I have a 1960s 2nd floor flat. Removed old carpet tiles from the kitchen to find what I would say are quite significant cracks and deterioration. In parts it seems the concrete is disintegrating as can be seen in the last photo which was taken after some light brushing and makes me think it’s...

I am somewhat out of my depth with a house renovation and would massively appreciate some advice regarding the kitchen floor... There has been subsidence at some point in the house and the concrete kitchen floor was uneven to the tune of around 50mm from high end to low end. I ripped off the...

Any help would be great here... We're moving house and have a 10'x8' garden office (only 5 months old, on a flat, concrete base) that we want to take with us... No problem in moving it (fortunately my best friend owns a crane firm!) but, and it's a big but, the property we're moving to is...

Hi, First time post - go easy on me. I'm building a side-return extension on my victorian terrace which also requires the removal of two internal walls which divide the kitchen into 3 rooms. To keep the house functional and to save money, my plan is to work my way back from the end of the...

Hi all, I am wanting to put a concrete base in for a hot tub in my garden. The garden slopes from the rear to the front. If the base is circa 2.5m x 2.5m the drop is approx 30cm. The base will have to be shallow at the rear and deeper at the front as I am building decking around it. A couple...

We are having to cut out channels in our existing kitchen floor slab for a new kitchen island. I will need to place an electric feed for the sockets; cold feed, hot feed and a gas pipe. I will also have to re-do some drainage so will dig out for that and re-cover. So I guess I'm keen on...

Hi, Lifted porcelain tiles a few weeks back and removed cement. Some of that cement was under the patio door base frame. Now there is a draft coming from that area (we can also see a black membrane). Is this simply a case of ‘plugging the gap’ / using sealant before levelling and installing a...
