"Fascia replacement on our 1930s semi — the 1980s UPVC had finally given up. New run fitted with correctly calculated fall angles."
"1930s semi on Drayton Lane — re-roof, Portsmouth Roofing was honest that the tiles were past repair. Specified the correct modern equivalent."

Cosham sits at the northern approach to Portsea Island — slightly inland from the harbour but within the island's salt-influenced microclimate. Frost incidence is similar to Portsmouth generally but the 1930s semi concentration creates a specific repair profile across the suburb.
Cosham and adjacent Drayton are dominated by 1930s semi-detached properties — original concrete plain tiles now 85 to 90 years old and showing advanced surface aggregate erosion. Many properties are at or past the repair vs replace decision point.
Cosham new build work at the northern island approach requires coastal-adjacent specification — marine-grade stainless fixings and frost-resistant mortar for the dual salt and frost exposure at this transitional position. Every job we carry out in Cosham is specified for these specific conditions — not a generic Portsmouth-wide approach.
