rotted sill...how to replace?

Question

I've got a problem that may be unique,A two foot section of house sill is decayed and is now gone completely- located under the front concrete steps.  Access from the basement isdifficult between the rafters but can clearly see the hole with theinsulation removed in this area.I may have access thru a hole in the sidewall of the concrete steps.Am not sure how big I can make the hole in the sidewall (there are 3steps).Solution......I don't see how I can scarf in a replacement piece ofwood due to poor access. Maybe fill with concrete somehow?Suggestions?.........thanks in advance.DHill

first fix the grade, dirt laying against wood even PT wood over timeis a bad idea, espically in a structura situation.first remove steps, regrade area, replace sill, then replace steps

Greetings,If it isn't causing a problem putting some concrete there and waitinguntil things get worse (which might never happen or you might sell thehouse) isn't such a bad idea.Hope this helps,William

I'd replace the sill from the basement. I'd place a length of 4x4 (4 foot,

6 foot long, preferably longer that the area of sill you need to replace) along the floor joists, lift *slightly* with floor jacks at each end of the 4x4. Use a sawzall to cut the nails and cut out the rotted section of wood. Replace with treated 2x6 material and sill gasket, seal it good with caulk at the ends. You also might want to investigate as to root cause of the rotted sill. (termites, water damage, etc.)
