    Great to find a local company deliver a first class service. From the initial design, Mark guided me through alternatives which helped enormously due to his knowledge. The fitting team are a credit to the company as they installed the door with a minimum of fuss, were polite and left everything spotless. Thoroughly recommend Lighthouse Windows.

We understand customers want an outstanding service, an efficient product and all at a competitive price.  Lighthouse can offer you exactly that going the extra mile for all our customers.  With over 25 years of experience in the Double Glazing Industry we are passionate about delivering high quality uPVC and Aluminium products.  Lighthouse can also carry out building services covering Conservatory and Porch bases, Loft Conversions and House Extensions.  We can transform your conservatory into a usable space 365 days a year by adding a Supalite Roof.  This innovative product is fast growing in popularity and is the perfect solution to the draughty tired conservatory.  It will breathe a whole new lease of life into your home.  We have a professional carpenter that will be able to cater for all your internal an external work.  His extensive knowledge of the carpentry and uPVC industry makes him a great all round tradesman.  All our tradesmen are qualified, polite, professional and reliable.  Our fitters hold a CSCS card which provides reassurance that health an safety practises are met.  They are a fine example of our work ethos.  


Lighthouse can also dress your windows with style by adding super stylish Shutters.  We specialise in this product which enables us to provide the best design advice as the product is bespoke to your window profile.  Lighthouse offers this luxurious product without the price tag because we are customer driven and happy customers are a genuine advert for what we do.  Shutters are available in a variety of materials and colours and we can assist with you making the right choices.  They are the perfect solution for your window covering, filtering light and providing you with privacy.  They are suitable to all property types because there are so many styles available.  Everyone notices a house with Shutters ! For all of those windows not suitable for shutters, why not consider the integral blind system.  This is a blind concealed within the unit of the glass, they will never need cleaning and are simple to use, either by pull chord or magnet system.  The existing unit of glass is replaced by a new piece featuring the blind and these can be produced and fitted within weeks.  These are perfect for areas such as French doors, well worth a comparative price.  


All our window/door/conservatory installations are covered with a ten year insurance backed Guarantee and Registered with FENSA where required.  



As a company Lighthouse are very conscious of the environment, and with this in mind, in accordance with the BFRC scheme, we offer A+14 rated energy efficient windows as standard.  These are exclusive to us as a company in the area and no other competitor can provide you with he same rating.  Poorly selected windows are a major source of heat loss in the winter but choosing an energy efficient window, it will help to minimise the cost of heating your home in the colder months of the year.
