OUR BRAND 

OPTiMAL by L+L Installations Ltd 

At L+L we believe in what we do from start to finish. 
 
We are very proud to offer our own range of L+L uPVC Windows & Doors created under the in-house brand name of OPTiMAL. A name derived from extensive research into the very best parts that can be sourced to create a unique product built to its 'Optimum'  
 
From the base uPVC profile, through to the glazing & ironmongery, even the screws used to put it all together! 
 
Why choose a cheap handle or a cheap locking system knowing it will likely fail within a few years? Something that our FREE Annual Inspection would soon highlite! 
We give you a comprehensive 10-year insurance-backed guarantee and want to ensure the long life of our quality products way beyond. 
 
So to us it's more than creating a cheap window or door to get a sale. 
 
No gimmicks, just quality products done well.
