Services
Window Repair
Our specialist window repair service addresses rot and decay in heritage timber frames using traditional techniques combined with modern strengthening methods. We preserve original features while enhancing structural integrity and thermal efficiency. Each restoration follows our patented Longaevitas process to ensure centuries of additional lifespan for your windows.
Door Restoration
Comprehensive door restoration that maintains historical authenticity while improving functionality. Our process removes decayed timber, reinforces structural weak points, and modernises mechanisms without compromising original design elements. This service extends the lifespan of heritage doors while enhancing security and insulation properties.
Glass Replacement
Retro-glazing solutions that upgrade original windows with modern glass options for improved security, noise reduction, and thermal efficiency. We install double glazing and specialist glass while maintaining traditional aesthetics, ensuring compliance with conservation area requirements and listed building regulations.
Furniture Replacement
Authentic period-appropriate hardware replacement for windows and doors. Our selection includes traditional pulleys, handles, and decorative elements that enhance functionality while maintaining historical accuracy. These upgrades improve operation smoothness and visual appeal without compromising heritage integrity.
Lead Paint Removal
Safe removal of hazardous lead-based paints from heritage windows and doors conducted entirely in our controlled workshop environment. This process eliminates health risks while preparing surfaces for durable, eco-friendly finishes that preserve timber integrity and maintain period-appropriate appearances.

Report
Having a bad time getting any response from this company following restoration on my door 9 months ago which is already cracking and peeling. I think they may be in liquidation.

Report
We were looking to have our sash windows repainted internally but wanted to use a specialist company who would 'understand' windows. We couldn't have been happier with the service we received from Fortis & Hooke. From the initial enquiry to the finished product we received exemplary service and I would have no hesitation in recommending Fortis & Hooke.
