Our aim is to provide all of our customers with a hassle free experience from start to finish. NO SALES PEOPLE EVER, just honest, reliable advice from people that know the industry!

We offer all of our customers exactly the same services as "the bigger" companies, just with none of the jargon or pressure sales!

Generally less expensive than a traditional extension, a conservatory will give you a light and airy versatile living space. Coupled with high specification energy efficient glass options and the correct heating system, conservatories have become a room you can use and enjoy all year round. Whether you choose a traditional conservatory design, orangery or contemporary glass extension, you can transform the appearance of your home as well as adding to its value and appeal. Here at Cromwell, we oversee every aspect of your conservatory project, from initial consultation through to the electrical installation.

With "Grand Designs" and other such programmes on television, bi-fold or multi-folding doors have become enormously popular in recent years. Our range of aluminium multi-folding doors combine sleek slim line profiles with fantastically aesthetically pleasing hardware. Available in a huge range of colours, they add a real wow factor to any home and allow natural light to flood into a room. They can be designed to give a seamless transition between inside and outside and come in a variety of door opening options.

Our window range is extensive and comes in a limitless variety of colours and designs - including casement, tilt/turn and vertical sliding sash window styles. As well as improving your homes appearance, replacement windows can also make your home warmer, quieter and more secure. Upvc windows have become the most popular choice for replacement windows. Available in almost any colour, they are virtually maintenance free - soapy water and a damp cloth for cleaning is all they need regualy, they do not split, rot or warp like timber and will never need painting!

Our range of Solidor composite front doors is vast. It includes many of the traditional door designs as well as offering many more contemporary designs. Available in 17 colour options, from standard white through to aubergine and with an extensive range of glazing and furniture options, coupled with police approved "secured by design" accreditation, there really is a Solidor for every home. Security is always a factor when replacing doors, especially front doors. Unlike most other foam filled composite doors available, the Solidor door has a 48mm solid timber core, making it one of the strongest and secure residential doors available today.

Having received several personal recommendations I am so pleased we chose Cromwell to replace our front door and windows. Mark and his team were fantastic - friendly, extremely knowledgable and carried out the work efficiently without leaving any mess. We've had so many compliments on our new door and I would recommend Mark without hesitation.

I am very happy with my new conservatory. Mark has done an excellent job. I would definitely recommend him to anyone looking for work to be done. Mark is reliable friendly and takes a pride in his work.

We are so pleased that we chose Mark & Cromwell Windows to replace our front door and patio doors. Everything was superb: initial meeting, description of products and how they compare to others. Agreed cost of work/products, without having to haggle - we knew what another local company would charge. Cromwell Windows do not employ any sales people. No pressure, no commissions! Installed and admired by the neighbours as well as us. If anything the new front door looks better than we expected. I cannot imagine why anyone would need to go to another company in the Basingstoke area!
