Conversions - General- 8 Sep 2022
Charlie and his team were outstanding from start to finish of our project, which included the conversion of an empty space into a shower room and the full renovation of an adjoining bedroom. All costings were transparently produced and were within our budget area and the standard of work has been fantastic.

Latest review:
I met Rob in November 2020 when I employed him to do a full renovation of my home including an extension and remodel. Rob is a great communicator and talked me through every part of the job, which can be daunting when you're ripping your own house apart. He listens, gives honest advice and is very fair in his approach. No request is too much for him and he always goes out of his way to help. He has a great team who I thoroughly enjoyed having on site and they actually turn up! They have given me the most perfect home I could have wished for, and that's thanks to Rob taking on the same vision as me when we started this Reno. I've since employed Rob to complete works on my mums house and at another renovation I have at a rental property.

Tiling- 3 Dec 2017
We used Neil initially for the tiling of the whole downstairs of our house, porch, hall, 2 living rooms, kitchen and conservatory. We were happy with previous reviews and comments and his quote was competitive so we went with him and were very happy with all works, and we asked him to also do some pipe works to radiators, plastering and laminate flooring which he did whilst here and completed all the works in just under 3 weeks taking all building waste with him at end of job. He and his mate Ronnie were very trustworthy and we left them with a key to let themselves in and lock up whist we were in work during the day. More than happy to recommend Neil and would use him again if we needed any further works.

Extensions- 21 Nov 2021
Lewis and his team have been absolutely amazing from beginning to end. We wanted to knock through our dining room and kitchen wall to make a large family living space and utility area at the back of our garage. They supported us through all the drawings and building control regs. Always at the end of the phone for any advice. They remained on budget and on time, even when we asked for some extras to be done along the way Lewis was always happy to accommodate what he could. It was clear that his intention was not only to meet our expectations but to exceed them. We are very grateful for the hard work Newbridge developments put into to help us achieve the home we wanted. I would highly recommend them to anyone.

Boarding ceilings Insulating walls Full plastering Joinery work Loft hatch Skirtings and architraves throughout UPVC back door. The work was carried out in a timely and tidy fashion, I’m really happy with the work completed so far. James has a wealth of knowledge, which has been incredibly helpful. Also the most important, he turns up when he says he will and stays to get the job completed to a very high standard. I found his quotes very competitive, he sources quality materials at great prices, so much so I have him returning to do more work in the next few weeks.

What qualifications and experience do you have as an extension builder in St Helens?

An extension builder in St Helens should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in St Helens?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the St Helens extension builder’s ability to deliver a result that meets your expectations.
