Bouncing wooden flood

You want a carpenter / joiner or a general builder with strong carpentry experience. When you speak to them, use phrases like: “Bouncy suspended timber floor” “Edwardian floor joists need stiffening” “Possible joist deflection / loose bearings” That’ll filter out people who only do surface fixes. The most likely reasons (in order of probability) 1. Joists are undersized or over-spanning Edwardian houses often have: Long spans Joists that were acceptable in 1905 but wouldn’t meet modern standards Over time, they flex more, which gives you that trampoline effect and causes furniture to rattle. This is the most common cause. 2. Joists have loosened where they sit in the walls 3. Bridging / noggins missing or ineffective 4. Previous alterations Very common in terraces: A supporting wall removed years ago Fireplace hearth altered Chimney breast partially removed Even a small historic change can leave joists spanning further than intended. How it’s usually fixed (and what to expect) A good carpenter will usually: 1. Lift some floorboards 2. Inspect joists properly 3. Carry out one or more of the following fixes: Add noggins / strutting Cheap, effective, often the first step. Sister the joists New joists bolted alongside old ones to stiffen them. Add a mid-span support Timber beam Steel if needed (less common) Supported on sleeper walls or load-bearing walls below Secure joists to walls Using resin anchors or joist hangers if bearings are poor.

Hi, The bouncing is probably due to joist not being deep enough for the length of the room. Modern regulations take this in to account. Unlikely to be floor boards needing to be fixed down. Not an easy fix. Only option would be to lift floor boards and attach additional joists alongside existing. Hope this helps

The flooring in this setting is likely to be very old, over time flooring in constantly changing climates in the house makes the wood expand and shrink, is asvise the flooring to be replaced and whilst the flooring is up check the joints if on the 1st floor for play

It seems the joists are loose somewhere. It may only be a few but it's usually where there's been rot or loose mortar in brickwork affecting the joists support. The flooring needs to be lifted, partially in the beginning as only 1 2 or 3 may be only affected.

Hello, this is a common and simple problem to fix. Make sure the timber floors is free from wood worm and rot. The sleeper walls or joist underneath the floorboards need strengthening or supporting. A carpenter will be able to fix this for you.
