What a nightmare! You could be forgiven for thinking removal and refitting of toilet mean they will refit back with no leaks. Not only did they leave me with a leaking bathroom for a week with damage to my walls and ceiling, they then wanted to charge me £150 labour to fix by replacing a valve!! I wish this review gave me the option to add pictures so you can see the extent of the damage and bad job they did. Small positive was that the tiling itself was mostly ok but will NOT use again!

Qualified plumbing, heating and gas engineer - 40 years in the trade and 25 years Gas Safe registered. Full bathroom design and installation. New central heating and boiler installations and upgrades. Also all general building works carried out inside and out. Please contact Mark for a quotation.

We hired Cani Building Services to replace the front stairs and pathway of our Victorian home with granite pavers in the spring of 2025.

Durim offered a competitive quote and promptly started work. ?He completed our job to a high level of quality within a week’s time, and we are very pleased with the outcome. We would absolutely recommend his services to others!

We used Kingz for clearance of a very overgrown garden and new fencing. They did exactly what they said they would do in their quote. They worked hard, left the garden tidy, and took away all the waste. They were very pleasant and Emma, in particular, gave good advice regarding ongoing after care of the garden. We were very happy with the results and would definitely recommend this family team!

This firm sub contracted out the work to a local plumber/carpenter who I found difficult to contact. I needed a new shower as he said he couldn`t repair it. I selected the cheapest one as I am upgrading my bathroom later this year. He couldn`t get it straight away so I selected a dearer one which he fitted. He then told me he was going away the next day. If I hadn`t selected the dearer one I would still be waiting! There is some moisture leaking but I really don`t want him again so I`ll wait and see.

Dean was responsive, helpful and proactive. He came out to attend our leaky bath tap quickly and replaced it. He was also able to fix our water stop tap and a leak on the hot water tank very promptly. As a bonus he was also able to confirm that our boiler did NOT in fact need £3k of work done under warranty as advised by a commercial firm last weekend! All in money well spent & we shall use Dean again without hesitation.

instead of hiring and dealing with multiple people, let us handle the hassle out on your behalf! one deal, one man!
