What Happens on Survey Day? A Step-by-Step Guide to Your Property Inspection

For most buyers, a property survey is something that just "happens" during the buying process — you instruct a surveyor, they go to the property, you receive a report. But understanding exactly what happens on survey day can help you get more from the process, ask better questions, and make sense of your report when it arrives.

Here's a full, transparent account of what our RICS surveyors actually do during a property inspection.

Before Survey Day

Good preparation makes for a better survey. Before attending the property, our surveyor will:

• Review the property details (age, construction type, tenure, asking price)
• Research planning history and any relevant local factors (known subsidence zones, tree preservation orders, flood risk)
• Review any documentation provided (title deeds, planning consents, previous surveys if available)
• Confirm access arrangements with the estate agent or vendor

Arrival at the Property

Our surveyors arrive at the agreed time, introduced to the vendor or occupier if present, and carry out a brief walk-through to get an overall impression of the property before beginning the systematic inspection. First impressions are important — they help identify areas to investigate more closely.

Exterior Inspection

We begin with a full inspection of the exterior, working systematically around the building:

• Roof: Condition of tiles/slates, ridge tiles, verge and eaves details, chimney stacks and flashings, gutters and downpipes — inspected from ground level and, where safe, from a ladder
• Walls: Condition of brickwork, pointing, render or cladding; any cracking, staining, bowing or leaning; DPC level relative to external ground level
• Windows and doors: Frames, glazing units, opening and closing operation, security
• Flat roofs: All accessible flat roof areas inspected for condition, falls, upstands and drainage
• Outbuildings and boundary structures: Condition of garages, sheds, walls and fences where included in the purchase
• Drainage: External inspection of manhole covers, gullies and visible drainage runs

Interior Inspection

The interior inspection is the most time-consuming part. We inspect every room, working from the top floor down:

• Ceilings: Evidence of water ingress (staining, cracking, bulging), structural defects
• Walls: Cracking (pattern, width, location), damp (using a calibrated damp meter), evidence of previous repairs
• Floors: Levelness, condition of coverings, any bouncing or movement indicating subfloor issues
• Windows and doors: Operation, draught-proofing, condensation in glazing units
• Kitchens and bathrooms: Sanitary fittings, tiling, ventilation, drainage
• Services: Consumer unit (fuse box) inspection, visible pipework, boiler age and condition, visible radiators

For Level 3 surveys, we also inspect under floor coverings where liftable, behind panels where accessible, and carry out a more detailed assessment of every identified defect.

Roof Void Access

On Level 3 surveys (and where accessible on Level 2), we access the roof void through the loft hatch. This is one of the most important parts of the inspection — the roof structure and the conditions inside the roof void can reveal a great deal about the property's history and condition:

• Structural condition of rafters, joists and ridge beam
• Evidence of water ingress (staining, timber decay, daylight visible through the covering)
• Insulation type, depth and coverage
• Cold water storage tanks (condition, insulation, overflow provision)
• Any signs of rodent or pest activity

Equipment We Use

• Calibrated damp meter: Measures moisture content in walls, floors and ceilings
• Binoculars: For inspection of high-level roof elements from ground level
• Spirit level: For checking floors, walls and lintels for movement
• Borescope camera: Where cavity inspection is warranted (cavity wall tie assessment)
• Ladder: For roof-level and high-level access where safe and practical
• Torch: For inspection of roof voids, understairs areas and service runs
• Camera: Detailed photographs of every significant finding

How Long Does a Survey Take?

This depends on the survey level and the size and complexity of the property:

• Level 1 Condition Report: 1–2 hours on site
• Level 2 HomeBuyer Report: 2–3 hours on site
• Level 3 Building Survey: 3–5 hours on site (longer for larger or more complex properties)

A surveyor who spends 45 minutes on a Level 3 survey of a Victorian terrace has not carried out a thorough inspection. Always ask how long the inspection will take as part of your research when choosing a surveyor.

After the Inspection: The Report

After leaving the property, our surveyor will write up their findings in a detailed report. This typically takes 1–3 working days. The report includes:

• A clear summary of key findings and any urgent issues
• Section-by-section assessment of all elements inspected
• Photographs of significant findings
• Condition ratings (for HomeBuyer Reports: Category 1, 2 or 3)
• Guidance on further investigations where needed
• Estimated repair costs (Level 3 surveys)
• Legal issues to raise with your solicitor

The Debrief Call

At Croydon Surveyors, we call every client personally after their report is delivered. This is something we consider non-negotiable. A written report can't answer your follow-up questions or help you decide how to proceed — a conversation with your surveyor can.

In our debrief calls, we'll walk you through the key findings, explain what they mean in plain English, advise on priorities, and help you think through how to use the report in your negotiations.

Should You Be There on Survey Day?

You're welcome to be present during the inspection, but it's not necessary or expected. Some clients prefer to attend at the end of the inspection to ask questions in person. Vendors are usually asked to leave the property empty to allow unrestricted access.

If you do attend, please avoid following the surveyor around during the inspection — this can disrupt the systematic process and may cause items to be missed.
