How we work
No surprises, in writing
Old houses hide things. We say up front what we know, what we will only find out once we open up, and how we will price it.
Visit
We come and look, take measurements and listen to what you want from the space.
Written estimate
Every item priced line by line, with allowances clearly marked where the work depends on what we find.
Programme
A week-by-week plan, with engineer, Building Control and Party Wall steps built in.
On site
A director on site, a tidy job, and any change agreed in writing before it is done.
Handover
A snagging walk-round together, certificates passed over, and the house left clean.
