Trouble with noisy & bouncy floors, check out these information pages, including a great video (please WATCH this video FIRST) showing simple bridging between joist (cross-bracing) and a method to dramtically improve the poor performing cross bracing. This great video is from a North American Company and features bouncy problems with I-Beam I-Joists. Charles Church (and Persimmon Homes) use I-Joists from JJI Joists in the UK. JJI License the joists design from a Canadian company (North America) called Nascor. Nascor licenses the I-Joists across the world to 18 different companies, including Australia, UK, USA etc.

But be aware, their are different performance specifications for I-Beam joists, depending on thickness of I-Beam joists, depth of joist, spacing and span. Together these give a Suitability Index rating (SI rating). Charles Church used the lowest possible, and cheapest SI rating in our new home. And it didn’t surprise us to learn Charles Church has done this in other new homes.

Other information on bouncy flooring, such as that installed in our home by Charles Church (part of the Persimmon Group plc, which also trades as Persimmon Homes). This is a demonstration of bouncy floors, and brilliantly they quote ‘you’ll end up with nail pop, after nail pop, after nail pop’ by doing what Charles Church do and attaching ceiling plasterboard directly to the joists. Lastly some text based references to bridging, sistering, cross-bracing, straping etc.

But first check out the great video at the top, where an engineer has set up 3 test floors, clearly showing the problems with the cheapest fix, cross bracing with a herringbone noggins, and then a very simple way to dramatically improve the performance. The first method shown is similar to that Charles Church is trying to push onto us and other homes. The last method is far superior, and avoids the problems with standard herring bone cross-bracing.


It’s the same story over and over with Charles Church, as we wait for the faults to be fixed – well to be investigated, well actually just for the company to make a clear and understanable statement about which faults they agree are faults, and which they might one day in the future actually start trying to fix (or even better properly investigate first).

Guess Charles Church does not consider it in their interest to actually honour the sales and marketing claims they make to new home owners (like ourselves) when they sell the dream . . . of course, ultimately the buyer is the winner . . . funny that, it doesn’t feel like we were winners, we very much feel like the loosers whilst Charles Church are laughing all the way to the bank.

Interesting reading on the Charles Church and Persimmon Homes Owners Forum. The link takes you to posts of the workmanship from the perspective of new home owners.

Similar to us, they do not sound happy with the builder. The advice seems to be for owners to talk to each other and work together. One can take each area of concern, for example one can research and pursue an internal doors issue, another can research roofing issue, another heating problems. Whatever combinination of concerns you may have, by working together and being united one can expect a better result for all, and hopefully avoid an estate with ‘alternative’ fixes on each home, so a perspective buyer might have concerns for all, as they can’t tell which had a quicker fix and which had a satisfactory fix.

Most upsetting from the forum post, is the mention of a known fault being repeated. Our own experience shows this as something we have personally encountered, with predictable inconvenience and anxiety.


  • Bob: Perhaps the New Home Builders are enjoying the econmic climate a bit TOO MUCH :(
  • M. Farley: Walked around a new Charles Church Show Home last week, and found same issues discussed above, noisy bouncy floors. when will they fix this? From read
  • Debbie Brown: Neat idea! Can't beat something that makes cake easier to eat and carry.
