Highlights

"Would highly recommend John and his dedicated team of skilled professionals for either a full house renovation or smaller projects. John’s experience and problem-solving makes for a great customer experience, he is calm under pressure and brilliant at managing within budget and on time. We had our whole house renovated including some construction repairs and we couldn’t fault John or his team. He is competitively priced and strives for a high spec finish. He took all the stress out of the job for us."

"We recently had John Jarvis remove an internal load-bearing wall and install a steel beam, and the experience was exceptional from start to finish. Both John and Andy approached the project with true professionalism, working with precision, care, and an evident pride in their craft. John himself was an absolute pleasure to meet — incredibly knowledgeable, reassuringly experienced, and genuinely friendly throughout the entire process. His attention to detail and commitment to achieving the highest standard of finish were clear in every aspect of the work. My partner and I are absolutely delighted with the results, and we have already recommended John to friends and family. A first-class service from a team you can trust completely."

Would highly recommend John. Repaired brickwork to our glasshouse. If you need a professional, look no further!

Before you hire a builder

Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
