We'll look at these three significant sorts of damp problems, and come up with tips on how to prevent them and resolve them, should they come about.


Problems like blocked cavity walls, cracked roof tiles, damaged or porous brickwork and damaged downspouts or guttering are common external factors that can lead to penetrating damp. From within, it can be created by burst or dripping pipes, cracked shower trays and overflowing sinks or baths. If water is allowed to continue soaking into the walls and woodwork, the obvious signs with time are going to be peeling or bubbling paintwork, dark, damp patches on walls and broken or blistering plaster.

If you've got a leaking roof that's been neglected for a while, the timbers of your roof can be troubled by wet rot. This could prove to be really expensive, because in the worst case scenario your roof timbers become structurally unsound, with the result that you'll need a whole new roof. Wet rot can be recognised by black fungus appearing on your woodwork and a "spongy" feel to the rafters, coupled with an unfamiliar musty smell from the rotting wood. When any of these wet rot signs are noticed, it's vital to deal with the issue promptly to prevent further harm and the potential need for costly roof replacement.

The means of prevention can be quite basic, for instance examining pipes for leaks, cleaning and checking your roof & gutters for leaks and repointing brickwork. A certified Northwood damp proof specialist will check all of these areas in order to help avoid any further complications, as part of resolving your issues with damp.

Damp Proofing Quotes in Northwood Greater London


Since 1875, a damp proof course has been installed as standard in all homes constructed in Great Britain. You may not have a damp proof course on your property in Northwood if it was built prior to this period. If your home was constructed after this date, but you're still experiencing rising damp, it may be that the damp proof course has been damaged.

If you suppose that you might have rising damp, "tide marks" on walls, rotten or crumbling skirting boards and a white powdery deposit forming on walls or being discovered on floor surfaces, are fair indications that you might be correct. It is plausible that you might have a rising damp problem if you have seen one or all of these.

Rising Damp Northwood Greater London

Simply checking your exterior walls to spot if you've got a damp proof course can be one step towards managing your rising damp problems. It needs to be 150mm (around 6") above the level of the ground for adequate protection. You could dig the surrounding ground away to create this gap if it is currently not sufficient, or you could install a higher DPM (damp proof membrane) if the former is not possible.

You may have more challenging issues if you discover that your damp proof course is OK, and it might be that the moisture is creeping up from the ground, through your flooring, and into the walls, which can be an even more worrying situation.

Damp proofing specialists in Northwood will swiftly detect and remedy rising damp using a number of different procedures. If you have an older house with no DPM or one that is damaged over a significant area, a damp proofing cream (such as Permaguard or Dryzone) can be carefully injected into your external walls. This special cream is injected with a nozzle into holes drilled evenly along the wall's mortar course, and before the cream sets it diffuses into the surrounding brickwork creating a barrier that is water-repellent.

If the deterioration of the damp course membrane is too extensive, or if damp proofing cream is not an appropriate solution, you might have to put in a brand new damp proof course. This is the most extreme of repair works, however it could be the only remedy for your rising damp.

Yet another solution for smaller areas of damp course damage may include painting on a layer a waterproof (bitumen based) latex emulsion. Wood flooring, carpets or tiles will have to be lifted before any work is undertaken, as it's applied beneath your existing floor coverings. In cellars this is a particularly effectual treatment, and will form an integral part of the tanking process that's used to create watertight spaces. Before the bitumen paint has dried completely, your Northwood damp proofing technician may suggest the laying of building paper (a foil backed specialist membrane), for additional protection.

Tanking: Waterproofing basements, cellars or below-ground spaces through "tanking" involves applying a special kind of watertight paint on exposed surfaces. To do this effectively, removing all existing plaster and wall coverings is a prerequisite, ensuring the waterproof paint adheres directly to the base of the walls and floors. This critical step creates an essential barrier against moisture. The applied coating must then be thoroughly dried before any replastering or decorative work can commence. Tanking, an intensive process, requires the treatment of the entire lower level of a property, hence consulting several damp proofing companies is advisable to ascertain if it is the best course of action for your specific damp problems. Other less invasive yet potentially effective methods should be considered, given the invasive nature of tanking.


Condensation issues can definitely be helped by the use of dehumidifiers, which are an efficient way to remove moisture from the air. Owing to the fact that dehumidifiers primarily mask the cause of the damp and not get rid of it, there are issues with this solution. If you're experiencing mould or damp in any part of your property in Northwood, you should contact a competent damp proofing company for the most reliable advice.


The most reliable recommendations for specialists when it comes to home improvement projects are usually family and friends. Before employing any damp proofing services, you should try to obtain at least 2 or 3 estimates from a variety of Northwood companies. If you're in any doubt about any particular damp proofing company you could ask to see evidence of professional memberships and qualifications.

Dehumidifier Installation

To maintain healthy and comfortable indoor air quality, particularly in high humidity spaces, dehumidifiers are a must-have appliance. Proper installation is crucial for the optimal longevity and performance of the unit.

Woodworm Treatment and Prevention in Northwood

Woodworm infestations are quite common in Northwood, particularly in older buildings. The woodworm larvae feed on wood, weakening structures and causing damage over time. If left unresolved, woodworm can cause serious damage to the structural integrity of buildings. Luckily, woodworm treatment options are readily available available in Northwood.

The starting point of treating woodworm is to determine the type of woodworm present, since different species require different treatment methods. This is best done by a woodworm specialist, who can also evaluate the extent of the infestation and propose the most suitable treatment method.

This method is best suited to minor infestations, and a professional can determine whether this is the best option. For more severe infestations, fumigation may be necessary. This involves sealing the affected area and releasing a gas into the space to kill off the larvae. Fumigation is a more invasive treatment, however for large infestations, it is generally the best option.

To prevent future woodworm infestations, it is critical to ensure that the environment is not conducive to their growth. This can be achieved by maintaining appropriate humidity levels, proper ventilation, and treating any existing woodworm as soon as it is identified.

Regular checks of the property can aid in the prompt detection of infestations of woodworm, thus mitigating harm. Furthermore, it is crucial to deal with any water damage because damp wood can be a magnet for woodworm. In the event that you have wooden furnishings or items in your house, it is important to keep them free from moisture and well-maintained to prevent infestations of woodworm.

Condensation Control

A crucial element in maintaining a pleasant and healthy indoor environment is the control of condensation. The contact between cooler surfaces and warm, moist air causes the formation of water droplets through condensation. Uncontrolled condensation can result in mould growth, damage to building materials, and the deterioration of indoor air quality.

Condensation Control Northwood

Effective control of condensation necessitates good ventilation, which regulates humidity levels and facilitates air circulation. Reduction of condensation and differences in temperature can be attained by using double-glazed windows and insulation. Effective condensation management enables the prevention of potential issues and the creation of a more pleasant working or living environment.

Insulation and double-glazed windows can be used to help minimise temperature differentials and reduce condensation. Insulation prevents cold surfaces and warm, moist air from touching each other by serving as a barrier. Condensation is less likely to form on surfaces like walls, ceilings and windows when there is a reduction in temperature difference. Condensation is further inhibited by double-glazing, which features 2 panes of glass with an insulating layer in between and is effective at maintaining an even interior temperature.

To control condensation effectively, another technique is to address moisture sources head-on. Drying clothes indoors, showering and cooking and similar activities can all release moisture into the air and cause problems. Exhaust fans and good ventilation in kitchens and bathrooms can prevent an excessive build-up of humidity. Optimal indoor humidity levels can be maintained in areas which are liable to high moisture content by using dehumidifiers.

A more pleasant working or living environment can be created by effectively dealing with condensation and preventing potential problems. The well-being and health of occupants, as well as the structural integrity of buildings, can be safeguarded by controlling the indoor environment. Regular maintenance checks, including examining seals around windows and doors for gaps, can help you identify locations where condensation is likely to occur. The emergence of new condensation control technologies and strategies, driven by advances in building science and indoor air quality understanding, provides even more effective ways to ensure a healthy and comfortable indoor environment. To conclude, the implementation of proper ventilation, insulation, moisture source management, and cutting-edge technologies are all vital components of a comprehensive condensation control strategy.
