Stress Free uPVC Sliding Sash Windows

If you live in a property that still has its original sash windows, you’re likely burdened with an excessive maintenance requirement. Outdated windows in this style often regularly need repainting, re-varnishing and moving components are always needing to be oiled and greased.

By renovating and upgrading with our uPVC sliding sash windows, these become problems of the past. Our uPVC is fully weatherproof and fade proof, meaning they perform come rain or shine. You should only ever need to give them an occasional wipe down to ensure dust or debris doesn’t build up. As a result, your time will be yours to enjoy. Add secondary glazing to older windows to benefit from all of the modern thermally efficient features while maintaining the classic style of your Northampton home.

Fully Bespoke Sash Windows

At T&K, we only install made to measure windows. We believe you should never be settling or compromising, and you get the perfect windows for your home. Whatever Roseview model that may be, you’ll gain full control over a whole host of customisation elements.

From the size to the style and finish of the accessories, you’ll create windows that are tailor made to your Northamptonshire home. We have a full portfolio of coloured foils and can additionally offer authentic woodgrains.

Energy Efficient Windows for Toasty Homes

Fluctuating temperatures can be a frustrating experience in the UK, with our winters being freezing while our summers are often boiling. With our uPVC sliding sash windows, you’ll enjoy a more thermally efficient property, keeping a consistently comfortably cosy house no matter the season.

While our naturally insulative uPVC windows keep your home at a consistent temperature throughout the year, you’ll also see more benefits. Relying less on heating thanks to our windows, your home could become as cost effective as it is comfortable.

unique selling points of sash windows in Northampton

Vertical Sliding Mechanism

Our sash windows open in an upwards motion, rather than opening outwards as a conventional casement would.


Modern Glazed Units

Unlike the sash windows of old, the systems we install are fitted with thermally retentive and durable glass as standard.


Authentic Details

To achieve authentic period aesthetics, our sash windows can come with run thru horns, astragal bars and much more.


Discrete Hardware

The secure locks and modern hardware of these windows are obscured from view, to not affect the overall visual appeal.


Easy to Maintain Design

By using quality locking systems and robust materials, our windows are durable and keep you protected. They’re also easy to keep looking their best, removing potential hassle.


Weatherproof Measures

Weatherseals and additional weather protection engineering ensures you’re never troubled by damp, rotting or leaking.

Double Glazing Reviews T&K


Happy Customers

We were more than happy with all aspects of our conservatory installation, right from Shaun the salesman to the guys on the final visit. All the work went through like clockwork, and we were very happy with the end result. Everyone was so helpful and friendly.
Keith Green
The only time we did not use T&K (it was for two windows and one door) we were so disappointed in the products, we had them taken out and replaced by T&K. All our windows and doors have now been done twice by T&K, and we would never even look at anyone else.
Elizabeth Pridmore
We have used T&K for a new door and complete window installation. From the survey stage, receiving a quotation and final installation, the processes were all straight forward and of course we are more than pleased with the quality of the product and just as important the workmanship and politeness of the fitters. Would not hesitate to recommend T&K to family and friends.
Paul Curtis
My wife and I had windows installed some 15 years ago from T&K and they look as good today as when they were first installed, so much so that we recently had our front, back and two French doors installed. We could not be happier with the results.
Richard Simmons
The T&K team were amazing from start to finish. Professional and punctual from the moment of engagement, quotation, surveying, installation and post-installation service. Extremely friendly and high quality team and our windows and doors were definitely worth the investment. Thanks for your efforts. We wouldn’t hesitate to recommend T&K!
Rachel Phillips
I have used T&K on three separate properties now and they have been great. Cost and product as well as installation as promised. Better still your energy cost nose dive in the winter. Highly recommend!
Philippa Sharp
I am so pleased with our recent installation from T&K that I felt compelled to leave this review. Shaun was respectful and patient in dealing with our request and everything that he promised T&K delivered. We received quotes from four other companies, and I am so happy we chose to go with T&K.
Paul-David Symeou
T&K installed a new door for us the whole service has been outstanding from the visit to the showroom to the day of the installation. All members of the team outstanding could not have asked for more. Highly recommend this company.
Steve Raher
Everyone from the initial sales consultant Steve, to the surveyor, builders, plumbers, electrician, planners and installers were exceptionally professional. I would definitely recommend T&K home improvements to family and friends.
Jonathan Lingard
