LONDON HIU ENGINEERS

Highly recommend this firm.

— James O, from Poplar East London – E14. ( 25th of May. )
Excellent service from the first point of contact. Very flexible when I wanted to change dates which they accommodated as I had a fairly urgent problem. The workmanship was excellent as was the follow up visit to fit the new parts needed to repair my HIU. The job was completed quickly with the minimum of fuss and no mess. Highly recommend this firm.

Very reasonable price and extremely pleased with the work done!

— J Gordon from Canary Wharf, East London – E14. ( 2nd of June )
Excellent admin/organisation and the engineer was punctual, thorough and efficient. Very reasonable price and extremely pleased with the work done!

I would gladly recommend them.

— Johan Harmse from Canning Town, East London – E16. ( 9th of June )

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.

ADD detail hung 8 doors in my house, they were efficient, helpful and left the place immaculate. I had been let down by a builder and had gaping holes and wrecked the door frames. Sigis rebuilt the frames and architrave from scratch and hung all the doors so that they fit, even where the space was uneven. He was flexible and ready to give advice, always on time and cleaned up after each of the days he was here. His work was great value.Highly recommended.

Sigitas and Justin re-did our bathroom, re-modelled elements of the kitchen and did a number of other jobs through the house. They were absolutely excellent- friendly, helpful, left no mess and the work was exceptionally good. Undoubtedly the best experience I've had with builders. I would have absolutely no hesitation in recommending them.
