UPVC Vertical sliding sash windows


For many years now, we’ve been busy helping residents throughout Scotland with new and upgraded vertical UPVC sliding sash windows.  We’re always proud to help keep people’s houses looking good and warm through our double glazing advice service.  All windows that we fit are A-rated and comply with all the necessary current building regulations.  They also come with a 10 year insurance-backed guarantee, giving you peace of mind.

Here’s an example of a recent job that one of our vetted installers recently completed in Central Scotland, achieving an almost perfect match to the existing timber sash windows.

The internal finish was completed in UPVC and gives the owner an almost maintenance-free product.

The image below shows how you can retain a traditional appearance for your home.  The upstair windows are 8 days old….the downstairs are 80 years old!

What are our customers saying about our double glazing advice?

What a breath of fresh air – no salesmen in my home – just sound information from a Surveyor who returned with 6 quotes from vetted companies for me to choose from. This is definately the way to purchase Double Glazing.

Having the Advice Centre’s knowledge behind you, gives you total confidence. A great service and I would recommend them to anybody who is thinking of purchasing Double Glazing. Many thanks

I booked an appointment with and Advisor who didnt try to sell me anything. He helped us design and style our windows. After an excellent, hassle free fitting, they came back to inspect the work carried out – Highly recommended

I would like to thank all your staff at the double glazing advice centre on delivering exactly what they said on the tin to my parents. Initially my parents were unsure of allowing any double glazing sales person into their homes, as they thought they would be pressurized into making a decision there and then without being allowed to discuss their options with myself before continuing.The process that the Double Glazing Advice Centre followed was simple, efficient, thorough and most of all totally independent from their vetted installers quotes. The ensured that the job was completed in a timely manner and that my parent where totally satisfied with the installation before asking for the final payment. Thanks again for a fantastic service and i would be happy to recommend you to all of my friends and family in the future

I recently used the double glazing advice centre to install my 8 double glazed windows and a front door at my house. After having several high pressure sales people from other companies which left me really angry, and thankfully i was recommended to speak to these guys. From first visit and then going through the estimates i was always at ease and never put under pressure. The service from DGAC was exactly as they said they would deliver from start to finish and would not hesitate in recommending them to any person who is needing either new windows and doors to their property. from looking at the five quotes they put in front of me, the price i picked was still £500 cheaper than quoted from the others. Fantastic system and thank you once again for everything.
