Customer's reviews
We recently had our roof fitted and couldn’t be happier with the service. The team showed up on time every day, even in adverse weather conditions, and worked with a level of professionalism that was truly impressive. They were extremely pleasant and easy to deal with throughout the whole process, always keeping us informed and making sure everything was done to the highest standard. The quality of their workmanship speaks for itself, and the whole experience was stress-free from start to finish. Highly recommend this company to anyone looking for reliable, hardworking, and genuinely friendly tradespeople.

I recently hired Diamond property maintenance NI to clean my roof/guttering, and couldn't be more pleased with the results. From start to finish, the process was professional.
I contacted their Facebook page for a quote, and Tristan came out the following day to asses the house/roof. He gave me a quote on the spot and booked me in, with work commencing a few days later. I decided to book with them due to Tristans knowledge. He explained hiw it would not only improve the appearance of the roof but also help prevent further regrowth. Additionally, the reassurance of liability insurance for his team, which I never would have thought of when getting work done at home.
The biocide treatment used removed any build up of moss and made my roof look brand new 😊
Overall, I would highly recommend the team for anyone needing roof cleaning. Thanks again guys!!

I decided that I needed my roof and solar panels cleaned. I contacted four companies, but Diamond rang me and discussed the service and the options available!
I decided to go the whole hog and have the house, garage, solar panels, patio and driveway cleaned! Paid my deposit and agreed a date.
The guys arrived at 8.30 and left at 5pm. They did everything that was agreed and left the place immaculate!
Tristan, one of the bosses turned up and explained the process and the guarantee the company offered!
I certainly recommend Diamond with a full ⭐️⭐️ ⭐️⭐️⭐️
