Highlights
"Professional Builder, Bliss contacted me the next day to see the work need to be done and started the following day. Honest reliable all round builder that completed the work within 4 days so I can definitely recommend there services."
"Bis is professional, knowledgeable and friendly. I highly recommend!"
"Bis has completely transformed yet another space for us, we are over the moon with the results. The works included the removal of wall to incorporate a cupboard, considerably increasing the size of the bathroom. It was gutted completely and reconfigured, the works completed to a very high standard (I am exceptionally keen eyed and fussy!). Bis is a pleasure to be around, tidy, punctual, transparent with costs and a great communicator ensuring 5* customer satisfaction."

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.
