A fabulous new basement in Kingston

We engaged Advantage Basements in Sept 2011 after a year of debating whether we should go ahead with a basement (the move or improve conundrum!). Throughout our period of indecision, advantage were supportive, both being available and more importantly not pressing to 'close the sale' at a pace we would not have been comfortable with.

Oct 11 to Feb 12 flew by in a series of planning and permission meetings and before we knew it, the (aesthetically pleasing) hoarding was up and digging had commenced!

Our job started end Feb and completed to schedule and budget by end Oct. Throughout that period Steve and David, brilliantly supported on site by our foremen Gheddon and Nick were always available, helpful and willing to go the extra mile. Our fears on noise, dirt, impact on pedestrians and neighbours and general disruption to daily life proved broadly unfounded by the skill, effort and dedication of the sites teams.

We are left with a basement we are immensely proud of and a great new space in which to play, relax and entertain. We would wholeheartedly recommend the advantage team to anyone considering a basement to deliver the same! We definitely think it's put the 'Wow' factor into our home!

Another Happy Client in Putney

I just wanted to congratulate you and the team on an excellent project to create additional living and storage space under our house. The work was completed on time and to budget, both rarities in my experience, and to a very high standard.

It is invidious to single out individuals for praise as all were professional in wanting to make sure that we, as clients, got exactly what we wanted, that things happened when they were promised (often difficult when specialist subcontractors are involved) and that site meetings took place on time. Chris as Project Manager, Manu and Lyubo as Foremen deserve particular mention though.

As you know we were concerned about the impact on our neighbours. I have to say that the team quickly converted them from sceptics to fans, the site was kept immaculate and noise and disruption to a minimum.

I have absolutely no hesitation in recommending you to anyone contemplating a cellar or basement and wish you every success in the future.


Basement Conversion within 6 Months, Barnes - London

Advantage Basements built our basement within 6 months and we are really happy with the result - it has provided extra storage, a laundry room, a wetroom and a large living space for our 3 children. All the Advantage team were helpful and hard working and managed to start and finish the basement within the agreed time. We had an excellent foreman during the fit out who was helpful and highly skilled and the digging team leader was also helpful and considerate. It was also reassuring to know, too, that there was a structural engineer who was available at short notice if we had any concerns in the Dig phase.

I would highly recommend Advantage Basements.

An excited basement conversion owner in Golders Green

We have done a lot of building work over the years but the creation of our basement was by far the most exciting and gratifying work yet.

We were most impressed with the professionalism, care and support that the Advantage Basement and Cellar Company has demonstrated from the very beginning and right throughout the project. The company also excelled in guidance in all matters from the outset to an exeptional level of after care.

We do hope that we will have opportunity again, at some point in the future, to employ the company for further work and in the meantime wish them all the best with their basement and cellar conversion business.

A very happy cellar conversion owner in London

I am very happy to recommend Advantage Basement & Cellar Company London to anyone considering a cellar conversion. Actually, I'd also recommend a cellar conversion in general - if Advantage Basement & Cellar Company do it.

We now have a house that works sensibly with all the utilities downstairs out of the way and a soundproof room for exercise and music that doesn't disturb the neighbours.

If you are going to do a cellar conversion you really must use a specialist. The whole Advantage Basement & Cellar Company crew, from the bloke with the shovel to the directors, are very good at their jobs. We tendered the work and Advantage Basement & Cellar Company were fairly priced. However, it was only once we got started that we really saw how good a choice we had made. Advantage Basement & Cellar Company are growing because they really work at giving great service. We always felt confident that we would get an excellent result for the money we spent and for all the dust and disruption we went through. So it has proved to be - we now have a new favourite room in our house and it has all been very worthwhile.

I'm really glad not to have to go through such major works again but, if I had to, I'd choose Advantage Basement & Cellar Company - definitely.

Proud owner of an Advantage basement conversion near Northcote Road, Clapham Junction

Advantage Basement company was engaged with the basement conversion of our mid-terraced property from March, 2009 to October 2009.

We had originally engaged with another basement conversion company, but became increasingly frustrated with their lack of responsiveness during the planning application process, the preparation of structural engineering drawings and the applications for party wall agreements, and hence decided to reopen our bidding process for the full works for a couple of additional companies including the Advantage Basement company.

This was a great decision, as we have been fully satisfied the Advantage Basement company throughout the process. This includes initially working with their commercial manager Steve through the sales and contract negotiation process, and working with David, our programme of works manager throughout the build process. We also had fantastic support from Vasilev and his team during the 12 weeks excavation process which was completed spot on time, and working with Chris and his team throughout the 1st and 2nd fixing stages. The team has been very responsive throughout the whole process and both Vasilev’s and Chris team’s was very polite, organised, and very tidy throughout the works.

David was very patient with our requirements throughout the process and also very helpful in connecting us to suppliers and other people who wanted to work with throughout the process, incl. Michael Quinnen, from Indigo Blueworks, our architect.

This was a slightly more involved basement conversion of a mid-terraced house, as we required more rooms incl: a family/media room, a wellness room/gym with sauna and steamroom, a cloakroom, a wine storage room, an extra bedroom with an ensuite shower room and utility space for washer/dryer units and general storage.

The end result is a fantastic space where we have everything we could have wished for and with room for our family to grow.

A very happy client in Kew

Well - what can we say!?!? We have never had more organised, considerate, professional and considerate builders. Our basement is spectacular - better than we ever expected - and now the centre of our childrens' lives!

Having delayed doing it for a few years thinking that it would all mean a huge upheaval, it was unexpectedly pain-free. From first visit to completion of the project and subsequent quality control, the Advantage Basement teams exceeded expectations. The hard-working digging team had the project cleverly phased such that earth out and concrete in was carefully coordinated and within 12 weeks we had our shell (900 + sq feet of it). They were considerate of noise, neighbours and possible traffic congestion along our busy road.

Then came the fit-out team with much the same vigour and attention to detail, consulting with us at every key stage to ensure that we were happy with how the project was shaping up. The external tradesmen (electricians, plumbers, door & window suppliers etc) were all top-notch and so incredibly helpful. Nothing was too much for anyone.

We also had the decorating team in to put the final touches of paint and wallpaper. I have already recommended them to anyone I know - I have no hesitation whatsoever in doing so! Thank you Advantage Basements for helping my husband's dream of a media and games room come true!


A more than satisfied new basement conversion owner in Clapham

We thoroughly recommend Advantage Basement and seller company for the basement conversion that they carried out on our home just over a year ago . It has provided us with all the extra space that we desired to cope with our 3 children, freeing up a lot of extra space . The work was carried out in a professional manner and everything came in on budget. If there were any questions or worries these were smoothed over by Steve and our main project manager, David .

The fit out after the digging had taken place was completed to a very high standard by Ivan and his team. Everyone was very courteous in the whole process. The follow up and snagging process was all very efficient . We did have a couple of problems which needed sorting out and David was again helpful in the process , relieving any stress on ourselves , with their insurance cover adequately sorting out our situation.

A professional basement conversion in Wandsworth

We contracted with Advantage to undertake the full structural work and fit out of our basement in Autumn 2010; of the 5 professional basement companies we initially contacted to quote for the work, Advantage stood out in terms of the experience of their team, efficiency of their processes, financial stability* and competitiveness of their pricing. We visited a number of properties they had renovated or were in the process of renovating, and were impressed with the quality and finishing of their work.

Once work had commenced, the Advantage teams were well supervised, worked efficiently and remained on schedule for the majority of the structural and fit out stages. My wife and I were reassured that the job foreman and managing director organised regular progress meetings and were always sympathetic and responsive in dealing with our concerns; I felt that all the Advantage staff top down - the foreman in particular - had a 'customer first' mindset: if the work was not 100% to our satisfaction, they would review it and work with us to find a solution that worked for us. They were mindful of our budget and were always clear in signalling the impact on overall costs. They also helped us remain on good terms with our neighbours, by scrupulous tidying of the site and skip every day, and by listening and dealing with concerns over party wall cracks.

We are very pleased with the final outcome and would recommend Advantage to any householder planning a major basement refurbishment.

*[2 of the 5 companies who quoted for our work subsequently ran into major financial difficulties, so I would not underestimate the criticality of choosing a company with a strong balance sheet and cash flow]

Andi B.

A proud owner of a Basement & Cellar Conversion in Clapham

Deciding to go ahead with a basement conversation is a big decision for anyone: it took us over eighteen months from when we started thinking about it until we actually decided to go for it, and then it was another six months before the building work could begin (as we live in Lambeth). During this time, we saw numerous basement companies and received a variety of quotes. From the outset, we were impressed with Advantage Basement & Cellar Company as they were totally professional and personable and also appeared to offer more of a bespoke service than some of their competitors and, importantly, they were competitively priced.

We’ve been involved with numerous building projects over the years and, without doubt, our recent basement conversion has been the most stress free and enjoyable (if you can call a building project that!). Yes, of course, there was dust, mess and noise, but not nearly as much as we had been expecting. Despite our basement being one of the most structurally challenging Advantage have undertaken, what made a real difference is that throughout the entire project, Advantage made us aware of when it would be exceptionally noisy/dusty etc, so we could plan around this, which was relatively easy to do, even with two small children.

Now, a couple of months after completion, we couldn’t be more delighted with the end result. We have around 1,000 extra square feet of great additional living space which is light and airy. It’s made up of a huge playroom/media room, a fabulous wine cellar, additional downstairs loo and sports storage cupboard, as well as a bedroom with ensuite shower room and a small kitchen so, in effect, a self contained flat.

We couldn’t recommend Advantage more highly for anyone that is planning to carry out a basement/cellar conversion and would be more than happy for any prospective clients to contact us with any questions/concerns or to come and have a look at the end result, which speaks for itself.

I can highly commend the Advantage Basement & Cellar Company for an extremely professional basement conversion they carried out on our home in Wandsworth.

The whole process from the initial enquiry right through to the completion of the work was extremely well managed and implemented and I would have no hesitation in recommending your company to potential customers considering a basement conversion in London.

Yours Sincerely

Delighted owner of a basement conversion and kitchen extension in Clapham

We had Advantage Basement Company to construct and outfit a large basement (sixty square meters) and kitchen extension. They undertook all the works including structural, plumbing, wiring and outfitting.

They're performance, scheduling, cost control, risk management and quality was outstanding. They offer a personable, professional and friendly service. It's an integrated service that I would recommend to anyone, and as a professional engineer used to large construction projects you cant beat them

Another happy customer - basement conversion in Balham

The Advantage Basement team were thoroughly professional, courteous and diligent throughout every step of our basement from the initial planning application to the final finishing touches. Nothing was too much effort, there was always someone with whom we could discuss progress and disruption was kept to an absolute minimum.

We can't recommend them highly enough - a joy to work with!

Melanie & Robert

A happy new basement owner

I chose to use Advantage Basements when taking the decision to undertake the huge task of demolishing my two-storey detached house, then designing, excavating and building a lower ground floor and restoring the original features of the house exterior. They were the obvious choice as I was impressed with the quality of their previous work, the quote they provided and the fact that I trusted them implicitly. Working closely with Steve and David, I can say that the communication was fantastic! Throughout the whole process I was kept in the loop about what was happening and any new developments.

The team provided an excellent service both through the design process and the actual building work. Time-wise, and budget-wise, things went pretty much to plan. They listened, gave sound advice and captured the original theme to match the neighbours' houses. The results are nothing less than stunning- and it was a big but very welcome surprise that the project won an architecture award!

I would highly recommend the services of the Advantage Basements team to anyone wanting to to undertake a conversion project as you can be rest-assured they are efficient and reliable. I look forward to working with them again should I decide on any future renovation or building projects!

Tanya M.

Another happy client and basement owner

We have no hesitation in recommending the team at Advantage Basements that worked on our project. Our basement conversion was completed in just over 4 months and provides a high ceiling games / family room and utility room, plus storage space.

The whole project was extremely well managed. The foremen in charge of the structural and fit-out teams require special mention for their professionalism, diligence and client focused approach. We were impressed with their teams' tidiness and consideration for our neighbours.

Our project was delivered to a high specification, on schedule, within budget and with minimal 'snagging', which was promptly dealt with.

We are extremely pleased with the end result. Thank you Advantage Basements.

Matthew & Sarah

New basement owner

Advantage Basements have a well rehearsed formula allowing the construction phase to smoothly follow on from the design. They engage a professional contracts manager who liases between the site personnel and client and whom is invaluable to the process. The project was completed on time and to the quotation agreed. A thoroughly professional outfit who are to be recommended.
