Selling a property is rarely straightforward, especially when there are potential structural concerns involved. One of the biggest issues that can arise when selling is underpinning. Underpinning is a method used to strengthen the foundations of a property that has experienced subsidence or instability. While it is a vital structural repair, many homeowners worry about how underpinning will affect their property’s value and whether it will make selling more difficult.
In this in-depth article, we’ll explore everything you need to know about underpinning: what it is, how it impacts property value, how buyers view underpinned homes, and, most importantly, what your options are if you want to sell. At SELLTO, we understand how challenging it can be to sell a home with structural issues, which is why we offer a faster, hassle-free alternative for homeowners who don’t want to face the stress of redecorating, repairing, or explaining underpinning to cautious buyers.
What is Underpinning?
Underpinning is a construction technique used to stabilise and strengthen the foundations of a building. It is usually required when a property’s existing foundations are no longer strong enough to support the structure due to issues like soil movement, subsidence, or poor initial construction. Subsidence occurs when the ground beneath a property shifts, causing the foundations to sink unevenly. Signs of subsidence include cracks in walls, sticking doors and windows, and sloping floors.
Underpinning can be carried out using several different methods, including:
- Mass concrete underpinning: The traditional method where sections of the foundation are excavated and filled with concrete.
- Beam and base underpinning: Concrete beams are installed under the foundation to distribute weight more evenly.
- Mini-piled underpinning: Steel piles are driven deep into the ground to reach stable soil, often used where access is limited.
While underpinning is effective at addressing structural concerns, it is also one of the most dreaded words in the property market because of the stigma it carries.
Does Underpinning Devalue a Property?
The short answer is: yes, underpinning can affect a property’s value. However, the extent of the impact depends on multiple factors, including the cause of the underpinning, the quality of the work, and how buyers perceive the risk. Let’s break it down:
- Buyer Confidence
Buyers can be cautious about purchasing a property with a history of underpinning because it suggests that the property had structural issues in the past. Even if the issue has been resolved, the stigma alone can reduce demand. - Mortgage Lender Concerns
Many lenders are hesitant to approve mortgages on underpinned properties. If they do, stricter conditions or higher interest rates may apply. This limits the pool of buyers, as fewer people can secure finance. - Insurance Costs
Insurance premiums are typically higher for underpinned properties, and some insurers may even refuse coverage. This can deter potential buyers who don’t want the ongoing financial burden. - Market Value Impact
The reduction in value can range from 10% to 25% or more, depending on the severity of the underpinning history, location, and local demand. In some cases, properties in high-demand areas may not lose as much value, while in slower markets, the effect can be significant.
The Stigma of Underpinning
The key challenge is not just the physical repair but the perception of underpinning. Even when work has been completed to the highest standards, the word itself raises red flags. Buyers often imagine ongoing structural problems, even when the issue has been resolved. For sellers, this creates added stress:
- More questions during viewings.
- Longer negotiations.
- Lower offers.
- Sales falling through at the survey stage.
The reality is that underpinning often makes a property structurally stronger than before, but the stigma is difficult to overcome in the eyes of the market.
Selling an Underpinned Property: Challenges
1. Disclosure Obligations
As a seller, you are legally required to disclose if your property has been underpinned. Failing to do so could lead to legal consequences later.
2. Limited Buyer Pool
Cash buyers may be your best option, since many mortgage lenders hesitate on underpinned properties. But this means fewer offers and less competition.
3. Prolonged Sales Timeline
Even interested buyers may take longer to commit, as surveys, insurance quotes, and lender approvals all take time.
4. Lower Valuations
As mentioned, expect a reduction in value compared to similar homes without underpinning history.
Case Study: Selling a Home with Underpinning
Consider a semi-detached home in the Midlands that had experienced subsidence due to nearby tree roots. The property was underpinned professionally ten years ago, and the work was certified. When the owners decided to sell, they faced the following challenges:
- Multiple buyers withdrew after surveys highlighted the underpinning.
- The asking price had to be reduced by nearly 20% to attract serious interest.
- Even after accepting a lower offer, the sale took over a year to complete.
This example highlights why many homeowners find selling an underpinned property both stressful and financially frustrating.
What Are Your Options if Your Property Has Been Underpinned?
1. Sell on the Open Market
You can list the property with an estate agent. However, be prepared for lower offers, slower sales, and a potentially drawn-out process.
2. Rent the Property Out
Some homeowners choose to rent rather than sell, avoiding the immediate value loss. However, this means becoming a landlord, dealing with tenants, and managing insurance challenges.

Conclusion: Underpinning and Property Value
So, does underpinning devalue a property? The reality is that underpinning often does reduce market value due to buyer perception, limited mortgage availability, and higher insurance premiums. While the repair itself can make a home structurally stronger, the stigma attached to underpinning makes selling more complicated.
For homeowners who want to achieve a fast, certain sale without the stress of explaining underpinning to nervous buyers, SELLTO is here to help. We buy homes in any condition, meaning you can move on quickly and confidently without the weight of structural history holding you back.
Final Thought: Underpinning doesn’t mean your property is unsellable – but it can make selling on the open market harder and less profitable.
