Floor insulation and new flooring contractor

jay0109 · 30-06-2020 11:06pm #1

Looking for some advice and recommendations please.

I want to get insulation put under 2 living room floors - 1960's style suspended flooring. And then new flooring installed in place of the cheap carpet currently there - probably semi engineered wood floor.

Does anyone know of a contractor/company who would do both as part of the one job?

Based in Sth Dublin.

Thanks

The skillsets are not complementary in my opinion and getting suspended timber floors insulated properly, c/w being airtight is not an insignificant task.
get familiar with how it should be done here

or elsewhere.

The insulation and airtightness job should leave you with a usable subfloor what you wait for the new finished floor to be fitted, there's no real advantage to having them done together.

The skirting will have to come off for the first job and you may want to have that replaced (rather than refitted) by the people doing the finished floor.

Thanks all.

So 2 separate jobs. Who would do the first, the insulation...a regular builder or a specialist flooring insulation company (does such a category of firm exist)?

If anyone has any contractors they'd recommend, please PM me.

Insulation and air tightness.

This is critical. Many builders doing small jobs are unconcerned with/unskilled in air tightness.

If the job is done wrong then you'll get drafts coming up through and around the subfloor, pushed by pressure differences between the air in the room and the air under the floor (vented from the outside, and necessary to ventilate the joists).

This is probably all in the code of practice Calahonda52 linked to.

I'd be inclined to whip out the timber and pour a concrete floor with 4in insulation. Much faster and cheaper, you could do a fair bit of the guntering yourself if anyway handy.

I'm in no way handy at all!

And wait maybe 6 months for it to dry out
