Ash tree reduction

[cray1]

I have two Ash very close to house  (purchased last year)  and they were reduced by 

4 m in Feb this year, probably a third of height.  Can they be reduced again this Autumn/late winter, or too soon?  Dont want to remove completely, due to possibility of heave, or reduce too quickly but not that happy with the shape at the time, but they have produced new foliage this summer.

 

Will it be safe to reduce again this autumn and/or is heave more to do with total removal of trees?  Will reducing in height over time help with possibility of subsidence (none so far).

In our current climate we seem to get bone dry summers followed by months of flood.

The soil is expanding and contracting with or without trees.

especially this summer - my place was underpinned years ago before I bought it, and after the long hot summer this year a few weeks ago my front door started rubbing on the frame in the top left corner, had to shove it shut. Now we've had some rain (to expand the soil and jack it back up again) the door isn't rubbing

Most structural engineers don't know much why it comes to trees , I once argued with building control about a tree 50ft away from footings being pulled in greensand,  he was trying to suggest footings  a 16ft Leyland would cause issues , when challenged about it they use a guide from nhbc that's not based on tree species or types of soil/rock below ground level , So really a load of bollocks .

Ive also heard of this crap take a 1/3rd off it per year before the trees gone.

I'd  suggest talk to your house insurance, ultimately if it goes wrong they will foot the bill, also they might suggest they aren't that bothered about tree removal  because they deem it far enough away from the house  or might stipulate otherwise .

Ive had the miss pleasure of dealing with structural engineers in other disciplines they aren't that bright.

Ever thought about a professional tree surveyors report ? Might be a bit more in depth than a structural engineer and more relevant.

There are people on here with way more knowledge than me about such matters, but from those pictures, I would have been firing up a saw immediately. They're some of the ugliest specimens I have seen, and at that size, I wouldn't have any qualms about removing them. 

When I worked for a builder friend, the building control officer in one area was absolutely petrified of Leylandii. If he saw one anywhere near, the footings had to be bigger/deeper. 

Once upon a time, a neighbour rang and asked me to fell the oak tree near his mother's house, as it had been deemed  responsible for cracking/subsidence. I refused, and told him that the oak tree wasn't the culprit. He replied that he knew it was the big Willow, I knew it was the willow, but the insurance man said it was the oak, and it needed to be felled for the payout.
