"No pressure salesmanship when I got a quote. Thorough measuring of doors and windows by surveyor. Installation was earlier than estimated date. Friendly and skilled service from installers. They also fitted the cat flap (a non-standard one I supplied on installation day), demonstrated the door locking mechanisms and cleaned everything up afterwards. Brilliant. SEH BAC have done the replacement windows on my home in stages over the last few years. They have never disappointed me."

"From start to finish I was very impressed. Sales person gave us the price without any sales tricks. Surveyed carried out efficiently and without any problems. Installation of the doors and windows was finished to a high standard, installer even when out to purchase a cat-flap when one was not put on the van rather than leave it to be sorted later. This is the second time I have used SEHBAC and was again very impressed with the whole process. Also every appointment was kept to with no messing the customer around."

"I have used this company several times for front doors, window, porch and French doors. The service and workmanship has always been to the highest standard. The work has been completed quickly and efficiently and I have had no problems. I will definitely use them for future projects."

"We wanted to let you know how pleased we are with our beautiful conservatory. Right from the beginning we had two contacts who were always on hand to answer any question and reassure us. We cannot praise SEHBAC enough and would recommend you to everyone. We were worried about the mess and upheaval, but we can honestly say that your fitters were a pleasure to have on site, everyone was so pleasant and professional in every way. Once again thank you all so much."

“I am absolutely thrilled with the end product, I love my orangery to bits. The whole process has been excellent from start to finish – from the first visit to the showroom, to the designs, to the installation. Everything went so well, there was minimal disruption during construction, not a lot of mess and the team cleared up after themselves every day. I couldn’t be more thrilled by the expertise, craftsmanship and outcome of our orangery project. It’s superb.”
