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Outdated window design not only affects appearance but may lack modern insulation.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Homeowners may seek aesthetic updates, addressing outdated designs lacking clarity and security.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.
05Trim and seal around each window to prevent drafts and moisture ingress, ensuring the windows' long-term durability.

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:

The choice of materials, such as uPVC or timber, impacts cost due to differing manufacturing and durability factors.
Complex window shapes, like bay or bespoke designs, typically increase labour and material costs due to customisation needs.
Historical or listed buildings often require specialised windows, increasing costs due to regulation compliance and custom work.
Installation complexity varies with accessibility of window locations, requiring more labour and potentially specialised equipment.
Additional insulation requirements or energy-efficient glazing specifications lead to higher costs but offer long-term savings.
Local labour rates and installer expertise significantly impact overall costs, with experienced providers offering reliability.

Questions

What should I check for window installation compliance in the UK?

Ensure your window installation complies with UK Building Regulations, particularly for insulation (Part L) and security (Part Q). Verify that either the installer is FENSA certified or that a local authority inspection will occur. Understanding compliance ensures energy efficiency and safety are maintained. Ask the installer what is included in their service concerning regulations and check for tangible proof of quality assurance.

Why are my new windows causing drafts or noise?

Drafts or noise from new windows often indicate issues with sealing or improper fitting. Check if the frames are properly aligned and that all seals and edges are intact. Insufficient sealing will allow air and sound to penetrate, compromising insulation qualities. Professional assessment can identify if the problem stems from a manufacturing defect or an overlooked installation issue, necessitating corrective action.

Should I repair or replace old windows?

Consider repair if the windows are slightly damaged, and the frames are in good condition. Replacement is preferable when dealing with extensive frame rot, persistent drafts, or failing seals. Modern replacement windows offer better energy efficiency, security, and aesthetic appeal. Weighing repair costs against potential savings from improved insulation often guides the decision to invest in new, high-performance windows.

What are the regulations for adding new windows to a home extension?

New windows in home extensions must comply with UK Building Regulations for energy performance and safety. Specifically, Part L addresses energy conservation, and Part Q focuses on security. Considerations for privacy, light, and restricted opening for safety in certain locations may apply. Always consult with building control or a professional installer to ensure all regulations are met before proceeding with the installation process.
