We have a combined demolition and framing crew.  This is the best way of getting your second storey up. Fighting the elements (rain and snow) is mission number #1.  It is a little tricky to keep the inside of your home dry - as weather can be unpredictable. Perhaps your basement is already finished and we don't want to damage anything. When removing your roof, we tarp everything on a daily basis to make sure, your home isn't exposed to rain. We want to get the demo and framing done as quickly as possible. We can then get shingles up on your new roof and windows up to weather proof your new home.   During the first few weeks of the project, we will also do any required structural work ( e.g. new concrete pads in basement).  We can typically achieve this in less than 4 weeks.  Demo, Framing, Shingles and windows!
