This firm did a superb job with our patio doors and window. Frazer and Aaron were very polite and friendly and completely professional. They worked continually, even in the rain. They made sure it was working completely fine before they left, and they left the area clean and tidy. I would highly recommend them.

We have used Frazer at Origin for a couple of projects previously so I knew who do go to when I wanted my own windows & doors replaced in my property.
Frazer has been excellent from start to finish & given such peace of mind with his knowledge & expertise around all the products from initial stages to the completed product. His eye for detail & finish is top notch & I would highly recommend Frazer.

We recently hired Frazer for a new door and side window and we could not be happier with Origins service. Frazer was professional, punctual and efficient and his customer service was second to none.
Origin Double Glazing are reliable, honest and I would recommend them to anyone who is looking for great window fitters.

Frazer came out to measure up and sent a quote over promptly. I had many questions about functionality and regulations, and he was very accommodating, taking the time to answer every one of them.
The windows and doors were fitted, the rendering completed, and all rubbish removed from the house. I couldnt be happier with the result.

Very professional service. Old PVC door removed and new replacement fitted and we are delighted with the result. Highly recommend Origin Double Glazing Ltd. Very clean and tidy workmanship, especially as it was heavy rain that day. Quality of replacement door is excellent, now shuts and locks with ease. Thank you, will definitely use again
