How to Repair a Rotted Windowsill | Without Removing Window

In this DIY video, I show you a cheap and easy way to repair a rotten area of a window sill. This video shows how to cut out and repair a rotten section on the exterior side of the window, without having to take out and remove a window.

I was waiting for the glass to break (and it didn't) good job Dave.

Looks good. To add more life to the repair its always good to primer paint the exposed cut edge of the original sill and then smear some silicon/silastic . Let that cure a bit then nail on the plastic flashing and fit new timber to it. This will add many years to the repair. The other thing is those bushes need cutting back to create more ventilation and sun exposure. Great job and thanks for sharing.

Surely he primed the cut, surely. That's 101

[@loganmalthus6402]

Looks great but I agree, I also think there should’ve been a slight fall to the sill. To prevent moisture buildup

[@DaveDoesCarpentry]

Cheers for the comment. I did spray the ripped part of the timber with eco seal, something I’ve always done when cutting treated timber, which I should have included in the video.

@loganmalthus6402 Thanks, there is a slight fall, I actually did film a part testing it with water and talking about the importance of the water run off while I was putting the window packers in to support it, but the camera was out of focus for that part and I forgot to leave a note in the video. Cheers for bringing it up with your comment. Bit of information for anyone doing this job: when I cut the exisiting sill with the multi tool, the blade was on a slight angle to make sure I didn’t hit the glass. This means the exisiting window sill has a small angle, and when I screwed the new piece on, that angle created the fall and the new piece sloped down away from the window.

@@DaveDoesCarpentry that was a pain in the butt job and you did really well to make it look halve decent. A bit like doing a love job for a family member or mate after it got rejected by trade guys or handyman and then Dave gets a call and couldn't say no. Keep up the good work and I'm sure that the video editing takes a lot of time and they continue to get better.👍

I use T rex. It’s flexible and bonds better than liquid nails for exterior … liquid nails goes brittle. Plus it’s sealing at the same time. U can thin out with acetone and rag while taped up for a clean line however only wipe once singular direction. And re wipe with new section of rag with acetone.

Great video. A Tip. Try to talk slow because I find sometimes I have to watch some parts again and again because you seem to talk too fast. I love your videos and hopefully you start a podcast kind of series too.

Are you Australian? Because I can understand him

[@jakevee3319]

That’s a neat job, only big mistake iv seen is gluing the quads onto the window, makes replacing those bottoms windows way harder than it needs to be

[@xHenro]

Multi tool is also called a renovator because it was a popular brand that old fellas used called renovator

[@Simon-Simon-Simon]

Putty ? Epoxy but we in Australia don't have it freely like UK

[@HerbaceousM8]

[@marcussomerville]

Hikoki tools rock! nice work!

[@zacschneider1035]

Hey Dave, not sure what's going on but I got unsubscribed from you. Just resubscribed. Weird.

[@DaveDoesCarpentry]

That’s weird as. Thanks mate!

[@ching574]

instead of doing all that you could have just used wood epoxy it stops the rot seals the wood and is sandable would have saved you a lot of work and would have been done by the time you where done cutting if that

[@U.s.e.r.3493]

Agreed, but suppose not exactly carpentry....

[@sydney8382]

replacing the whole thing is the proper way mate, you clown

Hi Dave . I regularly watch your videos. They are very informative. Would you be able to make a video on marking a slab for a stick build . From start to finish . Thanks in advance .

[@MyOathCobLoaf]

Agree with the slab flick out video👍🏻

[@DaveDoesCarpentry]

Of course! I actually filmed that exact video about 2 weeks ago but I didn’t do a great job at explaining everything so I will re do it in a few weeks!

[@kamalthakur2040]

@@DaveDoesCarpentry Hi Dave . Thanks for your reply . I am a site supervisor and have asked a couple of times our framing crew. Answer is always we are too busy . I will really appreciate if you can start from the very beginning when you arrive onsite, reading the floor plans and start explaining what to check , how you mark the bottom plates etc. I am sure there are a lot of site supervisors they are eager to learn. Regards
