Thanks all.
I’m going to check their work and knock on the door, if any good I’ll ask for 2 or 3 more places even if I have to drive around for a few hours.
I still have reservations obviously, but I’m not writing them off straight away.
Even though we’re putting the house on the market I’d still want the job done right.
My number one learning from the property renovation is that it’s way easier when you have time, as in if I had 4 months I could wait for the right firm, a reasonable price.
Get a written quote,
ask for material and labour to be broken out separatel, listing the material to be used and approximate qty.
call the local builders merc & check prices ( expect the quoted prices be similar to over the counter prices, in reality the contractor will be getting IRO 20% lower but not reflected in the quote you get)
the labour IMO should be approx £150 day per man + £200 for lead man per day, (including profit and overhead) machinery etc will probably be included in the labour element Total ( probably) mini digger £150 per week (hired), fuel negligible, whacker plate £25 - £50 per week, this depends if machinery id hired or owned, much less if plant is owned and not hired!
muck away - grab lorry: IRO £480 per load (1 load = 9 m3 approx or 18 tonne) eg. 10m x 10m x 0.15m dip = 15m3 approx two loads
ask how long it will take ? this will help determine how much labour has been allowed and if the time is sufficient To allow the job to be completed properly?
e.g. Assume 4 men 1 week min. £150 x 3 men x 5 = £2250 + £200x 5 days = £1000 total lab = £3250 ( if one week is quoted)
don’t forget to factor in a healthy profit margin ! No profit margin smell a rate !
if all that checks out, ask the contractor if he had any pr with you holding 5% of the total for 6 months to give you a fall back situation in case remedial measure are required later on. ( it’s called Retention in the building game)
finally do not pay upfront For material etc.
I hope that gives you a starting point to examine the costs
