Masterframe Trade Logo

Whether you’re a builder tendering for a contract, an installer looking to replace windows for an end user or simply needing a budget price, our team is here,  knowledgeable and ready to help. Most end users expect high quality goods, ones which look like wood in every detail, they could just do without any of the painting!

Unlike casement land where price is the only thing that matters, people buying sash windows take pride in their homes and they’re prepared to invest a little extra, especially once you’ve explained the benefits and resons why the cost is a little higher.

That’s where our sales team is here to help you.

Right now you have technical experts on hand to answer your questions and a wealth of documents to help your customer understand the benefits of a Masterframe sash window.

We will get back to you as soon as posible on any queries you may have. Please fill out the form and we will give you a call.


Richard is your contact for commercial projects and technical queries. He is available for one on one meetings nationwide.

Carol Slade

As Managing Director, Carol can help close deals so if you have a special project that needs a little assistance, please  speak to the sales team who will  refer your enquiry to her.

Leave the M25 at junction 28, onto the A12 towards Colchester. Bypass all Chelmsford signs, and go past Hatfield Peverel.

Take the second exit from the A12, sign-posted Witham Industry. (If you do take the first exit, just head straight through the town centre, past the police station, and turn left into Crittal road before the petrol station).

Go straight over the traffic lights and straight across the mini roundabout. There is a petrol station on your right, then take the first right hand turning into Crittall Road. We are the first building on the right and have a visitors parking space waiting for you.


Come off the M11 southbound at the Stansted turning, then join the A120 heading towards Braintree (the fourth exit), then second left at the next roundabout heading towards Witham. Go through Cressing village and approximately five miles on you will enter Witham.

Head towards the town centre, i.e. right at the first mini roundabout, straight over the second, right on the third, and left at the fourth, just before the mainline station.

Once over the railway bridge with the station on your left, turn left at the mini roundabout into The Avenue and left at the traffic lights heading out of Witham towards the A12. Crittall Road will be on your left. Masterframe is the first building on the right once in Crittall Road.


Witham is a main line station approximately 50 mins away from Liverpool Street. On arrival please phone so we can collect you, or take a short journey by taxi at a nominal fee.
