The Importance of Building Inspections

When it comes to purchasing a property, the excitement of finding your dream home can often overshadow the critical need for a thorough building inspection. At Flettons Surveyors, we understand that a property is more than just bricks and mortar; it’s an investment, a sanctuary, and a significant financial commitment. Today, we take you through a detailed inspection of a 1930s semi-detached house on Northumberland Avenue, DA16, to highlight the importance of identifying potential issues before making a purchase.

The Property: A 1930s Semi-Detached House

Located in the charming neighbourhood of Northumberland Avenue, DA16, this 1930s semi-detached house recently underwent refurbishment. However, prior to this, it had been heavily extended, albeit to a poor standard. Our inspection aimed to uncover any hidden threats that could affect the property’s value, safety, and longevity.

Front Bay Cracking Due to Differential Movement

Understanding Differential Movement

Differential movement occurs when different parts of a building settle at different rates. This can be due to various factors such as soil conditions, foundation types, and construction methods. In the case of the Northumberland Avenue property, we observed significant cracking in the front bay area.

Identifying the Signs

During our inspection, we noted the following signs of differential movement:
– Cracks in the Brickwork: Visible cracks running vertically and diagonally in the front bay area.
– Uneven Floors: Slight unevenness in the flooring near the front bay.
– Misaligned Windows and Doors: Difficulty in opening and closing windows and doors in the affected area.

Potential Risks and Solutions

If left unaddressed, differential movement can lead to structural instability. To mitigate this, we recommend:
– Engaging a Structural Engineer: A professional assessment to determine the extent of the movement and necessary remedial actions.
– Foundation Reinforcement: Strengthening the foundation to prevent further movement.
– Regular Monitoring: Keeping an eye on any new cracks or changes in the existing ones.

Warped Window Units

Causes of Warped Windows

Warped window units are often a result of poor installation, substandard materials, or exposure to extreme weather conditions. In this property, we found several windows that were not closing properly due to warping.

Inspection Findings

Our inspection revealed:
– Gaps Between the Frame and Sash: Allowing drafts and moisture to enter.
– Difficulty in Operation: Windows that were hard to open or close.
– Visible Warping: Noticeable bending or twisting of the window frames.

Addressing the Issue

To resolve the problem of warped windows, we suggest:
– Replacing Affected Windows: Using high-quality, weather-resistant materials.
– Ensuring Proper Installation: Hiring experienced professionals to install the new windows.
– Regular Maintenance: Periodically checking and maintaining the windows to prevent future warping.

Blown Glazing Units

What Are Blown Glazing Units?

Blown glazing units occur when the seal between the panes of double-glazed windows fails, allowing moisture to enter and causing condensation between the panes. This not only affects the window’s appearance but also its insulating properties.

Inspection Observations

In the Northumberland Avenue property, we identified several blown glazing units with:
– Condensation Between Panes: Foggy or misty appearance inside the glass.
– Reduced Insulation: Noticeable drafts and temperature variations near the windows.
– Decreased Aesthetic Appeal: Cloudy windows detracting from the property’s overall look.

Remedial Actions

To address blown glazing units, we recommend:
– Replacing the Affected Units: Installing new double-glazed units with improved seals.
– Regular Inspections: Checking the seals periodically to catch any issues early.
– Quality Assurance: Ensuring that the replacement units are of high quality and installed correctly.

Incompatible Render Mixes on External Walls

Understanding Render Mix Compatibility

Render is a protective coating applied to external walls. Using incompatible render mixes can lead to various issues, including cracking, dampness, and poor adhesion. In this property, we found that different sections of the external walls had been rendered with incompatible mixes.

Inspection Findings

Our inspection revealed:
– Cracking and Flaking: Visible cracks and areas where the render was peeling off.
– Damp Patches: Signs of moisture penetration in certain areas.
– Inconsistent Appearance: Different textures and colours on the external walls.

Solutions and Recommendations

To rectify the issue of incompatible render mixes, we suggest:
– Removing the Existing Render: Stripping off the incompatible render.
– Applying a Uniform Render Mix: Using a compatible and high-quality render mix for the entire property.
– Professional Application: Ensuring that the render is applied by experienced professionals to achieve a consistent finish.

Mould on Inner Walls

Causes of Mould Growth

Mould growth inside a property is often a result of excess moisture, poor ventilation, and inadequate insulation. In the Northumberland Avenue house, we discovered mould on several inner walls, particularly in areas with poor ventilation.

Inspection Observations

During our inspection, we noted:
– Visible Mould Patches: Black or green mould on walls and ceilings.
– Musty Odour: A damp, musty smell in affected areas.
– Health Concerns: Potential health risks for occupants, including respiratory issues and allergies.

Addressing Mould Issues

To tackle mould growth, we recommend:
– Improving Ventilation: Installing extractor fans and ensuring adequate airflow in all rooms.
– Addressing Moisture Sources: Identifying and fixing any leaks or sources of moisture.
– Using Anti-Mould Paint: Applying paint with mould-resistant properties to affected areas.
– Regular Cleaning: Keeping the property clean and dry to prevent mould recurrence.

Nail Sickness on the Roof Covering

What Is Nail Sickness?

Nail sickness occurs when the nails used to secure roof tiles or slates corrode and lose their holding power. This can lead to loose or missing tiles, compromising the roof’s integrity. In this property, we found several instances of nail sickness on the roof covering.

Inspection Findings

Our inspection revealed:
– Loose or Missing Tiles: Tiles that were not securely fastened or had fallen off.
– Corroded Nails: Visible signs of rust and corrosion on the nails.
– Potential Leaks: Areas where water could penetrate the roof due to missing tiles.

Remedial Actions

To address nail sickness, we suggest:
– Replacing Corroded Nails: Using stainless steel or galvanised nails to prevent future corrosion.
– Securing Loose Tiles: Ensuring all tiles are properly fastened.
– Regular Roof Inspections: Periodically checking the roof for any signs of nail sickness or other issues.

The Value of a Thorough Building Inspection
