Hi
What is a reasonable amount of time a builder should give for starting our extension?
Hi, unfortunately no one but the builder would be to give you a time frame due to jobs the have to complete or lined up etc
1 to 2 months a builder shouldn’t take the job on if they are to busy to do it within that time frame.
If it was me n had jobs on a would say 2weeks to 3 at most
Most builders like myself would be finishing off a job via quoting one. So id normally give month notice to get stuff in place and ordered .
Depending on the size or stories of the extension 2/6 months, bigger 2 story extension take more planning and structural engineers maybe needed! In most case work can start within 2 months
1-2 weeks upon customers approval is generally okay.
