“We've won 4 of our last 6 bids using Costimex estimates. Speed and accuracy are unmatched.”
Marcus T.
GC, Dallas TX
“Turned around a 22,000 sq ft commercial takeoff in 36 hours. Their MEP detail saved us from a costly miss.”
Priya R.
Developer, Toronto
“Costimex delivered a full BoQ for our Shoreditch refurb in under 48 hours. NRM2-compliant and spot-on against our QS check.”
James W.
Main Contractor, London UK
“Used them for three residential schemes across the North West. Pricing reflects real UK supplier rates — not generic templates. Highly recommended.”
Sophie H.
Developer, Manchester UK
“Their MEP takeoffs saved us a fortnight of estimating on a 40,000 sq ft warehouse fit-out. Won the tender on margin we'd normally lose.”
Daniel K.
