R.E.G are Reliable, Excellent and Great at what they do!

Mike and his team are incredibly reliable. They came exactly when they said they would and were very respectful.

Neal (who works for Mike) spent around 3 weeks doing up our bathroom. As a young woman I have been patronised in the past and told what I should do when having work done on the house by other companies, but Neal made sure he did what I wanted at all times and made it an easy process for me. He was also very tidy and cleaned up after every work day and took pride in his work.

Our toilet was faulty and leaking soon after being installed and Mike who owns R.E.G was easy to get hold of and sent his plumbers around immediately to sort it out.

I have long list of other things that need doing in the house I will definitely use R.E.G Construction again!

Highly recommended!

Excellent service from REG and his ‘boys’ from day one. He estimated the renovation would be 5/6 weeks and that is what it was. The price he quoted was stuck to too. They created a downstairs cloakroom, put a lantern light in my lounge, took a chimney out of my kitchen, demolished the old units and fitted the new ones. We are really pleased with the finished job. Everyone of the trades involved worked seamlessly and to a high standard. Extras I asked for on the job were done without question and every day they cleaned up after themselves, leaving their work space spotless at the end of each night and they started each day promptly. Highly recommended!

Complete renovation of 6 bedroom detached in Cyncoed, Cardiff

Mike and his team are by a distance the best building company we have used over my 30 year career renovating houses.
Mike has extensive experience of all types of building and his views and suggestions were invaluable in achieving our goals in our latest project as he has a good sense of design. This helped in avoiding several potential mistakes in the overall look of the house.
His team are all genuinely skilled, pleasant, considerate and tidy guys with years of experience and their views were very useful too. Be good to them and they will return the favour.
Mike also has a range of contacts several of which we employed to do specialist work such as our glass panelled staircase.
REG construction owned and run by Mike are an exceptional outfit and his charges are very fair for the outstanding quality of the work done!
Should we go on to another renovation or need any more work doing in the future REG will be our choice on builder.
