Installation - by end user

This is an easy to assemble product which has been designed to be installed rapidly on site by two people. It is very important that the curb onto which it is being installed is fully sealed by a competent builder or roofing contractor. 

Its is very important to consider all on-site health and safety considerations before installing this product. With special consideration given to avoiding falling through the rooflight during installation.

The rooflight itself is designed to be watertight without the use of silicone seals. However, a silicone seal will be required to ‘bed’ the rooflight down onto the pre-installed upstand on the roof.

The simple to follow step by step installation instruction document can be found here - which if followed should enable any competent person to install this product safely and effectively. 

We recommend that this video should be watched in conjunction with the installation instruction document as it shown clearly how these component parts fit together in the correct order.

If you require installation by Finesse Windows Ltd please contact us directly for further information.

We were looking for a local company to replace our kitchen window. We visited Finesse and spoke with Bob Tooth. Told him what we wanted and he showed us an example of the product, which we very much liked. We were concerned that because we only wanted one window replaced that big companies wouldn’t want the work, or would quote silly prices. However, the price quoted was much cheaper than I expected so we agreed to them doing the work. Everything ran very smoothly there after. Bob came out and checked my measurements and then we received a visit from the surveyor. We were kept informed of progress and the window was fitted on the date specified. The 2 fitters fitted the window and cleared up all their mess. Overall we are extremely pleased with the quality of the window and the service provided by Finesse. We would certainly use them again if and when we needed another window replaced

We're really pleased with the lovely new front door Finesse Windows have installed for us. Brilliant, straightforward service, from the initial enquiry through to installation and aftercare. Each member of staff has been very friendly, knowledgeable and professional and communication has been fantastic all the way through. Thank you to the whole team and especially Jamie, Macie, Chris and Lindsey.
