Subsidence
At the heart of our journey lies the trust of thousands of businesses worldwide, reflected in the numbers that drive us forward.
What is subsidence?
Subsidence is the gradual downward movement of the ground beneath a building, causing the foundations of the building to become unstable and the property begins to sink down as a result
Subsidence affects tens of thousands of UK residents every year, devaluing their property and compromising its structural safety. It also impacts warehouses, factories and other commercial and industrial buildings. Highways, roads, airport runways, sea walls and harbours and other infrastructure can be critically impacted by subsidence.
Generally, subsidence is not an overnight occurrence, it can take many years for it to show any effects on structures. The visible signs at the start are usually small and some property owners may believe it’s something that can be addressed later. Unfortunately, this is never the best option. Subsidence is best dealt with as early as possible to minimise the work that must be carried out during the repairs.
Ignoring subsidence can have a wide variety of knock-on effects depending on what you use your property for. Landlords may struggle to rent out a property that has subsidence, as tenants want to feel secure in the home that they live in. People looking to sell their house will struggle to sell a house that has subsidence for the same reasons.
If you’re looking to continue living in the property, subsidence can also cause serious structural damage in the long term, and in the worst cases, can cause complete collapse of the property.
How To Fix Subsidence?
Historically, one of the few options for fixing subsidence was concrete underpinning. This was a costly, timely and messy procedure that included excavating the ground beneath your property and supporting the foundations with large volumes of concrete. Anyone living in the property at the time would have to move out, which could put families without a home for an extended amount of time, or a landlord without rental income.
Luckily, modern technology enables us to fix subsidence much more efficiently and much more cost effectively. Modern resin injection methods can be used to successfully strengthen the ground and re-level and repair homes affected by subsidence in significantly less time than it takes for traditional concrete underpinning. In the majority of cases, the occupants don’t need to move out!
Mainmark’s Teretek® resin injection solution is a proven, cost-effective and quick alternative to more invasive methods. Using a process similar to keyhole surgery, the work can often be completed in one day. It is widely used to strengthen foundation ground, re-level buildings and remediate issues in residential, commercial, industrial, mining and infrastructure projects.
How does subsidence affect house sales?
For many, purchasing a property is the biggest investment of their life. The buyer and the seller will want a smooth process, however, there will often be a need for compromise.
For sellers, the final sale price is typically the biggest compromise, while buyers usually need to be flexible regarding the location, layout and size. However, expensive structural repairs may be a deal breaker for many house hunters.
If you’re buying a house and you suspect that it has subsidence, then you should have a full building survey done, this should inform you if there is any risk of subsidence. If subsidence repair work has taken place in the past, then you should obtain documents from the seller to verify that repairs were done to the standard set out by the Building Research Establishment. These documents should include:
A formal completion certificate (issued by the council).
A certificate of structural adequacy.
There may be some guarantees within these repair documents that you will want passed on to you. It’s also a good idea to find out more about the insurance for the property, as properties with a history of subsidence may have limited or more expensive policies.
If you’re selling a house that has subsidence or has a history of subsidence, transparency is key. You may also have to be prepared to lower your asking price; a 2021 report by SOLD.co.uk found that houses affected by subsidence saw a valuation decrease of 20% – 25%.
Sellers should remember that having subsidence on a property does not mean that it can never be sold! Your property will have many positives that you should look to promote and if the work has been completed to the appropriate standard, it is only a matter of time until a buyer is found.
What are the signs of subsidence?
Our dedicated team of experts is committed to understanding your unique needs and objectives, working closely with you to develop and execute.
Cracks in walls
The most common sign of subsidence is cracks appearing in internal and external walls. Cracks are a mechanism for releasing stress in a structure, which naturally weakens your property’s design. It’s important to note that not all cracks mean that your house is suffering from subsidence, small cracks are often just cosmetic and could purely be down to the age of the property.
Jammed doors and sticking windows
Subsidence cracks often appear near doors and windows, as these weaker points are more prone to movement. Depending on their position, cracks may cause gaps around frames, doors or windows swinging open on their own, or making them jammed and difficult to open or close.
Sinking floors
Sinking floors are often the most obvious signs of subsidence, but it’s still important to keep your eye out as it’s best to catch it as early as possible! Sinking floors can form in different ways, if the subsidence is concentrated in the middle of the property, then the centre of the floor can indent or “dish”.
