Hi Jacqueline, I’d just like to say the 3 guys carrying out the work were brilliant, explaining what was going on and why. Faultless quality of work.
We are now saving for part two of the work.
Thanks so much.

I recently had new windows fitted in Tranent. The workers were on time, courteous, very neat and tidy and took away all the waste. The workers very politely refused any type of reward. I would have no hesitation recommending this company. Mr Mackie
Why should I replace my old windows?
Upgrading to modern A-rated windows can reduce draughts and heat loss, improve comfort, and help lower heating costs. You’ll also benefit from improved security, reduced outside noise, and a fresh new look for your home—ideal for properties in Linlithgow and across Scotland.
What does “A-rated” mean?
A-rated refers to a high level of energy efficiency. It means the frame, glazing and seals are designed to retain heat effectively and minimise heat loss, helping your home stay warmer for longer.
How do I know if my windows need replacing?
Typical signs include draughts, cold spots near windows, rattling in the wind, condensation between panes, stiff handles or faulty locks, visible gaps, or warped frames. If you’re unsure, CSJ can provide honest advice and a free, no-obligation quotation.
Will new windows help with condensation?
In many cases, yes. New sealed units and better insulated frames help reduce cold surfaces where condensation forms. Good ventilation is still important, but replacing older windows often makes a noticeable difference.
Can timber windows be repaired instead of replaced?
Sometimes—if the timber is structurally sound. However, where there’s rot, warping, persistent draughts, or ongoing maintenance, replacement is often the best long-term option.
Are older aluminium windows inefficient?
Older aluminium windows can be less thermally efficient than modern systems. Upgrading to today’s energy-efficient designs can improve warmth and comfort, particularly during colder Scottish months.
Will A-rated windows make my home warmer?
Most homeowners notice improved comfort quickly—less chill near the windows, fewer draughts, and more consistent room temperatures. A professional survey and installation are key to achieving the best result.
Can I keep the same style as my existing windows?
Yes. CSJ supplies bespoke windows in a wide range of styles, finishes and opening options to suit both traditional and modern homes, so you can keep the look you like while improving efficiency.
Do new windows improve security?
Modern window systems typically include upgraded locking mechanisms and robust frames, helping to improve security compared to older windows.
How long does installation take?
Timescales depend on the number and size of windows. Many installations can be completed within a few days. After a survey, we’ll confirm an accurate schedule and keep you informed throughout.
Will fitting new windows be disruptive?
We aim to keep disruption to a minimum. Our team works cleanly and professionally, protecting surrounding areas, removing old units carefully, and leaving a neat finish.
Do I need planning permission to replace windows in Scotland?
Most replacements do not require planning permission. However, listed buildings and conservation areas may have specific requirements. If you’re unsure, we can advise on the best next step.
What’s the first step with CSJ?
Simply get in touch to arrange a free consultation and no-obligation quote. We’ll discuss what matters most—warmth, security, noise reduction or appearance—and recommend the best A-rated option for your home in Linlithgow or anywhere across Scotland.
