Kezia Smith
London

We were quoted a very good price at the time. The builders were great and did a fantastic job to a very high standard. They had amazing plasterers and carpenters but communication with the team could be much better.

Lottie Berridge
London

Great service. All the trades involved were courteous and polite. No hidden costs, the price we paid was the price quoted. Highly recommend.

testimonial-team
Malcolm Springett
London

So from the very beginning SMA were excellent. The initial meeting to discuss the job produced a detailed quote (including a plan of what was to be paid at what stage) and drawing (not final drawing but enough to have a good idea). Once work began it was incredibly quick and efficient. A Whatsapp group was created for all involved which meant all the contractors knew which days there were due in and of course we knew what was happening when and the work was done extremely well and everything kept tidy. Very happy to recommend SMA and in fact wish I had another loft to convert!!! 🙂

Patrick Brennan
London

SMA converted our loft into a work/family den space. The work was of a high standard and their approach was open and professional. It was a relatively painless process and didn’t disrupt our work or private lives.

testimonial-team
Sarah Coe
London

SMA were excellent from beginning to end. On time and on budget. Courteous and professional staff through out. They were oroblem solvers and energetic in delivering a great build for their customers. Clean and tidy in every aspect and unfailingly cooperative and friendly. We are delighted with our loft and highly recommend SMA to anyone wanting an end to end service for their loft project.

testimonial-team
James Wright
London

Exceptionally pleased with both the end result, and the process itself. The building teams as well as the management were great to work with. Whenever there was an issue, the result was a better one, rather than a workaround. For example, we now have a walk in wet room style shower which wasn’t originally planned… We have matching coving which blends the old part of the lounge to the new. Pretty much all issues were dealt with as we went along, which meant the snagging list at the end was miniscule. Plus SMA introduced other excellent skilled trades people to finish the job.

testimonial-team
Mrs Hooftnan
London

Very happy with the work and the communication with the company. All very clear and no unexpected additional charges. Efficient and approachable.

Dr Louise Allnutt
London

SMA are a very organised and reliable firm. The finish of the loft is exceptional and we are very happy. The main benefit of hiring SMA is their ability to trouble shoot and resolve issues within a very short time frame. We really recommend SMA.

testimonial-team
Mr Iain Reilly
London

All in all an excellent experience. From initial consultation through to final walk around we were well looked after by all the SMA team. They really understood the specifics of the loft build and often offered advice to help ensure that we were really getting what was required, not just what would have been the simplest outcome for them. I would not hesitate to recommend SMA to anyone looks for a loft conversion in London, you won’t be disappointed.

testimonial-team
Ms Katy Sawyer
Northwood

Excellent work by really knowledgeable and trustworthy workmen. They also went out of their way to ensure relations with the neighbours were good throughout the build. The entire team were exceptionally determined to get the work done quickly and in time for my baby to arrive – which they did, and maintained a really high-standard of craftsmanship throughout. It must be a rarity in the industry: it was finished early and under-budget. We love our loft conversion and would recommend SMA Lofts to anyone.

testimonial-team
Mr Jeffrey Musgrave
Brentford

I cannot speak highly enough about the quality of work SMA did. Everyone, the builder, plumber, electrician, plasterer, carpenter, sales, Sam and office staff were totally professional in everything they did. We were given advice and options throughout the process and gave us ideas about things that we had not even thought of. The builder explained things as the build progressed. The quality of the plasterer made decorating easy. The electricians asked and advised about positioning lights and sockets. The carpentry and plumbing was fantastic quality. I would highly recommend this company.

Mr Anthony Brampton
London

A highly professional job from start to finish.

testimonial-team
Mr Sam Austin
London

The SMA team were excellent. They were prompt, tidy and brilliant at keeping us in the loop/ updated with what was going on. The team completed the work on schedule, to a high standard and to the design/ spec we agreed. They were also able to flex their delivery dates to get the work done before the birth of our daughter. I would highly recommend them.

testimonial-team
Mrs Tilbury
London

We highly recommend SMA Lofts. From the initial quote to project sign off, the service we received was brilliant. Builders, electricians, tilers, plumbers, plasterer, carpenter, roofer were all very professional, knew what needed to be done and got on with it. They were also really friendly and helpful. It was a well-oiled machine. The finished loft bedroom and en-suite bathroom look amazing. To say it was a big job, it was very hassle/stress free for us. Thanks SMA Loft!

Mrs Hannah Stringer

All tradesmen were courteous and completed their work to a high standard. We are really pleased with the result. It was completed with minimal fuss or disruption to us. I would definitely recommend SMA.

Mr Roger Sillence

We are extremely pleased with all aspects of the work, from the planning to the final decorating. I strongly recommend using SMA lofts if you’re thinking of a loft conversion.

testimonial-team
Mr & Mrs Mankowitz
Ealing W5

This is the second loft that we have constructed through SMA, which says it all, really. We had no hesitation in using them after our first loft conversion, as the service that we received was absolutely first class. The process was made clear and transparent from the start, and the whole team were an absolute pleasure to deal with. Whenever there were any snags to deal with, (of which there were very few!) Sam was always available to problem solve, and really showed an attention to detail that was very much appreciated. I recommend SMA to anyone who is thinking of doing a loft conversion.

testimonial-team
Mr & Mrs A Foster
Twickenham TW2

We are so very happy with all the work you have done for us recently. The loft is amazing; the standard of work from day one was second to none, from organisation, quality of work, politeness of all the men, always leaving the site tidy every evening. The downstairs extension – kitchen was far from straight forward for you; however nothing was too much trouble for Sam & his great team. Scott McCabe Associates (SMA) stands for quality & expertise. We are so happy we were recommended to your company and will recommend you to anyone who asks who did our work. The kitchen space is more than we could ever envisaged, the result is truly amazing, thank you.

testimonial-team
Mr & Mrs Beckett
Brentford TW8

We’d like to thank you all at SMA for the successful completion of our project, on time and to budget. All you associates were courteous and polite and the work was finished to a good standard.

Mr & Mrs Thackery
London W12

We are delighted with the result. The whole process ran very smoothly and efficiently with minimal disruption to our busy household. Craig was excellent and worked unbelievably fast at the start of the build. He was great fun and always cheerful. Andy (Sparky) was also great, and nothing was too much trouble for Sam who project managed everything and always came over at the drop of a hat if something needed sorting.

Jean-Luc Eberlin

The loft conversion was done to a very high standard and I am delighted with the end result.

Paul Dixon

We are very pleased with the final result. Everyone who worked on site were very helpful and professional. Very happy with all of them.

Fiona O’Reilly
Twickenham

The process of doing the conversion was as painfree as such a major structural change could be. I was kept fully informed about what to expect at each stage and the team were a pleasure to work with. They were highly professional, stuck to their commitments and went to great trouble to keep thing tidy as they went. The final snagging list was small and all the items were dealt with immediately and professionally. I was delighted with the overall result. All four were also genuinely lovely to deal with, explaining clearly what needed to be decided by when and what all the options and tradeoffs were (a real bonus for a single woman).

testimonial-team
Will Hurst
London W7

The conversion went extremely well. It was done incredibly fast we thought with less disruption than we imagined. The final result is truly superb and lots of people have commented on what a good conversion it is.

testimonial-team
Mr & Mrs James
Ealing W13

What can I say? Thanks so much for all the hard work on the loft, it’s been a pleasure having the team around. From day one, everything happened both smoothly and efficiently. I’d prepared myself for there to be so much more disruption and mess, however it never materialised other than what would normally be expected on a project of this size. A big thanks to everyone involved for giving us such a beautiful loft conversion. I will most certainly be recommending you to our friends and family in the future.

testimonial-team
Colin Dolphin
Northfields W13

Thanks to you and all the gang for a job well done.

testimonial-team
Bowden & Ms Cooner
Chiswick W4

Thank you very much for your teams hard work, the loft is great and we are very happy with the outcome. Sam was excellent and we would be happy to act as any reference for your customers.

testimonial-team
Mr & Mrs Richie
Wimbledon SW19

In general, we are delighted with the result of our loft conversion. The quality of workmanship was outstanding and the cooperation and willingness of your team were exemplary. Neighbours in Dora Road have commented on the speed and efficiency of the external build as well as the very high standard of finish and minimal degree of disruption to themselves.

 

If we were to do the conversion all over again, I don’t think that we would change anything significant.

 

In so far as individual contributions are concerned, we would like to mention in particular Teresa Mahon, whose help and advice in preparing the initial specification and offer document was quite outstanding. No details were overlooked or left to chance and her meticulous attention to detail resulted in a very smooth running project. As far as the build itself was concerned I cannot commend Craig more highly. The initial build was completed in only 3 weeks which was remarkable and disruption to our domestic life was considerably less than we had expected. His work ethic, commitment and willingness were absolutely first class. I should also mention Sam whose role as coordinator and trouble shooter was much appreciated, especially considering the obvious demands on his time from other ongoing projects. Brian Covell in the office was also most helpful in the latter stages of the project. The individual craftsmen were all first class, in particular the 2 Roofers and Sean the Carpenter.

 

For all that, we would have no hesitation in recommending SMA to anyone considering a similar project. in fact, we have already sung your praises to a number of our friends.

testimonial-team
Howard Jones
London N4

We were delighted with the Dorma SMA built for us. The work was completed within the specified time frame and the price quoted at the start was the price we paid at completion. The work was carried out with an absolute minimum of disruption and to an extremely high standard.

testimonial-team
Annabel Askham
Teddington TW11

We are really delighted with our new loft and shower room and the experience was so much better than we anticipated! All your team without exception, are extremely hard working and thoroughly professional.

Jacqueline A
Ealing W13

I would like to thank you all for the excellent work and service you provided over the summer months in relation to my loft extension. The new space is just wonderful and just what I dreamed of. I have had lots of admiring comments and praise from both family and friends.

 

I particularly appreciated the way the team worked together and the ‘can-do’ attitude and professional work of all involved from the very start of the project. Although everyone worked very hard to meet my deadline at the end of September, good humour always prevailed. When some minor problems occurred, they were resolved swiftly and efficiently. I have nothing but praise for your company and would certainly recommend you to anyone thinking of extending into their loft. I shall also contact you in January to organise some other ground floor extension work I would like to do in my house in May or June 2014.

 

May I especially commend the work of David Ward at the design stage, of Bobby and Sam whose supervision was excellent and, last but not least, of Laura without whom the wheel would grind to a halt. She was extremely good at co-ordinating, very patient with me throughout the project and acted fast and efficiently, for which I would like to thank her.

 

I wish you all a very happy end of the year and well-deserved rest over the holiday.

testimonial-team
Mrs Nicholas T
Fulham SW6

This project was my first loft conversion, and in fact the first time I had ever employed a builder for any significant amount. I went with SMA, even though their quote was slightly above the other two, because their people were very supportive, and appeared more experienced than the others.

 

This decision was justified by events, as the project progressed smoothly, being completed on time, to budget and to a very high standard of workmanship.

 

My aim was the maximise value on the property prior to sale, and the property was sold at a very favourable price within three days of being put on the market.

testimonial-team
Mr Mark W
Hampstead NW6

It went well, and I’m very pleased with the result. We had discussed at the beginning of you quoting for the works downstairs (e.g. the new kitchen), we didn’t really follow up on it. In hindsight it would have been great to have had a single contractor for all the work. Emmet and Phil were superb. It was very good, I would highly recommend SMA.
