What We Do

If your home is bursting at the seams but the idea of moving elsewhere is less than appetising, why not consider a home extension?


From new tiles on the wall to a brand new suite with a power shower, you’ll be amazed at what a difference one call to K J East Ltd can make.


Garage and loft conversions are a savvy investment which make use of existing space, giving you a more useful room that you can turn into anything you like.


Should you be lucky enough to own a property with plenty of land, you might even have your own barn too, but are you using it to its full potential?

Fantastic company, literally pulled us out of a horrible situation just before Christmas. We had a new kitchen fitted and unfortunately employed cowboys. KJ East then came to the rescue just before Xmas and completely refitted the kitchen, repaired the damage and put everything right. Super professional, well priced and very reliable.

We needed an old conservatory dismantled which had been erected on a raised platform and needed ideas of what would be an ideal replacement. On completion the work done by Kevin and his team was excellent and very professional. I would not hesitate to recommend K.J. East Building Services.

Professional polite family team, first class workmanship and very clean and tidy. Highly recommended, will be using again in the future. Thank you for your hard work this week.
