Via either a desk or site assessment we assess visible signs of movement and recommend suitable remediation solutions designed to improve ground conditions, strengthen weak ground and support affected foundations.

Frequently Asked Questions

Do I need a subsidence survey before contacting Mainmark?

No. Many customers contact us before obtaining a survey. If a formal diagnosis or report is required, we may recommend speaking with a Chartered Surveyor or Structural Engineer.

I already have a survey or engineer's report. Can Mainmark provide a quotation?

Yes. We regularly provide quotations where investigations have already been completed and remedial works have been recommended.

Can Mainmark diagnose subsidence?

We assess signs of movement and recommend remediation solutions. Formal diagnosis and structural reporting are typically provided by Chartered Surveyors or Structural Engineers.

Can Mainmark help with insurance claims?

If a claim is still under investigation, insurers will usually appoint their own consultants and contractors. If you are funding works privately or have received an insurance settlement, we may be able to assist.

Will every property with cracks require remedial works?

No. Some properties require only monitoring or further investigation. The most appropriate course of action depends on the cause and extent of the movement.

What happens if remedial works are recommended?

If remedial works are considered appropriate, we will explain the available options, discuss the proposed approach and provide a no-obligation quotation.

Solutions may include ground improvement, foundation remediation or other specialist techniques depending on site conditions and the nature of the movement observed.

Is the Property Assessment Free ?

Yes the property assessment is free if you are the homeowner.

Do I need to own the property?

We normally work directly with property owners or those authorised to act on their behalf.

If you are a tenant, we may need the property owner's permission before progressing any assessment or proposed works.

What signs of subsidence or settlement should I look for?

Common indicators can include:

  • Stepped cracks in brickwork

  • Cracks around doors and windows

  • Internal wall cracking

  • Doors or windows sticking

  • Uneven or sloping floors

  • Gaps appearing around walls, floors or openings

  • Visible movement between extensions and the main property

    These symptoms do not always indicate subsidence and can occur for other reasons, so professional assessment may be required.

Are cracks always caused by subsidence?

No. Cracking can occur for many reasons, including seasonal movement, thermal expansion, shrinkage, settlement, construction methods and changes in moisture levels. A Chartered Surveyor or Structural Engineer can provide an independent diagnosis where required.

What information may be helpful before an assessment?

  • Any previous survey or engineering reports

  • Photographs of cracks or affected areas

  • Approximate age of the property

  • Information about foundations, if known

  • Nearby trees or recent tree removal

  • Any history of drainage issues

  • Details of previous structural repairs

Don't worry if you don't have all of this information. We can advise on what may be relevant.
