Home Extensions

At Southeast Windows Ltd, we transform your home with exceptional extension services. Since our founding in 1999, we have been committed to delivering quality single-storey extensions from concept to completion. Whether you want to add a kitchen, dining area, Bathroom, wetroom, or tranquil space for relaxation, our extensions will expand your home’s size and elevate its visual appeal. The picture shows a Double Edwardian roof in Anthracite Grey with anti-solar glare, Blue tint self-cleaning glass, and a 4-pane Bi-Folding door with a Traffic door on the left for entry and exit, all installed by our skilled general builders with minimum disruption for the homeowners.

Customised Solutions

We begin our service with a FREE site survey to discuss your requirements and tailor our solutions to your needs. Our 3D CAD software allows us to design your Extension or Conservatory with millimeter-perfect precision. You can customise every detail, from window and door placements to brickwork colours, and add features like Patio and Bi-Fold Doors, glass roofs, and solid roofs with Velux-style roof lights. This customisation empowers you to create the perfect space, delivered and installed to your specifications and personal requirements and installed by our general builders.

Base Options

We offer two base options that meet the latest building regulations:

Traditional Build: This method involves digging a 600mm wide by 1-meter deep trench filled with C25 concrete, requiring significant excavation by general builders with many tons of waste to be skipped.
DurabasePlus Steel Base: A modern alternative that speeds up groundwork while reducing on-site waste and mess. It meets all building regulation requirements and can be ready in one day, eliminating the need for skilled tradespeople. This option also provides better U-Values 0.18 than traditional building methods and comes with the manufacturer’s 25-year guarantee.

Durabase Conservatory Solutions

DurabasePlus 100 offers a versatile solution for Extensions, Conservatories, and Porches. This system provides a quicker, cleaner, and more cost-effective alternative to traditional building techniques. It delivers superior U-Values, reduces internal space loss, and is ideal for single-height Extensions. If you’re dealing with subsidence or failed foundations, DurabasePlus 100 offers a dependable solution implemented by our experienced general builders. Being BBA-approved, this product will not fail you.

Porches

Enhance your home’s security and energy efficiency with a new porch from Southeast Windows Ltd. We build and install porches that provide an extra layer of security at your front door while insulating your home’s entrance with double-glazed windows. From building the base to matching your existing brickwork and fitting A+ energy-rated windows, we offer a complete service with various roof styles and tiles to ensure a perfect match for your home. Our expert general builders handle every aspect seamlessly.

Conservatories

We supply and install many Conservatories styles, including Double Edwardian, Edwardian hipped roof, Victorian, Lean-to, P-shaped, T-shaped, Gable-fronted, and Orangery styles. Our Wendland Ultraframe roofing system comes with BBA certification for quality, and we also offer Durabase Conservatory bases that are quicker and cleaner to install than traditional methods, thanks to our experienced general builders.

Planning and Compliance

Our team ensures that all projects adhere to the most recent building regulations. For projects under 30m² that fall under ‘permitted development rights,’ we handle the regulations to ensure thermal separation from the main dwelling and compliance with energy efficiency standards. We care for these details, ensuring our general builders construct your project to the highest standards.

Roy and team did an excellent and professional job replacing 3 front windows, making the change unnoticeable from the outside. They were worked with challenges getting large frames into the upstairs room and were courteous throughout. Would recommend.

Roy and his team fitted new windows and French doors in our house earlier this year (we wanted to live with them for a while before reviewing!). We are really pleased with the quality of the windows and the service from Roy. He's a real gent to deal with and is punctual and professional. His quote wasn't actually the lowest but he was the only one to supply full details of materials, give fire safety and security advice, send a detailed quote etc. Thank you Roy

I got quotes from a few companies however Peter was the only one who followed up to my questions on email so I decided to go with Southeast Windows. I am super glad I did, as Peter was professional and I am really happy with the work done in installing a new PVC backdoor and replacing glass in several windows. Peter was knowledgable, friendly and didn't take advantage of my lack of knowledge of window and door installation like some other builders have, being a first time home owner.I wouldn't hesitate to recommend Peter and Southeast Windows, I will for sure be using them again if I need. Thank you Peter!
