Extensions- 22 Dec 2021
We could not be happy with the work that has been done by SJC Construction. They have gone above and beyond and very true to their word! The work was completed to a high standard in exactly the quoted time frame, exactly to the quoted price! They have made the whole process stress free and genuinely are a lovely group of guys, polite and efficient! Will be continuing to use them now for the rest of our work on our property and would be our first choice if in the future any more building work/ renovations need to be done :)

We did not go ahead with this job as we did not purchase the property, however, Craig and his team phoned me and explained to me over the phone what is needed and provided me an estimate over the phone which is what I was looking for. This helped me and put in to context what I was dealing with. Thanks very much.

Carpentry- 27 Jul 2025
Florin was great, he arrived promptly and got to work straight away. We had a really tricky door to fit to a wonky frame. Rather than trimming the door (which was pre finished in a semi gloss paint), he painstakingly chiselled back the frame to make it fit. Other people wouldn’t have done that and the finish would have been terrible if the door was trimmed. Well done Florin! He also fitted a recessed handle and lock system for a pocket door. We’ve already hired him again for some more work.

Carpentry- 17 Oct 2025
Nico did a fantastic job. The new wardrobe doors look amazing and fit perfectly after adjusting to fit the older door frames which had settled and moved slightly out of alignment over the years. Better than the original ones. The bedroom doors were replaced and fitted to open to the correct side of the rooms. The broken stair was expertly cut and fitted and matched perfectly to the rest of the stariway. Very solid and completely squeek free. Built to last a very long time. Nico is very reliable, dependable and highly skilled. I highly recommend him for any carpentry work needed.

Tony & Nicola Nugent 7 Bramley Gardens South Oxhey Hertfordshire WD196YD 07892 683 819 Whilst requesting quotations from contractors we came across Martin davies and requested if he could visit and quote us for a single floor extension. As this was a big deal for us financially I needed to make sure I was doing the right thing and ended up getting around 7 quotations from different builders. Martins quote was very competitive and after meeting him we decided to go with him. For us it was a great move especially as we have never done anything like this before. Martin from the start has been great, he kept us up to date all the way through with what the next step is and what are options were whilst giving us ideas from his experience and knowledge, nothing ever seemed to be too much trouble, whether it was myself or my wife asking for additional bits or even rescuing our cat from the house roof ! The team Martin uses are also brilliant, really friendly and genuinely nice guys, Tom the Electrician was brilliant and again nothing was too much trouble. I have quite a few friends who also work in the building trade and all have commented on Martins work that it is done to a high standard, this includes my father who was a builder for over 30 years. I would highly recommend Martin and certainly will be using him in the future for more works, I’m more than happy to be contacted for further information, also happy if you would like to visit and take a look yourself!

Zen has helped transform our home, we’ve drawn a lot of confidence from his considered approach and thorough work ethic. He’s so far addressed the cause of cracks to exterior walls of our property and has provided lasting solutions. We also asked him to plaster our hallway and update the banisters for us, Zen has done a great job of reinforcing the strength of the original features whilst retaining the property’s character. Very good with pets too. Looking forward to the next project.
