At The Southsea Decorating Company, we provide professional sash window refurbishment and redecoration for commercial buildings, landlords, and developers across Southsea, Portsmouth, Winchester and the wider Hampshire region. From heritage apartment blocks and listed offices to boutique hotels and schools, we understand the importance of maintaining both appearance and performance.

Sash windows are often a defining feature of commercial and period buildings, and our specialist team is trained to restore them with minimal disruption. We repair, reglaze, and redecorate using high-performance materials that ensure long-lasting results — protecting your investment while keeping properties compliant and visually impressive.

Our decorators and joiners carry out detailed repairs including:

Timber splicing and two-part resin restoration for decayed frames

Draught proofing and re-cording

Glass replacement and putty glazing

Spray or brush finishing using professional-grade coating systems

We know sash window refurbishment like the back of our hands

We recently completed a large-scale sash window refurbishment for a local property management company in Portsmouth. Working to a tight schedule, we repaired over 30 windows, bringing them back to perfect working condition and applying a robust, weather-resistant paint system that will keep them protected for years.
