The Most Common Issues Found in Hertfordshire Homes (and How a Survey Protects You)

Buying a home in Hertfordshire is exciting — but the county’s rich mix of property types comes with its own quirks. From Victorian terraces to 1930s semis and 1960s/70s family homes, each era carries its own pattern of defects that buyers should be aware of.

At ClearView Home Surveys, we inspect hundreds of properties across Hertford, Ware, Broxbourne, Bishop’s Stortford, and the surrounding areas, and the same issues appear time and time again.

Below, we break down the most common problems — and how a good survey protects you from unexpected repair bills.

1. Damp & Moisture Penetration

Damp is easily one of the most frequent issues we find across Hertfordshire. It appears in many forms:

  • Rising damp in older brickwork

  • Penetrating damp from defective pointing or cracked render

  • Condensation from poor ventilation

  • Blocked gutters causing water to run down external walls

Victorian terraces in Hertford and Ware are particularly prone, as they often lack a modern damp-proof course and have solid brick walls that absorb moisture.

Why it matters:

Damp can lead to timber decay, mould growth, and expensive remedial works.

How a survey helps:

We use moisture readings, visual checks, and condition ratings to determine the cause and severity — not just the symptoms.

2. Roof Issues (Especially on 1930s & Mid-Century Homes)

Roof problems are extremely common, especially on:

  • 1930s clay-tiled roofs

  • 1950s–1970s concrete tiles

  • Older slate roofs

Typical defects include:

  • Missing, cracked or slipped tiles

  • Failing underlay

  • Poor ventilation in the loft

  • Deteriorated flashings around chimneys and valleys

  • Moss build-up trapping moisture

Many homeowners have no idea the roof is nearing end-of-life until a survey reveals it.

Why it matters:

Roof replacements can run into thousands — and leaks cause secondary damage internally.

3. Outdated Electrical Installations

Many Hertfordshire homes still have:

  • 30+ year old fuse boards

  • No RCD protection

  • Outdated wiring

  • Limited socket provision

  • DIY electrical alterations

Even “modern-looking” homes in estates around Hertford and Broxbourne often have untouched original electrics from the 1980s–1990s.

Why it matters:

Electrical safety is crucial. Mortgage lenders often question outdated installations.

How a survey helps:

We identify visible safety risks and advise when to obtain an electrical inspection.

4. Poor Loft Insulation & Lack of Ventilation

Energy efficiency issues are extremely common, including:

  • Thin or missing insulation

  • Blocked eaves vents

  • Condensation on roofing felt

  • Inadequate airflow causing mould within the loft

This is especially noticeable in older homes and those that have had loft conversions without proper ventilation strategies.

Why it matters:

Poor insulation = higher heating bills.

Poor ventilation = decay, damp, and unhealthy living conditions.

5. Structural Movement

Many homes in North and East Hertfordshire are built on clay subsoil, which is prone to shrinkage and expansion — especially during hot or dry summers.

Common concerns include:

  • Cracks around windows and doors

  • Out-of-plumb walls

  • Distortion in floors

  • Settlement around extensions

Not all movement is serious — but identifying whether it is historic or ongoing is vital.

How a survey helps:

We assess crack patterns, historic repairs, and risk factors to help you understand whether specialist advice is needed.

6. Inadequate or Poorly Built Extensions

Hertfordshire properties — especially 1930s semis and 1960s houses — often have single-storey rear extensions, loft conversions, or garage conversions.

We frequently identify:

  • Lack of building regulation approval

  • Poor insulation

  • Unsupported chimney breasts

  • Structural alterations without certification

  • Poor workmanship hidden behind finishes

Why it matters:

You inherit responsibility for any non-compliant or unsafe work.

7. Windows, External Joinery & Timber Decay

Timber windows and fascias in older homes often suffer from:

  • Rot

  • Flaking paint

  • Failed seals

  • Warping

Even uPVC windows can fail if poorly installed or very old.

Why it matters:

Window replacement or repair can significantly impact your budget.

8. Drainage & Gutter Problems

Another extremely common defect — often overlooked.

We commonly find:

  • Blocked gutters

  • Leaking downpipes

  • Poor surface drainage

  • Blocked or broken below-ground drains

Left unchecked, drainage issues lead to damp and foundation movement.
