Fungi need water in the timber to grow, so every rot repair has two halves: replace the timber that has gone, and remove the water that let it go. Do only the first and you are back in two or three years, usually in the same place. Wet rot is the common one: localised decay in timber that is repeatedly wetted, typically at bargeboard and fascia ends, window sills and joints, door frames at the threshold, rafter feet at leaking eaves, and joist ends bearing into damp walls. Dry rot is less common and more serious: it can spread through masonry to find new timber, so treatment has to be more thorough and the affected area more generously cut back. We inspect the timber and the reason it is wet: gutters, flashings, render, pointing, ground levels, ventilation. Then the specification: how much timber comes out, what goes back, what treatment is applied, and which repair stops the water. One written fixed price, with the moisture source included rather than left for you to arrange separately. ### Who this is for - Properties with soft, crumbling or hollow-sounding external timber - Bargeboards, fascias, sills, door frames and thresholds showing decay at joints and ends - Roofs with rot at rafter feet, wall plates or around chimneys and valleys - Anyone who has found rot during redecoration or a survey before sale - Landlords and commercial premises dealing with decayed joinery or structural timberRing the office on 07460 072891 or use the contact page and we will give you a realistic survey date on the call.

A soft bargeboard end becomes a decayed rafter foot, a wet sill becomes a rotten window frame, and a damp joist end becomes a floor that has to be propped and repaired. Each step multiplies the cost, and the cheapest moment to intervene is always the current one. Dry rot is the case where speed genuinely matters. Its strands can travel through masonry and behind plaster to reach new timber, so an area that looks contained on the surface can be feeding decay in a joist or roof member elsewhere. Cutting corners on the extent of removal is how it comes back. There is also a structural safety point. Wall plates, rafter feet, lintels and joist ends are the timbers holding parts of the building up. Losing section in those is not a decorating issue, and it is not something a filler and a coat of paint has any effect on. ### Common mistakes we are called in to undo - Filling soft timber with resin or filler and painting over it without cutting out the decay - Replacing decayed timber but leaving the leaking gutter, flashing or render that wet it - Cutting back only to where the wood feels firm, leaving affected timber in place - Using untreated timber for external replacements and end grain left unsealed - Sealing the affected area up tight with no ventilation, keeping the moisture in ## How the job runs, step by step - Step 1 ### Inspection We probe and sound the timber to map the extent of decay, identify wet rot or dry rot, and trace the moisture source: gutters, flashings, render, pointing, levels or ventilation. - Step 2 ### Diagnosis and specification Extent of removal, replacement timber, treatment and the repair that stops the water are set out in writing and priced at one fixed figure. - Step 3 ### Remove the moisture source The leak is fixed first: gutter, flashing, render, pointing or ground level, because replacement timber in a wet location has a short life. - Step 4 ### Cut out and replace Decayed timber cut back beyond the affected area to sound wood, new treated timber spliced or replaced in matching sections, and fungicidal treatment applied where specified. - Step 5 ### Protect, verify and complete End grain sealed, timber primed and finished or made ready for decoration, ventilation restored, work checked and walked with you, and waste removed. ## What you get out of it ### Repairs that hold Because the water source is fixed in the same job, the new timber is not decaying quietly behind the new paint. ### Structural timber protected Rafter feet, wall plates and joist ends are repaired before they become propping and rebuilding work. ### Cheaper than the alternative Cutting out early costs a fraction of replacing whole roof edges, frames or floor structures later. ### One team, both halves Roofing, guttering, render, damp and carpentry are all in-house, so the leak and the rot are fixed together. ### Honest extent of works We show you the decay we find and explain why the cut-back goes where it does, rather than trimming the scope to a price. ### Decoration-ready finish New timber is primed and sealed, so painting is straightforward and the protection starts immediately. ## Wood rot repairs in detail: materials, methods and variations ### Wet rot, dry rot and materials Wet rot covers several fungi that decay timber with a persistently high moisture content. It stays local to the wet area, and the repair is proportionate: fix the water, cut out the decay beyond the affected zone, splice in treated timber and protect it. It is by far the most common form we see on external joinery and roof edges in Medway. Dry rot is a specific fungus that can move through masonry and plaster to reach new timber, with strands and fruiting bodies as visible indicators alongside a distinctive musty smell and cuboidal cracking in the wood. It needs a wider cut-back, fungicidal treatment of surrounding masonry where specified, isolation of remaining timber from damp masonry, and thorough drying of the structure. Replacement uses pressure-treated softwood in matching sections for structural work, treated joinery-grade timber for external boards and frames, and resin repair systems only in their proper place: consolidating and rebuilding limited areas of otherwise sound joinery, never as a substitute for cutting out decay. ### Where rot starts, and the fix that lasts The pattern is always water plus timber plus time, so the locations repeat: bargeboard and fascia ends where gutters overflow, sills and joints on weather-facing elevations, thresholds where paving levels are too high, rafter feet under leaking eaves, timbers around chimneys and valleys, and joist ends bearing into a damp external wall. That last one is why damp proofing and rot repair belong together. A joist end sitting in damp masonry will decay again unless the wall is treated and the timber isolated from it, which is a damp specification, not a carpentry one. Ventilation is the quiet part of the fix. Sub-floor voids, roof spaces and boxed-in areas need air movement to keep timber dry; the repair that seals everything up neatly and blocks the last vent creates the conditions for the next round of decay. ### Residential versus commercial On houses the visible work is joinery: matched sections, clean splices, primed and sealed ready for decoration, with the roofing or damp fix behind it. We work room by room or elevation by elevation with protection and daily clear-down. On commercial premises the concerns are structural timber, safe access and continuity: propping and sequencing where roof or floor members are affected, works phased around trading, and clear reporting of what was cut out and why for building owners and managing agents. ## Wood rot repairs: your questions answered How much do rot repairs cost?It depends entirely on how much timber is affected and whether structural members are involved. A bargeboard end and a decayed wall plate sit far apart in cost. We inspect, map the extent and give a fixed written price including the repair that stops the water. How long does the work take?Localised joinery repairs are often a day or two. Structural work at rafter feet, wall plates or joist ends, or work involving roofing and damp repairs, typically runs several days to a week or more. Is it wet rot or dry rot?Wet rot stays local to the damp area; dry rot shows strands, fruiting bodies, a musty smell and cuboidal cracking, and can spread through masonry. We identify which at the inspection and explain what we are looking at. Can rotten timber just be filled?No. Filler and resin have a place consolidating limited areas of otherwise sound joinery, but they add nothing structurally and they do not stop decay. Affected timber has to be cut out. Will the rot come back?Not if the water is gone. Every repair we quote includes fixing the moisture source: gutter, flashing, render, pointing, ground level or ventilation, because timber replacement alone is a temporary measure. Do you fix the leak as well?Yes, and it is done first. Roofing, rainwater goods, render and damp proofing are all in-house, so you are not coordinating two contractors around one repair. Do you treat the surrounding timber and masonry?Where the diagnosis calls for it, particularly with dry rot, fungicidal treatment and isolation of timber from damp masonry are specified as part of the works, and set out in the quote. Do you cover my area?Medway, Rochester, Chatham, Gillingham, Strood, Rainham, Maidstone, Sittingbourne, Sheerness and the surrounding Kent towns. ## Get wood rot repairs priced properly: free survey, fixed written price Tell us what you are seeing and we will book a survey, diagnose the cause and give you one written price. 9.97 out of 10 from 12 Checkatrade reviews across Medway and Kent.
