Wet & Dry Rot Treatment In Nottingham
If timber in your home feels soft, spongy or crumbles under light pressure, you could be dealing with wet rot or, in more serious cases, dry rot spreading through the structure itself.
Midland Preservation Ltd has carried out wet and dry rot treatment in Nottingham and across the East Midlands for over three decades, and every case begins with a detailed inspection from a CSRT qualified surveyor, not just a quick chemical spray.
As Property Care Association members, we correctly identify which type of fungal decay you're dealing with before recommending treatment, because the two require very different approaches, and getting that diagnosis wrong can be an expensive mistake.
Wet Rot Explained
Wet rot is a general term for several types of fungal decay that attack timber once its moisture content rises above 20 percent, most commonly Cellar Fungus (Coniophora puteana) and Mine Fungus (Poria vaillantii).
Unlike dry rot, wet rot generally stays confined to the timber that's actually wet, and once the source of moisture is removed, it stops spreading.
It's still serious though: left long enough, wet rot will destroy the structural strength of a joist, beam or skirting board just as effectively as dry rot, simply more slowly and less dramatically.
Dry Rot Explained
Dry rot, caused by the fungus Serpula lacrymans, is the most serious form of timber decay found in UK buildings, and there is only one type.
Dry rot (Serpula lacrymans) is a unique type of timber decay, where despite the name, affect wet timbers (above 20% moisture content) and is normally associated with excessive moisture from penetrating damp from defective rainwater goods, plumbing leaks, lack of subfloor ventilation under timber floors.
What makes it so destructive is that its root like strands, known as mycelium, aren't limited to the timber itself: they can spread across and through plaster and masonry to affect other adjacent timbers.
Controlling and eradicating Dry rot (like any timber decay) is less about treatment and more about understanding and eliminating the causes of the moisture/water, before any treatment works are carried out.
Wet / Dry Rot – Signs To Look For
- Soft or spongy timber: wood that gives way under gentle pressure, often found in skirting boards, joists or window frames.
- Crumbling, cuboidal cracking: timber that has broken into small brick like cubes is a classic sign of dry rot.
- Musty, damp smell: dry rot in particular produces a distinctive, sweet, musty odour.
- Discoloured or shrinking wood: timber that looks darker than surrounding wood or has visibly shrunk.
- White or grey fungal growth: cotton wool like strands or a pancake shaped fruiting body are strong indicators of active dry rot.
What Causes Wet / Dry Rot?
Both forms of fungal decay need the same trigger: timber with a moisture content above 20 percent, sustained for long enough to allow fungal spores to establish.
This usually traces back to a source of ongoing dampness, a leaking pipe, a defective roof, rising or penetrating damp, or poor ventilation beneath a suspended timber floor.
Wet rot tends to develop wherever that moisture is present, while dry rot is more likely to take hold in enclosed, poorly ventilated spaces such as beneath floors or behind panelling, where conditions stay damp and still for long periods.
How We Diagnose & Treat Wet / Dry Rot
Correctly identifying which type of rot you have is the single most important step, since wet rot treatment is far less invasive than dealing with an active dry rot outbreak.
Our CSRT qualified surveyors carry out a detailed inspection, checking timber condition, moisture readings and, where necessary, the surrounding brickwork and plaster, before issuing a written report and schedule of works.
For wet rot, treatment usually means removing the source of moisture and cutting out and replacing the affected timber, isolating any new timber from future dampness with a physical damp proof membrane.
For dry rot, the affected timber is removed along with a margin of surrounding material, and any brickwork the mycelium has reached is treated with a fungicidal sterilisation to make sure nothing is left behind to regrow.
Our Five Stage Wet / Dry Rot Treatment Process
Enquiry
Call us or send a message describing what you've found and we'll arrange a survey at a time that suits you.
Assessment
One of our CSRT qualified surveyors inspects the affected timber and surrounding structure in your Nottingham property.
Diagnosis
You receive a written report confirming whether you're dealing with wet rot or dry rot, how far it has spread, and a fixed price quotation for the work required.
Treatment
Our tradespeople remove and replace affected timber, and where dry rot has spread into brickwork or plaster, carry out fungicidal sterilisation to stop it returning.
Guarantee
Every job comes with a 10 year guarantee, so you have long term confidence the decay has been fully eradicated.
Book Your Wet & Dry Rot Survey In Nottingham
Fungal decay rarely stays contained once it's established (particularly dry rot) so the sooner it's correctly diagnosed, the less timber and brickwork you're likely to lose.
If you've spotted soft timber, fungal growth or a musty smell, or you'd simply like an honest opinion from a Property Care Association member with 30 years of experience, call us on 0115 946 4484 or request your survey today.
Fungal decay is very often linked to an underlying damp problem, so it's worth having both checked together, take a look at our damp proofing services for more information.
