About us

ADH Building Services was established in 1992 and has built a sterling reputation for quality with clients such as Northern Electric, R.N.L.I and the local Council meaning ADH are able to provide great references.

The very nature of ADH’s clients means that quality and service are paramount to its success and doing a sub-standard job is not an option.

With each job we undertake, our aim is to ensure that we meet and surpass expectations, not an easy thing to do within the building trade. Our aim is to complete all projects to the highest standard, so if any issues do occur, we fix them!

We can write lots of information to really try to put across how good we are however, at the end of the day, we have always found people buy from people. The building game has a bad reputation so finding the right company to serve your needs is a nightmare.

So really, the easiest thing to do is pick up the phone, have a chat, see how knowledgeable we are and if you like what you hear, let’s go into more detail together. Please, do not ask for a quote over the phone, we really cannot provide one. That is not us being awkward, it is simply each job is different.

We do a variety of jobs both within domestic, commercial and industrial profiles, always providing the highest quality at the right price!

We do not do the cheap; we offer high-quality at competitive rates – there is an old adage ‘Buy cheap buy twice‘ – we do it right first time! Guaranteed!

Our professionalism is key to our success, our clients come to us as they are looking for quality and want experts not cowboys.
