Thank you so much!

just had the whole house fitted with windows and doors from SFG .From the moment I rang for a quote and spoke to a lovely lady called Frances. I then had the pleasure of meeting Tom the salesman a true honest gentleman who gave us all the options prices and estimated fitting date without being pushy he was so helpful. He delivered on everything .Raymond and John the fitters turned up on the date and on time and worked hard throughout the day .They cleaned up at the end of everyday nothing was too much trouble .They did an amazing job i am so pleased with my new windows and doors .I can't praise this company enough professional polite competitiveness prices I would definitely recommend this company it was a pleasure doing business with you Thankyou so much SFG .Keep up the good work!

cant praise SFG Windows highly enough

I cant praise SFG Windows highly enough. They are extremely professional, highly organised and have customer care in the bag. From my initial consultation with sales rep Tom who I immediately got a lovely feeling from as in he wasn't out to make a sale for sake of it, he was extremely honest and explained various options in what I was looking for in a new front door. Choosing my new door down to styles, window options for it and accessories was laid out as clear as anything. Once I made my choice , Paul in the office arranged for surveyors to do their exact measurements, who were a credit to SFG arrived on time and where extremely professional and polite. The only hard part of the process was waiting for the door to be built🙂. The team who came to fit my new door where again punctual, extremely well organised, clean and tidy and when the job was done didn't leave a speck of building dust behind. And last shout out goes to Frances in the office who called and kept me informed when the team or surveyors were due out and worked out date for installation and payment etc. To each of you, you made the whole process an absolute dream and I simply couldn't be more thrilled with my new door, so much so that my sister 5 doors down from me is getting her new doors from you too!! What a fantastic company and an utter pleasure to have done business with you. This business should be bench mark for others....100% satisfaction. Well done to EVERYONE 👍

will definitely use again

We are extremely satisfied with the quality of our patio door. Very tidy and professional workers. They ensured that after installation everything was cleaned and left in pristine condition. Friendly and polite people to deal with which makes a huge difference. I'm pleased to recommend SFG and will definitely use again. Thank you, very happy.
