What people are saying about us


Carl & Martyn are exceptional contractors who have just completed another high quality extension, internal structural alterations and patio area to the rear of my property.

From start to finish the level of quality, detailing and workmanship was first class.

The site was always left immaculate with the level of disruption, noise and dust always kept to a minimum.

Nothing is too much trouble and they are both the nicest down to earth hard working lads you could ever wish to meet and I would always recommend them to friends and family.

Carl and Martyn came highly recommended to us and as soon as we met them we knew they were exactly who we needed for the job.

They immediately understood what we wanted to achieve and from the outset were able to come up with solutions to make it work. If a problem arose they already had an answer which made for a stress-free build and nothing was ever too much trouble. They both have a great eye for detail and work with tidiness and efficiency.

We started our project in July 2020, following the first lockdown and working from home with Carl and Martyn was nothing short of entertaining with superb singing, dubious rapping and endless cups of tea! It was a sad day when they finally had to leave.

Our extension has turned out even better than we could have hoped. Their excellent reputation was certainly exemplified in the quality of their work. We would highly recommend them.

Carl and Martin recently finished a small extension to our bungalow. The work consisted of knocking down the existing garage and building a dining room and kitchen extension.

The work was carried out over the Winter period and they had to contend with very challenging weather. Despite this the work was completed to a very high standard and with their help and guidance far exceeded our expectations.

We would not hesitate to recommend Carl and Martin for any building work large or small and we will certainly be calling on them in the near future for other projects.

We would also add that their ability to do a first class job is matched only by their ability to drink tea.

Thank you both very much.

I purchased a bungalow that required a partial rebuild and total revamp.
So I telephoned the only builders that I would trust with this difficult project.

Carl and Martin are much more than exceptional builders they advised and supported me throughout, transforming a visibly dated dwelling into a bungalow I’m proud to call home.

Carl and Martin were recommended to us by our friend who has seen their previous work. We contacted them and even though Carl was going on holiday, he took detail of the build with him and worked on a quote whilst away which greatly impressed us.
We started the build November 2016 and from the beginning any issues we had were quickly and professionally resolved by both Carl and Martin. They were always on time and had advise ready when we were in doubt. We cannot fault their workmanship and professional attitude.
Our home was completed October 2017 and we’ve already had numerous compliments on it’s appearance.
We have recommended Carl and Martin to various people and we would not hesitate to use them again if needed in the future.

P.S. One word of advise, a large quantity of tea bags is needed  to keep the lads happy throughout the day!

Guest and Roberts are wonderful builders and would recommend them without any hesitation. Having accepted their quote and start date, they where on site everyday, until the job was finished. Kept me in touch with every step of the work by text or telephone. Came in on budget, except for my upgrading some of the fixtures and fittings. I was warned before the start of the job about the foundations … So I added a little extra in the calculations, which I needed. Extremely happy with the extension which was on the site of a double garage.



Back in 2013 Carl and Martyn completed the build if my brothers house (Longview, Bryn Road, Moss). When going through the selection process we found the build decision very easy.

These guys are amazing at what they do. There attention to detail and passion has enabled us to have an amazin
g family home.

Hey are honest, reliable and took so much pressure of us during the build.

I would no reservations in recommending them and would happily open my home for a reference visit if required.

Carl and Martyn thank you for helping us achieve our dream.

Once we decided to build, finding the right builder was extremely important to us. After doing our home work we found Guest and Roberts who we know are reliable builders and would move at our pace. Guest and Roberts were honest, transparent and willing to work with us on every single detail to make our dream come true. No matter the day or time, we could always contact Carl Guest, this was a very important factor for us .

Our house is now built and we are thrilled with the results of our beautiful home. For anyone looking to build there dream home for a fair reasonable price, we would highly recommend Guest and Roberts. Thanks again Carl and Martin for our absolutely beautiful home, you are always welcome to come and visit.

Sandrock BackSandrock FrontNot many people have a good word to say about builders, so when Guest and Roberts were highly recommended to me by a work colleague as they had built his house, I invited them around to provide a quotation. They provided a detailed quote at a reasonable price.

Carl and Martin have been outstanding, not only have they provided a professional service but are totally approachable and easy to work with. As with any build, issues may crop up but Carl and Martin always helped us to work through any problems offering great advice and demonstrating excellent skills, no job is too big or small. Their craftmanship is second to none and we cannot find fault with any of their work. Not only are they punctual and clean, they are nice guys and were thoughtful and considerate of our neighbours too. We would highly recommend Carl and Martin and are extremely pleased with all the work they have done for us.

Guest and Roberts have just completed a four bedroomed house for us and we are delighted with the result. Carl, Martyn and their team are reliable, honest and experts in what they do and we would highly recommend them to anyone. Prior to and throughout the build, Carl & Martyn were in touch with any queries ensuring we got exactly what we wanted. If they required any clarification on any matters they would always pop round in the evenings to discuss before going ahead.

Guest & Roberts undertook the building work on our house to convert the integral garage to a playroom and provide replacement windows, doors, fascias, soffits and gutters . A first class job from start to finish. We found Carl & Martyn to be professional, hardworking, knowledgeable, tidy, reliable, honest and trustworthy. Nothing was too much trouble, the few problems that were encountered were quickly rectified with the minimum of fuss. We were particularly impressed with the high standard of quality and workmanship and their attention to detail. We would definitely use Carl & Martyn again and would have no hesitation in recommending them to anyone looking at having building work undertaken, including family and friends.

When we wanted a small extension on the front of our house we had no hesitation in contacting Martyn and Carl. From past experiences we knew the high standard of their work, and together with their sub-contractors they did not dissapoint us, this is the second extension they have completed for us and now as then we were fully satisfied with their work. We would fully recommend them to anybody.

Mr and Mrs ShawGuest and Roberts Builders Ltd carried out a bedroom with en-suite extension to our house over an existing kitchen, which was a challenging build due to location and access and without affecting any of the kitchen below and even kept the original ceiling which was fantastic considering the original roof had to be completely removed. From start to finish Carl and Martyn and associates were professional, knowledgeable in their field and carried out the initial inspections and liaised with the local authority building inspector to quickly get the work underway.

They arrived promptly every day without fail weather permitting until the roof was on then even the bad weather couldn’t keep them away. All work was carried out to plan and on time and to budget and to the highest standard. We are extremely satisfied with the work carried out on our home. We would highly recommend anyone thinking of undertaking any building work small or large to put your trust in Guest & Roberts.

Guest and Roberts Builders Ltd, carried out a sun room extension for us. From start to finish Carl and Martyn were professional, knowledgeable and gave us advice on “what would suit best” .

They carried out the initial inspections and liaised with the local authority building inspector to get the work underway as soon as possible. They arrived promptly every day until the building was complete. All work was carried out to plan, on time, to budget and to the highest standard, keeping us informed of their work plans and updates of progress daily.

They are a small operation who use contractors for their electrical, roofing, plumbing work etc, who were equally professional and delivered high standards of workmanship.

We would describe the work carried out by Guest and Roberts and their contractors as first class.

The sun room is fantastic and turned out exactly how we wanted it. Nothing was too much trouble.

We are absolutely satisfied with the extension; we highly recommend Guest and Roberts and would certainly use them again for any future building work we have planned.

Choosing a builder can be a daunting task. Can I trust the quality of work? The ability, the honesty and value for money of the people quoting for the work? I went through all that when trying to decide on a builder for my project, so I can make the decision easy for you! The work Martyn and Carl carried out for me involved extending my house in a number of areas, and was a large project to take on. Some aspects of the work required a great deal of technical knowledge and expertise to ensure the house was adequatley supported while main structural walls were removed. While some well known builders clearly did not feel capable of carrying out the work and did not present a quote, Carl and Martyn completed such tasks with skill and care, producing superb results. I have discovered that many well known builders you may appoint carry out little of the work themselves, and appoint sub-contractors to work on your house without any overall ownership of the job. In contrast, Carl and Martyn are on site all the time, carrying out the majority of work themselves supported by plumbing, electrical and plastering specialists who they know well and use regularly. Martyn and Carl are totally honest, trustworthy, are highly skilled craftsmen, and genuinely nice people. I am delighted with the results they have produced and if I should ever require further building work, i would not consider anyone else, I am happy for anyone to telephone me at any time for a personal recomendation.

I recently returned to live in England after being in South Africa for over 20 years, I decided to move into my sons house which had been empty for over 4 years and had suffered a flood in the bad weather. I decided to have a kitchen extension and after being let down by someone who started with the groundwork i contacted GUEST AND ROBERTS to quote for the work. Firstly i telephoned Carl who was on holiday in Tenerife! But who promised to come round as soon as he returned. As promised he was there on the dot. Regardless of the price he would have had the job, from my first contact he was honest, reliable and as it happened most competitive. I can only describe them as my Knights in shining armour. They arrived on site, knuckled down and did a fantastic job of the extension eating plenty of apple strudel in the process. At every stage the communication was unquestionable, snags were overcome and I can only describe the finished product as awesome. Not only have they done what was asked but they have done many extras and nothing seemed too much trouble for both Carl and Martyn, I would not hesitate to recommend anyone to use them for whatever the job and they will be top of my list should i need any other work carried out. I can only say that i feel very grateful and privileged to have met Carl and Martyn and thank them for all they have done for me.

Carl Guest and Martyn Roberts are a team of highly skilled professional builders who are supported by tradesmen of equal status.  Carl and Martyn are perfectionists in the quality of their work and in the importance that they place on good customer care.  I closely monitored their standard of workmanship during the building of my daughters house extension.  I was very impressed by the finished new build and did not hesitate in engaging them to build my garden room extention.  Carl and Martyn sought my feedback at each stage of work completion.  My requirements were their priority and my expectations were realised in full.  Needless to say, the end result is outstanding, built within the planned time frame and to budget.  Check it out.

Building firms don’t always come with the best of reputations, however, Guest & Roberts surpassed our expectations. The team were a delight to have around, they were very reliable, honest, trustworthy and thoroughly nice people, they always arrived on time, worked diligently and always tidied up at they end of the day. Costs for the work were clear and fair from the original quotation to completion – no nasty surprises or hidden extras. I very much appreciated that they were always contactable and always responded if telephoned for whatever reason nothing was ever to much trouble.

May i take the opportunity to thank Guest & Roberts for the excellent work which they carried out for us, we were impressed with their “old fashioned values” i.e.builders who take pride in their work, who are hardworking and completed tasks to a high standard. Most impressive of all was the respect and courtesy they showed for our family situation – they showed awareness of the challenge it can be living with building work on the go and they tried to minimise the disruption where they could and would give daily updates of how work was progressing. We are delighted with the finished result and we would recommend Guest & Roberts without hesitation to anyone who is looking for quality workmanship in the future.

I chose to have Guest and Roberts carry out the work I had planned after seeing several of their projects completed at other houses locally. I knew the quality of their work before they began. I am delighted with the work now it has been completed.

Kitchen ExtensionGuest & Roberts, or should I say, Carl and Martyn are builders. They are not businessmen in suits and ties, they build. They came recommended by a neighbour who had recently had a house built. Two down to earth guys, what you see is what you get. Knowledgeable in their field and always happy to offer advice and ideas.

They are a small operation with two other guys working with them but they have a team of experts behind them who they use to do their electrical, roofing, joinery, plumbing etc. The only way I can describe the work they did for me is “stunning”. It is exactly how I wanted it. Nothing is too much trouble and when there is a glitch (as there always is) they soon get it sorted.

I highly recommend Guest and Roberts, in fact they are doing work for my mum at the moment. If you would like to see first hand the work they have done for me please do not hesitate to call and I will show you around.

Complete house buildGuest and Roberts were employed to complete the construction of my three storey, four bedroom house in 2006. My wife and I can recommend them with utmost confidence. The inevitable pressures associated with housebuilding were eased by the professional approach of the two business partners.

A sensitive, well informed dialogue was maintained throughout the build. Regular, constructive consultation was a strong feature of the client-builder relationship . Deadlines to complete various stages of the work were met and unnecessary delays were avoided.

Minor obstacles associated with a new build were discussed fully and promptly and satisfactory outcomes were achieved. Their employees and specialist sub-contractors were courteous and conscientious and did not compromise the high standards set by Carl and Martyn. Site safety and general organisation of materials and equipment helped the build to proceed smoothly.

We were delighted by the completed building and feel that Carl and Martyn shared our pride and satisfaction with the end product. We recommend them with the utmost confidence.

Carl and Martyn and their team built our extension for us a few years ago. From start to finish, we could not have wished for a more professional  and thorough build. They made what could have potentially been a difficult and`tricky`project into a smooth and professionally executed build. Their attention to detail and general workmanship was un compromised, the whole way through the renovation process. We are more than happy with our finished article and wouldn`t hesitate to recommend and have on many occasions recommended their services to friends and work colleagues. We wish Carl and Martyn all the best in the future
