Understanding Structural Issues in Period Properties
Older properties around Brighton and Hove possess unique charm and character, but they also come with structural challenges that modern homes don't face. Built using traditional construction methods and materials different from today's standards, Victorian and Edwardian houses throughout Sussex require expert assessment from chartered building surveyors who understand period property construction.
Our comprehensive Level 3 building surveys identify structural defects in older properties across Brighton, helping buyers understand repair requirements and costs before purchase. This guide explains what our RICS surveyors look for when assessing period properties throughout the Brighton area.
Most Common Structural Issues in Brighton's Older Properties
1. Foundation Movement and Settlement
Older properties in Brighton were often built on shallow foundations—sometimes just brick footings 18 inches deep, compared to modern requirements of 3+ feet. This makes them vulnerable to movement.
Warning Signs:
- Diagonal cracks wider than 3mm at corners
- Cracks following mortar joints in a stepped pattern
- Doors and windows sticking or not closing properly
- Gaps between walls and ceilings or floors
- Tilting or leaning walls
Brighton Context: Properties on clay soils around Hove and Preston Park are particularly prone to movement due to seasonal moisture changes. Our chartered surveyors' building surveys identify whether movement is historic (stabilized) or ongoing (requiring intervention) throughout Sussex properties.
Repair Costs: Minor repointing and crack repairs: £1,000-£3,000. Underpinning for significant foundation issues: £10,000-£50,000+ depending on extent.
2. Subsidence, Settlement, and Heave
These three forms of ground movement affect older properties differently:
Subsidence: Downward movement as ground beneath foundations sinks or shrinks. Common causes include tree roots extracting moisture from clay soils, leaking drains washing away supporting ground, and drought conditions shrinking clay.
Settlement: Natural compression of ground under a building's weight. Usually occurs early in a building's life and stabilizes. Less concerning than subsidence.
Heave: Upward ground movement as clay soils expand when moisture increases. Often happens after trees are removed near properties in Brighton.
Our RICS surveyors' comprehensive surveys distinguish between these movement types, assessing severity and recommending appropriate action for properties throughout the Brighton area.
3. Wall Tie Failure
Victorian properties with cavity walls (common from 1880s onward) used metal wall ties connecting inner and outer wall leaves. After 100+ years, these corrode, causing:
- Horizontal cracking in brickwork at wall tie levels
- Bulging or bowing external walls
- Separation between wall leaves
Brighton Example: We regularly identify wall tie corrosion in Victorian terraces around Hanover and Kemp Town. Our Level 3 building surveys note wall tie condition, recommending replacement when necessary.
Repair Costs: Wall tie replacement for a typical terraced house: £3,000-£8,000. Includes installing new stainless steel ties and making good brickwork throughout Sussex properties.
4. Timber Decay and Rot
Older properties rely heavily on structural timbers—floor joists, roof timbers, lintels—susceptible to rot when exposed to moisture.
Wet Rot: Affects timber with high moisture content (above 20%). Causes timber to darken, crack, and lose strength. Addressing the moisture source usually stops wet rot.
Dry Rot: More serious fungal decay that can spread through masonry to attack other timbers. Requires extensive treatment including removing all affected timber plus a 1-meter margin.
Our chartered building surveyors test suspicious timbers using moisture meters and probes during comprehensive surveys of properties around Brighton. We identify rot risks from poor ventilation, leaking plumbing, or failed damp-proof courses throughout the Brighton area.
Repair Costs: Treating localized wet rot: £500-£2,000. Extensive dry rot treatment with timber replacement: £5,000-£20,000+.
5. Roof Structure Problems
Victorian and Edwardian roofs in Brighton properties commonly feature:
- Roof spread: Rafters pushing outward where roof structure lacks proper ties or support
- Sagging ridge: Central roof beam dropping due to inadequate support
- Rafter decay: Timber rot at rafter ends where they meet walls
- Missing or broken tiles: Leading to water ingress and further decay
Our RICS surveyors inspect roof voids thoroughly during building surveys, identifying structural defects before they become major problems for properties throughout Sussex.
Repair Costs: Roof re-tiling: £5,000-£12,000. Structural repairs with new supporting timbers: £8,000-£20,000. Complete re-roof: £15,000-£40,000+.
6. Lintel Failure
Older properties around Brighton often have timber lintels above windows and doors. After decades, these can rot, crack, or fail, causing:
- Cracking above window and door openings
- Dropped lintels creating gaps
- Sagging brickwork or masonry arch distortion
Our comprehensive surveys identify lintel conditions throughout Brighton properties, recommending replacement before failure occurs.
Repair Costs: Replacing individual lintels: £400-£1,200 each. Multiple lintel replacement in terraced houses: £3,000-£8,000.
7. Chimney Stack Issues
Most older properties in Brighton have chimney stacks—tall, heavy structures vulnerable to:
- Leaning or tilting due to foundation movement
- Cracked or deteriorated flaunching (mortar around chimney pots)
- Missing or damaged chimney pots
- Water ingress causing internal damp
- Corbelled brickwork deterioration
Our chartered building surveyors assess chimney stability using binoculars and drone surveys where necessary for properties throughout the Brighton area.
Repair Costs: Repointing and re-flaunching: £800-£2,000. Partial rebuild: £2,500-£6,000. Complete stack removal: £3,000-£8,000.
8. Damp Penetration Through Solid Walls
Pre-1920s properties in Brighton typically have solid brick walls (no cavity) 9 inches thick. These are more vulnerable to penetrating damp than cavity walls, especially on exposed elevations facing prevailing winds and rain.
Our Level 3 building surveys identify damp penetration causes including deteriorated pointing, failed render, blocked or absent gutters, and porous brickwork throughout Sussex properties.
Repair Costs: Comprehensive repointing: £3,000-£8,000 for a terraced house. External render or waterproof coatings: £5,000-£15,000.

Should You Buy an Older Property with Structural Issues?
Discovering structural problems during surveys doesn't automatically mean walking away. Our RICS surveyors help buyers throughout Sussex understand:
- Severity: Is it cosmetic, requiring monitoring, or needing immediate repair?
- Costs: Realistic repair estimates for budgeting
- Urgency: Can repairs wait or must they happen immediately?
- Impact on value: How do defects affect property worth?
Many buyers successfully purchase older properties in Brighton with structural issues, negotiating price reductions or requiring repairs before completion. Our comprehensive building surveys provide evidence for negotiations.
Real Brighton Case Studies
Case Study 1: Victorian Terrace in Hanover
Our Level 3 survey identified diagonal cracking suggesting subsidence related to a large tree in the front garden. The buyer negotiated £15,000 off the asking price, had the tree professionally managed, and monitored movement for 12 months. No further movement occurred—the subsidence had stabilized decades earlier.
Case Study 2: Edwardian House in Hove
Our chartered surveyors found extensive roof spread and sagging ridge requiring structural repairs. Originally quoted £25,000, repairs were completed for £18,000 by inserting steel ties and supporting the ridge. The buyer saved £40,000 on the purchase price—a significant net saving.
Case Study 3: Georgian Property in Brighton
Our building survey revealed dry rot affecting ground floor timbers due to failed damp-proof course. Treatment cost £12,000 including new damp-proof course, timber replacement, and specialist fungicidal treatment. The seller agreed to complete repairs before sale, confirmed by our follow-up inspection.
Frequently Asked Questions
Not necessarily! Our Brighton surveyor team assesses crack severity based on width, location, and pattern. Hairline cracks under 1mm are usually cosmetic. Cracks 1-3mm may require monitoring. Cracks over 3mm—especially diagonal cracks at corners or stepping through brickwork—need investigation by chartered building surveyors. Our comprehensive Level 3 surveys distinguish between historic settlement (common in older properties throughout Brighton) and active movement requiring intervention. Context matters: a 5mm crack in a 150-year-old property might be less concerning than a 2mm crack in a 10-year-old building around Sussex.
Our chartered surveyors recommend budgeting 5-15% of purchase price for repairs and improvements in older properties throughout Brighton and Hove, depending on condition. A £400,000 Victorian terrace might need £20,000-£60,000 over the first few years for roof repairs, damp treatment, window restoration, and modernization. Our detailed Level 3 building surveys provide specific cost estimates for identified defects, helping buyers budget realistically. Properties in poor condition may require 15-25% investment. Well-maintained period homes might need just 2-5%. Commission comprehensive surveys from our RICS surveyors for accurate budgeting across Sussex properties.
Absolutely! Our RICS chartered building surveyors strongly recommend Level 3 surveys for all properties over 100 years old in Brighton. Level 3 surveys are more detailed than Level 2 homebuyer reports, examining structural condition thoroughly. For Victorian, Edwardian, and Georgian properties throughout Sussex, Level 3 surveys identify issues that basic surveys miss—hidden timber decay, structural movement, roof defects, and damp problems. The comprehensive reports include detailed repair specifications and cost estimates. While Level 3 surveys cost £800-£1,500 for typical terraced houses in Brighton, they often save buyers £10,000-£50,000+ through price negotiations or avoiding problematic properties entirely.
It depends on severity. Minor issues like cosmetic cracking rarely affect mortgages for properties in Brighton. Moderate problems may require undertakings to complete repairs within specified timeframes. Serious structural defects—active subsidence, extensive dry rot, dangerous structural instability—can make properties unmortgageable until repairs are completed. Our chartered building surveyors throughout Sussex advise lenders regularly. We clearly indicate in our comprehensive survey reports whether defects are likely to affect mortgage availability. If your chosen property has significant issues, some lenders offer retention mortgages—holding back funds until repairs are completed to satisfactory standards around Brighton and Hove.
Our RICS surveyors recommend monitoring systems for properties with existing cracks or movement in Brighton. Simple tell-tales (glass or plastic strips across cracks) show whether movement continues. Professional monitoring involves crack width measurement at regular intervals. If cracks widen more than 1mm over 12 months, investigation by chartered building surveyors or structural engineers is warranted throughout Sussex. Seasonal movement of 1-2mm is normal in clay areas around Brighton—cracks widen in summer when clay shrinks and close slightly in winter. Continuous unidirectional widening indicates ongoing problems. Our Level 3 building surveys identify cracks requiring monitoring, providing measurement baselines for comparison.
Definitely not! Older properties throughout Brighton offer character, spacious rooms, and solid construction that modern houses often lack. Yes, period properties require more maintenance than new builds, but they also often appreciate better and have proven longevity. Our chartered building surveyors help buyers make informed decisions about older properties across Sussex through comprehensive Level 3 surveys. We identify defects, estimate repair costs, and assess whether issues are manageable or deal-breakers. Many structural problems in Victorian and Edwardian properties are repairable at reasonable cost.
