Excellent: replace complete central heating and underfloor heating distributor, including internal cleaning and revised technical design (see reference on dtnl.nl). Up-to-date professional knowledge, perfectionist and yet practical. Fast and reliable: immediately got us out of the fire and sacrificed his planned day off. Price / quality is fine and no hassle about additional work. Vincent, thanks again!Lees meer

Through an acquaintance with the contact details of DTNL came to have a check if we could replace the central heating boiler for a variant with solar water heater. We already had some ideas about it ourselves. DTNL has helped us perfectly! Unlike the other installers, they did take all the time for us. Everything neatly assembled and no mess left behind. I have experienced things differently.So very satisfied.DTNL thanks for the top service!Lees meer

Vanaf het eerste contact tot en met de oplevering van de werkzaamheden bleek de klantgerichtheid van DTNL. Vakkundig overziet DTNL alle facetten van het onderhoud aan het dak. DTNL is bouwtechnisch degelijk en innovatief en werkt milieubewust. De opdracht aan DTNL was om het platte dak van ons huis uit de jaren 70 onderhoudsarm, toekomstbestendig en duurzaam te renoveren, isoleren en te voorzien van zonnepanelen. Met groot vakmanschap heeft DTNL deze omvangrijke klus glansrijk geklaard. Als particuliere opdrachtgever zijn we uitermate tevreden met het eindresultaat en met de wijze waarop de werkzaamheden zijn uitgevoerd.Lees meer
