Sash Window Restoration

For Over 15 Years We Have Been Restoring & Draught Proofing Sash Windows.

Our sash window draught proofing & restoration service is designed to fix the most common problems associated with traditional timber sash windows. Window brush seals are fitted as part of our sash window restoration service that includes an overhaul of the whole box sash frame to bring your old windows back to life. 

Draught proofed sash windows have improved functionality and energy efficiency at a fraction of the cost of replacing your period windows.  

With this service we offer a wide range of high quality furniture that comes in a many different styles and colours


Primarily they seal the gaps where draughts enter, thereby improving the comfort & energy efficiency of your home & saving you money on energy bills. 
Low friction draught seals enable free movement of the sash, yet are tight enough to eliminate intrusive rattles. 
Air borne noise, dust and other pollutants that are suspended within draughts are also greatly reduced.

Replacing broken glass!

Salvaging old glass can be a delicate and time-consuming process, but it does ensure the best heritage conservation standards. At P.T Joinery & Sash Windows we try to salvage as much old glass as possible to ensure we offer the best possible service to give the best authentic looking result.

Putty Pointing.

Linseed putty is the traditional compound used on heritage glazing. When paintwork has been neglected the putty can dry out and crack allowing rain to soak into the wood, creating prime conditions for wet rot to develop. We can replace failed putty but it then needs 7-21 days to form a skin before paint can be applied. Due to this curing time the responsibility to over paint the putty is usually by others. The paint should extend beyond the edge of the putty and onto the glass by 1-2 mm.
