How to repair a rotten front beam?

[rrawal]

Hello everyone,

We have a front beam on our property that has developed rot along approximately the last 15 cm at one end. The rest of the beam—spanning around 5 to 6 metres—appears to be in good condition. Fortunately, the beam is already well supported by metal pillars positioned in the middle.

To reinforce the affected area, we’re considering installing a metal bracket (as shown in the attached figure) to provide extra support and prevent further deterioration or structural risk. We’ve explored the option of replacing the entire beam, but this would be a costly undertaking. It would require roof scaffolding and extensive work for what seems to be a relatively localised issue.

We’d love to hear your thoughts:

• Is adding a bracket a sensible and safe solution?
• Are there better or more effective alternatives for reinforcing the beam?
• Has anyone here dealt with a similar situation?
• Any advice, suggestions, or even a bit of reassurance would be greatly appreciated!

Thanks in advance.

Hello @rrawal 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about the front beam of your house.

The damage appears to be semi extensive as one end appears to have rotted, and the rainwater appears to have travelled inside and has rotted the top section of the beam.

I propose taking that next step and getting a quote from three different builders and see which one offers the best possible value for the money. Placing the bracket is mostly a band aid solution, it will not offer a long term- fix and the rot and damage will continue to creep along the entire beam.

I believe the source of the leak might be coming from faulty flashing, gutter overflow or damage to your roof line that is allowing water to bridge inside the beam. I recommend addressing any possible leaks first before you carry out any rebuilding efforts. 

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendation.

If you need further assistance, please let us know.

Good Afternoon @rrawal 

The issue appears to be resonably large. Its not just a matter of a bracket supporting the end of the beam (The rot has weakend that whole end of the beam so supporting it really wont be an answer) The beam looks like it goes into the brickwork and sits there supported by the wall. This would also stop forward movent of the weight of those tiles towards the front of the yard by locking the roof into place.

I would also recommend to get a few builders quotes to replace and fix the water issue that has caused teh timber to rot in the first place. The roof will need ag prop supports while you repair the issue. It may also be an idea to investigate the eves around the location as well. Mostly due to the age of the property and if there is one section rotting it doisnt hurt to check others.

Hi @rrawal 

This is a common issue I deal with regularly. The extent of the rotted end is fairly large and on the board of a full replacement. However a new section can be "spliced" in after the rotted section has been completely removed.

Both @Dave-1 and @EricL advice on getting a few quotes from builders though is sound, in reality the job is to small for them. A decent handyman service can do the repair. And again get a couple of quotes and check reviews and compare their method of repair. If in doubt, should that info our way for review.

Dear Nailbag, Eric and Dave, 

Thank you for taking the time to respond and offer your insights on this issue.

We’ve identified the source of the water leak—it appears to be due to misplaced flashing. We are in the process of engaging a roofer to replace the entire roof and flashing, so we’re hopeful that this will resolve the problem.

We also appreciate your suggestions regarding the inspection of the eaves and obtaining quotes from builders and handymen. In particular, we found the idea of splicing the timber for additional support to be very useful.

Thanks again for your time and assistance.

Best regards,

RRawal

Good Morning @rrawal 

If you are considering splicing the timber above the steps I would definently consider a carpenter for the job. I have done a few splices over the years and while they are solid, they may not look the type of perfect you want to have at your entrence way A carpenter (check their other work before engaging them) will be able to have a seemless look and will also have access to ag props to support that section while replacing it.
