Renovations and Maintenance Plumbing Estimates: Accurate, Reliable & Tailored to Your Needs
What should i be careful about when estimating plumbing for Renovations or Maintenance jobs?
Renovation and maintenance projects come with unique challenges—working around existing structures, handling concrete cutting, and ensuring proper access for excavation. Careful estimating can prevent costly surprises on site.
Saw Cutting and Temporary Reinstatement
In most renovation jobs, you will likely need to saw cut the concrete slab. When estimating, make sure to:
🪚 Check all drawings carefully for areas requiring saw cutting
🛠 Allow for temporary reinstatement of the slab if necessary
Core Drilling and Fire Collars
If the job involves multiple levels, adding new plumbing fixtures to suspended floors can require:
🔩 Core drilling for new pipes
🔥 Fire collars for fire-rated penetrations
🚨 Core drilling and fire collars can add up quickly—if the renovation includes multiple new WCs, floor wastes, or fixtures, these costs must be accounted for.
Excavation and Hand Digging
In maintenance and renovation jobs, machine access is not always possible. Be aware of:
⛏ Hand digging requirements in tight spaces
🏗 Access limitations for excavation equipment
If a section of the job cannot be reached by a machine, make sure your estimate includes labor hours for manual excavation.
Why Accurate Estimating Matters
Renovation and maintenance projects often come with unexpected site conditions. A well-prepared estimate helps plumbing contractors:
✅ Stay within budget
✅ Avoid underquoting costly tasks
✅ Ensure all critical work is accounted for upfront
