Brompton is a compact garrison village of old terraces next to the Dockyard. Old homes need careful damp advice.
Brompton's terraces are largely 17th to 19th century solid brick, some rendered, many in a conservation area. Damp there is usually condensation made worse by sealed-up flues and cement repairs that trap moisture, or penetrating damp from failing roofs and gutters. Treat the cause gently. A loft-mounted dehumidifier can help with condensation in owner-occupied homes with a loft, but alterations to listed or conservation-area buildings need consent checks first.
Medway Council's conservation area appraisal describes Old Brompton as modestly sized, densely packed two to three storey terraces fronting directly onto the road, in a formal grid of streets, many only two bays wide. Most buildings date from the 17th to the 19th century.
Early houses are in a deep brown brick, with brighter orange-red brick by the mid to late 18th century and light yellow stock brick in the early 19th. Roofs are mostly clay tile, with some slate. In Mill Road and Saunders Street the appraisal notes that yellow brick has often been covered in render.
The same appraisal records alterations such as render over facades, and concrete tiles replacing clay tiles. Neither is automatically wrong, but cement render on a solid wall can stop it drying out, and heavier tiles or blocked ventilation under old roofs change how moisture moves.
If you are chasing damp on a Brompton terrace, ask what has been done to the wall in the last fifty years before you ask what product to add.
Narrow two-bay houses have small rooms and little space for moisture to disperse. Bedrooms on the cold side, the wall behind a wardrobe, and the chimney breast are the usual places. A solid brick party wall is warm, but an external gable or rear wall is not.
Much of Brompton is within the Brompton Lines Conservation Area, and some buildings are listed. Changes to the outside of a building, and some internal work on listed buildings, can need consent. Check with Medway Council before changing windows, render or roofs, and ask us at survey whether any loft work would be affected.
Dryzen needs a loft to mount the unit, insulated ducting runs only to the central area or stairway, and the smart app needs 2.4GHz Wi-Fi. It is for owner-occupied homes, not rentals unless the landlord authorises the changes. On listed or conservation-area buildings, check consent first.
Some moisture is normal, because solid walls hold and release it, but visible mould or a persistent musty smell is not. It usually means moisture is being added faster than it escapes.
Alterations that affect listed buildings can need consent, and conservation areas restrict some exterior changes. A loft-mounted unit with ducting is mostly internal, but check with Medway Council before you start. For the full evidence, calculator and printable cheat sheet, see The Healthy Home Humidity Guide.
Cement render can trap moisture in a solid wall, especially where it is cracked. Lime-based render lets walls dry. Which is present on your house is worth checking before any repair.
Yes. Dryzen is mounted in the loft, so a house without a loft is not suitable.
It helps stop the conditions mould and dust mites favour, with 50 to 55 percent a sensible target. It is not a pesticide and does not kill mould, spiders, fleas or bed bugs, and it will not fix a leaking roof or gutter.
