“No hesitation in recommending”
The engineers from Hollis Plumbing and Gas were both excellent. The work was carried out efficiently and extremely thoroughly. I would have no hesitation in recommending them - and in fact have booked them to return to do another job later in the month.
“The absolute best”
Hollis Plumbing are the absolute best. Super efficient, professional, courteous, and reasonably priced. We’ve used them for 2 new boiler installations, re-plumbing a new kitchen, moving radiators, and routine maintenance and boiler services. Every visit has been top-notch and a pleasure to deal with the team. Highly recommend for anyone in the Cardiff and surrounding area needing reliable, friendly plumbing services!
