Ordered a conservatory, which was promptly installed to a good standard. However, a couple of months on from their last visit, I'm still waiting on a single small windowsill board. Quick to push for payment, extremely slow with the finishing touches, customer service needs some real improvement.

I ordered a front door from this company and I was really happy with the salesman and the installers. Unfortunately the door was damaged so it needed replacing. Again I was really happy with the service and no trouble getting the door replaced. I'm not happy however with the installers of the new door. They left blue sticky pads around the decoration on the door with their explanation that I could try to get it off myself!
Also when they left one of the hinges fell off as soon as I closed the door! I called them back but it wasn't until my husband came home and spoke to them that they cleaned up the door and got rid of the blue sticky pads! Also I'm waiting for the knocker to be fitted 2 weeks later. A call to the showroom has told me that the knocker was there straight away so why am I waiting 2 weeks for it to be fitted? Again the salesman has been helpful but I feel the after service this second time hasn't been good.

Absolutely first class service. I cannot recommend FIS enough. I had a large window replaced for 2 smaller ones, a window cut out, replaced with bifold doors and also 2 bathroom windows replaced. All work was carried out by the fitters (Stacy and Ben). As a tradesman, I have to say their workmanship and attention to detail is on point. Friendly service, advice and no pushy sales techniques. I look forward to the replacement of the front and back doors next month.
Once again I'd like to thank Pasquale and the whole team at FIS for a first class service. **UPDATE** Follow on from my last review. my front and back door which included a window was replaced last week. Following my previous experience with FIS I expected nothing less than an exceptional service and this was certainly delivered by Pas and the team. Aaron done a very professional job with attention to detail. Really pleased with the result. Once again another faultless job carried out by FIS. Massive thank you to Pas and the team!
