Deck Builder by HBS

Deck Builder by HBS helps contractors and DIY builders turn deck dimensions into material lists, cut plans and customer estimates. PLAN YOUR DECK Choose rectangular, L-shaped or U-shaped layouts. Select decking sizes, board direction, staggered layouts, breaker boards and picture-frame borders. CALCULATE MATERIALS Generate decking and framing cut lists, stock purchase quantities, screw packages and joist bracket quantities. Customize prices to match your supplier. LAY OUT RAILINGS AND STAIRS Calculate railing materials from selected deck sides, deduct stair openings and include stair railings. Enter baluster width and your desired gap to get equal spacing and on-center marking positions. The custom stringer guide includes rise/run settings, tread-thickness adjustment, blank lengths and marking instructions. CREATE AND SHARE ESTIMATES Save customers and estimates on your iPhone. Share customer estimate PDFs, or export separate contractor PDFs and CSV material/cut lists. WORK OFFLINE No account or subscription required. Export and import backups to protect your records. IMPORTANT Deck Builder is an estimating and layout tool, not an engineered design or permit approval. Verify applicable codes, structural details, connections, footing requirements and final measurements. Included prices are editable examples; confirm local pricing before quoting or ordering.
