Local knowledge
What to know in Portsmouth
Portsmouth's older homes shape much of the picture: about 37% went up before 1919, and another 18% between 1919 and 1944. Older walls and footings can move as drains fail or roots spread, so a local specialist will often look at drainage repairs alongside subsidence repair. Terraced houses make up about 42% of the city's homes, and shared walls mean one building's movement can show up next door.

Stage by stage
From first report to finished repair
- 1
Describe the damage
Put the property address in the form and say in a few lines what you have noticed: cracks above a window or door, a step in the brickwork, a floor that has dropped toward one corner, or a frame that no longer closes properly. Say which way the cracks run, about how wide they are, and when they first appeared. Say whether the problem looks the same now or has got worse. A photo taken next to a coin or a pen gives the specialist a sense of scale. The quote is free of charge.

A phone call from a specialist
A subsidence specialist will ring you to go over what you have described and ask a few more questions. They will want to know the age of the house, the soil beneath it if you are aware of it, whether trees with large roots stand close by, and whether a drain or gutter has been losing water near the base of the house. Mention now if an insurer has already opened a claim.
- 3
Establishing the cause
From your account, the specialist judges whether a visit to the property will add anything. Where movement looks active, crack monitors can be fitted to take readings over several weeks. The pattern shows whether the building is still shifting, whether clay soil is drying and shrinking, or whether the structure has settled into a stable position. That evidence decides the repair method.

Questions that come up for properties in Portsmouth
Have a question? Ask us directly
My house is Victorian. Does that change what a survey looks at?
About 37% of homes in Portsmouth were built before 1919, and properties of that age often have shallow footings and original drains. Neither proves movement is happening, but both are worth flagging when you ask for an inspection. A specialist can then decide whether crack monitoring or resin injection is the right first step.
Do terraced houses and flats need different checks?
About 42% of Portsmouth homes are terraced and about 34% are flats. In a terraced house, a specialist will want to see the party walls and the drainage runs that serve more than one home. In a flat, the question is usually who is responsible for the structure below.
Do you cover the whole of Portsmouth?
Yes. Specialists cover all of Portsmouth and its surrounding areas, as well as neighbouring towns across the United Kingdom. Wherever you are locally, a specialist can help.
How quickly can you help?
Send us your details through the enquiry form and a specialist will come back to you promptly with initial advice for your Portsmouth property.
Will I need underpinning?
Often not. Many cases in this area are resolved by drainage repair, tree management or monitoring. A specialist only recommends underpinning where investigation shows it is genuinely required.
