Estimate for a Porch rebuild
« on: April 30, 2015, 12:52:58 PM »
My wife and I recently purchased a 2 story multi-unit building in Chicago. We had water damages on the support posts in the back porch and some of the things are not up to code. We have called a few contractors to take a look at the porch. This is an estimate of one of the better ones we like. We've never had this work done so I wanted to poll someone with more experience to see if this is around what it should cost. Originally, our porch is enclosed with vinyl panel siding. This contractor gave an estimate for both enclosed and an open porch. Does this amount look reasonable?

Build new enclosed porch with roof using Pressure Treated wood, according to the architectural plans. All materials will meet City of Chicago building code for the construction of new porch:

**ENCLOSED Porch Estimate**

  • 1. Secure all doors from apartments/house to the porch.
    2. Demo existing enclosed porch with roof and haul away all debris
    3. Install two(2) new concrete foundations 42 deep.
    4. Install 6x6 posts for each concrete foundation
    5. Install ledger beam for first and second floor deck; anchor them with galvanized 5/8 Dia. Lag Bolts with Washers, at 3 1/2 CTS predrilled Dia. holes.
    6. For all column/beam connections install galvanized Dia. Lag Screw with washer (predrill 5/16 Dia. hole)
    7. Install 2x8 joists.
    8. Install 5/4x6 decking over entire floor joist areas.
    9. Install new stair system from the ground to the second floor.

    16. Install new galvanized gutters and downspouts.

    18. Electric works and electric permits are not included in the price. We will remove existing wiring (electric, telephone, TV cable and others) and if we are able we will reinstall into the new porch. We do not guarantee that all reattached cables/wires, are in working condition.

You don't give sq. ft. dimensions but frankly it sounds reasonable.  I do design/build in the PNW but rates vary from area to area.

For the ledgers, be sure they are flashed to prevent water getting into the building frame, this is one of the #1 causes of problems with add-ons.
