    Hello,

    I have a proposal submitted to a client for a small patio/landing off of a sliding glass door at the back of the house that will step down to the patio.

    My question is, what kind of construction details do I need to consider having a landing built againt the house that is going to be filled with stone. I was planning on using techo block to construct the landing with a paver area that will be about flush with the bottom of the sliding door sill. It will only have one step between the top and the patio.

    I am figuring it as a deck, needing a moisture barrier to protect the rim joist from the moisture that will be right up against it. Also, some sort of spill guard to keep water from creeping in between the new landing and the house. I will have to remove/trim some vinyl siding to accomdate the landing as it will be wider than the sliding glass door. Currently, there is no siding directly under the door, just bare wood (ther rim joinst) with a 'make shift' staircase the builder installed.

    I have an experienced carpenter to assist me, and give me some advice, but am seeing if there are any other considerations that we may have both missed. I'm also going to to give a call to the town building code office to make sure they don't have any other funny requirements.

    We use solid block along the house keep it about a 1/4" away from the house and replace the wood with pressure treated wood using a good caulk around it.

    Paul,

    when you say solid block, do you mean you set regular building block with mortarted joints along the back edge? Would it be possible/ideal to build a wall out of the techo block with the fae towards the house instead, and then maybe have a plastic liner/fabric lining the inside so moister doesn't seep out over time?

    Also, you say 'replace the wood with pressure treated. I assume you mean attach a piece to the existing rim joinst under the door that is the same width as the joinst, then seal it up.

    Steve, we have solid wall units here made by Versa-lok we turn then in so flat side is along the wall, and yes use treated lumber on anything buried untill you are below foundation wall

    thanks,

    I'm familiar with the solid units. They would probably be the best bet, but techo does not have them in their line.

    Most jobs I've done, I've always had a 'step down from the house' so that the pad is just at the bottom of the sill. I just want to make sure I don't rot these peoples house apart 5 years down the line. I like the idea of having the landing flush with the door so that you don't have to walk out the door and take a 'blind step' so to speak.

    We use V-Lok as well, sounds like a similar process to the one Paul uses. We have no wood at all - we remove any that's against the house, down to the vapor barrier.

    We trim the vinyl and install J-channel around the new siding lines (which is a lot like building a house and then putting in the basement). Requires some finnagling (sp?). Then we put up some aluminum trim coil that either matches or coordinates with the siding. This trim coil (painted sheet aluminum) extends into/beneath the j-channel, meets the door sill, and covers everything down to the foundation. Then it's caulked - all along the j-channel, and over all the nails you used to put up the trim coil. Then the V-Lok block goes in. Once the perimeter or 'frame' is built and the interior is filled with block, we sweep sand over everything to fill the voids/grooves/holes in the V-Lok.

    Hello,

    thank you all for the help. I really never thought about building a wall along the back side of the stoop. I already gave them a estimate, but luckily added a nice 'fudge' factor that will easily cover the cost of the extra time and material. I may change it a little bit, but at least I know I am on the right track.



    And fireman, thanks for the tip. I also believe grinnel makes a solid unit also, which is basically the same as the anchor block. Hopefully I can get them though. The solid blocks always seem to be on back order or unavailable. Maybe I can get some color rejects for a good price at the factory though.

    Steveair,

    I see we're not too far from each other and I am giving a proposal for the same type of job. That house wouldn't happen to be in Wayne would it?

    Henry,

    no, the job is in Flanders. It would be funny though to find out two people here on lawnsite are bidding on the same job. We may have to have a 'clause' in the rules and reg section to prevent this type of thing:) I bet, in the future, its bound to happen eventually.

    I actually am bidding against a company called 'harolds landscaping' down there. The homeowner said my drawing/plan blew them away, as they only had a hand drawn sketch on grid paper. My pricing was about the same, maybe even a little more, but they were impressed by the drawing. They are a much larger company than me, lots of fancy trucks/machines, lots of help. It always makes me feel good to go head to head with the big boys and get the job.

    Say, I just got an estimate to look at a walkway/patio up in bloomingdale/kinnelon. Thats up in your area. Haven't been any jobs out like that in the last week have you?
