We're currently renovating our 1930s semi. We pulled the old laminate flooring up at the weekend to discover that 2 or 3 floorboards in the bay are rotten.
We looked at the airbricks outside and they are above the level of the floor inside - roughly at skirting level. There are no grilles inside so they're useless!
Outside, a new patio has just been laid. Its level is slightly lower than the original and the useless airbricks are exposed.
I'm a bit confused as to how they can be above floor level in the first place but, other than that, is there a solution? We don't want to replace the floorboards if we haven't fixed the problem and obviously ventilation needs to improve.
Any thoughts? @PigletJohn??
