Broadly speaking, there are two main types of damp: penetrating damp and rising damp. Some surveyors also include condensation in the conversation, though technically this isn’t damp in the same way, as it’s caused internally rather than coming from outside the building.

Penetrating damp happens when water enters a building through a defect in its structure. Think of a leaking gutter or a faulty flashing – rainwater gets past the external surface and into walls or ceilings. During a building survey, our team investigates these issues fully, checking for the source and the extent of any damage.

Rising damp is a little trickier. It’s moisture that moves up a wall, usually from the ground, often working alongside penetrating damp. Commonly seen where external walls are in contact with soil, or in basements with high water tables, rising damp carries moisture through plasterwork. It can leave telltale “tide marks” or staining on internal walls. Typically, this moisture travels up to around 1 metre from the ground level.

Rising damp always involves some penetration from the outside, but tests – including salt analysis – can help differentiate groundwater rising through the walls from rainwater intrusion. This is part of the detailed defect diagnosis we carry out during building surveys.

Understanding the type of damp is just the first step. Correct diagnosis is essential before deciding on any repairs or treatment. Our surveyors are here to help with both building surveys and targeted defect investigations, ensuring you know what’s happening with your property and what action may be needed.

Understanding traditional construction

Buildings constructed before the mid-20th century were built with solid walls, lime-based mortars and breathable materials. They were designed to manage moisture naturally rather than trap it. Modern inspection assumptions can misinterpret how these structures perform, leading to unnecessary or harmful interventions.

An experienced surveyor knows how these buildings were intended to work. They can distinguish between normal, age-related movement or wear and actual defects that need attention.

Considering alterations and history

Most older buildings have been altered over time. Extensions, reconfigured layouts, and past repairs all affect current performance. A standard inspection might spot cracks or damp but fail to identify the underlying cause.

Surveyors familiar with older properties look beyond symptoms, considering the building’s history, materials, and previous works before advising on repairs or maintenance. This ensures recommendations are proportionate and appropriate.

Surveys tailored to the building

Older properties benefit from detailed, context-aware surveys. Buyers and owners need to understand which issues are typical, which require intervention, and which are risks that can be managed over time. Experienced surveyors provide this clarity, helping owners make informed decisions rather than reactive fixes.

Planning maintenance effectively

A proactive approach to maintenance is particularly valuable for older buildings. Early intervention for minor issues prevents costly repairs later. Combining building surveys, defect diagnosis, and planned preventative maintenance ensures the building is preserved while managing long-term costs.

How our experienced surveyors can help

TCL Chartered Surveyors have extensive experience surveying older residential and commercial buildings across the UK. We provide clear, practical advice grounded in how these properties actually perform.

Whether you are buying, managing, or planning works on an older property, an experienced surveyor can make all the difference in protecting its value and avoiding costly mistakes. Our team is ready to provide tailored surveys and guidance to help you look after your building properly.

The process for mitigating these risks is Contract Administration (CA), carried out by a RICS regulated Chartered Surveyor. The CA acts as your impartial administrator, ensuring the project is delivered to specification, on time, and against budget.

Mitigating Risk

Relying on informal agreements for large projects is inadequate given the financial and legal exposure. Professional CA establishes necessary control:

• Impartiality: The CA is independent of the contractor and holds no commercial interest. They provide a vital, neutral check on the builder’s performance and financial claims.
• Dispute Mitigation: By enforcing formal contract procedures, the CA standardises communication, significantly reducing the probability of costly disputes over quality or time.
• Compliance: The CA ensures works are managed to a professional standard, which is necessary for protecting the freeholder’s interest and meeting lease obligations.

Establishing the Contract Framework

The CA’s first critical task is selecting the most appropriate building contract. This choice dictates the rules and responsibilities for all parties.

We base this selection on the Joint Contracts Tribunal (JCT) suite of contracts, the UK standard. We assess core factors to ensure the correct JCT form is used:

This rigorous selection protects the association’s legal and procedural position from the start.

Financial Control and Certifying Payments

The highest financial risk is overpaying the contractor. The Contract Administrator’s role is to prevent this and safeguard the association’s funds.

The CA manages the financial aspects rigorously:

• Valuation: When the contractor claims payment, the CA conducts a detailed site inspection. Only after verifying the completed work’s quality and quantity is a formal Interim Certificate issued, authorising the payment.
• Retention Management: A set percentage of the contract value (retention) is held back. This sum is released only after the formal Defects Liability Period has ended, providing a commercial incentive for the contractor to return and rectify any remaining issues.
• Protection: The CA ensures that interim payments never exceed the proven value of the work executed and materials securely stored on site, ensuring financial integrity.

Managing the Unforeseen: Formal Instruction

Unforeseen issues are inevitable, especially in London’s older buildings. The CA must handle these deviations effectively and formally.

• Procedural Integrity: When a problem arises (e.g., latent defect), the CA formally issues a Variation or a Contractor’s Instruction.
• Documentation: This instruction legally amends the contract scope, details the required solution, and formalises any agreed adjustment to the timeline or cost. Every change is professionally documented, preventing future disputes.
• Mitigation: By applying formal contract procedures consistently, the CA ensures unforeseen issues are absorbed into the project structure efficiently, minimising the impact on the budget and the final quality.

Implementing professional Contract Administration is the most effective way for a residents association to discharge its duties regarding major works, ensuring successful project delivery and financial integrity.

Welcome to the exciting, and sometimes daunting, process of buying a home. We are TCL Surveyors, and as Chartered Surveyors with decades of experience and insight, our primary goal is to provide you with the professional insight necessary to make an informed, confident purchase.

In the UK, we often focus heavily on the financial and legal side of buying a property. However, it is the physical condition of the building itself that can lead to the most significant unexpected costs down the line. That is where a good surveyor proves to be worth their weight in gold.

Choosing Your Property: Initial Assessment

At this stage, your focus is naturally on location, layout, and décor. However, a surveyor’s mind is already assessing risk.

The Surveyor’s Value:

Early Warning Signs: As you view potential homes, be mindful of signs that might warrant a detailed survey later. These include visible cracking, patches of damp, pronounced sloping floors, or significant vegetation close to the building.

Construction Type: If you are viewing a property built using non-standard methods (e.g., concrete construction, thatched roofs, or very old timber frames), you should plan for a comprehensive survey from the outset, as these homes require specialist knowledge.

We provide peace of mind by confirming the structural integrity and overall condition of your chosen property.

Agreeing the Sale: The Conditional Offer

Once you have had an offer accepted, the next step is often the most overlooked: making the offer conditional on a satisfactory survey by a qualified surveyor.

Protecting Your Position: Never proceed too far with legal or financing costs before arranging a survey. An acceptable report is your leverage.

Selecting the Right Survey: A good surveyor will guide you on which of the three RICS Home Survey levels is appropriate:

Level 1 (Condition Report): Suitable for modern, standard-construction homes in good apparent repair. It is a concise overview.

Level 2 (Home Survey): Suitable for most standard homes, providing more detail on defects, repairs, and maintenance. This often includes a valuation.

Level 3 (Building Survey): Essential for older, larger, run-down, or non-standard properties. This is a comprehensive, deep inspection into the fabric of the building.

The surveyor ensures you commission a report that matches the complexity of the property.

Financing Your Property: The Mortgage Valuation

If you are using a mortgage, your lender will instruct their own surveyor to carry out a Mortgage Valuation. It is vital to understand what this report is – and what it is not.

For the Lender, Not You: The purpose of this valuation is solely to assure the lender that the property offers adequate security for the loan. It is a brief inspection that may identify significant issues, but it is not a detailed condition survey for the buyer.

Identifying Red Flags: If the mortgage valuation flags a major issue, the lender may demand a retention (withholding part of the loan) or ask for a specialist report, but this is the limit of its value to you. You must still commission your own, independent condition survey.

Arranging a Survey: Your Independent Report

This is the point where you instruct your chosen, independent Chartered Surveyor. This professional works exclusively for you.

Defect Diagnosis: The report will provide a clear, easy-to-read assessment of the property’s condition, highlighting urgent and significant defects like roofing failures, severe damp, or structural movement.

Repair Costs: A quality survey will not only point out the problem but also estimate the potential cost of rectifying it. This figure is crucial.

The Go/No-Go Decision: If the report uncovers significant issues (e.g., £20,000 worth of urgent roof repairs, excessive damp), you have three clear options:

i. Proceed, accepting the costs.

ii. Go back to the seller and negotiate a reduction in the agreed price.

iii. Withdraw from the sale without incurring further legal costs.

The surveyor gives you the commercial intelligence needed to secure a fair price.

Instructing Your Solicitor/Conveyancer: Integrating the Findings

Once the survey is complete, you should forward a copy to your solicitor immediately.

Legal Action: The solicitor will integrate the findings into their legal enquiries. For instance, if the survey finds damp, the solicitor may ask the seller for documentation proving a damp-proof course warranty is in place.

Specialist Referrals: If the surveyor recommends specialist investigation – such as a structural engineer for severe cracking, or a timber and damp expert – they can often help you source a reliable professional.

Exchange of Contracts: Full Commitment

This is the point of no return. You are now legally bound to buy the property – you need to have full confidence at this point! Crucially, the building insurance becomes your responsibility from this moment.

The Surveyor’s Value:

Insurance Confirmation: Your surveyor’s report will often include a Reinstatement Cost Assessment (RCA). This is the cost required to completely rebuild the property from scratch.

Correct Coverage: You must use the RCA figure, not the sale price, to determine your buildings insurance coverage. Under-insuring risks financial disaster should the property be destroyed.

Completion: A Confident Handover

On completion day, the legal ownership transfers to you. If you have followed this guide, you should take possession of the property with a full understanding of its condition. You are now free to post the pictures of keys on social media!

Planned Maintenance: Your survey report serves as a maintenance manual. It details which elements of the property will need attention in the short, medium, and long term, allowing you to budget for Planned Preventative Maintenance and avoid sudden, large expenses.

As a homeowner, your relationship with a surveyor does not end here. We remain the professional you call upon for advice on extensions, boundary disputes, or large-scale repairs. Trust in the surveyor’s expertise; it is the most prudent investment you will make in your new home.
