Hi,

I've currently got builders in my home and have been doing an open plan kitchen Diner, removed 3 internal walls, put steels in, bifolds, etc.
They have done most of the job but only just realised that the timbers under the flooring are crumbling. They have stated it is because there hasn't been any ventilation in that part of the house. An extension was build in the 60's with a concrete floor and no ventilation was put in.

Ive checked the timbers and they do need replacing and ventilation being put in.

The builder has quoted £18k for the job though and I am struggling to understand why this is so expensive.
The area is the picture below plus approx another 5m2.

Does this seem far too expensive? or justifiable?
Its a job i have no decision over as it needs doing!

Also does anyone know if such things would be covered in home insurance?

appreciate any help with this

thanks

You're being fleeced. There's something called "extras" in the trade - any deviation from the agreed work is charged at 10 times the rate. Just treat as a separate job and get quotes.

A lot of people just convert to insulated solid floors these days.
 
As cdbe says: fleecing in progress. Big style.

Just to give you a perspective I've recently finished a full refurb of a rental after the tenants from hell were evicted. Part of that was dry rot in the kitchen floor. All the boards came out and 4 joists. I set new plates on sleeper walls and did several sprays on the rest of the joists and the masonry. Less than 2 mandays all in. My pal then set the joists (not straightforward as the floor wasn't level and had to be tweaked and boarded the lot in one day, 3m x 3.5m and he had to go under an existing cupboard.
 
Get someone else in to quote for the work then you'll know, if your builders any good he'll understand it's a large unexpected cost and you need time to look at your options

How much did you charge for that?
 
6 lengths of appropriately sized treated wood, some brackets etc.
Certainly not £18k worth of work.
This could be done yourself in a weekend.

That's an entirely reasonable quote - just as long as the new joists are 18 carat gold rather than 9 carat!
