Common Issues Identified During a Level 3 Survey

Structural Cracking
Cracks can indicate movement, settlement or structural issues. We assess their likely cause, severity and whether further investigation is recommended.

Damp & Condensation
We identify signs of damp, condensation and moisture ingress, explaining the cause and the potential impact on the property.

Roof Defects
From slipped tiles to ageing coverings, we inspect the roof for visible defects and recommend appropriate repairs where necessary.

Chimney Defects
Chimneys are exposed to the elements and can deteriorate over time. We check for cracking, loose masonry, damaged flashing and signs of instability.

Timber Decay
Rot, fungal decay and timber deterioration can compromise structural elements. We identify affected areas and explain the extent of any damage.

Gutter Problems
Blocked, damaged or leaking gutters can lead to damp and water damage. We inspect rainwater goods and highlight any maintenance issues.

Brickwork & Pointing
Weathering and failing mortar joints can allow water penetration and reduce structural integrity. We assess the condition of external masonry.

Electrical Concerns
While not an electrical test, we identify visible defects or outdated installations that may require further inspection by a qualified electrician.

Floor & Joist Issues
Uneven floors, movement or timber deterioration may indicate underlying problems. We assess visible signs and advise on any further investigation.

EXCELLENT Based on 220 reviews Posted on Google Daniel BlajTrustindex verifies that the original source of the review is Google. I recently used Surveying People for my Level 3 RICS survey as a first-time buyer, and I couldn’t be happier with the service I received—especially from Ross. The survey was incredibly detailed and was delivered promptly, giving me plenty of time to review everything. The report was easy to understand and contained very helpful information that highlighted important issues with the property. What really stood out was the follow-up phone call with Ross after I received the report. He took the time to go through my questions in a friendly, down-to-earth way, explaining everything clearly without making me feel rushed. As a first-time buyer, that human approach gave me the confidence I needed to make an informed decision. I highly recommend Surveying People, and especially Ross, to anyone looking for a thorough, professional, and genuinely helpful surveyor.Posted on Google Sorcha KehoeTrustindex verifies that the original source of the review is Google. Ross was excellent throughout the survey process. He was incredibly helpful, knowledgeable, and took the time to explain everything clearly. He also offered follow-up phone calls if we had any further questions after our initial discussion, which was greatly appreciated and gave us real confidence. Ross was encouraging when it came to negotiating a reduction in the purchase price based on the survey findings and provided practical, helpful advice. His support and willingness to go the extra mile made the whole process much less stressful. I would highly recommend Surveying People to anyone purchasing a property.Posted on Google Rawad AounTrustindex verifies that the original source of the review is Google. Professional, friendly, and prompt service. I would recommend and use them again. Five stars from me.Posted on Google Caroline WrightTrustindex verifies that the original source of the review is Google. Really pleased with the service provided. Full level 3 survey, followed by a long telephone call to discuss the contents.Posted on Google Koysor AbdulTrustindex verifies that the original source of the review is Google. Great overall experience with Surveying People. I had a Level 3 survey carried out on a property I'm purchasing. Ross, who carried out the survey, produced a very detailed report 5 days after the survey was carried out. The report highlighted things clearly and it was easy to digest. The post survey call with Ross was extremely helpful as I had a few questions which were answered.
“The survey was thorough and easy to understand. The surveyor was friendly, professional, and took time explaining everything clearly.”
