KELRAY Ltd fitted all new windows and doors to our property.  From the first call to reception to dealing with Carl, everyone was so friendly and professional.  The quote was very competitive, the guys who did the work were excellent, they worked quickly, thoroughly and were very professional.  They left everything immaculately clean and tidy and disposed of all old uPVC windows and doors.  I would highly recommend the team for all of your building needs.  A company very worthy of 5 stars.  Thanks everyone.

Dale and his team did a brilliant job and finished the resin flooring to a high standard and on time for project completion.  The project manager was concerned with the resin as he has always had problems with the installation.  However, he is over the moon with the professional, hassle free installation from KELRAY Ltd.

Merthyr Tydfil Housing Association has collaborated with KELRAY Ltd on many projects ranging from reactive repairs, physical adaptations, level access showers to office refurbishments. We have found their work to be of the highest quality coupled with a highly effective and professional approach.  

Their ability to construction project manage in tandem with an honesty has ensured that they have remained on our approved list of contractors for many years. They have a definite management hierarchy which enables us as the client to get in contact with the correct person whenever we need to.

They have an eye for detail, are respectful of our tenants, take pride in what they do and have a realistic view when carrying out valuations and pricing of works and for these reasons we anticipate carrying on with the working relationship well into the future.

We can't thank KELRAY Ltd enough for the amazing work that was completed on our home. They transformed our old house into a new modern home. You couldn't find a more friendly and polite team of boys as well as the office team and of course the boss himself, Carl. Before, during and after the work, the team were always on hand to help. We always praise KELRAY Ltd's work long after moving back and will continue to do so. Thank you so much Kelray.

This was quite a complex restoration project involving a building first built in the 1850's, a large part of which had been closed down for several years due to a lack of repair and maintenance.  No one really knew for certain what KELRAY Ltd would find once restoration work started.  KELRAY Ltd were both friendly and professional to deal with.  They kept to the costs as agreed in the initial Schedule of Works and any additional work that was found to be necessary was first agreed between the Trustees, the Architect and KELARY Ltd prior to the commencement of that work.  There were no hidden costs and the trustees of St.David's Hall were very happy with the quality of the building work and the manner in whichthe  Schedule of Costs were presented to us every month.

"KELRAY Ltd have worked for over ten years in the factory, where I am the facilities manager in an automotive component supplier. I find them very responsive to requests for quotations for building work. With their experience they are able to advise on the best way any type of building or construction work should be carried out. They understand the restraints that projects must be completed within or below budget and on time. They are very professional and their workmanship is to a very high standard. I would have no problems recommending them to anyone."
