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.
“We had constant draughts from our front bay windows and the double glazing had completely failed. I was worried we’d need total replacement but Hampstead Sash advised a sealed unit repair to preserve the existing frames. Their care, attention to detail and honesty saved us thousands. We now have warm, clear windows and zero noise. I wouldn’t hesitate to use them again.”
“Two of our double-glazed sash windows had cracked during the winter freeze. I contacted multiple companies but Hampstead Sash Window Repairs stood out. They were local, knowledgeable and genuinely helpful. They assessed everything the same day, provided a quote and the repair was done the following morning. The result? Clean finish, no mess, no upsell—just solid, professional work.”
“As a property manager of listed homes, I need tradespeople who understand regulations. Hampstead Sash Window Repairs & Emergency Glazing worked with our conservation team to upgrade old glazing without changing the outward appearance. The team worked quietly, respected the tenants and the new double glazing made a huge difference to warmth and condensation. A rare find in London.”
