I Like to use the services of Add Detail, as i find that they are invariably professional, polite and punctual. I needed some work on my radiator, which Justin did. He was on time, and completed the job perfectly. I would definitely recommend Add Detail. We have always been very happy with our experience with Add Detail - Justin is professional, efficient and always completed the work to high standard. Justin has always been able to attend within 24/36 hours which has been particular exceptional.

Great service - super easy to deal with, very straightforward and a high quality workmanship when both repairing an old HIU and when supplying and installing a new one. Many thanks to Justin and Sigis - fantastic!

I'm a landlord of a flat in a relatively new development, which uses shared heating through a system that I don't know much about. HIUs. I tried to use a recommendation that came through the development residents but this person continuously did not give me confidence and also the quote seemed unreasonable. I called HIU and they were transparent with their fees and came when they said they would and did the repart at a fair price. I would highly recommend them. This was back in August 2021 and I've only just got.around to putting this write-up on to here. Good as it means the repair is still fine.

Wow!! Add Detail delivered exceptional service resulting in a very positive experience and total peace of mind. Highly professional, extremely competent and proactive. "Can do attitude" with a smile.

My HIU had been leaking since Christmas and had not been serviced in many years. I was concerned that the HIU wasn't fixable and that a costly replacement HIU was the only option. Justin looked at the leak and fixed it without any fuss. He was also proactive and did extra work and checks to make sure the job was finished to a very high standard. He also took the time to talk about HIU repairs versus replacement even outside office hours. I will be recommending Add Detail to my Estate Management Company so other residents in my building can use them for HIU repairs/replacement/annual service.

We have used Add Detail a number of times over the past couple of years and cannot recommend them highly enough. Most recently they matched a hand-built kitchen unit so we could install a new oven and hob but previously they have refitted our bathroom, built wardrobes and cupboards, laid decking in the garden as well as other smaller house refurbishment jobs. Unlike so many builders they are utterly reliable - a fair quote for the work, they turn up on time, offer clever, constructive suggestions for any problem that occurs, clear up brilliantly after and the workmanship is superb. I have no hesitation in enthusiastically recommending.

Incredibly professional. Justin arrived on time, fixed my leaking loo with no fuss and no mess. Will definitely use them again and recommend them.

Add Detail did a great job of installing our new bathroom, we are very happy. Would highly recommend them.
