Fixing sloping floors in a victorian house

HI just to bring you up to speed with your question . essentially the kitcken fitter has stated something that isnt poor practice , i suppose its acceptable practise to add a timber to the side of an existing joist however this isnt best practice and really doesnt adress dealing with point loads dead loads and uniformly distributed loads 2 weeks ago i attended to the floors in a student accomodation for a site agent essentially its acceptable to scribe new timbers over the existing floorboards providing they are not damaged by infestation of course or wet or dry rot its a quick fix and the new scribed timbers are placed over the existing joist positions worked out by the nailing matrix or screw positions where t and g or ply has been used thats the cheapest option if you have the money or the time or are fastidious in your approach strip off the existing boards and plant the scribed timbers onto the existing bare joists and overboard with any material you desire apply the new boards to the manufacturers instructions ie t and g always glue all tongues and grooves and apply 4 screws per board width equidistantly regards barry lord time served carpenter with a degree in joinery x

Hi, I assume you are living in a Victorian or older property? To fix this problem, you need to lift all of the floorboards in one room at a time and fix new timbers to the sides of the old ones (depending on the condition of the old ones, you may need to replace them,) then replace the boards on top of the new joists. You can do a room at a time, mo real need to move out of the property as long as you have space for the furniture. On a standard room, say 12 x 14ft it should take no longer than 2 days. Hope this helps
