Building Defect Surveys
Targeted investigation of structural movement, cracks, dampness, water ingress and other building defects across Lancashire and the wider North West.
A building defect survey is a focused inspection of a particular problem rather than a general assessment of the whole property.
Williams Survey & Design investigates visible defects including cracking, dampness, water ingress, movement, defective masonry and failures affecting roofs, walls, floors and ceilings.
The inspection aims to establish the nature and extent of the problem, identify likely causes where reasonably possible, and provide proportionate recommendations for repair, monitoring or further specialist investigation.
We carry out defect surveys for homeowners, builders, contractors, developers and housebuilders where there is uncertainty or disagreement over causation, responsibility or the most appropriate remedial solution. Our experience includes undertaking inspections and investigations through one of our principal clients for major national housebuilders, as well as working on behalf of homeowners experiencing defects within their properties. We assess the available evidence, identify likely causation where reasonably possible, and provide clear, impartial recommendations to help all parties reach a practical resolution. Where required, we can also assist with developing an efficient and cost-effective rectification plan, coordinating remedial works and recommending suitably experienced contractors.
Problems We Investigate
Cracking and Movement
Cracking around openings, stepped masonry cracking, distorted walls, suspected settlement and signs of structural movement.
Dampness and Condensation
Visible dampness, mould growth, condensation, defective ventilation, penetrating moisture and suspected plumbing-related moisture.
Roofs and Water Ingress
Recurring leaks, defective roof coverings, flashing failures, rainwater goods and moisture entering roof spaces or internal finishes.
Masonry and External Walls
Bulging or leaning walls, deteriorated pointing, defective render, lintel problems, displaced masonry and weathering.
Floors, Ceilings and Internal Defects
Uneven or deflected floors, ceiling irregularities, cracking, failed finishes and concerns about supporting construction.
New-Build Defects
More complex or recurring defects requiring investigation beyond a basic snagging inspection.
What the Survey May Include
Depending on the defect and agreed scope, the investigation may include:
Visual inspection of accessible affected areas
Review of the defect pattern and surrounding construction
Moisture readings where appropriate
Level, alignment or dimensional checks
Photographic evidence
Consideration of likely causation
Practical repair recommendations
Advice regarding monitoring or further investigation
A written report setting out the principal findings
What the Survey Does Not Include
Unless specifically agreed, the inspection is visual and non-destructive. It does not include opening-up work, laboratory testing, drainage surveys, structural calculations or testing of electrical, gas, heating or plumbing installations.
Where specialist structural engineering, invasive investigation or laboratory analysis is required, this will be explained in the report.
Who We Work With
Defect Survey or Full Building Survey?
A defect survey is appropriate where the concern relates to a known or localised problem. A building survey is more suitable where an assessment of the property’s overall construction and condition is required.
Where several defects are present, or the condition of the wider property may be relevant, a Detailed Property Survey or Comprehensive Building Assessment may be more appropriate.
Request a Building Defect Survey
Send us the property address, a brief description of the problem and any photographs or supporting information available. We will review the enquiry before recommending an appropriate inspection scope and providing a written quotation.
