted; all new lead, chimney pots and cowl all checked, new concrete flaunching and all mortar...

    Just had a small extension roof redone, pitch of the roof is 19-20 degrees. They have only done a 70-80mm headlap on each tile instead of the recommended 100mm for the pitch. Will this cause issues and should I get them back to re-do at correct headlap? Luckily haven't paid a penny yet. Roof is...

    Marley tiles on 20 degrees pitch

    How much would be reasonable for a roofer to charge for a 11m2 small roof? No scaffolding required, rip off tiles, battons and membrane and re-lay it all with new Marley tiles, no skip. Got a few quotes and intrigued to see what people think.

    Marley tiles on 20 degrees pitch

    Looking to get a single storey kitchen extension re-roofed as reaching end of life. Roof pitch is 19 degrees and Marley state the modern or edgemire tile can go down to 17.5 degrees with 100mm headlap but is it wise to do it or am I better off with reclaimed welsh slate? Only issue with slate is...

    New roof chimney leaking advice

    New roof chimney leaking advice

    Noticed that this top slate does not have a step flashing under neath and uses the one from the slate under, would this be enough to cause a leak in heavy rain or not really?
