Highlights
"Chris done a superb job and was great at keeping me up to date at all times with the job and progress. Really happy with the job and the clean up afterward was perfect. Really pleased with everything. Thank you!"
"Chris came to us to install a new window and we could not be happier. He was upfront and communicative about costs and timelines, he stayed on top of suppliers and let us know how they were getting on, he arrived exactly when he said he would and completed the work to a high standard. Overall an excellent experience and we would definitely use Concept again if we have future building work."
"After me choosing the door design from various catalogues, Chris and his Concept team got straight to work ordering it, then when delivered, installing it, keeping me regularly posted along the way. However, I was unhappy with the short leverage of the delivered door’s internal locking mechanism. Despite several efforts by Chris to make it open any easier, then chasing the manufacturers to replace it, Chris replaced it himself. Initially temporarily, then permanently. In doing so, I felt he went the extra mile to get what the customer wanted, whilst keeping me informed of progress throughout."

Smart checks
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.
