I was delighted with the service from FIS in advising then providing and fitting a replacement stable door even though several other companies had said it couldn't be done.

Just had 14 windows replaced with FIS. I couldn’t recommend anymore. Very happy, the finishes are immaculate. The fitters were tidy, was like they hadn’t been here.

Would highly recommend FIS windows. Very pleased with overall product - we had secondary double glazing fitted. The fitters were friendly and very experienced. Communication with FIS throughout was good too. Great value.

FIS installed new soffits, fascia's, downpipes and new front door with surrounding windows in a porch at a new property we moved into. Excellent work, quality product and really fantastic people who completed the installation - good knowledge and excellent finish. Highly recommend.

Thank you to all the team at FIS Windows Ltd for their recent installation of windows and doors. My front windows and door were replaced in September and the back windows and door in January and from my initial phone call to the work being completed on both occasions everyone including the office staff, surveyor, the teams behind the scene and the fitters who carried out the installation, were so efficient, helpful, polite and courteous. A credit to the company. I would highly recommend FIS Windows Ltd if you are thinking of replacing your windows and doors.

I would highly recommend FIS Windows Ltd. Their customer service was excellent from the point of walking into their showroom to enquire, to having my new front door fitted. Max was very communicative and helpful and my new front door looks lovely with no more drafts. The price was fair and they booked me in quickly. 10/10!

We always prefer dealing with Small Local Busineses. It was the right Decision. The owner of FIS came around to see what we needed. He priced our two new doors up within 5 days. The Men who installed the Two doors were absolutely Fantastic. They have done a really lovely job and they cleared up behind themselves. They worked all day to get the job done! I will definitely use FIS again!
