We have a no pressure approach to meeting our customers and we always send written quotations following a visit. We understand that these projects sometimes take a while to get off the ground and we know that our customers don't want to be hassled so we simply send the quotation and wait. Some customers come back within a week, others take a month or even a year and that's fine.

Below you'll find a selection of work we have undertaken in the Durham area, supplying and fitting timber windows.





Heritage Sash Windows on the Pennines in County Durham

This imposing former Vicarage, situated in an exposed location close to Barnard Castle and Durham was very cold in winter - the result of single glazing and draughty old sash windows. It was essential to retain the Victorian charm of the house from outside and inside so we replaced the windows with double-glazed Heritage Sash windows.

This window has narrower double-glazing so that it is much harder to spot that it has two panes of glass.

As part of the installation, we had to remove and replace the existing, fully functioning timber shutters in several of the rooms. Once back in-place the new timber sash windows look identical to the original Victorian ones.




Timber Sash Windows in County Durham

This house occupies a commanding position atop a hill along the route of the old Roman road Dere Street, half-way between Durham and Hexham and close to Bishop Auckland.

The new owners of the house wanted a lighter, fresher look to the house and as part of the process, had decided to change the windows. What they had were dark-stained, hardwood casement windows, top-hung over fixed lights and they did nothing for the appearance of the property.

It was clear from looking at them that the original window reveals had been built for sliding sash windows and so that is what we put back in. The best option in this case was our Slimline Sash window as these offered the greatest width of glass and so would let in more natural light.

Rather than opt for white windows in a white-rendered house, our clients made the inspired choice of having us factory-paint the windows in Little Green Paint Co.'s Limestone 238. As you can see, this gives just enough colour without losing any of the fresh and bright appearance of the house.

These timber sash windows can be supplied in either engineered Redwood or hardwood and fully-finished in any colour or even different colours outside and inside.




Sliding Sash Windows, Durham

This installation demonstrates how well modern, energy-efficient, weather-proof timber windows can blend in with an old property. This house in Durham must date back to the early 19th Century but the new windows look totally in-keeping. We chose a colour to complement the yellowy mortar between the bricks and designed the windows with small panes which would have been typical of the period that the house was built in.




Beautiful Oriel Bay Window

This window is in a house north of Durham and was part of a much larger window replacement project.

The glass is all square-leaded which adds to the old-style of the window. The two end-windows open whilst the two centre-windows are fitted with fixed- or dummy-sashes to give the window a balanced and even appearance.




Cottage-Style Casement Windows In Durham

More warm summer sun, this time in Durham, to show off our timber casement windows designed with narrow timber glazing bars dividing the fairly large sashes into smaller panes. We have fitted fixed sashes (also called dummy sashes) into all non-opening lights in order to maintain nice even sight-lines across the width of the windows. In the bedroom, egress hinges will allow the sashes to be opened widely for ease of egress in the unlikely event of a fire downstairs.




High-specification Stormproof Casements In County Durham

Balance and harmony were the requirements here for a barn conversion around 3-sides of a courtyard near Durham. The existing windows offered poor insulation but allowed plenty of light into the rooms and this feature had to be retained. We were able to line all of the sight-lines through despite the mix of transoms and mid-rails plus fixed and opening sashes.

All of the opening sashes have high security locking and stainless steel friction stay hinges, the doors have fully adjustable security hinges and a German-made security locking system. Adding the finishing touches were the hand-forged door handles in Gothic style plus locking black 'peardrop' handles. To maximise the thermal insulation we opted for low-emissivity glass with argon gas and black warm-edge spacer bar.




Barn Conversion Windows and Doors

A beautiful early spring day shows off one of our recent installations of stormproof casement windows, glazed screens, French doors and a front entrance door into a barn conversion on the edge of Durham.

This building was derelict when our customers bought it but they have transformed it into a beautiful family home. One of the special features here was the tall glazed screen set behind one of the original timber lintels throwing masses of natural light into the open-plan kitchen and dining area. Engineered redwood timber was used for stability and durability and all of these timber windows and doors were finished in Ivory.

The timber composite entrance door provides high security and excellent insulation for the hallway.




Mock Sash Double Glazed Timber Windows

Mock sash windows are a great option for those who want the look of a sash timber window but would like to be able to clean the windows from inside.

This is an installation we recently completed near Darlington. In this case the Mock Sash timber windows are built from the same timber sections as our traditional sash timber windows.

These Mock Sash timber windows are frequently selected for upper floors to complement traditional sash timber windows on the ground floor, and there is also a fire-escape version of this window which opens wide enough to allow emergency egress should the need arise.

Alternatively, where there is limited room for a deep window, these Mock Sash Casements are a good alternative.

Blackthorn Timber Windows supply and install quality timber windows throughout the North of England and beyond.
