As apposed to the very costly solution of hardwood replacement sash windows, we specialise in restoring the existing units, that can relieve the cost by up to 50%, yet give the same quality finish. We take out each casement and strip them back to bare wood, treat any rotten areas of the frame and the casements with the leading timber repair and care methods, rebuilding the units back to their former glory. Before we repaint and refit your sash units we reglaze them with a choice of 4 - 6 mm glass, or 9mm - 11mm double glazing. Finally our draft proofing system is installed - and it actually works!

All of our tradesmen are fully qualified in their own field, these includes NICEIC and Part P approved electricians, Gas Safe (corgi registered) plumbers, NVQ level 3 carpentry and joinery, National Diploma in the built environment.

Our general work is that of new builds, domestic property and public houses, varying from small internal adjustments such as replacing doors, architraves / skirting, laying floors etc to larger projects including extensions, loft conversions, roofing, structural solutions, chimney breast removal and renovations.
