Projects
Start practically
Each project combines quantities, work sequence, budget, materials, prices and caution thresholds.
Drywall a room
Estimate drywall sheets from wall dimensions, openings and cuts. Check framing, joint details and applicable fire-resistance requirements.
Difficulty: ●●●●○Install solid hardwood
Estimate hardwood flooring and cutting waste. Check the wood's moisture, subfloor flatness and approved fastening method.
Difficulty: ●●●●○Compare windows by U-factor and energy rating
Compare windows using U-factor, energy rating, air leakage and climate. Consider flashing and installation quality as well.
Difficulty: ●●●○○Add attic insulation
Estimate attic insulation from area, thickness and product type. Inspect moisture, air sealing and ventilation before adding insulation.
Difficulty: ●●●●○Estimate an asphalt shingle roof
Estimate roof area from plan dimensions and pitch, then shingle bundles and offcuts. Evaluate roof decking, flashing and fall protection separately.
Difficulty: ●●●●●Your local file
