Basically, when considering damp in the home there are three fundamental problem areas:

Damp Proofing Chelmsford Essex (CM1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


These three key types of damp are reviewed in greater detail in the following paragraphs, along with recommendations for prevention and resolution, should you find them in your house in Chelmsford.


There are numerous exterior factors that can lead to penetrating damp, and included in these are: cracks in brickwork, loose or cracked roof tiles, defective guttering or drainpipes and cavity wall issues. Inside your dwelling, it can also be caused by leaking or burst pipes, overflowing baths or sinks and cracked shower trays. If left unresolved, broken or blistered plaster, damp, dark patches on walls and flaking paintwork, will be the visible upshot of water soaking into the walls and woodwork.

Roofing timbers that are continually damp because of a leaking roof, can get wet rot if this isn't dealt with. Whilst it doesn't spread into the brickwork, wet rot can cause your roof timbers to become structurally dangerous, and in a worst case scenario you could even need to get a new roof - very expensive! A musty, unpleasant smell of rotten wood, the appearance of black fungus, and a "spongy" feel to your roof timbers, are all indicators that wet rot is already a problem.

Some basic maintenance measures can help to prevent this, such as: repointing brickwork, examining pipes for leaks and cleaning and checking your roof & gutters for leaks. A professional damp proofer in Chelmsford will check all these areas to help prevent any further problems, as an element of fixing your damp issues.


Condensation Damp Chelmsford UK (01245)

Many dwellings in Chelmsford have problems with condensation, and this is one of the most common factors that cause damp. When colder surfaces come into contact with warm, humid air, minute water droplets form on those cold surfaces. It often manifests due to poor ventilation in places where there's high humidity, i.e. kitchens, boiler rooms and bathrooms.

Wiping away any water droplets that appear, and ensuring that you have enough ventilation in the main trouble spots, are amongst the simplest answers to such issues. The steps needed may require the installation or updating of air bricks, cooker hoods and extractors, with the intention of redirecting damp air outside of your home in Chelmsford.

A damp proofing survey by a reliable Chelmsford specialist may also find factors which bring about the issue by drawing in moist air from the outside. To effectively control condensation problems, airflow has to be properly regulated. An experienced Chelmsford damp proofing specialist will be able to offer solutions and advice in connection with this.

Damp Proofing Quotes in Chelmsford Essex


Houses constructed since 1875 in Great Britain have required a damp proof course or membrane to be installed as standard. You may not have a damp course installed on your home in Chelmsford if it was built prior to this period. If you are suffering with rising damp in a home built after this time it may be that your damp proof course has been damaged somehow.

Rising damp can be hard to distinguish, but some areas to look out for are; a white powdery deposit being found on floor surfaces or appearing on walls, crumbling or rotten skirting boards and "tide marks" on walls. Although the existence of these is not conclusive, they're all indications of rising damp issues.

Rising Damp Chelmsford Essex

The first step towards solving your rising damp problems should be to simply check whether you've got a damp course on the exterior walls of your property in Chelmsford. It ought to be 150mm (approximately six inches) above ground level for adequate protection. You can dig the surrounding soil away to generate this gap if it's currently not sufficient, or you could install a higher damp proof membrane (DPM) if the first option isn't possible.

If this is not the cause of the problem and your damp course is in fact correct, there could be more challenging issues to deal with caused by the moisture coming up from the ground, up through your floors, and into your walls.

Using a number of different procedures, damp proofing professionals in Chelmsford can swiftly identify and eliminate rising damp. If you have an older house with no DPM or one that is damaged over a considerable area, a damp proof cream (such as Dryzone or Permaguard) can be carefully injected into your outside walls. This calls for the drilling of holes at evenly spaced intervals into your brickwork and the special cream injected with a nozzle to plug the spaces behind the brickwork.

In cases where damp proofing cream injection isn't a satisfactory treatment, or when the membrane is seriously damaged, installing a new damp proof course could be neccessary. While this level of repair work is a fairly drastic way to solve rising damp issues, it may be the only real solution in the end.

Painting with a waterproof (bitumen based) latex emulsion, is another potential remedy for smaller areas of membrane damage. Since this is applied underneath your existing floor coverings, carpets, wood flooring and tiles must be lifted and removed before this process can begin. In cellars this is a particularly effective solution, and will form a part of the "tanking" procedure which is used to create watertight spaces. Before the bitumen paint has dried completely, your Chelmsford damp proofing technician might recommend the use of building paper (a special foil backed membrane), for further protection.

Tanking: The process of covering exposed surfaces with a watertight paint in a cellar or below ground area is known as "tanking". Any wall coverings and plaster must be taken off and the surfaces in question prepared properly before any work begins, because this watertight coating has to be applied on the base surface of floors and walls. As soon as the paint has been applied and dried, it is then possible to replaster the walls and decorate over the top of it. This is a very disruptive job since it has to be applied to an entire ground floor or basement level of a building, and it's advisable to get more than one specialist opinion about whether this really is the only solution to your rising damp issues.


Dehumidifiers are a highly effective way to remove moisture from the air, hence for condensation problems they can help. The fact that these gadgets only hide the cause of the damp and not cure it, is the main problem with dehumidifiers. To obtain the most reliable advice if you are experiencing dampness in any area of your house, you should contact a professional damp proofing specialist in Chelmsford.


The most reliable recommendations for professionals when it comes to home improvement projects are normally friends and family. Always obtain at least 2 or 3 different quotes from a variety of companies, and if you have any doubts you should ask to see evidence of qualifications and professional memberships, before signing up to any damp proof services.

Keep an eye out for membership of and qualifications from organisations such as the Property Care Association (PCA) or the DPA (Damp Proofing Association), or contractors holding the CSRT (Certificated Surveyor in Remedial Treatments) or the CSTDB (Certificated Surveyor of Timber and Dampness) qualifications.

If your chosen Chelmsford damp proofing providers are members of either the DPA or PCA you can be certain they'll be well qualified and have the required experience to provide you with a high quality service for your damp proofing issues. Additionally, it offers guarantees on any remedial work performed by one of their members.
