Frequently Asked Questions
We’ve listed common questions with relevant answers below. All categories are listed alphabetically…
Do you offer a guarantee?
By adhering to strict quality guidelines and ensuring complete satisfaction with every installation, CSJ have become DGCOS members. As a result, this means that your installation comes with a 10-year insurance-backed guarantee.
Your guarantee remains valid in the unfortunate event CSJ was to cease trading for any reason.
How safe is my guarantee?
CSJ will provide every customer with a unique, insurance-backed 10-year guarantee free of charge. This ensures that your guarantee lives on even if CSJ should cease to trade.
Are similar guarantees safe?
Not necessarily. By being a DGCOS member, CSJ is backed by an insurer that offers much more than financial protection (read more). The guarantee also covers the customer if the company ceases to trade for any reason, not just insolvency. Furthermore the DGCOS provides free mediation and a free claims service. Other guarantee providers may charge for this.
Do you ask for a deposit?
For all window, door and roofline installations we do not request a deposit as there are generally no legal fees associated with this work (planning & building applications). However, for sunrooms and conservatories we do ask for a deposit in advance as legal applications are required for which we incur an immediate fee.
If I move house, does the guarantee cover the new owners?
Your guarantee can be transferred to the new owners – a great benefit to you when you wish to sell too! All we ask is that you let us know, in writing, within 28 days of moving to your new home.
How do I know I can trust CSJ?
DGCOS members become part of the scheme on an invitation-only basis. We’re one of three companies in Scotland to be members. Every DGCOS member company must adhere to strict standards and is vetted to ensure it has good financial stability and working practices before being allowed to join. Only those companies that uphold the standards are allowed to continue as members.
Furthermore, we have scanned testimonials of some of our customers and unrivalled reviews on independent websites. Please see our testimonials page for more information.
What policies, if any, do you have in place to minimise the impact on the environment?
Absolutely! Please see our environment page for more information.
What areas of Scotland do you cover?
We’re proud to offer our services throughout Scotland, so whether you’re in John o’Groats or Galashiels we’ll visit you!
Can I trust the quality of materials used for my installation?
All frames used by CSJ are not only made of extrusion products from Veka directly, but also manufactured by a Veka fabricator member, to ensure the quality and designs are second to none. All profiles are made from virgin uPVC, meaning we do not use recycled products. Furthermore, we source all timber from FSC certified members.
How do you finish the windows and doors on the inside of my property?
A full timber finish is provided. Due to this, we take great care when choosing our timber supplier and where possible, all our timber is sourced from local, well-managed forests that are governed by accredited programs.
Do you offer prices online?
The simple answer is no, and we’ve dedicated a part of our website explaining why. Please see our cost of home improvements page for more information.
We hope the questions and answers above highlight the reliability and security that comes with your installation. Should you have a question that is not answered here, please get in touch.
