Common Structural Problems in Cardiff Properties
There is always a risk of a UK property developing structural problems, and Cardiff is no exception. We’ve observed several structural repair concerns among properties in Cardiff, including:
- bowing, cracking, or collapsed masonry
- lintel damage and failure
- wall-tie corrosion
- damaged or decayed timber, either from fungal decay or woodworm
- rotten joist ends, especially those in direct contact with masonry
- structural movement and subsidence
- concrete deterioration
- moisture-related damage from rising or penetrating damp
Structural Repairs for Cardiff's Older Buildings
Cardiff, like many areas of the UK, has a high proportion of heritage buildings. From Victorian and Edwardian homes to period townhouses and listed buildings, Cardiff’s buildings have an established history with a variety of building styles and techniques.
Understanding the way conservation area properties were originally built is the key to restoring them successfully. Buildings in conservation areas require repairs in-keeping with building’s original materials, and ensure the preservation of such properties.
Cracking and Structural Movement
Structural cracking can result from wall tie failure, material deterioration or movement within the building fabric. Left unresolved, these issues may worsen over time.
In properties with corroded or failed wall ties, cavity wall tie replacement may be required. This restores structural integrity and prevents further cracking or bowing of external walls.
Our surveyors confirm whether replacement is necessary and specify the appropriate system for your property.
Concrete Repairs in Cardiff
Concrete elements can weaken due to age, corrosion or environmental exposure. Our concrete repairs in Cardiff are designed to restore structural strength while protecting against future deterioration.
Repairs are carried out using proven methods suited to the condition of the structure. Every project begins with a detailed structural assessment. We explain the findings clearly, outline recommended repairs and provide a straightforward quotation.
When Damp Becomes a Structural Problem
Water ingress occurs when moisture finds its way into the structure of a building, either by rising through small capillaries in masonry, or through a small defect or leak in a building’s walls or roof.
Damp can spread rapidly into adjacent floor or roof timbers, creating the ideal conditions for timber decay to develop. Once established, fungal decay can spread quickly, sucking the strength out of the timber as it spreads to new areas of a property. If left untreated for long enough, this can lead to timber warping, and potential structural collapse, putting any inhabitants at risk of serious injury.
Whilst we often have same-week availability in Cardiff, it can be dependant on demand. Call 02920 290 558 to speak to us and find the earliest survey appointment that works for you.
Repair costs depend on the cause and extent of the problem in the property. You will receive a written report following your survey that will include a clear quote for any recommended remedial works.
Of course – no matter if you are in the dead centre of Cardiff, or outside the city entirely, our team are going to be able to help. We cover the entire South Wales area, so if you need a survey, just get in touch!
