Composite doors

uPVC fascias and soffits

Your fascias and soffits are integral components of your property, keeping your roof space ventilated, supporting the guttering and bottom row of roof tiles, and in turn keeping damp at bay.


Unfortunately, your old timber fascias and soffits will need regular maintenance to stay in good condition - something that probably hasn't happened too often given their inaccessibility!


Our uPVC replacements will last the test of time, requiring no painting or maintenance and remaining weatherproof and rot resistant throughout their lifespan.

Window repair

Did you know we can repair many of the problems commonly associated with windows without the need for ripping out and replacing the entire unit?


To enquire about our replacement sealed units, lock repairs and other services, just get in touch to let us know what issues you are experiencing. We'll attend your property to assess the problem and give you a quote for the repair work required.

Aluminium windows and doors

Whilst uPVC is still the most popular choice of material among our clients, a growing number of people are opting for aluminium due to its toughness, resilience and sleek, contemporary appearance.


Aluminium is ideal for high-street shops but also makes for great window and doors in residential properties, too!
