There are not enough superlatives to describe how delighted I have been from start to finish in the work carried out by Promas and in all my dealings with them. They are in a league of their own as far as professionalism and integrity is concerned. Their standards are of the very highest and their work is exceptional. Andy leads by example and has treated our project as if it were on his own home. We have had many challenges which have been the legacy of previous inferior workmen. But Andy’s team have displayed huge commitment, resourcefulness, initiative and skill. They have turned a disaster zone into an outdoor leisure place of functionality and beauty. And all in record time and with complete attention to details and workmanship. I cannot recommend this company highly enough and would happily answer any questions if you need further clarification on any aspect of their work. They could not be beaten but don’t tell everyone as I won’t be using anyone else for future work so need them to have time to fit me in!

As an investor in real estate I had chosen Promas as the main contractor for a big renovation project of a Villa in Elviria and I am very happy to have made that decision. Andy and his team are really professionals. You can clearly see that Andy is fully involved in the project, has loads of experience and passing by almost every day to make sure all is going according to plan. Aside that, which I think within construction is unique, he never told me no or that’s not possible or no we can’t change the plans. Instead each time I requested a change of plans we easily found solutions to make it happen. So Promas thinks in your benefit, not in theirs. Finally and probably most important is that Promas finish the project completely, instead of running to the next project and leaving with some loose ends. So if you are looking for a construction company I can assure you that you won’t regret choosing for Promas. Thanks again Andy and the team!

So impressed with the service and quality of workmanship from Andy and his team at Promas. I got various quotes for the construction work at my villa near Marbella but by far away Andy was the most professional. Very pleased with the result of the work and I would happily recommend them to anyone on the coast.

We had the pleasure of using Promas Construction to totally remodel our 3 bedroom and 3 bathroom apartment in Reserva Alcuzcuz. We found Andy Promas and his team to be excellent and responsive. We set them a tight timetable for the work it was vitally important to us that they delivered, both on time and on budget. They passed this fundamental test with flying colours We were always kept informed of progress via a weekly video which was very reassuring. Andy really cares about his clients and his reputation. He deserves to be highly respected amongst his peers! The end result is excellent and much envied by friends and neighbours.

Promas building provided an absolutely outstanding service from beginning to end. The communication was exceptional throughout the project and they were responsive to changes in the planning and execution of the work. All design, building, electrical, plumbing and tiling work was done on time and to a high standard and I am delighted with the results. Most importantly, they seem to have a genuine passion for what they do and go to quite extraordinary lengths to ensure they exceed the clients expectations. I could not recommend them highly enough.
