RICS Level 3 Building Survey in Gilmonby

Gilmonby's housing stock looks nothing like a modern suburban estate. The hamlet is made up mainly of detached farmhouses, traditional cottages and historic rural dwellings built from local Pennine sandstone. Many date from before 1900, and they were put together using methods very different from today's building standards. That is why a RICS Level 3 Survey suits these homes so well. Local sandstone, often pointed with traditional lime mortar rather than modern cement, brings its own set of checks that a generic survey can miss.

Our inspectors know the construction issues that affect properties in this part of County Durham. Carboniferous limestone and sedimentary rocks shape foundation conditions, while the River Greta makes flood risk a real point of attention in the lower-lying parts of the hamlet. We look at every accessible part of the house to build a clear picture of condition. Ground stability and drainage can be affected by the geology, which matters even more where older homes sit on shallower foundations than modern standards would suggest.

Several historic farmsteads sit alongside properties near the Grade II listed Gilmonby Bridge, an early 18th Century structure, so many purchases here involve buildings with plenty of character and a few likely headaches. Traditional lime mortar pointing, solid wall construction and historic roof structures all need specialist eyes. Our surveyors bring that knowledge to every inspection, because character features still need ongoing maintenance or careful repair. Teesdale's wider history of mineral extraction also means mining risk checks matter here.

Because the local economy is so closely tied to agriculture, many homes come with barns, outbuildings or other traditional farm structures that form part of the purchase. Our Level 3 Survey covers those ancillary buildings where they are accessible and included in the property we survey. That way, you know the full reach of any upkeep duties or issues linked to the place you are buying.

• Thorough inspection of all accessible structural elements
• Detailed assessment of historic construction methods
• Flood risk evaluation for riverside properties
• Mining risk consideration for Teesdale area
• Special attention to traditional sandstone and slate building materials
• Assessment of outbuildings and ancillary structures

Gilmonby properties often share a set of issues that our inspectors see again and again in Level 3 Surveys. Knowing those patterns helps you plan for remedial work and price it into the purchase. Age and construction type play a big part, so certain defects turn up more often in this area than in newer places. Our experience across Teesdale means we know where to look and how to judge the common problems.

Damp and moisture penetration are the most common worries in older stone-built homes. Many traditional houses here were built with solid walls and no modern damp-proof course. Traditional lime mortar, while right for the period, can break down over time and let moisture in. Our surveyors check wall condition, look for evidence of past damp treatment and advise on suitable repair approaches for Pennine properties. We can tell whether a damp issue is active or historic, and point you towards specialist advice where it is needed.

Traditional slate roofs account for another frequent source of defects. Slipped slates, worn lead flashing and deterioration in timber rafters and purlins appear regularly in our findings across the area. Many Gilmonby properties are old enough that the original roof covering may be nearing the end of its serviceable life, so we look closely at roof void conditions and set out the repairs needed. We also check previous repairs, assess the roof structure's overall strength and flag any urgent attention.

Older stone structures need a careful look at structural movement, even when the movement is historic. Our inspectors examine wall ties, mortar condition and the stability of load-bearing elements. With many Gilmonby properties, a small amount of movement is not unusual, but we pick out anything that needs further investigation. The key is separating old, stable movement from signs that are still developing and could affect the building's long-term structural integrity. If we spot a concern, we recommend input from a structural engineer.

• Damp and moisture in solid wall construction
• Slate roof deterioration and flashing defects
• Historic structural movement in stone walls
• River Greta flood risk for low-lying properties
• Traditional lime mortar deterioration
• Timber decay in roof voids and floor structures
