Price still matters in construction.

But on many projects today, main contractors are looking beyond the lowest number. Why?

Because waterproofing failures create serious downstream consequences:

  • Delays

  • Defects

  • Programme pressure

  • Client dissatisfaction

  • Costly remediation


Builders increasingly value subcontractors who bring clarity, reliability, and professionalism to the project - not just competitive pricing.

The strongest waterproofing subcontractors usually stand out through:

  • Clear scopes

  • Structured communication

  • Accurate documentation

  • Realistic programming

  • Strong QA processes

  • Fast response times

  • Technical understanding


Main contractors want confidence that the subcontractor understands:

  • The drawings

  • The sequencing

  • The detailing

  • The coordination requirements

  • The commercial implications of changes


Inconsistent pricing, vague exclusions, and unclear documentation create uncertainty during procurement.

Clear tender submissions build trust before the project even starts. This is becoming increasingly important on commercial and high-end residential projects where coordination between trades is critical. The subcontractors winning repeat work today are often the ones making the builder’s job easier - not more complicated.

Professional systems, accurate QS support, and organised documentation all contribute to that confidence.
