Doors & Windows Installation

Whether you’re looking for new doors or windows, for internal or external use, Lalco can supply and install these for you – as well as disposing of your old installations.
We offer uPVC windows with a 10-year manufacturer’s guarantee: and these windows are practically maintenance free! The installation of these will eliminate your worries on rust, flaking paper rot and paint peeling.
Our door offerings come in a range of types, shapes and sizes, and our expert team can make recommendations as to what will suit your property best. The choice of doors for your home should not just be made on a colour and appearance basis, but also security and suitability; and we can help you make an informed choice for a great value door purchase.



Conservatories come in many shapes, sizes and types but the design and installation should be done completely bespoke, tailored to suit your property and circumstances as best possible.
Add value and a new living space to your home with a conservatory fitted by Lalco. We’ll make your dream for a new room reality and guide you through the process from idea all the way through to making the finishing touches.
Your new conservatory need not look the same as everyone else’s, nor need it be a part-time living space: we can advise you on a building design that will facilitate warmth during cold weather and cool during warm weather, so you can enjoy year-round room usage!



Don’t fork out for a house extension without considering an orangery. Tailor-made to order, Lalco can help design and build your dream orangery, adding an elegant touch to your property without compromising on space or comfort.
Considerably more cost and time effective than the rigmarole of planning permission and expenditure on a formal expenditure, an orangery can give you fresh space and a touch of luxury. Often more practical than a conservatory, orangeries are multi-functional and easily usable even in the coldest of weather. Originally designed as a way for the wealthy to grow citrus fruits year-round, you may not be looking to harvest a lemon crop, but you may be looking for some extra space – and we can make that happen!


Home entrance doors

Trusted and leading providers of Rockdoors, Lalco install tailor-made composite doors, stable doors and French doors; all with unmatched strength and security.
The market leaders in secure home entrance doors, Rockdoors are made using high-impact uPVC are wrapped in aluminium moulds, giving a realistic wood-effect texture. This gives the appearance of a traditional timber door but with modern security features. The Rockdoor is then reinforced with carbon fibre (which is stronger than steel), and custom glass panelling is sealed in, encapsulating the weakest point entirely – making them no longer the ‘weak spot’ for would-be thieves.
Security doors that don’t look heavy or cumbersome, Lalco can design your door to either fit into your home’s existing aesthetic or to ‘make a statement’. Get in touch to start your design journey!


Panoramic windows

Giving an unrivalled view of the landscape from your property, panoramic windows come in numerous styles and with various functions.
Lalco can help design and install your panoramic windows and can include parallel opening, tilt turn or windows in a casement.
It’s often assumed that panoramic windows are only appropriate for penthouse apartments or luxury beach houses, but this truly isn’t the case – and we can help advise you and find a suitable panoramic window no matter the size or space that you’re dealing with for your own property. Panoramic windows also need not compromise on weather-resistance, noise reduction or thermal insulation, and we will only recommend and install windows that we believe to be appropriate and comfortable for you.


Sliding/bifold doors

Both sliding and bifold doors can have a spectacular impact on your home, but it’s important to understand the difference between them before you make a purchase.
Sliding doors slide horizontally across and fits either between, in front or behind a panel of glass. These are commonly used as patio doors and entrances to conservatories and orangeries. They’re great for big spaces and can be fitted easily in a range of different styles and colours.
If you’re pressed for space, bifold doors may be a better option. Bifold doors fold back on themselves to take up less room at one end of the door, neatly stacked in a concertina. If looking for a door that leads to the outside, bifold doors are also ideal as they can include a ‘traffic door’ allowing access without having to open everything up.
We can help advise and install the perfect sliding or bifold doors for you.
