Removal of large fir tree Leylandii

[Dandeliondelilah]

Am revamping my garden after a summer of building work. Have a 40ft tall lone leylandii tree which I have decided has grown too tall for the plot and needs to go.
Some questions:

1. How much is it likely to cost to have it removed?
2. Do I need to get the stump taken out too?
3. Is the tree big / thirsty enough that I should be concerned about the possibility of heave (the previously parched ground suddenly becoming waterlogged) and affecting the house foundations (about 50 feet away)?
4. Is there an optimum time of year to get it cut down?

Can it be felled or are there buildings or other important plants around it which will mean it has to come down in sections?

There's a shed, a fence and a garage, so probably in sections (smallish, urban garden). I guess that means more work?

We had 2 removed last year and the stumps ground to just below ground level for £600.

2 more to do this winter then 2 more next winter😫

Costs a fortune and we live in a 'cheap' part of the world.

Stump - I could, otherwise you have to look at it forever!

Heave - you'd be best to ask your tree surgeon.

Time - any time over winter as there won't be any birds nesting. We had ours done in Feb.

I had about 5 or 6 of them cut down when we moved into our current property as they went along the whole bottom of the garden about 4 years ago and I think it cost about £400 this included stump grinding them which is best to do x

We do ours ourselves it's uite easy.
Just cut it back and keep cutting, then snip the branches into sizeable chunks or use electric saw (which you car hire cheaply) take to the tip or burn.
You can buy stuff for the stump that lets it rot away along with all the roots under ground.

At 40 feet you need a tree feller - not a DIY job!

Yes, I think this will definitely need the professionals.... I will get some quotes next month. Now the decision is made, I am itching to do it!

Once you get the stumps ground out, I suggest getting a tonne of top soil or compost to mix in if you ever intend to grow anything in the spot.

We have trees taken down a lot (woodland). Generally around here you'll be charged about £200ish for a leylandi since it's relatively simply to take them out but then stump grinding is really expensive and would be £150ish on top of that.

Really recommend taking down in sections even if you had the space to fell in one as it can make a mess of the ground underneath.

Make sure whoever you get is properly qualified not just a man with a chainsaw. They can give good advice and will most importantly be safe. Chopping down trees is easy, chopping down trees safely not so easy. I had a colleague who died due to an accident chopping down a tree in his garden so just how dangerous it can be is in the forefront of my mind.

If you can dispose of the waste yourself (burning / chipping) then you may be able to save a bit - we cut down a huge 75ft Lawson cypress we had the trunk cut into sections which my DH has chopped into logs (take a while to dry) and then they chipped the rest for us and we used it on the borders/ path.
