We are known for our high-quality, double glazed windows, doors and conservatories and exceptional customer service. We’re a highly recommended Bexhill-on-Sea double glazing company, scoring an amazing 10 out of 10 on checkatrade.

If you are looking to have new windows installed or doors to your beautiful Bexhill home, then look no further. We can supply and install any style of PVCu window to suit your property, including casement, tilt and turn, sliding sash and flush sash. We also use the same trusted manufacturer for all of our windows. This ensures a perfect colour match every time.
There are so many double glazing options to choose from, which is why we offer free design advice on our window installation service as well as to our Bexhill uPVC door installation customers. We will use our many years of experience to advise on which style would best suit your home. This might include single and double doors, composite, bi-fold or patio doors, or even a new porch.
We also provide high quality conservatory installation throughout Bexhill, East Sussex. Our service is consistent, from design to installation, and our prices are competitive. Having a conservatory added onto your home will increase the value of your Bexhill-on-Sea property. It will also give you valuable extra living space to enjoy.
If you already have an existing glass roof conservatory, we can provide a replacement conservatory roof, so that your conservatory can be enjoyed all year long. Living by the sea can bring hot summers and chilly winters – we’ll help your conservatory with improved insulation. This will help to keep it cool in the summer and warm in the winter. So many houses throughout Bexhill and East Sussex have already benefitted from having their conservatory roof replaced by us!
There are many double glazed conservatory style options available. As such, we will be happy to discuss these with you fully to ensure that you make an informed choice that is just perfect for your requirements and treasured Bexhill home.
In addition to our double glazing services, we can also replace the roofline of your Bexhill home with low maintenance PVCu roofline products. For example, fascias, soffits and guttering. This can be a very cost-effective way of enhancing the overall appearance and value of your property.


Great company! Fitted us in very quickly as we were on a tight turn around on this project. Reasonable price, tidy, professional, reliable… what more can I say or expect. Really friendly team and easy to deal with.

Turned up on time and did a fabulous job. Left the house just as they found it and the wife was so happy, it looks like the front door is next. Would have no issues in recommending to anyone. Thank you.

From placing our order to fitting we were kept informed. The windows look amazing and really well finished off ! Andy and his son left no mess, , even hoovered and cleaned the windows . Would strongly recommend! Thank you
