*Disclaimer: Rescheduled visits are billed at the original quoted rate.
Scaffold-Free Heritage Audits.
Why pay for access when you can pay for data?
Hiring scaffolding near historic properties in Chepstow can be costly and logistically challenging.
Our drone survey provides a faster, safer alternative:
- ✅ Evidence for Insurance: Validation for storm damage claims with 4K photos.
- ✅ Protection from Upselling: Use our independent report to verify what repairs are actually needed.
- ✅ Trace and Access: Find the exact entry point of a leak in minutes.
Chepstow: Heritage Fabric in an Estuary Climate
Listed stone in the old town, fully exposed pitches above the Wye and the Severn.
Listed and Conservation-Area Roofs
The streets below the castle carry listed buildings and conservation-area controls, which makes physical access a paperwork problem as well as a cost. A drone touches nothing and needs no consent, so a Chepstow heritage roof can be inspected in full — stone slate, lead valleys, complex junctions — with no application and not a single fixing into historic fabric.
Wye and Severn Salt Exposure
Properties looking down the estuary take salt-laden wind that attacks lead, zinc and mortar faster than inland stock of the same age. Oxidised flashings and open mortar joints are the usual finding. We fly the exposed elevation and record it, giving you a baseline to compare against after the next storm.
Narrow Streets and Rural Estates
The old town's streets make a scaffold licence anything but straightforward, while Shirenewton and the outlying estates have roofs too spread out to walk economically. Both problems suit an aerial survey: one launch point, twenty minutes, and the entire roof area on file.
Evidence, Not an Estimate
CalonTerra carries out no roofing or masonry work, so nothing in a Chepstow report leads back to a job for us. You receive the imagery, the 4K video and a written condition assessment at a fixed price — which is precisely the form a conservation officer, a lender or an insurer wants it in.
Buying or Selling in Chepstow?
"The survey flagged a potential roof issue."
Banks often demand a "Specialist Roof Report" before releasing funds. Standard surveys often can't see high roofs properly.
The Solution: We provide the high-level evidence your lender requires to lift the retention.
Insurance Claims & Storm Damage
If you are claiming for "Storm Event" damage, your insurer will demand proof that the damage is recent.
- ✅ HD Evidence: 4K photos of fresh damage.
- ✅ Date-Stamped Data: Proof for your claim.
- ✅ Independent Validation: Unbiased reports.
Typical Defects We Expose
Damaged / Slipped Tiles
Identify slipped or missing slates causing water ingress. Critical for Trace and Access.
Chimney Stack Pointing
Check for lead flashing issues and cracked pointing on tall stacks.
Blocked Guttering Check
Spot vegetation growth and sagging brackets from above.
Fascia / Soffit Issues
Identify water damage and rot on wooden fascia boards.

Chepstow Drone Surveys: NP16 Questions
What Chepstow, Bulwark, Sedbury and Shirenewton customers ask.
Do I need listed building consent for a drone survey?
No. Consent governs alteration to the building, and an aerial survey alters nothing — no fixings, no scaffold ties, no contact of any kind. That is why non-invasive inspection is often the sensible first step before any consent application is even drafted.
Can you fly near Chepstow Castle and the racecourse?
In most cases yes, subject to checks on the day. We confirm airspace, overflight of uninvolved people and any event schedule before quoting, and we operate under our A2 Certificate of Competency, the qualification specifically concerned with flying close to people and property.
Do you cross the border into Sedbury and Tutshill?
Yes. The Gloucestershire side of the bridge forms part of our normal Chepstow coverage and is quoted the same way, with travel calculated from our Pontypool base and displayed in the form on this page.
What do you find most often on Chepstow properties?
Failed or lifted lead in valleys and around stacks, open mortar joints on exposed stone, and slipped stone or slate on the estuary-facing pitch. On rural properties it is more often blocked valley gutters and vegetation established on outbuildings.
Can you survey a farm or estate with several buildings?
Yes, and it is one of the strongest uses of the aircraft. A group of buildings around Shirenewton or St Arvans that would take a full day to inspect with ladders can be flown in a single sortie, with every roof documented separately in the report.
