Surveyor Missed Damp During House Survey
Key Takeaways:
-
Significance of Undetected Rising Damp: If rising damp goes unnoticed in a property survey, it poses a serious concern as it has the potential to cause structural damage and compromise the overall integrity of the building.
-
Factors Contributing to Non-Detection: Various factors may contribute to rising damp not being identified in a survey.
-
Post-Survey Steps for Rising Damp Concerns: In the event of discovering rising damp after the survey, it is advisable to consult with a damp specialist or qualified structural engineer.
So, you saw some wet spots in the old house – not very big, only tiny little ones, which had the potential to scare you and think of them as damp patches.
Well, guess what? – You discussed it with your family members, friends, and neighbourhood and what came up is that everybody said there a rising damp issue in the ground floor of your house. You need to get it fixed as soon as possible unless your house will get destroyed.
Therefore, you searched for a damp survey. You called the survey professionals in, and they surveyed your house, but eventually, the final result that came out was like an unexpected surprise.
The damp survey says that there’s no rising damp in your house. Now what? Should you be happy or feel upset about your lost money on a house survey that missed damp? Well, let’s see what it means when rising damp is not picked up on a damp survey.

What if Rising Damp Was Not Picked Up On Survey?
If your surveyor missed rising damp, it becomes a major worry since it has the potential to cause structural damage and jeopardise the overall integrity of the structure. Nonetheless, the lack of identification throughout the survey might be attributed to a variety of complex circumstances, such as:
Limited Access
Some areas of a property may be difficult to access during a survey. If particular walls or spaces were not thoroughly examined, rising damp may have gone unnoticed.
Recent Occurrence
Rising damp may not have been present at the time of the survey or may have developed after the survey was conducted. Conditions contributing to rising ground damp, such as changes in groundwater levels or drainage issues, can evolve over time.

Hidden Symptoms
Rising floor damp can sometimes be concealed behind plaster or wall coverings. If the visible symptoms were not apparent during the survey, it might explain why your surveyor missed the damp issue.
Inadequate Surveyor Knowledge
Not all surveyors may have the same level of expertise in identifying rising damp. Some may focus more on structural issues or other aspects of the property.
If you discover rising damp after the survey, here are some steps to consider:
Consult with a Damp Specialist
If you suspect rising damp, consult with a damp proofing specialist or a qualified structural engineer. They can conduct a more detailed assessment to confirm the presence of rising damp and identify the underlying causes.
Request a Review of the Survey
If rising damp was missed during the initial survey, contact the surveyor to discuss the findings and request a review. Provide them with the new information and ask if they can reassess the property.

Document the Issue
Document the rising damp issue with photographs and detailed notes. If your house survey missed damp, this documentation can be valuable when communicating with the surveyor, seeking professional advice, or discussing the matter with relevant parties.
Obtain Multiple Opinions
It’s often beneficial to obtain opinions from more than one professional. Seek quotes and assessments from different damp specialists or structural engineers to ensure a comprehensive understanding of the issue.

Check for Warranty or Insurance
Review any warranties or insurance policies that may cover the property. Some policies may provide coverage for specific structural issues, and you may be able to make a claim for necessary repairs.
Address the Issue Promptly
Rising damp can lead to further damage if not addressed promptly. Once identified, take steps to remediate the issue by implementing the appropriate treatments and repairs.
I Think the House Has Damp, But the Survey Says Otherwise
Begin communication with the surveyor who missed damp on the initial survey, ensuring that the data you have carefully gathered is conveyed while expressing your concerns. Request a thorough explanation of the survey findings and explicitly ask about any potential limits in the evaluation procedure. Further:
Request a Reassessment
Request a reassessment or a follow-up inspection from the original surveyor or a different professional. It can help verify the accuracy of the initial findings and provide additional insights into the condition of the property.

Seek Legal Advice
If the damp issue is significant and the surveyor’s report is misleading or inaccurate, you may want to seek legal advice. Consult with a solicitor to understand your options and whether there are grounds for a complaint or legal action.
Obtain Multiple Opinions
Consider obtaining opinions from more than one professional. Seek quotes and assessments from different experts to ensure a comprehensive understanding of the issue.

Take Prompt Action
If the presence of damp is confirmed, take prompt action to address the issue. Delaying repairs can lead to further damage and potentially higher repair costs.
What if the Damp Surveyor Hasn’t Looked for Damp Thoroughly?
If you have concerns about the damp surveyor’s lack of thoroughness in checking any damp issues in your house, it is critical that you address the problem as soon as possible. Poor-quality surveys have a tendency to overlook the hidden problems that might worsen over time. Herein, we provide a set of actions for your consideration:
Note Down Your Concerns
Note down your specific concerns about the survey. Note any visible signs of damp, such as discoloured patches on walls, peeling paint, or musty odours. Take photographs as evidence.

Review the Survey Report
Carefully review the survey report to understand what areas were assessed and what methodology was used. Check if there were any limitations mentioned in the report.
Contact the Surveyor
Reach out to the surveyor who missed the damp to discuss your concerns. Provide them with the evidence you’ve documented and ask for clarification on the areas that were or were not thoroughly examined. Inquire about the reasons for any limitations in the survey.

Request a Reassessment
If your house survey missed damp and you are dissatisfied, request a reassessment or a follow-up inspection. Clearly communicate the specific areas or issues you believe were not adequately examined. Make sure that the surveyor addresses your concerns in the reassessment.
Seek a Second Opinion
Consider obtaining a second opinion from another damp specialist or a qualified structural engineer. They can provide an independent assessment of the property and offer insights into the presence of damp issues.
Can You Get Compensation for Damp Surveyor’s Mistake?
A surveyor is required to exercise reasonable care and competence, and if they overlook a flaw that a qualified surveyor would have discovered, they can sue for professional negligence. The amount of protection varies based on the type of survey.

Claiming reimbursement for a fundamental value survey (conducted for the lender) is complex and limited to severe faults such as an unsupported chimney breast. You have a good case for compensation if you have a homebuyer’s report or a thorough structural survey. Because these surveys give adequate data, it is likely that the surveyor is to blame for failing to uncover hazards such as moist walls.

If you prove negligence, your reimbursement is restricted to the difference between the actual purchase price and what you would have paid if you were aware of the faults. It might be less expensive than the full cost and expense of repairs.
What is Included in a Damp Survey?
If you see any indicators of moisture in your home, it is recommended that you get a thorough damp survey. This rigorous inspection is overseen by an experienced damp specialist, whose primary role includes a complete evaluation of the caused damage, as well as the giving of a precise estimate that provides for repair costs and continuing maintenance needs.
The damp survey’s complexities include both external and internal examinations, ensuring that the damp specialist is well-equipped to provide you with a very exact and thorough damp report indeed.

Inspecting the External Area of the House
Your Damp Specialist will begin a thorough external evaluation of your house, carefully evaluating its outside features. Prior to this, the property survey is thoroughly reviewed, allowing them to incorporate any essential information about the outside and offering a strategic roadmap for their inspection.
The thorough exterior inspection includes:
-
- Extensive analysis of the pebble dash and rendering
-
- Investigation of the bricks thoroughly for any evidence of deterioration or fractures.
-
- Examination of damp proof course to ensure its existence and effectiveness.
-
- Detailed examination of doors and windows, with emphasis on any sealant damage.
-
- Comprehensive inspection of guttering and downpipes for any existing problems.
-
- A thorough assessment of the property point.
-
- Identification of probable roof concerns, including a look for damaged tiles.
Even if the preliminary structural investigation revealed no exterior issues, this comprehensive external check is required. It acts as a preventative approach, addressing and minimising possible concerns that may arise in the future.
Inspecting the Internal Area of the House
Following the external evaluation, professionals undertake an internal audit. Most specialists analyse the initial property study prior to their arrival, identifying key issues. Furthermore, findings from their external inspection help to their internal evaluation.
This full inside inspection includes thermal imaging, damp and moisture meter readings, and detailed visual assessments. The Damp Specialist carefully notes thorough observations and photographs, allowing for the creation of an accurate and complete report.
What if Damp is Revealed in the Survey?
If your survey reveals damp in your home, respond quickly and carefully. Determine the type of damp (penetrating, rising, or condensation) first, as each demands a different approach.
For a thorough inspection and tailored solutions, consult a skilled damp specialist. Get a detailed report from them that includes their findings, proposed remedies, and anticipated expenses.
Priority repairs should be made to address the severity of the damp problem, especially if it causes structural damage or health issues. Install a damp-proof course, improve ventilation, repair leaks, or resolve structural difficulties to address the underlying causes.
Obtain service quotes from damp removal professionals to ensure competitive pricing. Before making a decision, consider the recommended solutions, materials, and professional reputations.
