Renewal of double glazing

AGS have just renewed all our windows and doors apart from the front door which we’d had done a couple of years ago. We would definitely recommend AGS. Andy’s quote was straightforward with no messing about and didn’t take hours like some companies. Once we’d accepted the quote the surveyor came to measure up, everything was ordered and we very quickly had an installation date. The installation team arrived early on the planned day and worked hard. The job was finished in three days as promised at the beginning even though three panes of glass had broken at the depot - these were ordered and arrived in time to be installed without the job being delayed. The team were friendly, worked hard and cleared up very well each day. We were impressed with the attention to detail given to the job.

Kitchen door and side windows with new double glazed unit
AGS fitted about 8 years ago 3 double glazed windows in my flat and as I recently wanted to replace a kitchen door and side windows with new double glazed unit in my house, I remembered the quality of the work that had been done in my flat and thought I would contact AGS for a quote. The entire process was truly seamless with a market value quotation and very good quality double glazing materials. The fitting was excellent and we are all very happy with the new unit at home. This is a team of people ( a family business) that work extremely well in terms of communication, punctuality, competence and experience. You will not be disappointed if you book AGS to improve your residence.

Bay Windows Front Door

New Bay windows and Endurance Front door fitted by AGS. The fitters have been amazing, they were very helpful in selecting and recommending ideas. The surveyor was brilliant, worked everything out perfectly. Could not find a fault if I tried. Everything finished to a high standard. They have totally transformed the House . Flush sash windows in white woodgrain with Heritage sills. Definitely worth the extra money, they look like the original windows that would have been fitted when house was built. If everyone had these done the road would look fantastic. So pleased am getting rest of house done. Well done AGS.

Once Andy and Tyler walked through the front door I sensed professionalism. My wife and I talked through what we would like installed, being 5 windows and a new front door, all in uPVC and the windows being sash. Andy explained everything from the window design, a sample, to how best the installation could be done, clarifying with his surveyor on the phone whilst with us. The date for install was set and met and the installation completed in 2 days. The work was brilliant, the mess, non existent. The guys cleaned up as if they'd never been here. Brilliant company and highly recommended

Quality Service from a Professional Family Business
Customer Service
Quality

The replacement UPVC double glazing units for the front and back of our house totalled 11 units, including porch doors, flat and bay windows, and a back door. The work was completed in 5 days by Carl and Jordan, who work well together, and were professional in ensuring a quality job with the minimum of intrusion. They responded rapidly to an unforeseen problem when taking out one of the old windows. From the commencement of our enquiry to the company, we found the responses from Andy Barnett to be concise and prompt, and in the administration department, Ella was knowledgeable and friendly. A well-run and efficient family business, who put service and quality (at a reasonable price) first, and they are worthy of being a Which Trusted Trader. Thank you and well done. We are pleased to recommend Advanced Glazing Systems.

First contact: Phones are answered promptly by polite, efficient, knowledgable members of staff. I found their prices very competitive. The products are good quality. The surveyor and fitter did an excellent job, making good all areas and even vacuuming up the small amount of mess, 1st class.

Fire escape window and Front door

Have now used Advanced Glazing on a few jobs,this job was for a rented property in Upton Park and council wanted us to get bedroom window changed to a fire escape window,as expected from first call to finish I would like to give 10/10 for the professionalism from staff that took the call, the Surveyor and the fitters. I had a call from the tenants once the work was done to say how pleased they were with the work and were so surprised with the tidiness of the fitters,they left the property spotless and were so polite.Would not use anyone else as even the after sales is absolutely fantastic.
