Bright and Attractive


Our conservatories are one of our most popular products on the Wirral and prove that when they’re done properly they can truly add value to a home. Built to the same exacting standards of our orangeries, your conservatory can be built to your specification from top to bottom.

Choose from dozens of options of sizes, shapes and colours in our conservatory showroom here in Liverpool, or take a look at our gallery for inspiration.

Smartly Built

Replacement Roofs

We can now fit all of our conservatories and orangeries with Celsius solid retrofit roofs. These structured insulated panels are a great way to keep heat locked into your extension and can even be fitted retroactively onto a pre-existing conservatory.

If you’re settled with your current conservatory but would like to make more use of it during the winter months (without spending a fortune on heating each year) then fitting a solid conservatory roof replacement could be just the thing for you. Each and every one we fit is bespoke to the job, so we can allow space to fit downlights or speaker systems into the eaves.

Light and Expansive


Orangeries make for an ideal addition to your home, giving you more room to enjoy your leisure time, whether that’s a new cinema room, play room or dining room – you decide!

We take great pride in all our orangeries, which is why we include a ten year guarantee against cracking, fading and warping. All of our orangeries feature heat reflective, UV-protected Celsius glass, lead-free construction and EasyClean glass technology to make aftercare a cinch. Allerton Windows can also incorporate a series of bifold doors into your build so that you can seamlessly connect your new living space with your garden.

Expand Your Home


Our construction experts have years of experience and have built up a stellar reputation for completing extensions on time and within budget.

We understand that building an extension is a big investment and aim to make the experience as smooth as possible, from drawing up your plans to tidying up after ourselves on the final day.

Strong and Safe


We understand how highly our customers value security, which is why we use double-sealed Liniar profile doors as standard for our replacement jobs. Each door has a wood-like finish and is constructed with resistant UPVC, making it a tough and resilient addition to your home. In addition to being secure, these Liniar doors are also fantastic draught eliminators, saving you even more money in the long run.

We offer a range of quality door brands, besides Liniar, including Rockdoor, Masterdor and Door-Stop. Visit our showroom to take a look at the wide variety of styles, materials and colours that we have to choose from.

Secure and Stylish


Our customers seek three things when it comes to replacing their UPVC windows: longevity, security and insulation. Our bespoke window replacement service on the Wirral offers all three of those qualities, in combination with highly efficient glass, dual compression systems and fusion-welded joints, for guaranteed satisfaction.

We’ve built a winning reputation for being the best double-glazing window suppliers on the Wirral and have the professional work of our employees to thank for that; they’re consistently rated as being tidy and timely by our customers.
