Survey appointments in Rochester are easy for us to slot in, and if water is actively coming in we can usually get someone to the property fast enough to make it safe the same day. The building stock here is unusually varied for one town. There is genuine period property along the High Street, Star Hill, Victoria Street and the streets behind the cathedral: solid brick, sash windows, cellars, lath and plaster. Then the Victorian and Edwardian terraces climbing Delce and City Way, inter-war semis around Borstal and Wouldham Road, post-war estate housing at Wainscott and Frindsbury, and modern development on the Medway City and riverside fringes. That mix decides the work. In the old town we are almost always dealing with solid-wall damp, failed or absent damp proof courses, cellars that need tanking, and lime-appropriate finishes rather than dense cement. On the hill terraces it is penetrating damp around chimney stacks and bay returns plus roofs at the end of their covering life. In Wainscott and Frindsbury it is concrete interlocking tiles, rusted nails, tired flat garage roofs and rotten timber fascias replaced in UPVC. Rochester also sits on the tidal Medway, and the streets that drop towards the river take the full weather off the water. Sloping ground behind the High Street and up the Delce means many properties have retaining walls, cellars and lower-ground rooms with earth against them, the single most common reason we are asked to tank in Rochester. Our Checkatrade reviews include ME2 addresses for re-roofing, soffit and downpipe replacement and general renovation, so the local work is verifiable rather than claimed.

Cementitious tanking or a cavity drain membrane makes those rooms dry and usable again. - Damp proofing period terraces: Injected damp proof courses, salt-resistant replastering and ventilation for solid-wall houses on the Delce, City Way and around the cathedral. - Chimney and flashing repairs: Repointing, re-flaunching and new lead trays on the tall stacks that come with Rochester's older housing, a frequent source of internal damp. - Re-roofing 1930s to 1970s stock: New battens, breathable membrane, dry-fixed ridge and reformed valleys on roofs in Wainscott, Frindsbury and Borstal that are past repair. - Rendering and exterior painting: Cracked cement render stripped and replaced in silicone or monocouche, then breathable coatings on masonry that faces the river weather. - Fascias, soffits and guttering: Rotten bargeboards and leaking gutters replaced in UPVC so rainwater stops running down the face of the wall. ### Nearby areas we cover - Strood - Chatham - Medway - GillinghamAll areas ## Services available in Rochester ### Damp Proofing in Rochester Rising and penetrating damp diagnosed at source, then treated with injected damp proof courses, replastering and ventilation that keeps walls dry for good.

Short journeys mean earlier survey dates and quicker attendance when a roof is letting water in. ### ME2 customers in our reviews Checkatrade reviews from ME2 addresses cover part re-roofing, soffit and downpipe replacement in UPVC, and a wider renovation, all Rochester-area work. ### Period property experience We specify breathable systems on solid walls instead of sealing moisture in, and we say plainly when a property's construction rules an approach out. ### One team for cause and consequence Roof, render, gutters, tanking, plastering and decorating handled together, so a damp problem is closed out rather than passed between trades. ### Fixed written pricing Free survey first, then one written price. Reviewers note we held the original quote even where extra work was carried out. ## Problems we deal with most in Rochester ### Earth-retaining walls and wet cellars Rochester's older streets climb steeply from the river, so a great many properties have at least one wall holding back soil: a cellar under the front rooms, a lower-ground kitchen, a store cut into the slope. Those walls stay wet because the ground against them stays wet, and after prolonged rain water runs downhill through neighbouring gardens and arrives under pressure. We assess whether the substrate will take a bonded cementitious tanking system or whether the sensible answer is a cavity drain membrane with a perimeter channel, sump and pump that manages water instead of trying to hold it back. On period property the choice also has to respect the wall's need to breathe elsewhere, which is why we survey before recommending rather than fitting one system to every job. ### Solid walls treated with the wrong materials A recurring Rochester problem is well-meant previous work. Solid brick walls that need to breathe have been coated in dense cement render, sealed with masonry waterproofer, or replastered internally in gypsum straight onto damp brick. Moisture that used to evaporate now has nowhere to go, so it travels sideways and upwards and appears somewhere new. Putting that right starts with removing what is trapping the water. We strip failed cement and impermeable coatings, allow the wall to dry, and rebuild the finish in materials appropriate to the construction: breathable render outside, salt-resistant or lime-based systems inside. It is more work than another coat of paint, and it is the difference between a repair that lasts and one that reappears next winter. ### Tall Victorian chimney stacks The terraces on the Delce, City Way and around the old town came with tall, often shared chimney stacks. A century on, the flaunching has cracked, the pointing has eroded, lead trays and flashings have lifted, and unused flues are open to the sky. Rain gets into the brickwork and reappears internally on the chimney breast, sometimes on a bedroom wall two floors down from the leak. We repoint and re-flaunch, renew lead trays, aprons and step flashings, cap or vent redundant flues, and remove stacks entirely and make good the roof where they are no longer needed. Because we survey the whole roof at the same time, you find out whether the stack is the only problem before you spend money on it. ### River-facing weather and eroded pointing Elevations that look towards the Medway take wind-driven rain repeatedly on the same face. Over decades that scours out soft mortar joints, opens hairline cracks in render into water paths, and saturates brickwork faster than it can dry between showers. The internal symptom is a patch that appears within hours of heavy rain and fades slowly afterwards. Fixing it means working outside: raking out and repointing in a mortar that suits the brick, re-rendering where the existing coat is hollow, sealing around window and door reveals, and correcting rainwater goods so water is carried away rather than dumped against the wall. Internal replastering comes afterwards, once the wall is dry. ## How a Rochester job runs, step by step - Step 1 ### Call or message Tell us the street or postcode and what you are seeing. We book a survey slot on that call and confirm it in writing, so you are not waiting on a callback that never comes. - Step 2 ### Survey and diagnosis We come out, get on the roof or into the affected rooms, take moisture readings or photographs as needed, and find the cause rather than guessing at the symptom. - Step 3 ### Fixed written price You get one written estimate covering materials, labour, access and making good.

Call 07460 072891 for a date on the call. How much does damp proofing cost in Rochester?The honest answer is that it depends on wall thickness, room sizes, external ground levels and how much replastering is needed, which is why the survey is free and the price comes afterwards in writing. You get one fixed figure covering everything, not an hourly rate that grows. Can you tank a cellar in an old Rochester property?Yes, and it is one of our most common Rochester jobs. We survey the structure first and then recommend either a bonded cementitious tanking system or a cavity drain membrane with channel and sump, depending on the walls, the water and how you want to use the room. Do you offer emergency roof repairs in Rochester?Yes. Storm damage, slipped tiles, a stripped ridge or a leaking flat roof are prioritised, and being local we can usually get there quickly to make things watertight before agreeing the permanent repair. Do you work on listed buildings and conservation areas in Rochester?We work on period property regularly and specify materials suited to historic construction. Listed building consent and conservation area approval are Medway Council's process, not ours, but we will tell you before quoting what is likely to be acceptable and what is not. How long does a re-roof take in Rochester?A typical terraced or semi-detached re-roof runs from a few days to around a fortnight, depending on size, access, scaffold requirements and whether battens, timbers or chimney work are involved. Your written estimate sets out the expected duration before you commit. Which other areas near Rochester do you cover?Strood, Chatham, Gillingham, Rainham and the wider Medway towns, plus Maidstone, Sittingbourne and Sheerness.
