How To Seal Double Glazed Windows

How To Seal Double Glazed Windows: A Guide for Hard-to-Reach Locations

Double glazed windows are a staple of modern buildings, offering improved energy efficiency, noise reduction, and comfort. However, over time, the seals around these windows can degrade, leading to draughts, condensation between panes, and loss of insulation. Sealing double glazed windows is essential for maintaining their performance, but the task can become particularly challenging when windows are located in hard-to-reach places—such as upper floors of commercial buildings, residential blocks, or industrial structures.

At [Corded.uk](https://corded.uk), we specialise in providing rope access solutions for building maintenance, including window sealing, in locations where traditional access methods like scaffolding or cherry pickers are impractical or disruptive. Here’s a comprehensive guide on how to seal double glazed windows, especially when access is a challenge.

Why Seal Double Glazed Windows?

The seal around double glazed windows is crucial for several reasons:

– Thermal Efficiency: A proper seal prevents heat loss and keeps energy bills down.
– Moisture Control: Seals keep moisture out, preventing condensation and potential mould growth.
– Noise Reduction: Good sealing maintains the window’s soundproofing properties.
– Structural Protection: Prevents water ingress that can damage window frames and building fabric.

Signs Your Double Glazed Windows Need Resealing

Before starting, identify if your windows need attention. Common signs include:

– Condensation or fogging between the glass panes.
– Noticeable draughts near the window frame.
– Visible cracks or gaps in the existing sealant.
– Peeling or deteriorated sealant around the window exterior.

The Sealing Process: Step-by-Step

1. Assessing Access Requirements

For windows on upper floors or in difficult locations, rope access is a safe, efficient alternative to scaffolding or powered platforms. Rope access technicians at Corded.uk are trained to work at height, ensuring minimal disruption to building occupants and the surrounding area.

2. Safety Preparations

Safety is paramount. Before any work begins, our team conducts a risk assessment, plans anchor points, and ensures all rope access equipment is inspected and certified. We cordon off the work area below to protect pedestrians and property.

3. Inspection and Preparation

– Visual Inspection: Our technicians inspect the window and surrounding frame for damage.
– Cleaning: The area around the seal is cleaned to remove dirt, old sealant, or debris. This ensures new sealant adheres properly.
– Removing Old Sealant: Any loose or degraded sealant is carefully removed using suitable tools, taking care not to damage the frame or glass.

4. Selecting the Right Sealant

For double glazed windows, a high-quality, weatherproof silicone or polymer-based sealant is recommended. The sealant must accommodate movement and provide long-term durability against the UK’s varied weather conditions.

5. Applying the New Sealant

– Preparation: The nozzle of the sealant tube is cut to the desired bead size.
– Application: Using a caulking gun, a continuous bead of sealant is applied around the perimeter of the window, ensuring all gaps are filled.
– Finishing: The sealant is smoothed with a finishing tool or gloved finger for a neat appearance and to ensure proper adhesion.

6. Final Checks

Once the sealant is applied, our technicians perform a final inspection to ensure all areas are properly sealed and there are no missed spots. Excess sealant is cleaned away, and the work area is tidied.

Why Use Rope Access for Window Sealing?

Traditional access methods like scaffolding or cherry pickers can be costly, time-consuming, and disruptive—especially in busy urban environments. Rope access, as offered by Corded.uk, provides several advantages:

– Minimal Disruption: No need to block pavements or erect large structures.
– Speed: Projects are completed faster, reducing downtime for building occupants.
– Cost-Effective: Lower labour and equipment costs compared to scaffolding.
– Safety: Rope access is statistically one of the safest methods for working at height when performed by trained professionals.

When to Call the Professionals

While minor window sealing jobs at ground level can sometimes be tackled by DIY enthusiasts, any work at height or in difficult-to-reach locations should always be carried out by qualified rope access technicians. This ensures not only the quality of the repair but also the safety of everyone involved.
