Mould Remediation Treatment & Investigation — Romsey Road, Winchester

Project Overview

British Builders attended a residential property on Romsey Road in Winchester to complete mould remediation treatment and investigate the likely cause of mould growth inside the home.

The issue affected wall corners, lower wall areas, skirting-level sections, window junctions and isolated ceiling/wall surfaces. Our team inspected the affected rooms, checked window seals, frame junctions and ventilation points, then protected the work areas before treatment began.

Visible mould was cleaned and treated using professional-grade fungicidal wash. Treated surfaces were then stabilised, primed and locally redecorated with anti-mould paint, helping restore a cleaner finish and identify whether further ventilation or maintenance may be required.

Scope of Work

• Inspection of mould-affected rooms and surrounding surfaces
• Assessment of mould staining, damp marks and affected wall areas
• Review of window seals, frames, junctions and ventilation points
• Assessment of possible condensation, cold bridging or minor water ingress
• Protection of flooring, carpets and nearby surfaces
• Cleaning and treatment of visible mould with fungicidal wash
• Application of mould-resistant primer and anti-mould paint
• Final inspection, clean-down and removal of waste materials

Challenges & Solutions

• Multiple affected areas — Rooms were inspected widely, not only around the most visible mould spots.
• Unclear moisture source — Walls, skirting areas, windows and ventilation points were reviewed to identify likely causes.
• Condensation risk — Mould patterning was assessed to check for condensation, cold bridging or minor ingress.
• Junction staining — Window boards, frames and wall edges were carefully cleaned and treated.
• Decorative finish — Treated areas were primed and redecorated with anti-mould paint.

Final Outcome

The mould remediation treatment and investigation works were completed successfully.

Affected surfaces were inspected, cleaned, treated and locally redecorated, leaving the rooms cleaner, fresher and more presentable. The works also helped clarify the likely moisture source and any further ventilation or maintenance steps required.
