Commercial Damp Surveys

Whether you’re a building contractor or a property manager, you have a duty of care to provide individuals with buildings that offer a safe working environment. Under the Landlord and Tenant Act of 1985 commercial landlords need to make good repairs to the ‘structure and exterior of the dwelling’.

Understanding Identify and Fix Hidden Issues Before They Cost YouIssues

In commercial buildings the issues surrounding damp and mould can cause confusion over who is responsible for the problems. The tenant may blame the landlord for not providing adequate ventilation in the premises. In contrast, the landlord may lay the blame on the tenant for activities that create moisture or mismanaging the building to create damp problems. Either way, it is the landlord’s responsibility to deal with any damp issues, whether that is dealing with the repairs or educating the tenants on how to better manage the property.

It is now a legal requirement to have an EPC certificate for any commercial property. The soaring costs of energy have made the efficiency of any potential commercial premises of vital importance. Keeping commercial premises free from damp issues will aid the overall energy efficiency and considerably lower energy costs.

Advanced Damp Ltd are specialists in damp proofing services, which are designed to support commercial properties in maintaining structural health and safety. The specialist team conduct precise surveys and treatments across all commercial sectors, ensuring your property is protected and preserved. Advanced Damp Ltd are your guaranteed partner in safeguarding your commercial premises against damp, guaranteeing a healthier environment for all.

Understanding Damp Issues

What is Rising Damp?

When rising damp occurs it does what it says on the tin. Moisture, usually from the surrounding ground, enters the base of walls and rises through the brickwork using capillary action to make damp walls. Most building materials are porous to some degree, so the excess moisture finds an easy route upwards.

Over time, if there is no damp proof membrane to halt the movement of the water, internal and external walls and plasterwork can be severely affected. A damp proofing membrane treating rising damp is a standard part of all property construction now. However, some older buildings need remedial rising damp treatment to enable them to offer the same level of protection to internal walls from damp.

Similarly, some older buildings may have a damp proof membrane on the external wall that has deteriorated over time and needs specialist damp treatment to stop rising damp.

What is Penetrating Damp?

Penetrating damp is often caused by moisture moving through external walls to the interior through the brickwork. Usually, the moisture gains access to through the exterior walls as a result of structural issues, which may have slowly evolved over some time.

Typical issues include defective roof coverings, leaking rainwater pipes or old pointing. Masonry, render and pointing are all susceptible to physical and frost damage, as well as natural deterioration through age.

Once the water has migrated to the interior walls, it can easily cause extensive damage with symptoms such as black mould and local damp patches and staining.

What is Condensation?

Especially during colder months, it is common to see tiny droplets of water form on windows and walls when the surrounding air is humid, such as in a commercial kitchen. When warm air hits these colder surfaces, the moisture-laden air changes from vapour to water droplets, which gradually merge to make larger droplets. These larger droplets can then stream into puddles, creating damp problems.

Condensation is often localised, where the air carries more moisture due to nearby activities. For example, a commercial kitchen typically has several large pots boiling on a cooker as part of a daily routine. Although extractor fans will remove most of the steam, the atmosphere in the kitchen will still likely be humid, resulting in condensation on the cold surface of the windows.

In commercial properties, nearly 75% of all damp cases are caused by condensation. Out of rising and penetrating damp, this might seem the most minor; however, condensation is the root cause of serious damage and health problems through mould growth.

Causes of Damp Issues

Ineffective Damp Proof Course

Rising damp is a common symptom when a commercial building is constructed without a damp proof course, or the existing damp proof course has deteriorated. The damp proof course is made from a bitumen-coated membrane, forming a water-proof barrier in brickwork to stop moisture from rising.

Remedial work to treat rising damp is a cost effective treatment. It’s not practical to replace the damp proof course, as it is an integral part of the wall, but injecting a waterproofing agent through drill holes lower down on the wall is a viable alternative. It’s always best to treat rising damp early to minimise its effects.

Faulty Plumbing Issues

Even the smallest leaks and drips from taps, pipe joints and boilers can cause extensive damage to internal walls and floors. Over time, persistent water leaks will severely damage plasterwork, wood, paintwork and render. The knock-on damage is equally serious when mould growth threatens workers’ health in the building.

As part of building maintenance regular checks should be carried out to identify any water leaks promptly. These can then be quickly repaired before any lasting damage occurs.

Leaking Gutters

Commercial buildings are often larger constructions and consequently they have a large roof area. Rainwater runoff from the roof is considerable, and it needs to be managed efficiently with guttering to ensure it doesn’t threaten the fabric of the building’s walls.

When guttering breaks or becomes blocked with leaves, the water has nowhere to go and can frequently pour down the exterior walls. Over time, this enables the water to migrate through the walls, creating the symptoms of penetrating damp.

A regular visual check of how guttering is performing should be enough to highlight any issues with broken or blocked sections. A closer inspection will identify any problem areas, and these can be quickly and inexpensively repaired.

Cracked Rendering

Rendering is sometimes applied to the exterior walls of commercial buildings. It is made either from sand and cement or a specialist synthetic resin, similar to plaster. It is often painted with a protective render primer to reduce damp access.

The render forms a barrier, helping reduce maintenance and heating costs in winter. However, constant exposure to the elements makes it prone to breaking and cracking over time. Rainwater can access these cracks, leading to symptoms of penetrating damp.

Regular visual building checks should highlight any deficiencies in the render. Any sections needing repair need close inspection to assess the best method. Small sections can be cleaned with a wire brush and then rendered again, or for more extensive areas, it might be necessary to remove the existing render and start again completely.

Cold and Damp Spots on Internal Walls

Cold and damp spots can occur on internal walls for several reasons. They are created either by water penetrating through the walls or by condensation forming on a particularly cold patch of the wall. Often, it’s possible to identify a cold spot by placing the back of your hand over the suspected area. You will sense the brickwork is damp just by being close to it.

There are a number of causes of cold and damp spots:

1. Moisture Bridge. In buildings with cavity walls and a damp proof, such as office blocks, workshops, and blocks of flats, the metal ties builders fit between the two brick courses can act as a bridge enabling moisture to travel from the outer course to the inner one. During construction, mortar may fall on these ties and harden, creating a bridge for moisture to travel across.

Similarly, builders sometimes run wires, fixings or central heating pipes through the cavity wall as a convenient route. However, any of these can act as a bridge when covered with mortar, which enables moisture to gain access from the outer brick layer into the inner one.

2. Cavity Wall Insulation. If cavity wall insulation is not carried out as required then cold spots and temperature variations may result. If the insulation material isn’t filled to the correct height then gaps will be created which can result in condensation problems on internal walls.

3. Penetrating Damp. Any faults or cracks in the brickwork can make an easy route for water to gain access to the internal walls as penetrating damp.

Importance of Early Detection and Treatment

Consequences of Ignoring Damp Issues

In business, first impressions count so it is vital that the external fabric of your commercial unit is in the best condition when your visitors see it for the first time. Water overflowing from blocked guttering down an external wall isn’t going to inspire confidence in any of your visitors. Similarly, ensuring your workforce can carry out their duties in a clean and safe environment, free from damp and mould, will aid productivity.

Having checks in place to ensure any building faults are quickly identified and rectified will keep maintenance costs down long term, ensure the efficient operation of the commercial unit and provide a better working environment for all staff.

Benefits of a Commercial Damp Survey

1. Damp can have a profound effect on commercial properties. Commercial units often experience more temperature changes than centrally heated houses, which can exacerbate any existing damp problems. Damp can damage walls, render, plasterwork, as well as timbers and metal fittings, all of which are costly to repair.

2. Workforce Health. Employment law clearly states the requirements that the workforce should enjoy day-to-day. Damp and mould issues can seriously impact on individual’s health and the effects of lowered moral directly affect productivity.

3. Safety Standards. The cost of time off work and accident claims are a continual concern for management. A simple slip on a wet patch can easily escalate into a costly claim. So, minimising these threats is a vital part of maintenance.

4. Down Time. Shutting down production to enable major works is very expensive and creates hassle and disruption to all staff.

5. Repair Costs. Catching damp problems early is a much cheaper repair option. When left for extended periods further damage will result along with higher costs.

Commercial Damp Survey Process

How to Conduct a Commercial Damp Survey

A full survey is undertaken by an experienced damp surveyor. This will include numerous visual checks inside and outside, as well as with a moisture meter, which will give an indication of dampness in walls. The collected readings give the surveyor an overall moisture profile, which will identify particular areas of concern.

From the overall survey, the damp specialist will be able to create a report which is fed back to the property manager along with the recommendations for correcting the damp proofing and the cost. Acting in good time often pays dividends in the long term. Allowing problems to fester only causes further damage to building materials to occur and consequently higher bills.
