Am trying to ascertain how difficult and rough idea of cost to remove a chimney breast. The chimney stack, which was on a flat roof, has already been removed and new roof laid. The room in question is directly below this flat roof. There are two flats below, one on first floor and the other on the ground floor - we are on the top.

I am planning to build 3.6x6x2.5m SIP board garden office on top of the concrete slab floor without foundation wall and feeting. Concrete slab floor will placed on top of the insulation. Can anyone recomend me the best underslab insulation material/product with high compressive strength and U-value take on heavy weight of whole garden office without foundation wall.

I am renovating a small 2 bed terrace house. There are numerous repairs required. These include roof and chimney repairs (stripping slates adding weather barrier and refitting), ground floor repair / renovation and damp tanking (floor joists rotted at front wall), kitchen door move (to existing window) / wall alteration (RSJ) and new fit units, bathroom new fit, new windows / doors (6 windows, front and rear door, 1 small velux), possible rewiring, yard wall demolition and rebuild, free standing garage demolition and removal. I am currently looking for quotes for works required. How much generally should I expect to pay? High and low estimate?? Cheers

We are planning a small single storey extension, approximately 1m X 4m, this will be an expansion to our current kitchen area and will involve knocking through the wall into the kitchen and adding an RSJ (unsure if timber or steel). The roof will be a slopped roof joining onto the vertical wall that is already in-place. There would be a single small sky light in the roof. We are based in the Midlands and the ground is a sandy ground, apparently better for building and foundations. What would be a ball park figure for the cost the building work, plastering and wiring together?

We would like to brick up our kitchen doorway and replace (and enlarge) a window opening, fitting small bi-folding doors (around 70'inch opening) on the same wall. Any ideas how much this might cost (minus the glazing)? Thanks.

Could you please advise me as to what product could be used to bung up the hole/s, in the cement, under the fascia, of my roof? Which would set hard, and be rat-proof. Rats have climbed up the drain pipe, to crawl into the hole, and entered the roof space. I need to deal with the problem quickly. Would I need scaffolding, as opposed to a ladder? It is in an awkward place. I have posted a job, but no one has got back to me, so I am considering doing it myself. Is there any kind of guard, that could be put around the drainpipe? To stop the rat/s from climbing up it.

We have a typical 50's built semi with a blockwork half wall instead of spindles on the stairs. We would like to change this to spindles and bannister. Is it a job for an experienced DIYer? If not, roughly how much would it cost to get in a tradesperson?

How can you prepare the ground before having a carport fitted? If I do it myself will it mean less of a charge if hiring a contractor to install the actual carport? Or does it depend? What do you think should be the case usually? Thanks.

I am having an internal wall taken down and RSJ put in but i would like the RSJ to be flush to the ceiling. The builder has said he needs to cut the joist back and then will re-join with 300mm joist screwed to the orgional ones and then hand these on the RSJ, is this strong enough ? or should bolts and longer pieces of timber used.. if bolts how many per joist should be used.

How much on average for a 3m x 2m extension on back of a terrace house, with a toilet. I was quoted £55k approx in the SE, but for a 3mx2m with a toilet at the back of a terrace house seems quite high, especially when I have to provide the tiles for the flooring and toilet and basin. Thoughts?
