Frequently Asked Questions
How long have you been working in the sash window industry?
We have been serving the Surrey community since 2001.
What area do you work in?
We work throughout Surrey and London.
How clean will my property be left after work?
On every job we lay out dust sheets and place carpet on top of any wood or tile flooring to prevent any damage; and all power tools are connected to vacuums to tackle spreading of dust.
How long will a job take?
It depends on the complexity of the job, but for example a complete replacement can be completed in one day. For a more specific timetable give us a call to discuss your requirements.
How do I know that I can trust your service, are you officially recognised by anyone?
We have years of experience in the business and are officially recognised by:
The Guild Of Master Craftsmen
…and we are also a member of Checkatrade where we encourage you to read our many positive reviews.
Do you undertake small repairs? For example a broken cord or broken glass?
No job is too small and we are just as happy to hear from you regardless of the job being large or small.
Is it possible to replace single glazed sash windows with double glazed sash windows?
In many cases it is possible to replace just the sashes from single to double glazed without having to replace the entire box frame. If not then we can undertake a complete replacement to comply with relevant building regulations.
I am a bit confused about the different types of double glazing that is available, can you help?
Yes we know that it can indeed be confusing, but don’t worry we have years of experience and will be happy to talk you through the different options available that will best suit your requirements.
Do you work with any other types of glass?
Yes, we often fit a variety of different types of glass. For example glass specialising in thermal insulation or frosted glass for privacy.
Some sash window companies install budget frames, what does SJB provide?
SJB Sash Windows offer the highest quality of products and service on the market today, but at prices you can afford. We encourage you to get in touch for more details on our products.
Are you windows guaranteed?
Yes. All our sash windows are fully guaranteed.
I live in a listed building and / or conservation area, are you able to work on my windows?
We are very experienced in dealing with such red tape and restrictions. We will talk you through exactly what can and can’t be done.
What wood do you use?
We use timber sourced from sustainable sources and we match any moulding or profile to blend in with your existing sashes.
Can you replace broken springs / spiral balances?
Yes. For those of customers who have spiral / spring balancers instead of sash cords with weights we would make a site visit to take measurements and ensure the correct replacement is sourced.
