How conservatory subsidence repair works
Subsidence in a conservatory can show up as cracks running diagonally from the corners of glazing frames, a roof that no longer sits level, or gaps opening where the structure meets the main house wall. Those signs do not always mean major work is needed, but they do need a proper look. Each stage below follows the job from your first description of the symptoms right through to the completed repair and all paperwork handed over.
From the first message through to completed work, every conservatory subsidence repair job follows the same sequence of stages.
Describe what you have noticed
Submit the form with the property address and details of what you are seeing. Note where the cracks are, which direction they run and roughly how wide they appear. Say whether the conservatory floor has dropped, whether the roof line looks uneven, or whether the junction with the main house has opened up. Mention when you first noticed the problem and whether it has stayed the same or got worse. A photograph placed next to a coin or a ruler gives a useful sense of scale. The quote is free.
A specialist contacts you
A conservatory subsidence specialist will call to go through what you have described. They will ask about the age of the conservatory and the main house, the soil type beneath the footings if you know it, and whether any large trees grow close by. They will also ask whether a downpipe or drain has been leaking near the base. If an insurer has already opened a claim, say so at this point.
Assessing whether an in-person visit is required
Based on your account, the specialist will judge whether attending in person is the right next step. Where movement may still be ongoing, the specialist can place crack monitors to take readings across several weeks, establishing whether the structure is still shifting or has settled. That information shapes which repair method is appropriate.
Quote provided in writing at no cost
When the specialist has sufficient evidence, they put the probable cause in writing and set a price for the repair that addresses it. For a conservatory, that might cover underpinning the strip or pad foundation, resin injection to consolidate loose ground beneath the base, crack stitching, or removing a nearby tree whose roots are drawing moisture from clay soil.

The repair work
The specialist firm arranges access, confirms which parts of the conservatory and garden will be affected and agrees a schedule with you. Work covers only what the site evidence supports. A conservatory that has stopped moving gets no further work beyond what the site evidence justifies.
Foundation repairs and structural checks
Where the specialist carries out foundation repairs, they will also check the wall ties at the junction between the conservatory and the house. Corroded wall ties can cause horizontal cracking that is sometimes mistaken for subsidence. If tie failure is found alongside ground movement, both are addressed as part of the same programme of work.
Crack monitoring where needed
If the specialist sets up crack monitoring, readings are taken at agreed intervals and logged. The pattern of movement over time shows whether the ground is still shifting, whether seasonal clay shrinkage is the main driver, or whether the conservatory has settled into a stable position. That record forms part of the final documentation.
Paperwork at the end
At the end of the job, the specialist puts together a written report detailing what the investigation found, what was done and the state of the structure on completion. Any certificate issued should be filed with the rest of your property documents. Insurers, mortgage lenders and solicitors acting on behalf of buyers routinely request records of previous ground movement, and a conservatory with a clear repair history presents fewer complications than one without any documentation.
