Our Testimonials

We’ve had Cellartech complete two extensions for us now and I wouldn’t hesitate to use them again. Ian and his team are hard-working, reliable and thoroughly invested in working with you to give you what you want. They keep a really tidy site (they often left our house tidier than they found it!) and turned both jobs around in super-quick time. Ian’s regular communication is second to none and his vast array of connections allow him to line up trades for exactly when you need them. All in all we’ve been very satisfied. Oh, and they were the best priced quote each time!

What more can we say? Unbelievable!
Ian and his team of dedicated contractors completed our cellar conversion to an exceptional standard. They turned up at 8am everyday and finished at 4.30pm.  The team are polite, friendly and a pleasure to have around. Ian will put you at ease at a stressful time. Nothing was a problem! 
He had some fantastic ideas, which we utilised and the site was left clean and tidy every night.
Ian was always available on the phone and when problems did arise, Ian sorted them using professionals such as structural engineers, architects, building control.
We cannot recommend Cellartech enough!
Very pleased client!


Highly recommended.

Ian and his team were a hard-working, experienced, friendly bunch.  They always turned up on time, worked hard and left the site cleaned up at the end of the day.  Ian worked hard to ensure that the build kept within our timescales and amazingly pretty much within budget.  Our experience went very smoothly with no major issues, but if we had any issues or questions Ian was always on hand to offer his advice and come up with a solution.  Ian even helped us to set up a temporary kitchen for use while the build was taking place (complete with old sink and running water!).  We’re really pleased with our finished extension and would definitely recommend Cellartech as a reliable, competitive building company.

We have used Cellartech on many occasions now to help us with below ground solutions. From the design stages through to the installation Ian and his team have done a great job. Do not hesitate to contact Cellartech if you are after a new installation or have an existing issue with damp.

We used Cellartech to build our house for us. Ian and his team did a fantastic job. His communication throughout the whole project was fantastic and kept our minds at ease throughout. Ian has some great ideas and suggested some changes to the internal design on the plans for the better, because his experience meant that he could see an opportunity to improve on the architects design as the build unfolded. This was amazing as the living space works better than what was originally planned.

The quality of the brick laying is superb, it’s one of the things that strikes you when you first approach the house and one we get many compliments on. The quality of other trades Ian uses were very efficient and reliable.

The site was always keep clean and tidy as possible which was a relief to us and our neighbours.

Overall we had a very good experience with Ian and his team, they are all friendly and approachable, and most importantly knowledgeable. We would use them again for sure.

Paul & Sarah H

We had several quotes for our renovation project but Ian’s wealth of knowledge stood out above the rest! We discussed all the detail of the project in depth to ensure it was feasible and would work for us.

Ian has a great, hardworking team of people, along with the other tradespeople he works with all aspects of the build were covered. We felt comfortable with all the people that worked on site, they were extremely knowledgeable and had some great ideas to enhance our project.

Clean and tidy site, great communications, project completed ahead of schedule – we certainly fell on our feet when we chose Cellartech! 100% recommend Ian and his team and we would be very happy for people to see our house.

Cellartech converted our basement for us in 2022. Starting from soil underfloor and bare brick walls and leaving us with a beautiful warm, dry space. 
Ian and his team were fantastic from start to finish, always on time, friendly, trustworthy, professional, great at communicating with us and our neighbours and the work was performed to a very high standard. The original scope was completed to cost and (despite us adding in extra scope during the project) on schedule. Great value for money. 
Ian is now our first port of call for any building work we need doing. Would definitely recommend.
Nat & Phil

We were recommended Ian / Cellartech from a friend who is a head consultant in the building trade for larger projects/ developments.On first meet Ian was a “character” – friendly & reassuring & we instantly had a good feeling & trusted him … we were not wrong!Any build is potentially stressful but Ian took over the project management & build & we didn’t have any worries. His knowledge, unlimited contacts from suppliers, joiners, plumbers, electricians was exceptional. Not forgetting his excellent building team.They turned up 7.30 on the dot everyday. You could set your watch by them & we had the kettle on ready, it became a nice start to the morning with a coffee & chat. They were polite, friendly & the site was always clean when they left.A fantastic job was done, excellent workmanship at a great price. Ian & his team have years of building experience & it shows.We can not thank him enough & are proud to show off our home. Ian has also recently completed a small build for my elderly parents & they couldn’t be more delighted.When the build was complete we were sad to see them go. Ian has gone from being our builder to our friend. He won’t let you down.

Rach & Scott

Cellartech was recommended by our architects and smashed our expectations. The work is phenomenal and completed months ahead of when we anticipated. I can’t say enough good things about the experience. Ian and his crew made a very stressful time far easier for us.

Luke S

Ian and his team were really friendly, enthusiastic and hard working.

They arrived nice and early each day with a smile on their faces and a quick chat before getting down to work. Each day Ian would keep us updated with progress including pictures which was really helpful. He was also always willing and knowledgeable with any questions we had in the build which would put our minds at rest. Ian also worked hard to ensure that the build kept within the predicted timescale.

We are very pleased with our new cellar , it looks fantastic. Big thank you to Ian and the team.

Ian is hard working, efficient, reliable and a tidy worker. He has completed work for us on many occasions and we have never been disappointed. His work ethic is second to none and we would highly recommend him.

Mr Malcolm W

Ian Breach from Cellartech was recommended to me by a friend who had had some fairly extensive work done on a bungalow he had recently purchased. I had just gained planing permission to convert my convenience store into three apartments. I had no previous experience of doing developments and my two key concerns were the project going massively over budget and the time-frame for the work increasing.

Cellartech completed my project on time and were on site for the entire three months of the build. There was not one day when they didn’t turn up for work. I understand this not to be the norm in this industry as builders usually juggle many jobs.

The work was completed on budget, although we made a few changes to the plans along the way as Ian recommended improvements and savings as things progressed.

Ian Breach and his right hand man, Sean, have over 40 years of building experience between them and any problems we encountered they found a sensible solution for. Ian also has a large network of tradesmen that he was happy to share with me for other parts of the project that were not in his remit.

In summary, Ian and his team managed and completed the works with minimal input and stress on my part, on time, on budget and to a standard I am more than happy with. I intend to use Cellartech again in the future.

Well we had a huge double extension 6 years ago by Ian, with bi-fold doors, velux windows, very large new kitchen etc, and lots of extra detail put into things.We have not had a single problem with anything. So we were confident to use him again this time, he’s just done a small double extension on the side of our house for a study at the bottom and he added a en-suite to an existing bedroom at the top. If your anything like me and have a change of mind on things, Ian is always happy to please the client, I made several changes!

I am 100% happy with the standard of work, Ian has a really good team of contractors and he project managed the job really well, so we were not waiting for anyone to arrive, things were very well timed. He also has some great contacts in a lot of areas (we got discounts on a fitted bedroom) and he knows the best places to shop for other materials. Sean and Kyle (his team) are fab, Sean is extremely knowledgable and Kyle is a lovely lad, very trustworthy, I left my home in the day and they had full access,  No negatives at all really, just to be mindful that Ian is a colourful character, not everyone’s cup of tea, but we certainly enjoyed having him and his team in our home. He made us all laugh every day with his “banter” and stories. Just remember to keep the kettle on and stock up with good coffee and you will be off to a great start.
