RICS Level 3 Building Survey in Irnham

Irnham’s status as a Conservation Village means many homes here were built using traditional methods refined over centuries. Exposed limestone walls are something our surveyors often see, especially in Irnham Park and across the village. Lincolnshire Limestone has been part of local building for generations, and while it gives the area its distinctive look, it also needs specialist knowledge if it is to be assessed properly. Our inspectors look closely at pointing, damp moving through the stonework, and any signs of structural movement that could affect these older buildings.

Another factor is the ground beneath the village. The Kesteven Plateau where Irnham sits has Jurassic limestone bedrock, with large areas covered by glacial boulder clay drift. That mix can lead to uneven ground conditions, so foundations may behave differently from those on more uniform soil. Near the East Glen River, we pay particular attention to drainage and any moisture-related issues, even though river levels typically remain normal according to Environment Agency monitoring.

Older homes make up much of Irnham, and many pre-date modern building regulations. With a concentration of listed buildings, from the Grade I Irnham Hall to numerous period farmhouses and cottages, alterations and extensions may have been added over many decades to different standards. Our Level 3 Survey looks at the property as a whole, picking out previous work that may not meet current requirements and could need attention.

With approximately 168 residents across roughly 70 households, the village feels small and closely connected. Properties here often come with traditional outbuildings, boundary walls and rural features that need a careful look. Our inspectors know this type of setting well, and they understand how to spot defects that can slip past a standard valuation.

Far more detail is provided by the RICS Level 3 Survey than by a standard mortgage valuation. We assess all the major parts of the property, from foundation to roof. Walls are checked carefully for cracks, movement or deterioration that could point to structural problems. Our inspector also looks at the roof covering, flashing and chimneys, along with flat roofs where they are present.

Inside, we inspect floors, walls and ceilings, noting significant defects such as damp staining, cracking or evidence of previous movement. Windows and doors are checked for condition and operation, and fitted kitchens or bathrooms are assessed too. The report also reviews the property’s services, including electrical, gas, heating and drainage systems, although these remain visual inspections rather than specialist testing.

For Irnham properties, we give particular weight to local construction details. Exposed limestone walls are assessed for frost damage, salt efflorescence and mortar deterioration. Any boundary walls or outbuildings are examined as well, since these are common in rural properties here. The report gives an honest account of condition, setting out issues that need immediate attention and others that may need planning for later.

We also look at annexes, garages and any converted spaces on the property. Because many Irnham homes include old farm buildings converted to residential use, our surveyors are familiar with the issues that can follow, including insulation standards, ventilation and structural alterations.

The report is laid out clearly and is easy to follow, with findings split into condition ratings. Every part of the property is graded from "Good" to "Very Bad", with defects described and photographed. An Executive Summary brings together the most important points, so you can quickly get a sense of the property’s overall condition.

We know that not every buyer is a construction expert, so the report avoids needless technical language. Where technical terms do appear, we explain them in plain English. There is also a section devoted to the construction of the specific property type, helping you understand how the building works and why certain defects may have occurred.

For Irnham properties with features such as traditional lime mortar pointing, original stonework or historic extensions, we provide focused guidance on maintenance. New owners then know how to care for their historic property properly, rather than making the mistakes that can damage traditional construction. Our inspectors understand why the right materials and methods matter so much with historic buildings.

We also include a section on legal matters that may affect the property, including rights of way, easements and planning issues you should be aware of. For homes in or near the conservation area, we note any relevant designations that could influence future alterations or improvements.
