The Role

This is a full-time, field-based role for a Window & Door Service Engineer (Surveying & Repairs) providing service and repair coverage across Greater London.

The role involves surveying, servicing, and repairing a wide range of window and door systems, combining detailed inspections with high-quality technical repair work. You will be expected to work to defined standards, follow agreed processes, and deliver consistent, reliable outcomes across all assigned jobs.

The position requires an engineer who is comfortable working independently on site, takes ownership of their work, and maintains clear communication and documentation throughout each stage of delivery.

Essential Requirements

To be successful in this role, you will need to demonstrate the ability to deliver both surveying and engineering responsibilities to a high professional standard.

You must have

• Proven experience surveying, diagnosing, repairing, and replacing components across a wide range of window and door systems, with the ability to work independently on site, manage jobs end-to-end, and take ownership of outcomes.
• Strong inspection and fault‑finding capability, including taking accurate measurements, assessing system condition and performance, and determining appropriate repairs, adjustments, or replacements.
• Hands‑on experience completing repairs and replacements, including hinges, handles, locks, cylinders, operating mechanisms, and multi‑point locking systems, with strong locksmith capability.
• Practical experience working with uPVC, aluminium, timber, and aluminium‑clad timber systems, including tilt‑and‑turn, tilt‑and‑slide, lift‑and‑slide, sliding, casement, and sash systems, and with premium brands such as VELFAC, Rationel, and Idealcombi.
• Confidence producing clear written inspection and completion reports that set out findings, required works, and outcomes, with a strong focus on quality, safety, and precision.
• A full UK driving licence, own hand and power tools suitable for window and door service and repair work, and the ability to work full contracted hours consistently.

How the Role Is Delivered

Repairs, Remedial Works & Completion

This role is primarily focused on the delivery of high‑quality repairs and remedial works. You will be responsible for carrying out approved repairs accurately, efficiently, and to a consistently high professional standard, ensuring all windows and doors operate safely, smoothly, and as intended.

Repair works include mechanical adjustments, glazing replacements, sealing works, and the installation of associated remedial measures. You will take full ownership of job completion, including confirming works carried out, recording materials and labour, and providing photographic evidence where required.

Surveys, Specification & Technical Diagnosis

You will carry out structured inspection surveys to accurately diagnose faults, assess system condition and performance, and specify the correct materials and labour required to complete repairs properly first time. Survey accuracy and clear reporting are essential, as repair works are costed and approved based on your findings.

Systems, Hardware & Locksmith Work

The role involves regular work on complex operating and locking hardware. You will be expected to adjust, repair, and replace operating mechanisms and locking systems across uPVC, composite, aluminium, and timber doors and windows.

This includes work on tilt‑and‑turn hardware (hinges, gearboxes, and operating mechanisms), sliding, lift‑and‑slide, and bi‑fold door systems (rollers, tracks, carriers, and locking components), as well as hinges, restrictors, shoot bolts, cylinders, and operating handles where required.

You must be confident diagnosing faults, identifying the correct replacement components, and fitting or adjusting hardware to ensure smooth, secure, and reliable operation in line with system and manufacturer requirements.

Suitable Relevant Trade Backgrounds

Suitable Backgrounds

We are open to candidates from a range of relevant trade backgrounds, provided they can meet the essential requirements of the role. Suitable backgrounds may include :

• Experienced window and door service engineers
• Multi‑trade or glazing engineers with strong window and door repair experience
• Carpenters or aluminium installers with demonstrable experience repairing, adjusting, and fault‑finding on windows and doors

You do not need to meet every requirement on day one. Candidates transitioning from related trades will typically start at the lower end of the pay band, with clear progression as window and door‑specific service, diagnostic, and locksmith skills develop. What matters most is technical aptitude, reliability, and a willingness to work to high service and quality standards.

Pay progression is reviewed following the probationary period and is linked to reliability and timekeeping, technical competence, accuracy of surveying, reporting, estimating, and overall independence and quality of work.
