RICS Level 3 Building Survey Cottered

Cottered’s housing stock brings challenges our inspectors see again and again. Around the village green sit plenty of pre-1919 homes, from thatched cottages to Grade II listed buildings, and they are full of exposed timbers and inglenook fireplaces. Character is not the problem. Hidden defects are. A crack in a 300-year-old wall may be nothing, or it may be the clue that points to urgent structural work, and only a proper inspection will tell the difference.

A recent run of modern eco-friendly homes, including a five-bedroom detached house completed in May 2024, shows how the village has moved on. Those newer builds bring a different set of questions, from building regulation compliance to insulation standards and the quality of modern construction methods. Our Level 3 Survey looks at both ends of the market, from a traditional cottage to a contemporary new build, and checks the property as a whole.

House prices have dropped 44% from their 2023 peak of £790,000, so buyers have more room to negotiate than before. A detailed survey report gives you written evidence of defects, which can support requests for repairs or a price reduction before completion. Our inspectors know Hertfordshire’s geology well and understand how clay soils can affect foundations, especially in older homes where the original structure may fall short of modern standards.

Being close to Buntingford means many residents commute to nearby towns, and properties often go under offer quickly to buyers who have had little time for a proper investigation. Even a house that looks well kept can conceal problems, particularly if it has been freshly decorated for sale. We look behind the cosmetic finish and focus on what is actually going on.

We have surveyed homes across East Hertfordshire for years, so we know the issues that tend to crop up in Cottered. Damp is common in the village’s older properties, especially rising damp in solid-wall construction where a damp-proof course is missing or has failed. Penetrating damp from ageing roof coverings and worn pointing also affects many period cottages, particularly those built with traditional lime mortar that has weathered for decades. Properties overlooking the village green, with their south-facing exposure, often suffer mortar erosion that lets water in.

Timber defects are another familiar problem in Cottered’s older housing stock. Woodworm in floor joists, wet rot and dry rot in window frames, and decay in structural timbers can all spread quickly if they are not picked up early. Some homes have thatched roofs, which need specialist assessment because their maintenance needs and lifespans differ from modern tile or slate coverings. We have surveyed thatched properties where the felt underlay had deteriorated, leaving hidden rot in the rafters that could not be seen from ground level.

Centuries of settlement mean structural movement is common in older buildings. Some movement is perfectly normal in period homes, but our surveyors can tell the difference between ordinary ageing and serious subsidence or structural failure. Hertfordshire’s clay shrink-swell ground movement can be a factor, so we look closely at foundations and any signs of wall movement, especially in buildings erected before modern building regulations. Homes near mature trees are particularly at risk, because tree roots draw moisture from the soil and can accelerate shrinkage.

Outdated electrical and plumbing systems still turn up often in homes that have not been modernised for decades. We pick up unsafe electrical installations, old fuse boards and plumbing systems that may have reached the end of their useful life. If a listing says a property is “requiring modernisation”, our survey explains what that really means in terms of cost and scope. We have seen original 1970s consumer units that would not meet current electrical safety standards, along with lead pipes that create health concerns.

Many Cottered homes have been altered in stages over the years, perhaps with a kitchen extension one decade and a conservatory the next. Our surveyors look at how those additions were built and whether they comply with current building regulations. We often find that older extensions lack proper damp-proof courses or have shallow foundations, which can lead to movement and water penetration where the new work meets the original building.

Knowing how Cottered’s houses were built helps our surveyors spot where problems are most likely to appear. The village’s older properties are mainly traditional brick and timber-framed buildings, and many still have exposed beams and structural timbers that are part of the character of the home. That type of construction is very different from modern cavity wall build, so it needs a different approach. Our surveyors know how to assess mortice and tenon jointing, cruck frames and other historic building methods.

Lime mortar appears throughout Cottered’s older properties, both in brick pointing and in external render. Unlike modern cement mortars, lime allows a building to breathe, which is vital for the long-term health of historic fabric. Our surveys pick up areas where cement mortar has been used on older walls in the wrong way, trapping moisture and causing brickwork to break down. We also identify spots where lime pointing needs repointing to reduce water ingress and frost damage.

The thatched cottages in Cottered need a specialist eye. They are usually roofed in combed wheat reed or long straw thatch, and each has different maintenance intervals and common problem areas. Our surveyors examine the condition of the thatch, check for signs of previous water penetration and inspect the sarking boards below. We also look for evidence of fire damage or earlier repairs that may have affected the integrity of the thatch.

Modern eco-builds in Cottered, such as the five-bedroom detached house completed in May 2024, are built using current methods like insulated concrete formwork, structural insulated panels or timber frame with high levels of insulation. Those systems usually create fewer structural concerns, but our Level 3 Survey still checks insulation installation, ventilation levels and any air-tightness problems that could lead to condensation.
