The benefits of Timber alternative or Residence 9 windows for your Merton home

Timber alternative windows present a range of benefits to homeowners looking to improve the aesthetic appeal of their property and its energy efficiency. We can supply and fit Residence 9 timber alternative windows, which are designed to replicate the authenticity of wood with the use of uPVC. Thanks to their subtle design and versatile range of colours and woodgrains effects, they will suit a huge variety of homes, from more traditional period properties, through to contemporary buildings and flats. They are also ideal for people living in conservation areas, where there are certain guidelines regarding styling.

Timber windows are undeniably attractive but can require a lot of maintenance and upkeep. Residence 9 windows are maintenance free, so will never require painting, varnishing or sanding and will always look good. Their thermal performance is outstanding and they can be made to incorporate double or triple glazing. This is kinder on the environment and on your bank balance! For more information about window efficiency, see our blog.

Very impressed with the service provided, from the initial consultation to the final installation, everything was dealt in a very professional way.


Amazing job, I really recommend Unique Windows (London). They fitted the new doors and removed the old ones, left the place looking as it was and this was all done within a week of getting the quote, amazingly fast and reliable service with quality trades people.


We had changed all the windows in the house. They look very smart and elegant. So much that I only had praises from my neighbours and friends. Unique windows did a fantastic job at a very competitive price. Very tidy, quick and efficient. Overall, an excellent customer service. I have already recommended Unique Windows to my neighbours and friends, and I believe they have contact this company already. I will certainly use them again.


Very pleased with our new doors and windows. The fitting is excellent and Unique Windows were able to accommodate a couple of non-standard requests. Price was fair and communication clear. I would use them again in future for the remainder of the windows on our house and recommend.
