Here’s What Our Customers Say

Flooded basement transformed into a brilliant useable space

When Sati and the team started in our cellar, they were literally wading through water. Throughout the project, the disruption to the rest of the house was virtually non existent and we have ended up with a brilliant, useable space. Great people, excellent workmanship and fully informed all the way through. Highly recommended.

Gavin Slark

Punctual, reliable, tidy, friendly, professional, trustworthy and very efficient

We had a problem with damp in our cellar and asked Iceberg Developments to take a look and assess what needed to be done. They very quickly came over and thankfully were able to start the tanking job very soon after providing us a quote. All the Iceberg staff who worked on the job were punctual, reliable, tidy, friendly, professional, trustworthy and very efficient. We were expecting a lot of mess in the house but were pleasantly surprised by the lack of it!

Sati and his team made very helpful suggestions along the way and made the whole process extremely painless. The work was originally quoted to take 4 weeks, but was completed ahead of schedule (including painting, electrical work and some plumbing) which was a huge bonus.

We are really happy with the tanking job that they did and highly recommend Iceberg.

Paul & Nicki Thandi

3 chamber conversion into bedroom, cinema and bathroom

We are so happy with our basement conversion.  It has given the house loads more space to grow into. The standard of work was very high and the guys are very friendly. They helped us overcome challenges throughout the project and made sure the job got finished to our expectations. We wish them every success in the future and hope their business continues to thrive.


1 room with en-suite, requiring underpinning and new railings

We looked at a number of builders to convert our basement into living space. But you were clearly the most expert and we valued your specialist knowledge throughout the conversion. The final product now my daughter’s bedroom with ensuite, exceeded our expectations for quality Thank you

Peter Radford

3 chambers converted to open plan living space

We had a cellar conversion on our period town house in central Warwick. There were two existing cellars separated by a large void that was filled with rubble. The requirements of the project were to join the two cellars to produce a large habitable area to be used as a home cinema and study. The work to be carried out included considerable excavation, structural alterations, and complete damp proofing. A detail specification for the work describing every stage was produced, along with a corresponding payment schedule. All the work was carried out on time and within the specified budget. The staff were polite and courteous and preformed the work with minimal disruption which was particularly important as the property was in the conservation area and had other properties within very close proximity. The work was carried out to a very high standard with any problems that were encountered being resolved with minimal issue. Their ownership of every part of the project and their “can do” attitude completely de-stressed the project for us and delivered a fantastic additional living space to our home.

Excavating to create a new room

“We were confident in our selection from the start; they were clearly experts in basement conversions and explained everything to us clearly throughout the process – including those elements which popped up through the build. They were happy to meet with us at our convenience and we appreciated the regular catch-ups and joint decision-making. The team worked hard on all aspects of the excavation, tanking and re-fitting, ultimately creating a great office and family room from what started off as a small, dark chamber and an enclosed void. They brought in a great team to finish the project off, including external works to create a new front garden, with all working to a high standard. We’re delighted with the final results.”

Richard Bish

1 room with en-suite

The boys have done a fantastic job converting our cellar from a damp, dark chamber to a light, spacious, comfortable, en suite double bedroom. From start to finish the level of customer service from the team was excellent and nothing was ever to much trouble. Time and again they put themselves out at inconvenient times to meet with us and discuss the progress of what was a challenging project and how we could move it forward to best suit our needs. The quality of work throughout was of the highest order and the finished product top class. To find tradesman so trustworthy, personable and professional is worth it’s weight in gold in today’s day and age and I would recommend them without hesitation to anyone. I certainly intend to use them again in the future.


Large scale basement conversion to include cinema and bar

“I’m happy to provide a reference in regard’s to the work you carried out for my house. It was a big job which involved underpinning, several walls were taken out, a tanking system was fitted and beams installed. Internal works were also carried out which involved plastering, plumbing, wiring, bath room, painting, new staircase and plus skirting.

I had contacted several reputable contractors in the area, but you were by far the most efficient and knowledgeable when it came to the structural aspect of the job as well as understanding my ‘demanding’ requirements. I have been very pleased with the work carried out, as I feel it was too a high standard, on budget and importantly on time. I have no hesitation in recommending your company.”


Repair previously damaged water proofing system

“I have a basement property in Leamington Spa. Having moved in knowing there were issues with the property I intended to carry out a renovation. They tackled the issues I had professionally and scientifically. They were the only firm that measured the problem with specialist equipment. They carried out initial surveys which found various underlying issues that had not be found by others. I instantly knew that they were the main contenders because of their method of investigation, arriving 3 time to confirm their method of solution. Where I had other quotes, who offered to effectively patch up, the problem areas,
The work carried out completely renovated my basement property, they were, punctual, tidy, friendly and accommodating. They especially took interest in walking me through each section of development and explained their thought process, as to why they had reached specific conclusions. I am extremely happy with the work that has been carried out, and they are also confident with the jobs they take on by offering longer guarantees than others. I am in no doubt that I had the best choice for basement renovations and would not hesitate in using them again.”

Sebastian Granville
