As RICS Chartered Surveyors working across Dover and South East Kent, we regularly inspect 1930s homes. Below, we explain the most common issues found during building surveys in Dover.
1930s houses are some of the most popular properties in Dover. They offer generous room sizes, bay windows, solid construction and traditional character. Many buyers are drawn to their space and layout compared to newer homes.
However, while 1930s properties were well built for their time, they are now approaching 90–100 years old. Age alone means certain elements will require attention. If you are buying a 1930s house in Dover, a professional building survey is essential to understand the condition of the property before you commit.
Why 1930s Homes Are Popular in Dover
Dover has a strong supply of 1930s semi-detached and detached houses, particularly in established residential areas. These properties were typically built with:
- Solid brick external walls
- Timber suspended ground floors
- Pitched tiled roofs
- Generous plot sizes
- Traditional cavity wall construction (often without insulation)
Many have since been extended or altered, and some have undergone partial refurbishment. While they are generally robust buildings, age and coastal exposure can introduce risks.
Homes closer to the seafront or elevated positions may also be more exposed to wind and salt air, which can accelerate deterioration of certain materials.
1. Roof Coverings and Structure
Original 1930s roofs were commonly finished in clay tiles or concrete interlocking tiles. Over time, these can deteriorate, slip or crack.
During a survey, we often identify:
- Worn or brittle roof tiles
- Mortar degradation to ridge tiles
- Deteriorated lead flashing
- Ageing underfelt (if original, it may be at the end of its lifespan)
Timber roof structures can also show signs of historic leaks or woodworm activity. While not always serious, these issues can become costly if left unchecked.
2. Damp and Timber Decay
Damp is one of the most common concerns identified during building surveys in dover.
Typical causes include:
- Bridged damp proof courses
- Raised external ground levels
- Blocked subfloor ventilation
- Defective guttering or downpipes
Many 1930s properties have suspended timber ground floors. If ventilation beneath the floor is restricted, moisture can accumulate and cause timber decay. In coastal locations such as Dover, higher humidity levels can increase this risk.
A detailed building survey will assess ventilation, moisture levels and any signs of decay, helping you understand whether remedial work is required.
3. Cavity Wall Issues
Although many 1930s homes were built with cavity walls, insulation was not originally installed. Some properties have since had cavity wall insulation added.
While insulation can improve energy performance, poorly installed systems can introduce damp bridging or cold spots. In exposed coastal environments, driving rain penetration can also affect external walls.
A survey will assess the condition of the brickwork, mortar joints and any visible signs of moisture ingress.
4. Structural Movement
Most 1930s homes are structurally sound. However, minor cracking is common due to:
- Thermal movement
- Settlement over time
- Changes following extensions
In Dover, local ground conditions and sloping sites may contribute to movement in some areas. It is important to distinguish between historic, stable cracking and signs of ongoing structural movement.
A Level 3 Building Survey provides detailed commentary on cracking patterns and whether further investigation is required.
5. Outdated Electrical and Plumbing Systems
Many 1930s houses have undergone partial modernisation. However, surveys often identify:
- Ageing consumer units
- Mixed wiring standards
- Outdated plumbing systems
- Original lead pipework (in some cases)
These may not be immediately dangerous, but they could require rewiring to meet modern standards.
A building survey does not test services, but will highlight visible concerns and recommend further specialist inspection where appropriate.
6. Asbestos-Containing Materials
Some later refurbishments (particularly mid-20th century alterations) may have introduced asbestos-containing materials.
Common locations include:
- Garage roofs
- Textured ceiling coatings
- Soffits and rainwater goods
If suspected, the survey will recommend further specialist testing.
7. Alterations and Extensions
Many 1930s homes in Dover have been extended — often with rear kitchen extensions or loft conversions.
Common concerns include:
- Poor integration between original and new structures
- Inadequate structural support
- Insufficient ventilation to roof conversions
- Lack of Building Regulations approval
A detailed survey will assess the visible quality of alterations and advise where documentation should be verified.
Why a Survey Matters Before You Exchange Contracts
Even if a 1930s house appears well presented, cosmetic improvements can sometimes conceal underlying issues.
A professional survey provides:
- Clarity on condition
- An understanding of repair priorities
- Advice on future maintenance
- Potential leverage for renegotiation
Importantly, it allows you to proceed with confidence rather than uncertainty.
Which Survey Is Suitable for a 1930s House in Dover?
For most 1930s properties, we recommend a RICS Level 3 Building Survey. This provides:
- A comprehensive inspection
- Detailed analysis of defects
- Repair advice and likely causes
- Consideration of alterations and structural elements
For properties in good condition with no significant alterations, a Level 2 Home Survey may be suitable, but older homes often benefit from the additional detail provided by a Level 3 report.
