How to Deal with Damp in Commercial Property?

prevent damp in a commercial property

Damp in commercial properties is one of those pesky problems that many of us hope to avoid but, unfortunately, it’s a reality for many property owners and managers.

It doesn’t matter whether you’re a letting agent, a landlord, or a construction company, damp is a sneaky menace that can crop up anywhere. From unassuming walls to underfloor areas, damp has a habit of showing up uninvited and wreaking havoc.

When left unchecked, it can lead to structural issues, impact the health of those using the property, and ultimately hit you in the wallet with costly repairs.

For those who are managing commercial properties, having an awareness of damp is crucial, not just because it’s a major concern, but also because it can affect the overall value and usability of the property.

Below, we will explore how to address damp issues in commercial properties.

Types of Damp in Commercial Property

When it comes to damp in commercial properties, there isn’t just one type of problem to watch out for. In fact, there are three main types of damp that you’ll need to consider: condensation, rising damp, and penetrating damp.

Each type comes with its own set of challenges and requires different solutions. Let’s break these down and see what we’re dealing with.

Condensation

Condensation is one of the most common forms of damp, especially in commercial properties that have a lot of activity, think offices, shops, or restaurants. This type of damp occurs when warm, moist air comes into contact with a cold surface, like a window or a wall.

The moisture in the air condenses into water droplets, which then lead to damp patches, mould growth, and general mustiness. For property management companies, this can be a serious headache. Not only does condensation damage the building, but it also creates an unhealthy environment that might deter tenants or customers.

Preventing condensation involves maintaining good ventilation throughout the property, using dehumidifiers if necessary, and ensuring that rooms are heated properly. It’s all about striking that balance between warmth and airflow.

Rising Damp

Now let’s talk about rising damp. This occurs when moisture from the ground finds its way up through the walls of your property. This happens most often when the damp-proof course (a kind of barrier built into the property) fails or is missing.

Rising damp is typically identified by tide-mark-like stains on walls, peeling wallpaper, and a musty smell that can linger throughout the property. For commercial properties, rising damp can compromise the structure and also make it quite an unpleasant space for tenants and workers alike.

For property managers, ignoring rising damp can lead to severe issues, including rotting timbers and crumbling plaster, essentially, the bones of your building could be at risk. Addressing rising damp usually requires professional intervention, like injecting damp-proof chemicals or installing a new damp-proof membrane.

Penetrating Damp

Finally, we have penetrating damp. Unlike rising damp, penetrating damp occurs when water gets through the walls from the outside. This can happen due to damaged brickwork, faulty gutters, or leaky roofs. Penetrating damp is most noticeable during or after periods of heavy rain, and it’ll often manifest as damp patches on the ceilings or walls.

This type of damp is particularly problematic for property management companies, as it can cause damage to the property’s interior decoration and may even affect the tenants’ belongings.

To fix penetrating damp, it’s essential to locate and repair the source of the water ingress, be it a broken gutter or a cracked wall, as quickly as possible to prevent more damage.

Finding a Damp Problem

Spotting damp early can make all the difference. If you’re a letting agent or property manager, consider developing a damp checklist for your properties. Here’s a quick guide to identifying potential damp issues:

  • Look for mould or mildew on walls, particularly in corners or around windows.
  • Check for peeling wallpaper or paint, especially around skirting boards.
  • Pay attention to musty smells, they often signal hidden damp.
  • Inspect external walls for cracks or leaks.
  • Look for water stains or tide marks on walls and ceilings.
  • Check under flooring if possible, especially in basements or ground-level rooms.

By being proactive and carrying out regular inspections, you can spot problems early on, saving both time and money in the long run.

Whose Responsibility is Damp in a Commercial Property?

Damp in commercial properties is a shared responsibility, but understanding exactly who is liablecan be a bit of a grey area.

Typically, the obligations depend on the lease agreement, and it’s crucial for both landlords and tenants to understand where their responsibilities lie.

Understanding Your Landlord’s Obligations

In the UK, landlords are bound by law to ensure that the properties they let are fit for purpose and safe for occupation.

Under the Landlord and Tenant Act 1985, landlords are obligated to maintain the structure and exterior of the property, which includes dealing with any damp caused by issues like leaking roofs, cracked walls, or faulty damp-proofing. If the damp is a result of such structural issues, then it’s usually up to the landlord to sort it out.

Your Landlord’s Duty to Repairing Damp and Mould

On the flip side, if the damp is caused by something like poor ventilation or condensation due to the tenant’s use of the property (for example, inadequate heating or drying clothes indoors without ventilation), then it might be considered the tenant’s responsibility.

For landlords and property managers, maintaining a clear communication channel with tenants is key to ensuring any damp issue is dealt with promptly, before it turns into a costly repair.

Damp is a persistent problem in many commercial properties, but it’s not unbeatable. From understanding the different types of damp, condensation, rising damp, and penetrating damp, to knowing how to spot the warning signs, being informed is the first step to keeping your property safe, sound, and damp-free.

Whose responsibility it is to fix the problem can vary, but ultimately, ensuring the property remains in good condition is in everyone’s best interest.
