Also, we can upgrade your old existing frames with new moving parts. This can be achieved by fitting more energy efficient slimlite double glazed windows into the new joinery, which perfectly meets the requirements of building regulations, and on top of that, cuts your energy bills.

Double Hang Sash Windows
Our double hang box sash windows are traditionally hand crafted, resourcing the finest wood materials. These beautiful bespoke windows will bring the classic touch to even the most modern of properties. We can match your existing window, and at the same time fit an energy efficient, and environmentally friendly bespoke UPVC box sash window, which are made using softwood or hardwood. Our windows comes with cords, pull handles & weights, traditional ovolo, lambs tongue or contemporary square shaped with natural finish or spray painted. These windows can be single glazed or double glazed, and are fully draught-proofed.

We manufacture and install completely new bespoke timber casement windows of all styles include traditional flush casements, storm proof and modern designs. These can be single or double glazed.
