Restore Performance with Professional Window and Door Repairs
Expert repair services for uPVC and aluminium windows and doors. Secure, efficient and carried out to the highest standards.
Windows and doors are built to last, but over time components can wear out, seals can fail and locks can become stiff or faulty. When problems develop, it does not always mean full replacement is necessary. In many cases, professional repair can restore performance, improve security and extend the lifespan of your existing units.
At Carreg Fawr, we provide specialist window and door repair services for domestic properties. With structured quality processes and experienced technicians, we assess each issue carefully and recommend the most practical solution. Our goal is to restore functionality, improve safety and ensure your windows and doors continue to perform as they should.
If you are experiencing draughts, difficulty locking doors or visible wear, our repair service offers a dependable and cost effective solution.
Common Window and Door Problems We Repair
Over time, regular use and exposure to the elements can affect moving parts and seals. Identifying issues early can prevent further damage and improve long term performance.
Faulty Locks and Handles
Locks and handles are used daily, and internal mechanisms can wear or become misaligned. A stiff key, loose handle or door that fails to lock properly is not only inconvenient but can compromise security.
We inspect locking systems, replace worn components and ensure correct alignment so that windows and doors operate smoothly and securely. Restoring proper locking function improves both safety and ease of use.
Hinges and Alignment Issues
Windows and doors can drop slightly over time due to weight and regular operation. This may cause rubbing against frames, difficulty closing or visible gaps around seals.
Our technicians adjust hinges, realign frames and replace worn hardware where necessary. Correct alignment ensures smooth operation, proper sealing and reduced strain on components, helping to prevent further wear.
Failed or Damaged Seals
Perimeter seals play a vital role in insulation and weather protection. When seals degrade, you may notice draughts, water ingress or increased external noise.
We assess the condition of existing seals and replace them where required. Restoring effective sealing improves thermal performance and helps maintain a comfortable indoor environment throughout the year.
EXAMPLES OF PREVIOUS INSTALLATIONS









Repairing uPVC Windows and Doors
uPVC systems are durable, but they still rely on mechanical components that can require maintenance over time. Professional repair can often restore performance without the need for full replacement.
Addressing Draughts and Heat Loss
If you feel cold air entering around your frames, the issue may relate to worn seals or misalignment. By correcting these faults, we help improve insulation and reduce unnecessary heat loss.
Careful inspection allows us to identify whether adjustments, seal replacement or minor component changes are needed. Restoring the system correctly helps improve comfort and energy efficiency.
Replacing Damaged Hardware
Handles, hinges and locking points can wear with regular use. Replacing these components with compatible parts restores smooth operation and extends the life of your windows and doors.
Using quality replacement parts ensures continued security and reliability. Proper fitting prevents recurring problems and maintains structural integrity.
Restoring Operational Performance
Windows that stick or doors that feel heavy to operate can indicate alignment or hardware issues. Our repair service focuses on restoring correct movement and secure closure.
By addressing operational problems early, homeowners can avoid more extensive damage and maintain reliable day to day use.
Aluminium Window and Door Repairs
Aluminium frames are known for strength and stability, but moving parts and seals can still require attention over time. Professional repair helps maintain long term performance.
Locking System Maintenance
Multi point locking mechanisms in aluminium doors must operate correctly to ensure security. We inspect and replace worn locking components where required, restoring proper engagement and reliable closure.
Correct alignment and adjustment are essential to prevent unnecessary strain on locking systems. Our technicians ensure each component functions as intended.
Track and Roller Adjustments
Sliding doors and bifold systems rely on smooth track and roller mechanisms. If panels feel difficult to move or appear misaligned, adjustment or replacement may be needed.
We carefully inspect rollers and tracks, removing debris and replacing worn parts. Restoring smooth operation ensures safe and effortless use.
Seal and Weatherproofing Repairs
Weather seals can degrade due to age or exposure. Replacing damaged seals improves insulation and helps prevent water ingress.
By maintaining effective sealing, aluminium systems continue to perform reliably and protect your home from the elements.
