Owen Bridgeman HOUSE REFURBISHMENT

Multiple Construction completed a refurbishememnt of our house as well as converting a downstairs Understairs cupboard into a WC. The work was completed to a high standard and any subsequent changes requested to Dan and his team were carried out with little fuss. I would recommend the company for building projects and jobs of this nature.

Tobi INTERNAL REFURBISHMENT

Multiple Constructions were fantastic from start to finish of our renovation project. We contacted them early and there was some delays on our side, Multiple Constructions were professional all the way through and communicated effectively even through the delays. The one stop model worked well for us as we could contact one person to answer all our questions and make twerks where it suited. The work consisted of installing spotlights, skirting boards, painting and plumbing. Which was all done to a very good standard. I personally appreciated the fact that he always responded and also had a wonderful sense of humour. THANK YOU DAN!

India Bathroom Installation & Remodel

Dan and his whole team were amazing. Ben and Leslie were here everyday, and in just over a week they’d completely gutted our old bathroom and refitted a new one perfectly. Kind, efficient, professional, quick, and with much expertise, I couldn’t recommend them more. The final price was slightly more than quoted but that was only because there was more work than I’d realised when I’d contracted them. I mention this to highlight that they came to me first to ask if the increase would be okay, and explained what it was for and why it would be necessary. Impeccably professional. Definitely will be using them again!

Tracey Bathroom Installation & Remodel

Dan and his team were very professional. They were always punctual, friendly and very knowledgeable. They did a great job completely refurbishing my bathroom, installing a new cooker, tiling kitchen and small passage. They completed the job on time and to a really good standard.

Yinka FULL HOUSE REFURBISHMENT

What started a completely stripping back and reinstalling 2 bathrooms turned into a whole house refurb and Dan and his team rose to the occasion. Dan was easy to deal with throughout the project, he listened, paid attention and understood what I needed do to be done and definitely delivered, I’m pleased with the outcome and highly recommend them. We have more things to do and we will definitely call them back for those. We are pleased with the service and the transformation of our home

Baron Lee EXTENSION LOFT CONVERSION AND INTERNAL REFURBISHMENT

Very happy with the work the guys did. As a newbie in this trepidicious property developing world. I had a specific budget to produce something separate to rent out atop a already occupied house. I needed someone who could fully handle the project without subbing the work to many trades. Which could end up costing me more than I'd budgeted. Dan and his guys were up to the task and they delivered ahead of the schedule on contract. I'm very pleased. The loft conversion with bedroom and en-suite bathroom has been excellent and is about to rent out.

Naij Marecan LOFT CONVERSION

Multiple Construction and team installed a Mansard loft conversion as a top floor flat for us. The project was not the easiest but they were up to the task. The council were a bit difficult from my experience dealing with them. From the first visit by the inspection bloke, Dan was able to liase and discuss with him the council's requirements on my behalf. Overall I'm delighted with the result of the work. The materials sourcing also saved us a lot of money

Carl Oliver EXTENSIVE PLUMBING PROJECT

This was a job very well done. The team of 5 guys installed our plumbing system including 2 bathrooms and 1 wet room. Our plumbing needed more pressure so Salamander recommended us 2 X 1000 litres tanks with a pumping system to improve the pressure. This had to be installed in our loft 4 floors up. Excellent plumbing work. As I'm very particular. The tiling work which included mosaics, hexagonal shapes as well as herringbone design needed a lot of skills. The result was flawless.

D S FLAT REFURBISHMENT

Dan and his crew did a great job on my bathroom. What first started as a bathroom project soon developed into doing my kitchen. I was pleased with the final product for the bathroom so got him and his team to do my kitchen. I also got him to do my paraquet flooring with skirting board throughout my home. All done to a top standard. Dan is a very professional worker and more importantly you can trust him 1000%. I was very comfortable with him from the get go. You will not find a more honest builder than him. as Dan came to the rescue and saved us thousands of pounds overall using his contacts with merchants and getting deals. I was impressed also by their neatness, attention to details.

Tun Than BATHROOM INSTALLATION AND REMODEL

Dan is friendly, instant quote after receiving the photos of the concealed cistern toilet due for replacement. Quote is reasonable, knows his work, attended on time, neat and tidy and I am happy with his standard of work.

Ray B. Ravenscroft BATHROOM INSTALLATION AND REMODEL

The Multiple Bathrooms guys installed a retro style bathroom for us. The wife had all the magazine clippings ready to go and just gave it to the team. I was really impressed with the flowing style of the operation. There really was a lot involved here considering we needed a toilet at the end of each day and they managed to do all that in 8 days. They hid all the pipes in the wall so the wall hung toilet made it all look feng shui when finished. Worth every penny and well deserved 5 stars.

Mandy FULL HOUSE RENOVATION

Dan and his team did an incredible job in renovating our home. Cloakroom, family bathroom and ensuite bathroom, and the installation of new boiler. We were so impressed by the work ethic of the team and ease of communication. It is a pretty big project for us, especially we are the newcomers from Hong Kong. To save our purchases, Dan let us to enjoy the good prices through Topps Tiles and Victoriaplum. We love the outcome of the products.
