Damp Proofing Stevenage Hertfordshire (SG1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


The following article describes what may cause such damp problems in Stevenage, and the various methods of preventing and solving them.


Problems like loose or cracked roof tiles, cavity wall issues, unsound brickwork and damaged guttering are common external causes of penetrating damp. Inside a structure, burst or leaky pipes, cracked shower trays and overflowing basins or bathtubs, can cause penetrating damp. If left to continue leaking these elements enable water to seep into the walls and woodwork, which in time result in blistered or broken plaster, dark damp patches on walls and peeling paintwork.

If you've got a leaky roof and it has been neglected for an extended period of time, it can cause wet rot to develop in your roof timbers. Although it is lucky that wet rot does not have an impact on brickwork, in the worst case, you may need to have a new roof (very expensive!) if the timbers of your roof become structurally unsound. If a black fungus starts to appear on your woodwork and the roof timbers feel "spongy" to the touch, you may have an issue with wet rot.

Simple actions like examining pipework for leaks, repointing dodgy brickwork and cleaning and checking your gutters and roof for leaks, are the basic preventative maintenance measures. As part of an overall damp proofing program, your local Stevenage damp proofing company will check all of these factors.


Condensation Damp Stevenage UK (01438)

A common form of damp in many houses in Stevenage, condensation is extremely easy to spot. Tiny water droplets form on cold surfaces when they make contact with warm, moist air. It's often caused because of inadequate ventilation in areas where high humidity is present, i.e. kitchens, bathrooms and boiler rooms.

Easy solutions to prevent condensation involve wiping up any water droplets as they form and making sure there is sufficient ventilation in the main problem areas. The necessary steps may involve the installation or upgrade of cooker hoods, air bricks and extractors, with the intention of redirecting moist air to the outside of your property in Stevenage.

There may be issues with sucking in damp air from outside, and by carrying out a detailed damp proofing survey an expert in Stevenage will identify circumstances that play a role in the situation. To effectively control condensation, airflow must be regulated properly. A knowledgeable Stevenage damp proofing specialist will gladly offer solutions and advice to accomplish this in your home.

Damp Proofing Quotes in Stevenage Hertfordshire


Homes constructed since 1875 in Great Britain have been required to have a damp proof course or membrane to be fitted as standard. You might not have a damp course installed on your home in Stevenage if it was built earlier than this. If you're experiencing rising damp in a house built after this date it might be that your damp proof course or damp proof membrane has been damaged somehow.

It can be rather difficult to distinguish rising damp, nevertheless some giveaway signs are; white powdery deposits being found on floor surfaces or forming on walls, "tide marks" on walls and rotten or crumbling skirting boards. It is plausible that you could have a rising damp problem if you have spotted one or more of these in your property.

Rising Damp Stevenage Hertfordshire

Merely checking your exterior walls to find out if you've got a DPM can be one step towards solving your rising damp problems. For adequate protection it ought to be 150mm (about 6") above the level of the ground. If you find that this gap doesn't exist, you can dig the ground away to increase it, or if this process is not possible, a higher damp proof membrane (DPM) will need to be installed.

If this is not the root cause of the problem and your damp proof membrane (DPM) is in order, there may be more problematic issues to deal with caused by the dampness coming up from the ground beneath, up through your floor, and into your walls.

Stevenage damp proofing specialists will swiftly be able to establish the cause of your rising damp, and employing a variety of procedures will quickly solve the problem. Older homes which either have no DPM, or have a compromised one that's damaged over a wide area, can be treated with a damp proof injection cream such as Dryzone. Evenly spaced holes are drilled at intervals along the mortar joint, and a nozzle is used to inject the special cream, which then penetrates into the surrounding brickwork before curing to form an effective, horizontal water-repelling barrier.

If the damp proof cream treatment is not suitable, or the damage is too extensive to your membrane, a brand new damp proof course might have to be installed. This is taking repair work to the extreme, but it might be the only answer to your rising damp issues.

Painting with a bitumen based, waterproof latex emulsion, is yet another potential remedy for minimal areas of damage. Because this is going to be applied underneath your floor coverings, tiles, wood flooring and carpeting will have to be lifted before this operation can commence. In basement areas this is a particularly effectual treatment, and will form an integral part of the tanking process that is used to make rooms watertight. Before the bitumen paint has has dried out completely, your Stevenage damp proofing technician might suggest a layer of building paper (a foil backed specialist membrane), for further protection.

Tanking: The process of coating exposed surfaces with a waterproof paint in a cellar or below ground area is called "tanking". This must be applied on the base surface of walls and floors, therefore any plaster and wall coverings must be removed and the pertinent surfaces properly prepared before any work begins. As soon as this coating has been applied, it must be allowed to dry completely before replastering and decorating over the top of it. This is an incredibly disruptive process since it needs to be applied to a whole ground floor or basement level of a building, and it is preferable to obtain more than one expert opinion about whether this is the only treatment for your rising damp.


Condensation problems can certainly be helped through the use of dehumidifiers, which are an efficient way of lowering the moisture content in the air. Owing to the fact that dehumidifiers just hide the cause of the damp and not cure it, there are downsides to this solution. A professional damp proofing specialist in Stevenage will be able to offer advice on the best solution if you are experiencing damp or mould in any area of your home.


As with pretty much any project, the best recommendations for a specialist can be obtained from neighbours and friends. Always get at least three different quotes from a variety of companies, and if you are in any doubt you should ask to see qualifications and professional memberships, before hiring any damp proof services.

Keep an eye out for contractors holding the CSTDB (Certificated Surveyor of Timber and Dampness) or the Certificated Surveyor in Remedial Treatments (CSRT) qualifications, or companies who are signed up members of the Property Care Association (PCA) or the Damp Proofing Association.

You can guarantee that your damp proofing provider is suitably qualified and has acquired the necessary working experience to provide a top notch damp proof service, if they are members of either the DPA or PCA. It also offers guarantees on any work supplied by one of their members.
