Chartered structural engineers, detailed reports
Chatham homes sit on ground that can change from one street to the next, with chalk in the geology and clay also likely to appear in the local profile. That mix can matter when a wall starts to crack or a floor begins to dip, especially in parts of Medway that are also susceptible to flooding. Our structural engineers regularly inspect properties across Chatham, including the High Street Heritage between Rochester and Chatham and the area around the Historic Dockyard. Older listed buildings, conservation areas and past alterations often need a more measured look than a standard condition check.
We assess whether the issue is surface movement, a load path problem, or something deeper in the foundations. Signs such as stepped cracking, doors that have started to bind, sloping floors or a gap opening between wall and ceiling can all point to structural movement. A structural survey gives clear findings, with practical next steps and, where needed, calculations for remedial works. It is useful for buyers, sellers and homeowners who want a proper diagnosis before the damage spreads.
A structural survey looks at the parts of a building that carry load and keep the structure stable. Our structural engineers examine foundations, load-bearing walls, lintels, roof members, floor joists and visible signs of movement, then connect the symptoms back to the most likely cause. In Chatham, that matters in older properties near the Historic Dockyard, where repeated repairs, past alterations and mixed-age construction can hide the real issue. We do not stop at the crack line, because the crack is only the clue.
The survey also checks for subsidence, heave, lateral movement and damage linked to damp where moisture has affected structural fabric. Around the High Street Heritage between Rochester and Chatham, listed buildings and conservation areas often carry a longer repair history, so we compare current distortion with the way the building should sit. Where access allows, we measure levels, record crack patterns and note any distortion to openings, ceilings and roof lines. That evidence helps separate cosmetic damage from movement that needs attention.
Chatham's ground conditions make a careful appraisal worthwhile. The geology of Kent here includes chalk, and the presence of clay means shrink-swell movement can become part of the picture when weather swings are sharp. In practical terms, that can affect shallow footings, older brickwork and any property that has seen uneven moisture levels over time. Our engineers pay close attention to those patterns in Medway because a small change in ground movement can turn into a much larger repair if it is left unchecked.
Medway's flood-prone areas add another layer of risk. Periodic inundation can soften ground, affect external walls and create problems around drainage runs, retaining edges and lower floors. Chatham also has several listed buildings and conservation areas, while the Historic Dockyard includes over 100 buildings and structures, 47 of them Scheduled Ancient Monuments. Places such as Hulkes Lane Brewery Buildings, The Cottage on Cooks Wharf and the Jewish burial ground at Chatham Memorial Synagogue show how much older fabric sits alongside later additions, and that mix demands a careful structural eye.
The clearest warning signs tend to appear slowly. Diagonal cracks through masonry, stepped cracking along mortar joints and horizontal cracks near a wall that is carrying load all deserve attention, especially if they are getting wider. Sticking windows and doors can point to distortion in the frame, while sloping floors and bulging walls often suggest that movement is more than cosmetic. In conservation streets around the High Street Heritage, patched repairs can hide a longer history of movement, so the pattern matters as much as the size of the crack.
Structural movement usually shows a cluster of symptoms rather than one isolated mark. A gap between the wall and ceiling, fresh cracking after an extension, or a chimney breast that seems to lean all give us reasons to investigate further. Around the Historic Dockyard and nearby older homes, changes after heavy rain can also point towards softening ground or drainage stress. If a wall has been removed, a roof has been altered, or an opening has been widened, we check the load path and the support above it before anyone assumes the work is harmless.
We start with the symptoms you have seen, the property age, any recent works and the location in Chatham. If the building sits near the High Street Heritage or the Historic Dockyard, that context helps us plan the right level of inspection.
A site visit usually takes 2-3 hours, depending on severity and access. We inspect visible structure, take measurements, assess crack patterns and check for distortion to openings, floors and roof lines.
Where movement is suspected, we map cracks, look for level changes and review likely causes such as clay shrink-swell, drainage issues or loading problems. We may also assess whether flood exposure in Medway has contributed to the fault.
Our structural engineers analyse the evidence, check load paths and prepare any necessary calculations. If remedial work needs a designed solution, we can set out specifications that builders can follow.
Your report usually arrives in 5-10 working days. It explains the defect, the likely cause, the risk level and the next steps in clear language.
We talk through the findings and answer any questions about repairs, monitoring or the next survey stage. If the issue needs monitoring over 12 months, we explain what to track and why that timeline matters for a subsidence claim.
Hairline cracks are not all equal. Some come from drying plaster, thermal expansion or normal seasonal movement, while others reveal active structural change in the frame or foundation. The clue is the pattern, the width and whether the crack is changing over time. In Chatham, where chalk sits alongside clay in the local geology, we look closely at how weather, drainage and soil moisture may be affecting the building rather than treating every crack as a failure.
Moderate or severe cracking needs a more disciplined approach. A stepped crack through brickwork, a horizontal crack near a wall plate or a crack that widens after wet weather can suggest progressive movement rather than one-off settlement. Monitoring is often the right first step if the building is stable and there is no immediate structural danger, but subsidence claims usually require observation over 12 months before remediation is agreed. That timeline helps separate seasonal behaviour from a genuine and ongoing problem.
Foundations in Chatham need to be judged against the ground below them, not just the age of the house above. Chalk can give firm support, but clay pockets can shrink and swell, and that movement can disturb shallow footings or older masonry. In Medway, flood exposure can also affect subsoil conditions, so our engineers look at drainage, nearby hardstanding and signs of historic water stress before forming a view. The result is a diagnosis that reflects the site, not just the crack.
Subsidence assessments often involve more than a visual check. We look for tell-tale patterns in door frames, floor levels and brick joints, then compare those signs with weather history, vegetation near the property and any known alterations. Around the Historic Dockyard and the conservation areas linked to the High Street Heritage, older repairs can mask movement for years before fresh symptoms appear. If root action, clay shrinkage or drainage failure looks likely, we say so plainly and set out the next step, which may include monitoring, repair design or insurance evidence.
A structural survey is sensible when cracks are widening, floors are sloping, doors or windows are sticking, or a wall has been removed without clear support design. It is also sensible before buying an older or altered property in Chatham, especially where the building sits near conservation areas or the Historic Dockyard. If the problem looks linked to movement rather than decoration, a structural engineer can check the cause properly.
A structural survey is led by chartered structural engineers, and it focuses on load paths, foundations, movement and repair design. A building survey is broader and is usually carried out by a RICS surveyor, with more emphasis on general condition and maintenance. If the issue is cracking, subsidence or a suspected failure in the structure, the engineering route gives the deeper analysis.
Our structural survey prices start from £500, and the local average in Chatham is around £915, with a typical range of £633 to £1383. The final cost depends on the size of the property, the level of movement, and how difficult it is to reach the affected areas. Older homes and properties with complex layouts around the High Street Heritage can take longer to assess.
A site visit usually takes 2-3 hours, though a difficult case can run longer if access is tight or the issue affects several parts of the building. The report is then prepared after the inspection, and delivery usually takes 5-10 working days. If the survey reveals active movement, we may recommend monitoring or a follow-up review.
Yes. Our structural engineers assess subsidence by looking at crack pattern, level changes, floor distortion, moisture effects and anything nearby that could be influencing the ground. In Chatham, that can include clay shrink-swell behaviour, flood exposure in Medway and the effect of trees or drains on local soils. If the evidence suggests subsidence, we can explain whether monitoring, repair design or insurer engagement comes next.
Sometimes, but the cover depends on the cause of the damage and the wording of the policy. Sudden damage is often treated differently from gradual movement, and many insurers want evidence before they accept a claim. If your home in Chatham is showing new cracks or movement, a structural report gives the technical record that insurers usually ask for.
Yes, if the work affects a load-bearing wall, chimney breast or roof support, a structural check is sensible. We review whether the new opening has the right support, whether the load path has been changed and whether any movement has started after the works. That is especially useful in older homes near the Historic Dockyard, where past alterations can hide a weak point.
The report explains what we found, why the defect is happening and how serious it appears to be. It can also include calculations and specifications for remedial works if the structure needs repair design. That gives you a clear basis for builder quotes, negotiations or further monitoring.

Structural survey pricing in Chatham starts from £500, with the local average around £915 and a typical range of £633 to £1383. For lighter inspection work, a RICS condition report averages £517 and a Homebuyer report averages £557, while a more detailed building survey sits at the higher end because it takes longer and needs deeper analysis. Nationally, a full structural survey is often quoted at around £800, so Chatham's figures sit a little above that level. The difference usually reflects property age, access and the amount of investigation needed.
Several factors push the price up or down. A large property near the High Street Heritage, a building with previous alterations, or a home showing active movement will need more time on site and more office analysis afterwards. Our report will normally set out the defect, the likely cause, the risk level, and any repair recommendations, with calculations and specifications where the problem needs a designed solution. If the issue is linked to subsidence or flood exposure in Medway, we may also recommend monitoring before any remediation goes ahead.
