Short answer
Verify that your chosen window installer covers building regulations compliance, either through FENSA or local authority. Ensure the service includes checks for current frame issues and improvements in insulation and security. If creating new window openings, differentiate these from simple replacements, considering potential structural work requirements.
Prioritise immediate replacement if windows compromise security or allow excessive heat loss.
Replacement windows and external doors in England usually need building-regulation compliance (FENSA or the local authority). Ask what is included.

How to recognise it
- Drafty windows allow heat to escape, indicating poor insulation or degraded seals.
- Excessive external noise entering suggests thin glass panes or faulty sealing.
- Visible condensation between double-glazed panes points to a failed internal seal.
- Outdated window design not only affects appearance but may lack modern insulation.
- Rotting frames indicate water damage, potentially compromising window structure and safety.
- Difficulty in opening or closing suggests frame warping or internal mechanical failure.
- Cold spots near windows highlight gaps in insulation, often leading to higher energy bills.
Common causes
- Severe weather exposure accelerates frame deterioration, weakening insulation and structural effectiveness.
- Ageing window materials warp and lose integrity, reducing their sealing capability and efficiency.
- Modern energy-efficiency standards often necessitate window upgrades for optimal insulation.
- Homeowners may seek aesthetic updates, addressing outdated designs lacking clarity and security.
- Building extensions or new construction require new windows to match updated architectural designs.
What you can do yourself
- 01Count all window openings and note types like bay or casement, which assists in planning installation logistics.
- 02Confirm if trickle vents are included in window designs to maintain ventilation without sacrificing efficiency or security.
- 03Ensure bedrooms have windows that meet fire-escape accessibility standards to comply with safety regulations.
What the glazier does
- Conduct a professional survey to identify drafts and propose appropriate window replacements tailored to specific needs.
- Custom-manufacturing windows ensures they perfectly fit each opening, enhancing insulation and providing increased security.
- Professional installation resolves fitting issues and ensures compliance with building regulations, crucial for long-term efficiency.
- Securing and sealing newly installed windows eliminates drafts and moisture ingress, improving home comfort significantly.
- Perform final quality checks to confirm each window meets relevant standards for insulation and operational functionality.
How the job usually runs
- 01Conduct a detailed survey to assess needs and inform the bespoke manufacture of windows, addressing specific issues identified.
- 02Order custom windows crafted for a precise fit and design, meeting particular insulation and security requirements.
- 03Remove existing frames carefully to avoid damage, fully preparing the openings for the fitting of new windows.
- 04Fit and secure new windows to ensure proper alignment, optimised insulation, and compliance with relevant regulations.

What the price depends on
FirstGlass Windows does not publish a fixed price. That is agreed with the firm you appoint. Differences usually come from:
- Material choice affects cost significantly, as uPVC, aluminium, and timber offer different durability and maintenance needs.
- The number and complexity of windows influence price, as more intricate designs like sash or bay require precise installation.
- Regulation compliance costs can vary if additional structural work or modifications are needed to meet standards.
- Customisation level affects pricing, with bespoke designs tailored for size or style contributing to overall expenses.
- Installer expertise can drive costs, as experienced professionals may charge more for higher-quality, reliable services.

Questions
What should I do if my windows are drafty?
Drafty windows likely require sealing or replacement to improve insulation and reduce energy bills. Conduct a thorough inspection to identify gaps or deteriorating seals. Consult a professional for a window survey to assess the condition and recommend suitable solutions. Timely action prevents further heat loss and enhances overall home comfort. Consider upgrading to modern, energy-efficient windows if repairs are insufficient.
How can I assess the severity of condensation between window panes?
Condensation between panes usually indicates a failed double-glazing seal, compromising insulation. Check for persistent moisture or misting that doesn’t clear, as these symptoms often signal seal failure. Assess the impact on heating by feeling for cold spots nearby. Replace affected units promptly to maintain efficiency, comfort, and clarity. Seek professional advice for long-term solutions if multiple units show signs of failure.
Are new window installations subject to building regulations?
Yes, new window installations must comply with UK Building Regulations, focusing on energy conservation (Part L) and security (Part Q). Ensure your installer follows the necessary procedures, either through a FENSA-registered company or local authority approval. Compliance ensures thermal performance standards are met, improving energy efficiency and safety. Check that the installation includes documentation verifying adherence to these regulations.
What should a window installation quote cover?
A comprehensive window installation quote should include material types, installation methods, and compliance with building regulations. It must outline whether custom measurements and manufacturing are part of the service. Confirm if the quote covers removals of old frames, quality checks, sealing processes, and post-installation inspections. Ensure clear communication of any additional costs for structural adjustments or unique design features to avoid unexpected expenses.
