Available in custom configurations including leaded lights and Georgian-style units, they suit both contemporary and traditional properties across residential and commercial sectors.

Capable of spanning up to 14 leaves with 3m height capacity, these doors incorporate multi-point locking systems and thermally insulated profiles. Ideal for residential extensions and commercial spaces requiring maximum daylight penetration and accessibility.

Mark and Lee carried out repointing (putty) work on my 60yr-old bay window. Exceptionally skillful work, excellent result.
Punctual, clean and tidy.

I have to say, Lee and his team were amazing. They have done brilliant job on the windows including fixing my door lock and couple of other small jobs. I would not hesitate to recommend and will certainly only go to them for my windows.
