Will man an der Küste Marbellas ein Haus sanieren oder renovieren, ist man bei Promas  Building an der besten Adresse! Eigentümer Andy hat zusammen mit Ehefrau Katherine ein Unternehmen geschaffen, das seinesgleichen sucht: Vom Keller bis zum Dach, vom Schwimmbad bis zum Garten, von der Beleuchtung bis zum Maler - bei Promas Building wird man kompetent und freundlich beraten und bekommt dank seiner bestens ausgebildeten und freundlichen Mitarbeiter am Ende alles aus einer Hand geliefert. Immer wurden wir, die ja nicht ständig vor Ort waren, via Fotos und Filmen auf dem neuesten Stand bezüglich Baufortschritt gehalten. Nie wurden wir vertröstet, wurde ein Detail vergessen oder der Einzugstermin nach hinten verschoben! Vielen Dank, liebe Andy und Katherine! Euch haben wir ein wunderschönes Heim an einem der schönsten Flecken der Welt zu verdanken. Weiterhin alles Gute für die gesamte Belegschaft und nochmals Muchas Gracias! Christine und Mathias

After purchasing our property, we were keen to modernise it. However, being new to the area and living in the UK, we needed a contractor who could offer a reliable, turnkey solution. That’s when we came across ProMas and after meeting Andy, it didn’t take long to realise we had found the right team. Throughout the entire project, we worked closely with Andy and Nona in person when we were in Spain, and via WhatsApp and email when we were back in the UK. The communication was seamless, and with near-daily updates, we felt completely at ease from start to finish. The whole team brought an impressive level of experience and professionalism that far exceeded our expectations. We couldn't be happier with the result and would highly recommend ProMas to anyone looking for a stress-free renovation in Spain.

Where do I begin!!! Andy, Nona and all their Team are some of the best professionals on the Coast. We purchased a Villa which needed renovation work, so I contacted a few companies through a quick Google Search, and WOW am I glad that ProMas was one of them. From the beginning they were so professional, taking notes and really listening to what we wanted to achieve, they drew plans and designs and mood boards before even commencing. We ended up double the renovation project as we felt we had the best people at hand, so they have created the most amazing home for us. The standard of finish and quality is incredible, the continuous feedback and check-ins were great and MOST importantly, they stand over their work, even to this day if we have any minor snags (Which is to be expected), they come and sort it - I don't know many companies that would bother coming back after you've paid them no matter what the issue. Overall, Andy and Nona made our dreams a reality and created a WOW Villa, they maintained the Andalusian charm on the outside, and created a modern masterpiece on the inside. It doesn't end there, they even offer other professionals such as Landscapers etc to really give a full service. I would highly recommend!!!

Incredibly happy with the quality of the work from Promas in transforming our apartment in Elviria.  All aspects of design, advice, materials, build quality and communication were first class. The team were a pleasure to work with and Andy’s exceptional communication and video updates of the site progress meant even though I was in the UK I was always kept up to date. I couldn’t recommend Andy and the team more highly and am delighted with the finished work!

We were very hesitant after purchasing our house in Marbessa Spain, and went to multiple building companies to get quotes for the villa restoration. My husband being in the demolition and building game himself had high standards as to what we expected to be delivered as a final product. Well there are no words, absolutely none as to how phenomenal ProMas Building were with not only managing but beating our expectations! Andy and the team were direct with us as to was and wasn’t achievable as we didn’t want to demolish the house but they came up with such inventive ways to keep the character of our Andalusian villa intact whilst bringing it in to the modern day. They thought ahead for us of what it is like to experience the different seasons of Spain, really living there and what we might require with the weather changes and our changing family with little children to older relatives coming to visit. Mohammed and Nona were so welcoming with my ideas and even when I felt lost in how I wanted a room or where I was going with it, they just seemed to know how to make it work. Not even just work they brain stormed, gave me option upon option of what was needed and took all the stress away. They always delivered on time (realistically on two occasions they didn’t but that was due to a manufacturing problem and a delivery driver shortage) but this fortunately didn’t hold anything up and the team were keen to carry on working on other elements of the project so no time was waisted. Cost wise my husband dealt with all the financing but I do know I never heard any complaints from him and he mentioned multiple times that he could see where the money had been spent. ProMas as a team are people who we have whole heartedly trusted with our family home and for their finished results, support, trust and kindness that they have given us we cannot recommend them enough! And we will be using them again and again for any future projects. Please contact Promas if you wish to speak with us directly for our phone number or any photos and we would be more than happy to talk.

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!
