SheetFlow vs HB Construction Calculator

SheetFlow is the modern, offline-first drywall and plasterboard material estimator designed for drywall contractors, home builders, DIY renovators, and construction estimators. Ditch the messy notebooks, buggy calculation sites, and outdated spreadsheet templates. Whether you are remodeling a home basement in the US or plastering a residential extension in the UK, SheetFlow calculates your drywall sheets, joint compound, fasteners, joint tape, and labor rates in seconds. LOCALIZED FOR US (IMPERIAL) AND UK (METRIC) SheetFlow dynamically localizes all terms and metrics to fit your local construction job standards. Instantly toggle between: - US Mode: Calculates in feet/inches, "Drywall" boards, standard sheet sizes (4x8, 4x10, 4x12), joint mud compound in gallons, coarse screws in pounds (lbs), and applies US Sales Tax. - UK Mode: Calculates in meters, "Plasterboard" sheets, metric board sizes (1.2m x 2.4m, 1.2m x 3.0m), joint compound tubs in kilograms (kg), screw boxes, and applies UK VAT rates. SMART MULTI-ROOM AGGREGATION Most calculator apps only allow you to estimate one room at a time. SheetFlow allows you to map out an entire residential project in a single quote: 1. Log individual rooms (e.g. Master Bedroom, Kitchen, Basement) with custom length, width, and ceiling height dimensions. 2. Toggle whether to include the ceiling area for each specific room. 3. Automatically deduct window and door cutouts to prevent material over-ordering. 4. Review the Master Materials report showing the total combined materials required for the entire building job. ITEMIZED LABOR & COST ESTIMATES Budget your building projects accurately by estimating labor services alongside material costs: - Toggle between flat project fees or per-sheet/per-board installation rates. - Customize local material unit pricing for boards, joint compound buckets, screws, and tape. - Review an itemized project billing invoice showing exact subtotals, tax (Sales Tax or VAT), labor services, and the final grand total. OFFLINE-FIRST HISTORY LOGGING Keep your contractor files organized on the go. SheetFlow stores all quotes locally on your device: - Review project statistics including total jobs, logged rooms, and cumulative estimated costs. - Quickly search, filter by region (US vs UK), and select previous quotes. - Load historical estimates back into the calculator to edit dimensions or update pricing rates. PRO PROFESSIONAL FEATURES SheetFlow offers a simulated sandbox to preview Pro-tier contractor utilities: - Limitless room additions: log as many rooms as your job site demands. - Export printable reports: print physical invoice sheets or save PDF quotes to share with clients via email or message. - Ad-free, private, and 100% offline-ready. Build smarter, order faster, and estimate accurately with SheetFlow.
