Remodeling? Don’t Let Plumbing Be an Afterthought

Home renovations are exciting — but they also expose what’s hidden behind the walls. Plumbing is one of the most overlooked elements in remodeling projects, and poor planning can quickly lead to budget overruns, delays, and code violations.

Here are five common plumbing issues we encounter in Massachusetts remodels — and how to avoid them from day one.


1. Undiscovered Pipe Damage

Old homes often have hidden problems like corroded pipes, outdated materials (like galvanized steel), or small leaks. Once you open walls or floors, surprises happen.

How to avoid:
Always have a licensed plumber do a pre-remodel inspection. It helps you budget realistically and avoid emergency fixes mid-project.


2. Inadequate Water Pressure After Upgrades

Adding a bathroom or luxury fixtures like rain showers? The existing plumbing may not be sized properly to handle the new demand, resulting in weak water pressure or performance issues.

How to avoid:
Consult a plumber during the planning phase to evaluate pipe sizing and pressure capacity before committing to fixture upgrades.


3. Poor Drainage Planning

Incorrect slope, long horizontal runs, or improper venting can lead to slow drains or even sewer smells after the remodel is complete.

How to avoid:
Work with a plumber who understands code-compliant layout and venting. For larger homes or additions, systems like ProVent can help reduce complexity.


4. Overloaded Water Heaters

After a kitchen or bathroom addition, your existing water heater may be undersized for the new demand — especially if it’s more than 10 years old.

How to avoid:
Have a plumber calculate total hot water needs. Consider upgrading to a tankless system for energy efficiency and space-saving.


5. DIY or Unlicensed Work

Many delays happen because of non-compliant plumbing installed by handymen or homeowners. This can lead to failed inspections, tear-outs, or worse — leaks inside finished walls.

How to avoid:
Only hire licensed plumbing contractors familiar with Massachusetts code. It saves time, money, and stress in the long run.
