Hidden damp is the main cause of timber decay, and a damp and timber survey is the quickest way to find it and protect your floors, joists, roof timbers and window frames. At Dampshop Services, we offer timber decay Swindon inspections and wet rot and dry rot treatment for homes and businesses across Swindon and nearby towns.
Why Timber Decay Often Goes Unnoticed
Timber decay usually starts in places you rarely look: under floorboards, behind radiators, inside lofts, beneath bath panels and within sub floor voids. Moisture arrives slowly through a leaking pipe, a blocked gutter, rising damp or steady condensation. Fungal spores are present in most buildings, and they begin to grow once timber stays damp for long enough. Acting at the first sign keeps repairs small and straightforward.
What Causes Damp to Reach Timber
- Rising damp moving up walls and into skirting boards and floor joists
- A hidden pipe or waste leak near floors and walls
- Blocked gutters, loose roof tiles and worn seals around windows
- Poor airflow in lofts, cellars and under floor spaces
- Ongoing condensation in bathrooms, kitchens and bedrooms
- Raised ground levels or render that bridges the damp proof course
Wet Rot, Dry Rot and Woodworm: Spot the Difference
| Feature | Wet Rot | Dry Rot | Woodworm |
|---|---|---|---|
| Moisture level needed | Higher | Lower | Damp or older timber |
| Spread | Stays near the damp source | Can travel through walls and plaster | Tunnels within timber |
| Typical look | Dark, soft, spongy wood | Deep cracks in cube shapes, grey strands, red spore dust | Small round exit holes and fine dust |
| Smell | Musty | Strong mushroom scent | Often none |
| Best next step | Fix the damp source, then treat and repair | Prompt survey and treatment | Survey and timber treatment |
Understanding which one is present shows how quickly to act. Wet rot settles down once the moisture source is fixed and the area dries. Dry rot can reach timber some distance from where it started, so it needs a specialist survey. Our wet rot and dry rot service covers identification, treatment and timber repair, and our guide to wet rot vs dry rot explains the signs in more detail.
Early Signs of Timber Decay to Look For
- Timber that feels soft, spongy or darker than the wood around it
- Cracks, crumbling edges or a hollow sound when tapped
- Paint that flakes or lifts with dark staining beneath
- A musty or mushroom like smell in a room, loft or cupboard
- Skirting boards and floorboards that move or bounce
- Fine dust or small round holes in the wood
- White strands or a pancake shaped growth on timber or masonry
If you notice any of these signs, a timber decay Swindon survey will confirm the cause and the right solution.
A Two Minute Home Check
- Look under sinks and around bath panels for damp timber
- Check window frames and sills for soft spots using a small screwdriver gently
- Lift a loft hatch and look for dark patches on rafters and the roof underside
- Check the base of staircases and door frames on ground floors
- Walk around outside and look at gutters, downpipes and ground levels near walls
How We Find Hidden Damp and Timber Decay
Our surveyors use a moisture meter, a hygrometer, a thermal imaging camera and a careful visual inspection to trace the moisture source and the extent of any decay. This helps us tell rising damp, condensation and hidden leaks apart before any work begins. Our article on thermal imaging for damp and leaks shows how this works in practice. Buying a property? A pre purchase damp and timber survey gives you clear answers before you commit.
How We Protect Your Timber
- Fix the moisture source. This could be a leak repair, a new damp proof course through our rising damp service or damp proofing service, or better airflow through our condensation control service.
- Dry the structure. Our property drying service brings moisture levels back to a healthy range.
- Treat the timber. Specialist fungicides protect sound wood and guard against future growth.
- Repair and replace. We cut back affected timber to a safe margin and replace it with treated wood where needed.
- Protect for the future. We advise on ventilation, gutters, ground levels and regular checks.
Keep Timber Healthy All Year
- Clear gutters and downpipes each autumn
- Keep sub floor air bricks open and free of soil
- Use extractor fans in kitchens and bathrooms
- Repaint and reseal external window frames and doors
- Fix leaks quickly and dry any wet areas
- Book a damp and timber survey every few years for older properties

Frequently Asked Questions
What causes timber decay in Swindon homes?
Timber decay comes from moisture that stays in wood for a long time. Typical sources are rising damp, leaks, blocked gutters, poor ventilation and ongoing condensation.
How do I know if I have wet rot or dry rot?
Wet rot makes timber dark, soft and spongy near the damp source. Dry rot shows deep cube shaped cracks, grey strands and red spore dust, and can spread through walls. A survey confirms which one is present.
Can timber decay be treated without replacing all the wood?
Often yes. Wet rot treatment usually involves fixing the moisture source, drying the area and treating and repairing the timber. Dry rot treatment includes cutting back affected wood and masonry treatment, so a specialist survey is the best first step.
How long does a damp and timber survey take?
Most surveys are completed in one visit, and we explain the findings and the recommended solution in clear language.
Is hidden damp always visible?
Not always. Moisture can sit behind plaster, under floors and inside roof spaces. Moisture meters and thermal imaging help us find it without unnecessary opening up.
Should I get a timber survey before buying an older property?
Yes. A damp and timber survey highlights moisture and early decay that are hard to see by eye, giving you confidence in your purchase.
