Additions & Decks
The tie-in is where additions go wrong
An addition is really two problems: the new structure, which is straightforward, and the seam where it meets the old one, which is not. Roof planes, foundation settlement, and snow shed from the existing roof onto the new one cause almost every addition failure we get called to fix. We design the seam first.
What's included
- Snow-load and snow-shed engineering, not just square footage
- Foundation tie-in matched to how the existing structure has settled
- Roof plane and flashing detailing at the junction, the failure point
- Deck framing and railings to current code, built for the ski-season load
- Permits for your specific jurisdiction, handled by us
What most bids leave out
Ask where the snow coming off your existing roof will land once the addition exists. If the builder has not thought about it, you will discover the answer in February.
Before After ★★★★★
“The addition looks like it was always part of the house. Nobody can find the seam, including me, and I watched them build it.”
Open books, both directions
You see every subcontractor bid, every material invoice, and our fee as a separate line. When a number changes you find out that week, not at the end. Nobody has ever been surprised by a Stonepine invoice, and that is the whole point.
