certificate of compliance

Hi,
We bought a house built circa 80s about 2 years in Co Wicklow for which we omitted to order a structural survey for. This was a mistake as we realized all the work that needed to be done on it . (attic insulation, new widows, boiler...)
We have beautiful wood flooring but again very noisy and not stable. The floor is 3/4" tick and have been lay down directly on the joists with 60 cm span.. I am considering 2 options : 1- Removing the floor to add extra joists/noggins and underfloor insulation or 2: add plywood to add stability.. option 2 is preferred but measuring the ceiling height is only 238cm which is below regulation.
Anyone could provide insights on how this problem could be addressed please?
thanks in advance

This items are non structural so a pre purchase survey would
Not have helped you other than highlight the issues. The sellers would not have had to upgrade them or anything so you still would have to make the choice of buying based on upgrading yourself (like buying an older car).

Get an engineer to advise on how to structurally upgrade the floor. Don't worry about the 2380 floor to ceiling height as it's a recommended height and not a hard and fast rule.

Most houses back then were built to 2.4 and then people floored them so most are in and around 2380 including my own built in 2006.

Nowadays builders tend to go slightly higher.

thanks Kceire. Appreciate your response.

As above,
with a question or two:

1. when you say not stable, what do you mean
2. is the noise or the "stable" the main issue
   The answer here is important as the noise issue is a very difficult one to solve.
3. how is existing floor fixed to the joists at 60 cm.
4. what is makeup of the floor covering
5. What depth are the joists

Hi Calahonda52,
I mean that furniture are literally vibrating on the other side of the room when bouncing even 4 meters aside.
Both are an issue but mostly the noise queecking for every footstep. I think that the engineered flooring have been laid down without nailing/screwing and floating on the joists without attach.. The joists also seem no more than 20cm in depth. To summarize, even as a rookie my impression is that the installation was totally screwed up and a lot must be done to correct.

We need to move up from think as we can't advise properly on a think.

Have you lifted any of the engineered flooring?

While you think it's all screwed up I very much doubt that the subfloor is not screwed down

calimero242

you are right. No I not tried to lift the floor yet. I suppose I need a pro to take a look and advice. this won t be done before next spring anyways.
