We initially approached several building companies for a self-build project, but Jason stood out immediately. He was the only one who made time to visit our home, sit with us, review the drawings, and discuss estimated costs in detail. From the very first meeting, Jason was honest and transparent, highlighting potential pitfalls and questioning some of the optimistic estimates we’d received elsewhere. At one point, he told us candidly that he wouldn’t take on the project if he believed we might not be able to complete it due to hidden costs. That level of integrity was rare and deeply appreciated. Rather than simply saying “yes” to secure the work, Jason gave us sound advice, which ultimately led us to reconsider the self-build and instead purchase a property with fewer risks. We later decided to build an orangery and extend the house and had no hesitation in asking Jason to lead the project. From day one, he was proactive, managing every aspect of the build and bringing in trusted experts where needed. He even checked in with us while on holiday to ensure everything was progressing smoothly. Every stage of the build was handled with precision and care. We were consulted regularly, given opportunities to tweak the design, and add features like external lighting and power outlets. No request was ever a problem. When challenges arose, as they inevitably do with large extensions Jason offered clear options and practical solutions. The old adage “never a problem, always a solution” truly applies here. The choice of building materials was excellent, and the subcontractors reflected Jason’s high standards: polite, professional, and skilled. The build was completed on time, and although slightly over budget, we were made aware of potential overruns from the outset. Jason is honest, reliable, highly skilled, and incredibly personable. We’ve not only had a flawless building experience, we’ve also gained a trusted friend. I have absolutely no hesitation in recommending him.

Extensions- 31 Dec 2022
Jason was hired to build a single storey extension but I hired him to do the loft conversion. It went downhill from week 3. The build was to take 8 weeks, started on the 1/08 and still hasn’t finished. The initial quote was competitive but there were additional charges for work he told me had to be done that was not part of the initial price, this happened every week. Never discussed, I would get a text on a Friday evening telling me I had to pay more, thousands extra each time. He’s taken no responsibility for damages to our and our neighbours house, promised he would fix this yet I have had to pay additional costs to have this repaired myself. Jason changed roofers part way through, promised there would be no additional cost, but then asked for another £2,300, I found out later that he had hired new roofers he just met on a day rate without agreeing with me. The first carpenter worked one day, another was hired and these costs also increased. Our neighbours house has been damaged by Jason, the absolute minimum has been done to repair their roof, our neighbour continues to chase us for damages. The work is not to a good standard, walls not straight, floors uneven, floors not insulated even though I have paid extra for this, the roof rattles when it’s windy and building control say the smoke detectors are not up to code so have to be re done at additional cost. He has made numerous promises and none have been kept, Jason takes no responsibility and I regret ever hiring him.

Kitchen Fitting- 7 Jun 2021
Didn't turn up …. Nothing against Alan at all … he was very friendly, discussed the works and came across like a good honest chap But … he came to view the works but would not commit to a price. I appreciate there are some unknowns but given he had visited the house for 45 minutes to see what was needed I would assume he would be able to quote a price. He talked about if's, buts and maybe's which I was happy to allow for but this did feel like he was pricing for the 'worst case scenario'. I sent a further note around the tasks and anticipated timings, which he was happy with but it was frustrating that I only found out he was not coming on the day he was due. He was a good guy but disappointed he didn't turn up to complete the work, which was pretty simple around repairing cupboards, replacing shower tray (and cubicle if needed), repairing skirting & floor board).. After he didn't arrive, I asked him if he wanted to complete the work but he has not yet replied....
