If you’re a homeowner in Lewes, you can improve your property in a wide variety of ways. From single- and multi-storey property extensions to home refurbishments and loft conversions, clients rely on our trustworthy team of builders. We pride ourselves on a cost-effective service at every stage but understand that not everyone needs large-scale property renovations. As such, we perform a wide range of other services to give your house in Lewes the care it deserves.

As a professional team of builders with a reputation for cleanliness, quality and safe best practices, Sinclair & Jones Building Contractors Ltd will be delighted to help make your home a more comfortable place. We manage home refurbishments, loft conversions and property extensions with expert scheduling, and take on new builds across Lewes and Sussex.

Do you have questions about a building project? We are always willing to answer your questions and provide guidance on any building or renovation project.


Much like property extensions and home refurbishments and property renovations, the following services will include durable materials to reduce the need for future maintenance.

A Front Porch – A new porch improves the aesthetic beauty of your home’s entranceway to welcoming visitors as they approach. It will increase security, keep the front door dry in poor weather and give you a place to clean your shoes before entering the home. A porch falls under permitted development, so you also won’t need to apply for planning permission. Instead, our in-house team of builders can get straight to work on your Lewes home.

New Windows – Over 90 per cent of houses in the UK have some form of double glazing, but these windows can still break or deteriorate. When considering the types of home refurbishments or property renovations you’d like to pursue, it’s worth looking at ways to improve efficiency for a potential reduction in energy bills. We also fit large windows for property extensions in Lewes and install rooflight windows for bright loft conversions.

A Fresh Driveway – Do you see signs of general wear and tear in your existing driveway? Renew the surface with groundworks and paving from our talented team of builders. Your driveway makes a big first impression, often serving as the first thing that a person will see when visiting your Lewes home. Replacing old materials will make it more visually pleasing, safer to walk on and drain water away from the upper surface.

Patios and Decking – At Sinclair & Jones Building Contractors Ltd, we offer much more than new builds, property extensions, home refurbishments, loft conversions and property renovations. We can also work on your outdoor landscape. More than just a dedicated team of builders, we install raised wooden decking to bring visual interest to the garden and also lay weatherproof patios. This will allow you to enjoy the Lewes summer sun as you see fit.

Underfloor Heating – Although some may consider it pricey to install, underfloor heating is worth the investment because of the long-term savings it can provide. It works at a reduced temperature than most traditional heating systems, making it a great option when planning to refresh your Lewes home with property renovations.
