How should I go about replacing my very old garage?

Answered

I would like to replace my old garage (20 ft x 28 ft) with a storage shed/work shop and carport but too expensive for now. Would like to build or buy a 10 ft x 10 ft shed then tear down old garage (sill plates destroyed by moisture and concrete floor has crumbled apart over time). It would cost about $3000.00 CDN for the new shed. About $35,000.00 for contractor to tear down garage and build storage shed and carport.

Suggestions would be appreciated.


Regards, John

    Hi John there is a lot you can do here yourself. If your willing to do the manual labor of tearing down the old and hauling it off you could save a bundle!

    Can't you just use a corner of the current building?

      That is one possibility I have pondered. I want to reduce the size anyways.


      Thanks!

    If you are a handy person, I would DIY the structure. However, 10x10 is rather tight so you may want to take a can of spray paint and draw it on the grass. Then see how much stuff you can put in that space before committing to it.

    You mean I will have to move the stuff twice? Just kidding! Still a good idea. I just need a place for the lawn tractor and other miscellaneous equipment. Anything else will sit outside or in plastic containers for the winter.


    Thanks!

    In addition to all the great ideas above, there’s some infrastructure challenges that need to be addressed, no matter what you do.

    1.) Rain water run-off and drainage. The sole plates & siding deteriorated because of water damage. Current US Building Codes require the siding to be 8” above the ground with a concrete stem wall - for a stick-built garage. The slab also should be 4” above grade with a 1/2% slope minimum.

    Whatever you do, it’s time for downspouts & trenching around the pad, to take water 10’ away from there.

    2.) Crumbling pad may be due the water percolating through the slab causing efflorescence and spalling. If it has re-bar or welded-wire mesh in it, they are now rusting & will continue to destroy the pad. If it’s caused from high sulphur content in the sand that was used, it will also continue to decay.

    Depending on how bad this is, it may not be able to be stabilized and if one were to pour 2-3” top coat, then it’s going to require more research first.

    Like the person above stated (and has been stating on everyone elses post regarding DIY outdoor sheds...) yes there are codes IF required per your city...personally I would salvage as much of it as possible, reinforce all areas that show any rot or damage (of course replace the too far gone stuff) add additional foundation support, and maybe even line interior with pallets , just to improve the overall structure in case of bad wind, weather issues. This kind of project is my fave! I love taking something with decent bones and giving it life again. The labor will be there but at least you have a frame already and with some spit and elbow grease this could be amazing!
