It's Been a Busy Week—With a Few "Eeeek!" Moments
This week has been packed with property surveys across Peterborough and Cambridgeshire, and as always, we've uncovered issues that buyers would have completely missed during their initial viewings.
These hidden defects could have cost homebuyers thousands in unexpected repairs—or worse, made their properties unsafe or unmortgageable.
Here's a behind-the-scenes look at what we found this week, why professional surveys matter, and one very unexpected "guest" who kept watch during an inspection! 👀
1. Roof Defects: Missing Tiles & Water Ingress
Our drone survey revealed multiple missing roof tiles and damaged flashing on a property in Peterborough. From ground level, this damage was invisible—but from above, the extent of the problem was clear.
What We Found:
- Missing and slipped roof tiles allowing water penetration
- Damaged flashing around chimney stack
- Potential for water damage to loft timbers and insulation
Cost to Fix: £800–£2,500 (depending on extent of water damage)
Why It Matters: Left untreated, roof leaks cause damp, rot, and structural damage. This buyer now has the evidence needed to negotiate a price reduction or request repairs before completion.
2. Chimney Stack Cracks: Structural Red Flag
Chimney stacks are often overlooked during property viewings—but they're critical structural elements. This week, our drone inspection identified significant cracking in a chimney stack that was completely invisible from ground level.
What We Found:
- Diagonal crack running through chimney brickwork
- Potential for water ingress and further deterioration
- Risk of chimney instability in high winds
Cost to Fix: £1,500–£4,000 (chimney rebuild or repointing + flashing replacement)
Why It Matters: Cracked chimneys can collapse, causing serious damage and safety hazards. Early detection prevents expensive emergency repairs.
3. Collyweston Slate Roof: Holes, No Felt, Water Damage
This property had a beautiful historic Collyweston slate roof—but beneath the surface, serious problems were brewing.
What We Found:
- Multiple holes in Collyweston slate tiles
- No roof felt/underlay (common in older properties but a major issue)
- Active water ingress into loft space
- Timber rot and woodworm infestation caused by moisture
Cost to Fix: £5,000–£12,000+ (Collyweston slate replacement + timber treatment + felt installation)
Why It Matters: Collyweston slate is a premium roofing material, but repairs are expensive. Without urgent action, the entire roof structure is at risk of failure.
4. High Moisture Content & Woodworm: The Hidden Damage
Using our calibrated moisture meters, we detected dangerously high moisture levels in roof timbers—a direct result of the holes in the roof and inadequate ventilation.
What We Found:
- Moisture readings of 25%+ (anything over 20% indicates active rot risk)
- Active woodworm infestation (small holes and frass visible)
- Soft, weakened timber in multiple roof joists
- Inadequate roof ventilation exacerbating the problem
Cost to Fix: £2,000–£5,000 (timber treatment + ventilation improvements + affected timber replacement)
Why It Matters: Woodworm and rot spread rapidly. Left untreated, structural timbers fail, causing roof collapse. This buyer avoided a potential disaster.
5. The Unexpected Survey Guest: Rick Grimes! 🧟
Every surveyor has their share of surprises—but this week's was particularly memorable!
While inspecting a garage, I turned around to find myself face-to-face with a life-size cardboard cutout of Rick Grimes from The Walking Dead. Safe to say, it gave me a bit of a jump! 😅
Lesson learned: Always expect the unexpected during property surveys. Whether it's structural defects or zombie apocalypse survivors, we're prepared for anything!
---6. Blocked Drains: Look Away If You're Squeamish! 🚨
Part of every RICS survey involves checking manholes and drainage systems. This week, we lifted a manhole cover and found severely blocked drains that required immediate attention.
What We Found:
- Multiple blocked drains with standing water and debris
- Foul odors indicating sewage backup
- Potential for drain collapse if left untreated
- Risk of water damage to foundations and property structure
Cost to Fix: £500–£2,000 (professional drain cleaning + CCTV survey to assess pipe condition)
Why It Matters: Blocked drains cause damp, structural damage, and health hazards. They're also expensive to fix if pipes have collapsed. This buyer now knows to budget for immediate drainage work.
Why These Issues Would Have Been Missed
Here's the reality: none of these defects would have been spotted during a standard property viewing.
- ❌ Roof defects: Invisible from ground level without drone inspection
- ❌ Chimney cracks: Too high to see without specialist equipment
- ❌ Moisture & woodworm: Hidden in loft spaces, only detectable with moisture meters
- ❌ Blocked drains: Underground and out of sight unless manholes are lifted
Total potential repair costs across these properties: £10,000–£25,000+
Our surveys gave these buyers the evidence they needed to:
- ✅ Negotiate price reductions
- ✅ Request seller repairs before completion
- ✅ Budget accurately for post-purchase works
- ✅ Make informed decisions about whether to proceed
