Bathroom Fitting- 16 Jan 2023
Sam did a great job on my new bathroom. He completely removed my old bathroom and made completely new. Sam offered great advice and the bathroom looks great. Whilst removing tiles and plaster board, he discovered I had no lintel installed above the bathroom window. Sam helped organise for a new window and lintels to be installed as per building regulations. Sam was always on time and provided excellent workmanship. I highly recommend.

I'm delighted with the work that Dean and his colleague carried out. The results are of a superior standard - exactly what we'd hoped for - which is testament to how meticulously they worked. They arrived at the expected time and kept going until they had finished the job. They also left the place clean and tidy before leaving which was great. I wouldn't hesitate to recommend DKLA Plumbing and Heating to anyone who asks for similar work and I will absolutely keep this number in my phone book for any future work. Thanks very much Dean and co.
