Crack damage (BRE 251)
Width plus corroborating signs give the category 0–5, damage class and recommended action — including when to fit tell-tales or refer to an engineer.
On-site Assessment Tools
Five standards-based checks, right where you inspect.
Stop switching to a browser mid-inspection. PropertySurvey Pro builds the assessments a surveyor actually makes on site — crack categories, knotweed classification, stair geometry, roof pitch and floor areas — into the Survey Wizard, computed on the device and rendered straight into your report.
From measurement to report wording in one step
Each tool implements the published framework: BRE Digest 251 damage categories with corroborating-factor escalation, the RICS A–D Japanese knotweed assessment, stair geometry limits from Approved Document K and eleven other national codes, roof pitch and rafter trigonometry, and the RICS measurement bases for floor areas. Results appear as standards-referenced paragraphs in the On-site Assessments section of your PDF — and because the inputs are stored on the survey, every assessment stays editable and the wording recomputes when you change a value.
Japanese knotweed (RICS A–D)
Three questions on site, categorised with lending implications and next steps.
Stair geometry, 12 codes
Riser count, actual rise, pitch and 2R+G checked against Approved Doc K, IRC, NBC, NCC, NZBC and more.
Roof pitch & rafter
Pitch in degrees and X-in-12, rafter length with eaves overhang, and the slope factor for true roof area.
Floor areas (RICS bases)
GIA, GEA, NIA or IPMS with deduction rows and automatic square-foot conversion.
Report-ready & editable
Standards-referenced wording in the report preview and PDF, recomputed whenever you edit an input.
Frequently asked questions
Which property inspection app has built-in BRE 251 crack assessment?
PropertySurvey Pro. Enter the crack width and tick the corroborating signs — several cracks, sticking doors, distorted frames — and the app returns the BRE Digest 251 category 0–5 with its damage class and recommended action, from redecoration through tell-tale monitoring to a structural engineer referral.
Can it classify Japanese knotweed?
Yes — three on-site questions (live or treated, within 7 metres of a structure, causing damage) give the RICS A–D category with the lending implications and next steps spelled out, ready for the report.
Which stair regulations does the geometry checker cover?
Twelve national standards: UK Approved Document K (private, utility and general access), the US IRC, NBC Canada, NCC Australia, NZBC D1, NBC India, Singapore BCA and IBC-based Gulf codes. It derives riser count, actual rise, pitch and the 2R+G comfort rule, with a pass/fail on every limit.
What floor-area bases are supported?
GIA, GEA, NIA and IPMS per the RICS measurement codes. Enter dimensions in metres or feet (imperial regions default to feet), flag stairwells and voids as deductions, and get the result in m² and sq ft with the basis recorded in the report wording.
Do the results go into my report?
Yes. Every assessment you include renders as a colour-coded, standards-referenced result in the On-site Assessments section of the report preview and PDF — with an optional surveyor comment you can dictate and AI Polish — and stays editable: change an input and the wording updates everywhere.
Are the tools free?
Yes — all five tools are computed on the device and are free for every user, online or offline.
