With over two decades of hands-on expertise, we’ve worked across Highgate’s finest Victorian, Edwardian and Georgian homes. Whether you’re dealing with cracked panes, draughty timber sashes or a glazing emergency at midnight, our team responds quickly, works precisely and respects the integrity of every property. Our solutions don’t just fix—they preserve, protect and elevate the architectural charm of your home.
We understand that when you invite a tradesperson into your home, you expect more than a basic fix—you want deep technical knowledge, certified workmanship and honest service. Here’s how we deliver that, every time:
We don’t just work on windows—we restore heritage. Our team is trained in traditional joinery and glazing techniques, ensuring every job is sympathetic to original features. We carefully match profiles, timber types and putty lines, particularly vital in conservation areas like Highgate.
We’ve completed hundreds of projects across Highgate’s leafy avenues, listed townhouses and apartment buildings. Our experience translates into faster diagnosis, cleaner results and fewer disruptions for homeowners and residents.
We’re members of the Glass & Glazing Federation (GGF), FENSA-registered for compliant window works and carry comprehensive public liability insurance. We follow Building Control and heritage regulations to the letter, giving you full compliance peace of mind.
With glowing reviews from architects, landlords and residents alike, we’ve built a name synonymous with quality. We’re trusted local tradespeople with over 20 years of experience.
We provide a full suite of window restoration and glazing services tailored to Highgate’s property styles and conservation expectations. Our approach is always sensitive to the age, style and condition of each property.
We repair original sash windows suffering from rot, broken cords, seized pulleys and misaligned sashes. Each repair is carried out with minimal disruption, using reclaimed or matched materials to preserve authenticity. We also handle rattling, flaking paint and timber decay.
Our restoration work goes beyond cosmetics—we assess structural integrity, treat wet or dry rot, reinforce or replace decayed sills and reinstate ventilation to prevent future issues. Restoration is particularly vital in Highgate’s older properties, where replacement options are often limited due to access or preservation requirements.
A proper draught-proofing system can make a night-and-day difference in comfort. We install discreet brush seals, parting beads and meeting rails that keep warmth in and cold out, without affecting the look or movement of your windows.
Windows can break at the worst possible time. That’s why our emergency response team is available 24/7. We board up broken panes, clear up shards and return swiftly with a like-for-like replacement glass to secure your home or rental flat.
From accidental impact damage to vandalism, we replace all types of window glass, including single-glazed, laminated safety glass and heritage float glass. We ensure thermal performance and visual match for traditional properties.
A stuck sash can ruin a room’s airflow. We repair and replace frayed or snapped cords, rebalance sash weights and clean runners to restore smooth and silent function to sliding sashes, while retaining all original components where possible.
In cases where repair isn’t feasible, we offer full heritage-compliant replacements. Our custom-made sash windows are handcrafted to match original designs, using the correct mouldings, sightlines and glazing bars. Ideal for homes in listed buildings and conservation areas.
Slim-profile double glazing can be installed into existing or replica timber frames. This allows you to improve insulation, security and noise control without breaching heritage aesthetics. We'll help you navigate the permissions process and explore all available options.

At Hampstead Sash Window Repairs & Emergency Glazing, our working method is structured, efficient and respectful of heritage detailing. Every step is designed to ensure quality results for homes and buildings across Belsize Park.
Step 1: Consultation and Scheduling
We begin with a quick call or online form submission. Once we identify the problem, such as a cracked pane, condensation or shattered glass, we arrange a convenient time for inspection. Emergency cases are prioritised for same-day response.
Step 2: Site Inspection and Diagnosis
One of our specialists will visit your property to inspect and assess. We check the sash, frame integrity, beading, putty and glazing lines. This ensures that any underlying structural issues are identified early.
Step 3: Quotation and Material Matching
We provide a clear, fixed quote tailored to the glass type required, whether single glazing, laminated or heritage-compatible. Materials are carefully matched to maintain the original aesthetic and meet regulatory standards.
Step 4: Precision Repair or Replacement
We safely remove the damaged glass, prepare the surrounding timber and install new glass using traditional glazing techniques. Every detail is considered, from edge sealing to sash realignment, ensuring longevity and insulation.
Step 5: Final Checks and Client Sign-Off
We finish by testing sash movement, cleaning the work area and ensuring airtight sealing. Our clients are walked through the finished result and we offer guidance on aftercare and future maintenance if needed.

The difference is amazing—our living room now stays warm and there’s no rattling during storms. The team was tidy, polite and knew their craft. Would use again in a heartbeat."

Great service and very responsive.”
