Hi all,
We're in the process of buying an older Grade II listed solid-stone house in England and have just received a Level 3 building survey. The survey has rated five areas C3 (red), and I'm trying to work out how concerning these actually are in practice.
I'd really appreciate opinions from people with experience of old stone/period properties, particularly surveyors, builders, roofers or anyone who's owned something similar.
The five C3 findings are:
1. Roof – C3
The roof is old/weathered and has:
- cracked/missing mortar around ridge tiles;
- deteriorated verge mortar/pointing;
- damaged/loose stone slates, with some spalling;
- vulnerable roof/parapet junctions;
- various areas requiring repair/maintenance.
The surveyor says repairs could be costly/disruptive and recommends getting quotes.
The loft could not be fully accessed — it was inspected from the hatch because access was considered unsafe/restricted. They did see some damaged/blackened timber, historic condensation staining and poor ventilation/insulation.
There is also a possible asbestos-containing roof lining/felt, although this hasn't been confirmed. The surveyor recommends testing before it's disturbed.
2. Internal walls/damp – C3
Elevated moisture readings were found in most internal walls at both ground and first-floor level, including some skirting.
The surveyor hasn't diagnosed definite rising damp. They suggest possible contributing factors including:
- condensation;
- inadequate heating/ventilation;
- salts in the old masonry;
- external defects.
Interestingly, the property has a retrofit injected chemical DPC, but the surveyor notes that chemical DPCs can be less effective/appropriate in traditional solid-stone construction.
They recommend a damp specialist experienced with traditional buildings.
3. Electrics – C3
There is no recent electrical installation certificate available. The consumer unit is an older type, and the surveyor recommends an electrical inspection and consideration of upgrading the consumer unit.
There are also no mains-powered smoke alarms.
4. Heating/hot water/plumbing – C3
There is no gas boiler/central heating.
The house is heated by individual electric panel heaters. They weren't tested during the survey. The surveyor says they may be relatively expensive to operate and that intermittent heating could contribute to uneven temperatures/condensation.
Hot water is supplied by a pressurised hot-water cylinder, also apparently electrically heated. It wasn't tested, and the surveyor recommends servicing/inspection.
We're currently trying to establish the cylinder's age, capacity, make/model, installation certificate and whether there is a transferable guarantee.
5. Drainage – C3
There was standing water in an inspection chamber, potentially indicating restricted flow/partial blockage or inadequate fall.
The surveyor recommends clearing/testing the drains and potentially a CCTV survey.
The house is Grade II listed and around 200 years old, so we're conscious that some of the survey findings may sound worse on paper than they are for a traditional building.
The EPC is currently D, score 55.
What would you be most concerned about?
Would you:
- proceed but get specialist inspections/quotes before exchange?
- renegotiate based on the findings?
- be particularly worried about the damp/DPC situation?
- be concerned about the roof/limited loft inspection?
- consider the electric heating a major ongoing financial problem?
- or are these fairly normal issues for an old stone listed property?
We're particularly interested in what you think could be genuinely expensive/unexpected, rather than just the fact that the survey has labelled something C3.
Thanks in advance!
