What are you trying to fix?
If you already know what is wrong, jump straight to the type of question most relevant to you.
Questions about replacing old or inefficient windows.
How do I know if my windows need to be replaced?
Look for condensation between panes, draughts, rising energy bills, sticking windows, visible cracks, poor sound insulation, damaged frames or windows that no longer close securely. In some cases, the full window may need replacing. In others, glass, seals or hardware may be enough.
Do I always need to replace the full window?
No. If the frame is still in good condition, you may only need replacement glass, new seals, hinges, handles or locks. Full replacement is usually more suitable when the frame is worn, inefficient, damaged or no longer performing properly.
What types of windows do you install or replace?
Common options include uPVC windows, aluminium windows, casement windows, tilt and turn windows, sash-style windows and roof windows. The right choice depends on the property, budget, appearance, energy goals and existing frame condition.
Can replacing windows make my home warmer?
Yes. Modern windows and properly fitted glazing can reduce draughts, improve comfort and help reduce heat loss. The result depends on the existing windows, the type of replacement chosen and the quality of installation.
Can new windows improve security?
Yes. Modern locking systems, stronger frames, secure glazing and improved hardware can all help improve home security. If your current windows are difficult to lock or close, it is worth getting them assessed.
Questions about misted, cracked or failed glass units.
Can misted double glazing be replaced?
Yes. Condensation or fogging between the panes usually means the sealed double-glazed unit has failed. In many cases, the glass unit can be replaced while keeping the existing frame.
What is the difference between double and triple glazing?
Double glazing uses two panes of glass with an insulating gap between them. Triple glazing uses three panes and can offer improved insulation, sound reduction and comfort in certain homes. The best option depends on the property, budget and performance goal.
Do you offer glass-only replacement?
Yes. If the window frame is still sound, glass-only replacement can be a practical option for cracked glass, failed double glazing, misted units or certain damaged panes.
Do you replace toughened or laminated safety glass?
Yes. Toughened and laminated glass can be required for doors, side panels, low-level glazing, shopfronts and safety-focused areas. The correct glass type depends on where it is being fitted and what it is used for.
Can you provide custom glass solutions?
Yes. Custom glass cutting and installation can be arranged for non-standard sizes, feature glazing, unusual window shapes, repairs, replacements and specialist glazing needs.
Questions about draughts, hinges, handles, locks and seals.
My window will not close properly. Can it be repaired?
Often, yes. The issue may be caused by hinges, alignment, handles, locking mechanisms or worn seals. A full replacement may not be needed if the frame and glass are still in good condition.
Can draughty windows be repaired?
Sometimes. Draughts can come from worn seals, poor alignment, failed hinges or ageing frames. The best solution could be new seals, hardware repairs, glass replacement or full window replacement depending on the condition.
Do you replace window locks, handles and hinges?
Yes. Faulty locks, broken handles, worn hinges and damaged hardware can often be replaced to improve security, usability and day-to-day performance.
Can window repairs improve energy efficiency?
Yes, in some cases. Replacing seals, repairing hardware and addressing draughts can improve comfort. If the glass or frame has failed, a replacement unit or full window upgrade may be more effective.
Do you work with commercial buildings?
Yes. Glass replacement and glazing support can be provided for shops, offices, apartments, landlords, property managers and commercial buildings, including shopfront glass, safety glass and replacement panes.
Questions about cost, timing and local coverage.
How much does window replacement cost?
Cost depends on the window size, frame type, glass type, number of windows, access, materials and whether the job is a repair, glass-only replacement or full replacement. The best way to get a realistic price is to send details and photos.
How long does installation take?
Many smaller glass or repair jobs can be completed quickly once materials are ready. Full window replacement timelines depend on measuring, ordering, access, the number of windows and the scope of work.
What areas do you cover?
Key service areas include South Dublin and Wicklow, including Rathfarnham, Blackrock, Ballinteer, Dundrum, Killiney, Sandyford, Bray, Greystones, Delgany, Wicklow Town and Rathnew. The site is also being expanded for wider Leinster coverage.
Should I send photos before requesting a quote?
Yes. Photos are very helpful. Send pictures of the window, glass, frame, lock, hinge, seal, damage or misting. This helps the team understand whether it is likely to be a repair, glass replacement or full replacement.
How can I get a quote?
Call the team, email your details or use the contact page. Include your location, the type of issue, how many windows are involved and photos where possible.
