Architecture- 20 Nov 2016
This is the first time we are carrying out an extension work at our property. Sean worked with us from a very early stage, prepared the drawings, coordinated with the council and ensured that we received the building approval on time. He was always available to advice us (when requested) on design challenges, choosing installers and material choices which we found very helpful. We are very happy with his work and thoroughly recommend him.

Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.

Carpentry- 7 Sep 2021
The cladding was due to start yesterday, Monday 6th of September. In the weekend, I was told they would come do a site visit on Monday instead of starting the job. They came on site yesterday morning and nothing was said about any issues. They said they would start the next day, Tuesday. I got a call at the end of the afternoon (around 5 pm) yesterday to be told suddenly that there are many problems; not levelled portions of frame (which can be easily rectified), no toilet on site (which they knew about - they knew also that the public toilet is only 50 m away), access problems which they also knew about ect... Suddenly a multitude of problems arised! They wanted more money. It is very obvious that they found another job somewhere. I would classify this sort of behaviour simply as not honest. Also expensive- I was quoted £4000 to clad a tiny first-floor(38 m2) . The overall cladding would be 75 m2 in total. Disappointing.

Martin is over qualified for a handy man role, being a Quantity surveyor but he expressed to me the satisfaction he gets from doing DIY jobs for people. His work is seamless and precise. He completed all the jobs given in quick time, with minimal stress and mess for me. I would 💯% recommend JJ Structural Jacqueline Davis

I would definitely recommend Step-Up Contractors - they have done a really fantastic and great quality job of refurbishing our bathroom and ensuite shower room. They were very professional, friendly and communicated really well with us throughout the whole process. They tidied up every evening before they left and were very considerate. They did such a good job that we have asked them to come back soon to complete kitchen flooring work for us!

Extensions- 22 Apr 2019
Richard and his team have always been very hard working, respectful and professional throughout the project. We have had an extension, utility and bathroom/toilet renovation and we are very happy with the quality of work. It has transformed our home into a beautiful living space. Richard was very helpful when giving advice on materials we were choosing. The team were very accommodating to our needs, easy to work with and always tidied up after themselves. The payment schedule made it easy to keep on top of the budget and pay for any optional extras along the way. The building work was completed within the set timescale and to a high standard. We would highly recommend Lux for any building/renovation work.

What experience do you have with similar extensions in Swanley?
