Replacing vs Reinforcing a Broken Floor Truss in an Existing House

Replacing vs Reinforcing a Broken Floor Truss in an Existing House
  • Opening Intro -

    A damaged floor truss can lead to serious structural problems in your home.

    You may notice these issues immediately or they may occur more gradually over time, but the problems will come.


The damage to the truss may be caused by weight stress, construction error, age, termites, or other factors, but it should be repaired or replaced as soon as you become aware of it. Here are some pros and cons to consider when you’re deciding whether to replace or reinforce the damaged truss.


If you have construction experience or knowledge with floor trusses as well as the necessary tools and equipment, you may be able to do the repair. You will likely need an assistant or two, and it is important to take all necessary safety precautions.

However, replacing a floor truss is a major job, so you may need to hire a professional to do the work if you don’t already have the necessary skills and tools.

Completely replacing the truss is a bigger job, and you should probably hire a professional to handle it.


A repair of this magnitude could take time, depending on your availability. With one or more helpers, you could get it done in a day or so.

On the other hand, even if you have the ability and equipment to repair the truss, you may not have time to do the job quickly.

The workload will increase if you decide to replace the floor truss. Hiring experts can save time because they know exactly what to do and will come prepared to work efficiently.

If you already have a full-time job or a busy schedule, taking on either project yourself can lead to a long repair that drags on for days or weeks, leaving your home’s structure vulnerable for that time and potentially difficult to navigate, depending on where the issue is in your home.


A floor truss repair won’t likely cost as much as replacing it. If you have a contractor’s discount, you can get decent material prices. But floor truss experts may have even better connections with the supply chain to pay less for the materials, especially if equipment is needed to replace the truss.

      some key repair tool ideas to consider      

While it is cheaper to make the repair, you should weigh that against the condition of the other trusses to decide whether a major repair or replacement will be needed soon. If so, it might save time and money to repair the truss now and plan for a more expansive replacement later as other trusses begin to wear out.


Repairing a floor truss is probably going to be less stressful than replacing it in the short-term at least. Replacing a floor truss is a demanding job but usually manageable if you know how to do it.

Replacing the truss could cause stress and anxiety if something goes wrong or you aren’t quite sure how to fix it. However, simply patching up the truss could lead to stress down the road if the repair fails.

other valuable tips:

Compare your options to decide whether to replace or repair a broken floor truss. A simple repair may be manageable, but could lead to more repairs in the future. Alternatively, replacing the floor truss might cost more and require extended time, but could lead to fewer worries about future structural damage.
