Damp Proofing Welwyn Garden City Hertfordshire (AL7)


  • Penetrating Damp

  • Condensation

  • Rising Damp


Below you will find details of what could cause damp problems in your home in Welwyn Garden City, and precisely how you might go about rectifying them.


Penetrating damp in the home can be attributable to various external factors for example: unsound brickwork, damaged guttering, cavity wall problems and loose or broken roof tiles. Inside your Welwyn Garden City home, it can result from damaged shower trays, overflowing sinks or bathtubs and burst or leaking pipes. If left uncontrolled, broken or blistering plaster, damp dark patches on walls and flaking or bubbling paintwork, will be the obvious signs of water seeping into the woodwork and walls.

If you have a leaky roof and it's been left untreated for an extended period of time, it can cause wet rot to develop in your roof timbers. Wet rot does not spread into your brickwork, but having it can mean that in the worst outcome the timbers of your roof become structurally unsafe, necessitating a new roof. Wet rot can be identified by black fungus appearing on your woodwork and a "spongy" feel to the timbers, along with an unusual musty smell from the rotting wood.

The measures for prevention can be pretty basic, for instance examining piping for leaks, repointing brickwork and cleaning and checking your roof and guttering for leaks. As an integral part of an overall damp proofing package, your local Welwyn Garden City damp proofing specialist will check all these areas.


Condensation Damp Welwyn Garden City UK (01707)

Condensation is extremely easy to identify and a common form of damp in many homes in Welwyn Garden City. When cooler surfaces make contact with humid, warm air, minute water droplets appear on those surfaces. Poor ventilation in places with a high level of humidity, such as in kitchens, boiler rooms and bathrooms, is the most common reason behind condensation.

Easy strategies to stop condensation involve wiping up any droplets as soon as they appear and ensuring you've got adequate ventilation in the main problem areas. Redirecting moisture laden air outside of your property in Welwyn Garden City, by updating or fitting air bricks, cooker hoods and extractors, will help you to resolve this issue.

A damp proofing survey by a reliable Welwyn Garden City specialist might also find areas which contribute to the situation by sucking in damp air from outside. To effectively control condensation problems, airflow needs to be properly regulated. A professional Welwyn Garden City damp proofing company will be able to offer advice and solutions in regards to this.

Damp Proofing Quotes in Welwyn Garden City Hertfordshire


Homes built since 1875 in Great Britain have been required to have a damp proof course or membrane to be fitted as standard. You may not have a damp course on your home or property in Welwyn Garden City if it was built earlier than this. It is possible that your damp proof course or damp proof membrane may have been damaged somehow if you are suffering with rising damp problems in a home built after this date.

Rising damp can be notoriously tricky to identify, but some things to keep an eye out for are; crumbling or rotten skirting boards, "tide marks" on walls and white powdery deposits being discovered on floor surfaces or forming on walls. Although the existence of one or more of these is not conclusive, they're all clear indications of rising damp issues.

Rising Damp Welwyn Garden City Hertfordshire

Solving rising damp problems can be as easy as checking your exterior walls and seeing if you can spot a damp proof course. It needs to be 150 millimetres (around six inches) above ground level for satisfactory protection. You can dig away the surrounding earth to generate this space if it is currently not sufficient, or you can install a higher DPM (damp proof membrane) if the former isn't feasible.

If your damp course is in order and the gap from the ground is not the root cause of the problem, moisture could be coming up through your flooring and into your walls, which could be a much more problematic issue.

Using a number of different methods, damp proofing professionals in Welwyn Garden City can swiftly detect and remedy your rising damp problems. If you've got an older home with no damp proof membrane or it is damaged over a substantial area, a damp proofing cream (such as Dryzone) can be injected into your wall. This involves drilling holes at intervals along the brickwork and the special cream injected with a nozzle to fill the gaps behind the brickwork.

In instances where damp proofing cream is not an appropriate solution, or where the damp course membrane is severely damaged, putting in a new damp proof course may be neccessary. Although this is of course a pretty drastic course of action, it might be the only method to resolve your rising damp problems successfully.

The application of a bitumen based, waterproof latex emulsion, is yet another possible solution for minimal areas of damage. This is applied beneath your floor coverings, so carpets, tiles and wooden flooring will have to be lifted prior to work being done. In basement areas this is a particularly efficacious solution, and will form an integral part of the tanking process that is used to make rooms watertight. For further protection in such problem areas, your Welwyn Garden City damp proofing specialist might advise a layer of building paper (a foil backed specialist membrane) before the bitumen paint has has dried out completely.

Tanking: In basements and below ground areas of a property, tanking is a process where surfaces that are exposed are painted with a waterproof coating. As this waterproof coating has to be applied to the bare surfaces of floors and walls, all plaster and wall covering must be taken off before work begins, and the pertinent surfaces prepared properly. You can replaster any wall surfaces and decorate over the top, as soon as the coating has thoroughly dried out. This is an exceptionally disruptive job because it has to be applied to an entire ground floor or basement level of a building, and it's preferable to get more than one specialist opinion on whether this is really the only solution to your rising damp.


To help ease condensation problems, you could try using dehumidifiers, which for reducing the moisture content of the air, are very effective. The downside with dehumidifiers in endeavouring to reduce damp and mould is that they only mask the cause of the damp, don't cure it. A professional damp proofing specialist in Welwyn Garden City will be glad to give you advice on possible solutions if you're experiencing damp in any part of your house.


Friends and relatives should invariably be your first port of call when you're trying to get recommendations for local professionals. Before signing up to any damp proofing services, you should try to get at least two or three estimates from different Welwyn Garden City companies. If you have any doubts about any specific company you could ask to look at professional memberships and qualifications.

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

If your Welwyn Garden City damp proofing specialists are in fact members of the DPA or PCA they will be suitably qualified and have acquired the required practical experience to provide a first class service for your damp proofing issues. Such professional memberships also means there are certain guarantees for any work carried out.
